Comment Date:  February 3, 1995
Reply Comment Date:  February 21, 1995
       By the Commission:
                               INTRODUCTION
       1.  By this action, the Commission proposes to simplify the rules for the common
carrier and private operational fixed services, currently contained respectively in Parts 21 and
94 of the Commission's Rules, and to consolidate those rules into a new Part 101.  The key
objectives in this Notice of Proposed Rulemaking (Notice) are to restructure the fixed
microwave rules so that they are easier for the public to understand and use, to conform
similar rule provisions to the maximum extent possible, to eliminate redundancy, and to
remove obsolete language.  We are also taking this opportunity to review the need for and
impact of certain regulatory requirements and policies.
        2.  Common carrier microwave services and private operational fixed microwave
services share many of the same frequency bands and use substantially the same equipment.
As a result of recent changes that are discussed below, the interference standards, antenna
standards, and coordination procedures for private and common carrier fixed microwave
services have further converged.  This rulemaking is an effort to conform filing, processing,
operational, and technical requirements for services that are technically similar and, thereby,
to gain significant economies and alleviate confusion to the public.
                                BACKGROUND
        3.  Communications services that use the microwave spectrum for fixed services
include common carriers (currently regulated by Part 21 of the FCC Rules), common carrier
multiple address systems (Part 22), broadcasters (Part 74), cable TV operators (Part 78), and
private operational fixed users (currently regulated by Part 94).  The radio frequency spectrum
is allocated among these services on either a shared or an exclusive basis.  When different
service users have similar needs, they are sometimes required to share spectrum bands.
        4.  Of the services listed above, the common carrier and private operational fixed
microwave users are the most similar in technical requirements and share the most frequency
bands.  The convergence of the common carrier and private operational fixed microwave
technical standards has occurred over the last decade as a result of several rulemaking
proceedings.  Recently, a further convergence of these two services occurred as a result of
the reallocation of five bands above 3 GHz on a co-primary basis to the common carrier and
private operational fixed microwave licensees that are relocating from the 1850-1990,  2110-
2150, and 2160-2200 MHz  bands (2 GHz bands) to accommodate Personal Communications
Services (PCS) and other emerging technologies.  Although the emerging technologies
proceeding resolved all the technical issues necessary for this reallocation, there were other
technical matters raised in the proceeding, which were not considered critical to the 2 GHz
microwave users' relocation to other regions of the spectrum, that were left to be settled in a
future proceeding.
        5.  Also, as a result of the emerging technologies spectrum reallocation and the
resulting increase in frequency band-sharing, common carrier and private microwave industry
members have united to develop joint interference standards and coordination procedures.
For over a year, a subcommittee of the Telecommunications Industry Association's Fixed
Point-to-Point Microwave Engineering Committee (TIA TR14.11 Interference Criteria
Engineering Subcommittee) has held joint meetings with the National Spectrum Managers
Association (NSMA), a group of frequency coordinators for Part 21 applicants, to determine
interference criteria for Part 21 and Part 94 users.  This collaboration has resulted in a revised
TIA Telecommunications Systems Bulletin TSB 10-F, "Interference Criteria for Microwave
Systems," (TSB 10-F) which was adopted by the microwave industry on May 31, 1994.
Representatives from both the TIA fixed microwave group and the NSMA have met with
Commission staff to discuss the benefits of common technical standards, processing
procedures, and consolidated rules for common carrier and private operational fixed
microwave users.
        6. Another factor necessitating this proceeding is that the majority of the license
application processing for the Part 21 and Part 94 microwave services is now being handled
by the Wireless Telecommunications Bureau's Licensing Division in Gettysburg,
Pennsylvania.  Because the application processing for these services was formerly performed
by different Commission offices, the processing practices and policies differed.  This
proceeding seeks to bring uniformity to the fixed microwave application processing
procedures.
        7.  The Part 21 and Part 94 rules need to be consolidated, conformed, and updated to
allow the microwave industry to operate as efficiently as possible without being hampered by
obsolete regulations.  Because of the commonality of major portions of the existing common
carrier and private operational fixed microwave rules and the industry move to create common
standards and coordination procedures, we believe it would be beneficial to consolidate these
rules into one comprehensive part.  At the same time, this proceeding provides us with an
opportunity to improve the organization of the microwave rules, to simplify them, to eliminate
unnecessary language, and to make other substantive amendments.  We expect that a new
consolidated Part 101 will result in major benefits.  First, the public will benefit because of a
much simplified and streamlined licensing process.  Second, the improvements in processing
efficiency will save scarce Commission resources and free staff time to improve service to the
public.  Third, we expect the proposed rules to encourage more efficient use of the microwave
spectrum.  Finally, common technical standards for common carrier and private microwave
equipment may lead to economies of scale in microwave equipment production and, thus,
lower equipment prices to users.
                                DISCUSSION
        8.  Proposed Part 101 is approximately 65 percent the volume of the current common
carrier and private radio fixed microwave rules. This reduction results from the elimination of
repetitive sections such as definitions, application procedures, and processing procedures, the
elimination of unnecessary language, and the consolidation of the remaining rules.  In the
paragraphs below we address the proposed changes for each subpart and section of the rules,
other than proposed changes that are editorial in nature or that concern only renumbering of
existing rule language.  Appendix B, entitled "Cross-Reference Index," shows the disposition
of each existing rule in Parts 21 and 94.
        9.  We welcome comments on whether the scope of our consolidation effort is
appropriate.  We ask that comments identify the subject of their remarks, whenever possible,
by citing the proposed section number of a rule (with cross-reference to the old rule as
necessary).  This identification will expedite and simplify our review of the comments on the
many proposals contained in this Notice.
General Requirements
        10.  Definitions.  We propose to make minor editorial changes in the definitions where
appropriate.  In instances where a definition now appears in more than one rule section and is
phrased inconsistently, we propose to use the phrasing that we believe to be the most precise.
In cases where a definition appears in Part 2 of the Rules as well as in another part, the
proposed Part 101 definition adopts the Part 2 definition in order to conform with either the
International Telecommunication Convention or the international Radio Regulations.
Additionally, we propose to change the name and all relevant terms related to the Private
Digital Termination System service to match the name and terms of the identical Common
Carrier Digital Electronic Message Service.  See proposed Section 101.3.
Applications and Licenses
          11.   General Application Requirements.  We propose to eliminate several application
showings that are currently required of common carrier microwave applicants under Part 21 of the
rules, but which are not essential for processing these applications.  We request comments on each of
these proposals.  First, we propose to eliminate the financial showing required under  21.13(a)(2)
and 21.17.  Lack of financing has generally not been a problem in the common carrier services being
transferred to Part 101, and we consider a certification of financial ability unnecessary in these
services.  Second, we propose eliminating the public interest showing required under
 21.13(a)(4).  We tentatively conclude that the public interest will generally be served by granting
applications in these services that meet all the Commission's other rules and requirements, and that a
separate statement from the applicant pursuant to  21.13(a)(4) is unnecessary.  We also note that the
Commission can still request a separate public interest showing if this is deemed necessary in any
particular case.  Third, we propose eliminating the requirement that applicants submit a copy of any
franchise or other authorization when such authorizations are required by local law.  See  21.13(f).
We request comments on whether we should replace this application showing with a rule, similar to
that contained in Part 22 of the rules, stating that applicants must comply with all local franchise or
authorization requirements, obtain any local authorizations by the end of the construction period, and
notify the Commission if local authorization is denied.  See  22.13(f).  Fourth, we propose
eliminating showings regarding control over the station, see  21.13(g), and maintenance procedures,
see  21.15(e).   We request comments on whether we should replace these showings with a general
rule describing a licensee's responsibilities for maintenance and control of the station and requiring
that maintenance contracts must be in writing.  See  22.205.  We also request comments on whether
we should continue to require the address and telephone number of a maintenance center or person
responsible for technical operation, see   21.15(e)(1) and Item 18 of FCC Form 494 ("Application for
New or Modified Microwave Radio Station License Under Part 21"), or whether this requirement is
unnecessary and should also be deleted.  Fifth, we propose to eliminate the vertical profile sketch, see
 21.15(c), and the site availability showing, see  21.15(a), as these showings are not necessary for
processing and lack of site availability has not been a problem in the common carrier services being
transferred to Part 101.  Sixth, we request comments on whether the public interest showing currently
required of applicants in the Point-to-Point Microwave Radio Service pursuant to   21.706(a) should
be retained or deleted.  We also propose to allow electronic filing for all fixed microwave services
authorized under Part 101 as is currently allowed for private land mobile applications.  See proposed
Sections 1.743, 1.913, and 101.37.  Finally, we request comments on what requirements we should
adopt regarding retention or posting of the station license.  See e.g.  21.201, 22.201, and 94.107.
        12.  Licensee Qualifications and Consummation of Assignments and Transfers. Under Part 21,
applicants and licensees are currently required to provide ownership and character information on FCC
Form 430 ("Licensee Qualification Report"), see  21.11(a), and to disclose the real party in interest
behind the application pursuant to  21.13(a)(1).  See also  21.305.  We request comment on
precisely what ownership (including partnership) and character information we should continue to
require of common carrier applicants and licensees under the new Part 101.  In addition, under
 21.11(d), (e), and (f), applicants are required to complete assignments or transfers of control within
45 days of the date of authorization and to notify the Commission within 10 days of consummation.
In the common carrier services being transferred to Part 101, applicants frequently request extensions
of time to complete assignments or transfers.  Such requests are routinely granted.  Based on
this experience, we request comment on whether the time for consummation of assignments
and transfers should be extended to 360 days or longer, or whether applicants should be
allowed merely to notify the Commission of failure to consummate, rather than requiring
applicants to file, and the Commission to grant, repeated extension requests.  We also propose
to eliminate the requirement for common carriers to notify the Commission within 10 days of
consummation.
       13.  Commencing Operation.  With regard to the requirement for stations to be placed
in operation within a certain period after the date of grant, it has been common practice
among some applicants to request and obtain a modification of their license and thereby
obtain additional time within which to be in operation.  Some applicants repeated this
procedure several times, thereby extending their operational deadline far beyond the period
contemplated by the rules.  In response to these perceived abuses, the Commission's Private
Radio Bureau Licensing Division issued a Public Notice clarifying that a station must be
placed in operation within the time required by current  94.51 irrespective of whether the
licensee had been granted an amendment to its station authorization.  We propose to codify
this longstanding interpretation of our rule.  See proposed Section 101.63.
        14.  Although current  94.51 requires that private fixed microwave stations be placed
in operation within a time certain, it does not define what constitutes operation for purposes
of the rules.  In the past, several applicants have argued that the transmission of color bars
or other types of strictly test signals satisfies the rule's requirement of being in operation.
This interpretation has been uniformly rejected by the staff.  Applicants have also argued that
the  94.51 requirement of being in operation is satisfied as long as the station is simply
capable of transmitting intelligence.  The staff, however, has consistently informed the public
that the mere capability of transmission does not satisfy the requirement of being in operation.
We are proposing in Section 101.67(d) to make it clear that only the transmission of
operational signals is sufficient to satisfy the "in operation" requirement and that neither the
capability of transmission nor the transmission of color bars or similar test signals satisfies the
requirement to be in operation.   We are proposing to apply this requirement to both private
and common carrier fixed microwave users, as the underlying basis for this proposal, efficient
spectrum usage, applies equally to both groups.  We request comment on whether this
requirement is necessary or applicable for common carrier licensees under proposed Part 101.
Technical Standards
        15.  Frequency Availability Chart.  A new frequency availability chart has been placed
in the proposed rules (proposed Section 101.101) for the convenience of licensees and
applicants.  In addition to showing the frequency availability for private and common carrier
users, it also shows other services, such as broadcast, cable, PCS, MDS, and ITFS, that share
the same bands.  More specific technical information for the common carrier and private
microwave services are contained in rule Subparts G through J.
        16.  Coordination Procedures and Interference Standards.  In the Second Report and
Order in ET Docket 92-9, the Commission adopted the current Part 21 coordination
procedures and the current Part 94 interference standards for the relocated common carrier
and private operational fixed microwave users.  As stated above and in the Second Report
and Order, the common carrier and private microwave industry members have united to
develop joint interference standards and coordination procedures.  We propose, therefore, to
apply the same coordination procedures and interference standards to all bands for both
private and common carrier fixed microwave services.  In addition, we propose to modify the
present coordination procedures and interference protection standards to be consistent with the
TIA industry standards.  See proposed Sections 101.103 and 101.105.
        17.  Transmitter Power Limitations.  In addition to merging the transmitter power table
from Parts 21 and 94, we also propose to eliminate the values for maximum allowable
transmitter power, while retaining the values for Equivalent Isotropic Radiated Power (EIRP).
See proposed Section 101.113.   We are proposing to allow a maximum EIRP of + 55 dBW
for all point-to-point microwave bands from 4 GHz to 40 GHz, to allow for increased path
reliability on long paths and to set a common standard for all bands.  See proposed Section
101.113.   This proposal is based partly on TIA recommendations.  Comsearch also
proposed a maximum allowable EIRP of +55 dBW in an earlier proceeding.   Comsearch
points out that in Part 25 of the Rules, the terrestrial station EIRP used to determine
frequency coordination distance in the 4, 6, and 11 GHz bands is +55 dBW, which
corresponds with the International Telecommunications (ITU) Radio Rules and Regulations.
The Commission decided not to act on that portion of Comsearch's petition, instead deferring
consideration of maximum authorized power, antenna standards, and ATPC to a future
proceeding.  We seek comment on whether increasing the transmitter power limitations as
proposed would have any negative impact on any radio users.
        18.  Automatic Transmitter Power Control.  ATPC is a feature of digital microwave
radio that automatically adjusts transmitter output power based on path fading detected at the
far-end receiver(s).   In the emerging technologies/relocation proceeding, commenters
proposed that ATPC should be explicitly authorized in the rules.   In response, the
Commission clarified in the rules that ATPC is permitted up to a 3 dB increase in power and
encouraged industry groups to explore in greater detail under what circumstances ATPC
should be authorized and whether a greater increase in power than 3 dB would be
appropriate.  We have reviewed the ATPC guidelines in TSB 10-F and are still uncertain of
the necessity of including explicit provisions for its use in the rules.   We seek comment on
whether it is necessary to have TIA's recommendations for ATPC implementation included in
our Rules.  TSB 10-F contains provisions for up to three different power level specifications:
maximum transmit power, coordinated transmit power, and nominal transmit power.   We also
seek comment on how these recommendations for ATPC should be implemented under our
current licensing scheme, which authorizes only a single operating power level on each
license, with that power being the one used in the coordination process.   If the use of ATPC
as described in TSB 10-F were to be permitted, what changes would the Commission have to
make to its forms, licenses, and data base?
        19.   Antenna Standards.  All antenna standards for Part 101 services have been
consolidated into one rule section (proposed section 101.115).  Few substantive changes to the
antenna standards are proposed.  In the Docket 92-9 proceeding, commenting parties raised
concerns about our existing antenna standards, stating that the category A standards should be
updated and that a new detailed definition of congested areas should be specified to maximize
efficiency and permit full use of available bands.  The Commission does not have sufficient
information at this time to propose specific changes to these standards.
Developmental Authorizations
        20.  We propose to eliminate the general requirement that applicants report on any
patents applied for as a result of a developmental authorization.  This information is in the
public domain when the patent is granted, and our requirement is, therefore, duplicative.  We
also propose to modify the language concerning the confidentiality of developmental reports
to make it consistent with our general rules on requests for confidentiality.  The consolidated
rules continue the prohibition on providing service for hire with a developmental grant now
placed on common carriers and extends the prohibition against commercial operation of a
developmental grant to private radio operators.
                                CONCLUSION
        21.  In this Notice, we have proposed to amend the regulations for the common carrier
and private operational fixed microwave services by consolidating and simplifying their
present rule parts, contained respectively in Parts 21 and 94 of the Commission's Rules, to
create a new Part 101.  Our specific proposals are contained in the rules appendix.  We solicit
comment on them.  We also invite comment on any additional changes that can make the
Commission's microwave rules more "user friendly" and help the staff provide improved
service to the public.
                            PROCEDURAL MATTERS
        22.  Initial Regulatory Flexibility Analysis.  Pursuant to the Regulatory Flexibility Act
of 1980, the Commission finds as follows:
        A. Reason for Action
        This rulemaking proceeding is initiated to obtain comment regarding consolidation and
simplification of the microwave rules now contained in Parts 21 and 94 of Title 47 of the
Code of Federal Regulations.
        B. Objectives
        This action would reduce redundancy now contained in the rules and remove obsolete
rules and language.  It would also simplify and clarify the requirements for filing license and
other authorization applications, the processing of applications and other requests, and the
operation of common carrier and private operational fixed microwave stations.
        C. Legal Basis
        The proposed action is authorized by Sections 4(i) and 303(r) of the Communications
Act of 1934, as amended, 47 U.S.C.  154(i) and 303(r).
        D. Description, Potential Impact, and Number of Small Entities Affected
        This reorganization and revision of the common carrier and private operational fixed
microwave rules will reduce the volume of the rules by approximately 25 percent and make
them easier to use and understand.  Both the reduction in volume and consolidation of the
rules should improve their usefulness as they will be more easily understood by, and save
research time for, the public.  The benefits would accrue to all interested parties, large and
small entities alike.  We invite specific comment by interested parties on the likely magnitude
of the impact on small radio manufactures and suppliers.
        E. Reporting, Record Keeping, and Other Compliance Requirements
        There should be an overall decrease in reporting, record keeping, and other compliance
requirements.  The use of electronic filing alone should greatly reduce the amount of
paperwork required to be filed and increase speed of service.
        F. Federal Rules that Overlap, Duplicate or Conflict with these Rules
        None.
        G. Significant Alternatives Minimizing Impact on Small Entities Consistent with
Stated Objectives
        The objective of this proceeding is to minimize confusion, research time, record
keeping and recording for users of microwave radio frequencies.  We are unaware of other
alternatives that would be as desirable.  We solicit comments on this point.
        23.  Other Matters.  This is a non-restricted notice and comment rulemaking
proceeding.  Ex parte presentations are permitted, provided they are disclosed as provided in
the Commission's rules.  See generally 47 C.F.R.  1.1202, 1.1203, and 1.1206(a).
        24.  This action is taken pursuant to Section 4(i) and 303(r) of the Communications
Act of 1934, as amended, 47 U.S.C. Sections 154(i) and 303(r).
        25.  Pursuant to applicable procedures set forth in Sections 1.415 and 1.419 of the
Commission's Rules, interested parties may file comments on or before [30 days after
publication in the FR], and reply comments on or before [45 days after FR publication].  All
relevant and timely comments will be considered by the Commission before final action is
taken in this proceeding.  To file formally in this proceeding, participants must file an original
and four copies of all comments, reply comments, and supporting comments.  If participants
want each Commissioner to receive a personal copy of their comments, an original plus nine
copies must be filed.  Comments and reply comments should be sent to Office of the
Secretary, Federal Communications Commission, Washington, D.C.  20554.  Comments and
reply comments will be available for public inspection during regular business hours in the
Reference Center (Room 239) of the Federal Communications Commission, 1919 M Street,
N.W., Washington D.C.  20554.

        Antenna structures. The antenna, its supporting structure and anything  attached to it.
        Assigned frequency. The frequency coinciding with the center of the radio frequency channel in
which the station is authorized to work. This frequency  does not necessarily correspond to any
frequency in an emission.
        Authorized bandwidth. The maximum width of the band of frequencies permitted to be used by

"coordination distance" means the distance from an earth station, within which  there is a possibility of
the use of a given transmitting frequency at this earth station causing harmful interference to stations in
the fixed or mobile service, sharing the same band, or of the use of a given frequency for  reception at
this earth station receiving harmful interference from such  stations in the fixed or mobile service.
        Digital modulation. The process by which some characteristic (frequency,
phase, amplitude or combinations thereof) of a carrier frequency is varied in accordance with a digital
signal, e.g. one consisting of coded pulses or states.

    (a) Multipoint Distribution Service stations are generally intended to provide one-way radio
transmission (usually in an omnidirectional pattern) from a stationary transmitter to multiple
receiving facilities located at fixed points. When service is provided on a common carrier basis,
subscriber supplied information is transmitted to points designated by the subscriber.  When
service is provided on a non-common carrier basis, transmissions may include information
originated by persons other than the licensee, licensee- manipulated information supplied by
other persons, or information originated by the licensee. Point-to-point radio return links from a
subscriber's location to a MDS operator's facilities may be authorized in the 18,580 through
18,820 MHz and 18,920 through 19,160 MHz bands. Rules governing such operation are
contained in Subpart I of Part 101, the Point-to-Point Microwave Radio Service.

    (4) If the amendment specifies a substantial change in beneficial ownership or
control (de jure or de facto) of an applicant such that the change would require, in the case of
an authorized station, the filing of a prior assignment or transfer of control application under
section 310(d) of the Communications Act of 1934 [47 U.S.C. 310(d)]. Such a change would
not be considered major where the assignment or transfer of control is for legitimate business
purposes other than the acquisition of applications.
    (5) If the amendment, or the cumulative effect of the amendment, is determined by
the Commission otherwise to be substantial pursuant to section 309 of the Communications
Act of 1934.
(d) The applicant must serve copies of any amendments or other written communications upon
the following parties:
    (1) Any applicant whose application appears on its face to be mutually exclusive with
the application being amended, including those applicants originally served under   101.509;
    (2) Any applicant whose application has been found by the Commission, as
published in a public notice, to be mutually exclusive with the application being amended; and
    (3) Any party who has filed a petition to deny the application or other formal
objection, when that petition or formal objection has not been resolved by the Commission.
(e) The Commission may waive the service requirements of paragraph (d) of this section and
prescribe such alternative procedures as may be appropriate under the circumstances to
protect petitioners' interests and to avoid undue delay in a proceeding, if an applicant submits
a request for waiver which demonstrates that the service requirement is unreasonably
burdensome. Requests for waiver must be served on petitioners. Oppositions to the petition
may be filed within five (5) days after the petition is filed and must be served on the applicant.
Replies to oppositions will not be entertained.
(f) Any amendment to an application must be signed and must be submitted in the same
manner, and with the same number of copies, as was the original application. Amendments
may be made in letter form if they comply in all other respects with the requirements of this
chapter.
 101.31  Special temporary authority.
(a) In circumstances requiring immediate or temporary use of facilities, request may be made
for special temporary authority to install and/or operate new or modified equipment.  Any such
request may be submitted as an informal application in the manner set forth in Section 101.9
and must contain full particulars as to the proposed operation including all facts sufficient to
justify the temporary authority sought and the public interest therein.  No such request will be
considered unless the request is received by the Commission at least 10 days prior to the date
of proposed construction or operation or, where an extension is sought, expiration date of the
existing temporary authorization.
(b)  Special temporary authorization may be granted upon written request in the following
circumstances:
    (1) In emergency situations;
    (2) to permit restoration or relocation of existing facilities to continue communication
service;
    (3) to conduct tests to determine necessary data for the preparation of an application
for regular authorization;
    (4) for a temporary, non-recurring service where a regular authorization is not
appropriate;
    (5) in other situations involving circumstances which are of such extraordinary nature
that delay in the institution of temporary operation would seriously prejudice the public interest.
(c) The Commission may grant requests for special temporary authority without issuing the
public notice provided for in 1.962 of this chapter for periods not exceeding 180 days, if there
are extraordinary circumstances supporting the request and where delay in commencing
temporary operation would seriously prejudice the public interest.  Requests for special
temporary authorization not involving extraordinary circumstances may be granted without
public notice for a period of 30 days where an application for regular operation is not
contemplated or for 60 days pending or after the filing of an application for regular operation.
(d) Request for special temporary authority must contain the following information:
    (1) Name, address, and citizenship status of applicant;
    (2) Need for special action, including a description of any emergency or damage to
equipment;
    (3) Type of operation to be conducted;
    (4) Purpose of operation;
    (5) Time and date of operation desired;
    (6) Class of station and nature of service;
    (7) Location of station and points with which station will communicate;
    (8) Equipment to be used, specifying manufacturer, model number, and number of
units;
    (9) Frequency(s) desired.
    (10) Azimuth and beamwidth of major lobe of transmitting antenna and ERP;
    (11) Type of emission;
    (12) Description of antenna to be used, including height.
    (13) Certification that neither the applicant nor any party to the applicant is subject to
a denial of Federal benefits that includes FCC benefits pursuant to section 5301 of the Anti-
Drug Abuse Act of 1988, as required by 1.2002 of this Chapter.
 101.33  Who may sign applications.
See Part 1 of this chapter Sections 1.743 and 1.913, for practices and procedures governing
signatures on  applications,  amendments and related statements of fact..
       Processing of Applications
 101.35  Preliminary processing of applications.
(a) Applications received for filing are given a file number. The assignment of a file number to
an application is for administrative convenience and does not indicate the acceptance of the
application for filing and processing and does not preclude the subsequent return of the
application.
(b) Applications that are incomplete with respect to answers, supplementary statements,
execution, or other matters of a formal character will be considered defective and may be
returned to the applicant with a brief statement as to such defects.  If an applicant is requested
by the Commission to file any additional documents or information not included in the
prescribed application form, failure to comply with such request will be deemed to render the
application defective, and such application may be dismissed.  Applications will also be
deemed to be defective and may be returned to the applicant in the following cases:
    (1) Statutory disqualification of applicant;
    (2) Proposed use or purpose of station would be unlawful;
    (3) Requested frequency is not allocated for assignment for the service proposed;
    (4) The submitted filing fee (if required) is insufficient;
    (5) The application does not demonstrate compliance with the special requirements
applicable to the radio service involved;
    (6) The applications does not include all necessary exhibits;
    (7) The application fails to meet any other Commission requirements.
(c) Any application that has been returned to the applicant for correction will be processed in
original order of receipt when resubmitted if it is  received within 60 days from the date on
which it was returned to the applicant and the change does not involve a major amendment.  If
the application is not resubmitted within the prescribed time, it will be treated as a new
application and considered at the time other applications received on the same date are
considered.
(d) Applications considered defective under paragraph (b) of this section may be accepted for
filing if:
    (1) The application is accompanied by a request which sets forth the reasons in
support of a waiver of (or an exception to), in whole or in part, any specific rule, regulation, or
requirement with which the application is in conflict; or
    (2) The Commission, upon its own motion, waives (or allows an exception to), in
whole or in part, any rule, regulation or requirement.
 101.37  Public notice period.
(a) At regular intervals, the Commission will issue a public notice listing:
    (1) The acceptance for filing of applications and major amendments thereto;
    (2) Significant Commission actions concerning applications;
    (3) The receipt of applications for minor modifications made pursuant to Sec. 101.59;
    (4) Information which the Commission in its discretion believes of public significance;
and
    (5) Special environmental considerations as required by Part 1 of this chapter.
(b) A public notice will not normally be issued for any of the following applications:
    (1) For authorization of a minor technical change in the facilities of a proposed or
authorized station where such a change would not be classified as a major amendment to a
pending application, as defined by  101.29, or as a minor modification to a license pursuant to
 101.59;
    (2) For temporary authorization pursuant to  101.31;
    (3) For an authorization under any of the proviso clauses of section 308(a) of the
Communications Act of 1934 (47 U.S.C. 308(a));
    (4) For consent to an involuntary assignment or transfer of control of a radio
authorization; or
    (5) For consent to a voluntary assignment or transfer of control of a radio
authorization, where the assignment or transfer does not involve a substantial change in
ownership or control.
(c) Except as otherwise provided in this Part (e.g., Sec. 101.59), no application that has
appeared on public notice will be granted until the expiration of a period of thirty days following
the issuance of the public notice listing the application, or any major amendment thereto, or
until the expiration of a period of thirty days following the issuance of a public notice identifying
the tentative selectee of a random selection process, whichever is later.
(d) The listing of an application on public notice as accepted for filing does not indicate that the
application has been found by the Commission to be acceptable for filing and does not
preclude the subsequent return of the application.
 101.39  Dismissal and return of applications.
(a) Except as provided under paragraph (d) of this Section and under  101.41, any application
may, upon written request, be dismissed without prejudice as a matter of right prior to the
adoption date of any final Commission action or the application's designation for hearing or
comparative evaluation.
(b) Applicants for stations licensed under Subpart H (Private Operational Fixed Microwave
Service) may request the return of an application for correction without dismissal.
(c) A request to dismiss an application without prejudice will be considered after designation for
hearing, after selection through the comparative evaluation procedure of  101.51, or after
selection as a tentative selectee in a random selection proceeding, only if:
    (1) A written petition is submitted to the Commission and, in the case of applications
designated for hearing or comparative evaluation, is properly served upon all parties of record;
    (2) The petition is submitted before the issuance date of a public notice of
Commission action denying the application; and
    (3) The petition complies with the provision of  101.41 (whenever applicable) and
demonstrates good cause.
(d) Except as provided under  101.41, an application designated for inclusion in the random
selection process may be dismissed without prejudice as a matter of right if the applicant
requests its dismissal at least 2 days prior to a random selection proceeding.
(e) Dismissal for failure to prosecute or for failure to respond to official correspondence or
requests for additional information within a specified time period will be without prejudice prior
to its designation for hearing,  or tentative selection by the random selection process.
Dismissal may be with prejudice after selection of the comparative evaluation process, or after
selection as a tentative selectee in a random selection proceeding.
 101.41  Ownership changes and agreements to amend or dismiss applications or pleadings.
(a) Except as provided in paragraph (b) of this section, applicants or any other parties in
interest to pending applications must comply with the provisions of this section whenever:
    (1) They participate in any agreement (or understanding) which involves any
consideration promised or received, directly or indirectly, including any agreement (or
understanding) for merger of interests or the reciprocal withdrawal of applications; and
    (2) The agreement (or understanding) may result in either:
    (i) A proposed substantial change in beneficial ownership or control (dejure or
de facto) of an applicant such that the change would require, in the case of an authorized
station, the filing of a prior assignment or transfer of control application under  310(d) of the
Communications Act of 1934 [47 U.S.C.  310(d)], or
    (ii) Proposed withdrawal, amendment or dismissal of any application(s),
amendment(s), petition(s), pleading(s), or any combination thereof, which would thereby permit
the grant without hearing, comparative evaluation under of Sec. 101.51, or random selection of
an application previously in contested status.
(b) The provisions of this section will not be applicable to any engineering agreement (or
understanding) that:
    (1) Resolves frequency conflicts with authorized stations or other pending
applications without the creation of new or increased frequency conflicts; and
    (2) Does not involve any consideration promised or received, directly or indirectly
(including any merger of interests or reciprocal withdrawal of applications), other than the
mutual benefit of resolving the engineering conflict.
(c) For any agreement subject to this section, the applicant of an application which would
remain pending pursuant to such an agreement will be considered responsible for the
compliance by all parties with the procedures of this section. Failure of the parties to comply
with the procedures of this section will constitute a defect in those applications which are
involved in the agreement and remain in a pending status.
(d) The principals to any agreement or understanding subject to this section must comply with
the standards of paragraph (e) of this section in accordance with the following procedure:
    (1) Within ten (10) days after entering into the agreement, the parties thereto must
jointly notify the Commission in writing of the existence and general terms of such agreement,
the identity of all of the participants and the applications involved;
    (2) Within thirty (30) days after entering into the agreement, the parties thereto must
file any proposed application amendments, motions, or requests together with a copy of the
agreement which clearly sets forth all terms and provisions, and such other facts and
information as necessary to satisfy the standards of paragraph (e) of this section. Such
submission must be accompanied by the certification by affidavit of each principal to the
agreement declaring that the statements made are true, complete, and correct to the best of
their knowledge and belief, and are made in good faith.
    (3) The Commission may request any further information which in its judgment it
believes is necessary for a determination under paragraph (e) of this section.
(e) The Commission will grant an application (or applications) involved in the agreement (or
understanding) only if it finds upon examination of the information submitted, and upon
consideration of such other matters as may be officially noticed, that the agreement is
consistent with the public interest, and the amount of any monetary consideration and the cash
value of any other consideration promised or received is not in excess of those legitimate and
prudent costs directly assignable to the engineering, preparation, filing and advocacy of the
withdrawn, dismissed, or amended application(s), amendment(s), petition(s), pleading(s), or
any combination thereof. Where such costs represent the applicant's in-house efforts, these
costs may include only directly assignable costs and must exclude general overhead
expenses. [The treatment to be accorded such consideration for interstate rate making
purposes will be determined at such time as the question may arise in an appropriate rate
proceeding.] An itemized accounting must be submitted to support the amount of consideration
involved except where such consideration (including the fair market value of any non-cash
consideration) promised or received does not exceed one thousand dollars ($1,000.00). Where
consideration involves a sale of facilities or merger of interests, the accounting must clearly
identify that portion of the consideration allocated for such facilities or interests and a detailed
description thereof, including estimated fair market value. The Commission will not presume an
agreement (or understanding) to be prima facie contrary to the public interest solely because it
incorporates a mutual agreement to withdraw pending application(s), amendment(s), petition(s),
pleading(s), or any combination thereof.
 101.43  Opposition to applications.
(a) Any party in interest may file with the Commission a petition to deny any application for
which public notice is required.  All such petitions must:
    (1) Identify the application or applications including applicant's name, station location,
Commission file numbers and radio service involved with which it is concerned;
    (2) Be filed in accordance with the pleading limitations, filing periods, and other
applicable provisions of this Part and Part 1;
    (3) Contain specific allegations of fact (except for those of which official notice may
be taken), supported by affidavit of a person or persons with personal knowledge thereof and
be sufficient to make a prima facie showing that the petitioner is a party in interest and that a
grant of the application would be inconsistent with the public interest, convenience and
necessity;
    (4) Be filed within thirty (30) days after the date of public notice announcing the
acceptance for filing of such applications or major amendments thereto, or, identifying the
tentative selectee of a random selection proceeding (unless the Commission otherwise extends
the deadline); and
    (5) Contain a certificate of service showing that the applicant has been mailed a
copy of the petition no later than the date on which the petition is filed with the Commission.
(b) The applicant may file an opposition to any petition to deny and the petitioner may file a
reply thereto in which allegations of fact or denials thereof must be supported by an affidavit of
a person or persons with personal knowledge thereof and be clearly identified.  The applicant
must serve a copy of the opposition on the petitioner, and the petitioner must serve a copy of
its reply on the applicant.  The time for filing such oppositions and replies are provided in 
1.45.
(c) Notwithstanding the provisions of paragraph (a) of this section, before Commission action
on any application for an instrument of authorization, any person may file informal objections to
the grant.  The Commission will consider informal objections, but not necessarily discuss them
in a written opinion, if the objection is filed at least one day prior to action on the application
and the objection is signed by the submitting person with a disclosure of that person's interest.
Such objections may be submitted in letter form.  The limitation on pleadings and time for filing
pleadings provided for in  1.45 will not be applicable to any objections duly filed pursuant to
this paragraph.
(d) Petitions to deny not filed in accordance with paragraph (a) of this section will be treated as
informal objections.
 101.45  Mutually exclusive applications.
(a) The Commission will consider applications to be mutually exclusive if their conflicts are
such that the grant of one application would effectively preclude by reason of harmful electrical
interference, or other practical reason, the grant of one or more of the other applications. The
Commission will presume "harmful electrical interference" to mean interference which would
result in a material impairment to service rendered to the public despite full cooperation in
good faith by all applicants or parties to achieve reasonable technical adjustments which would
avoid electrical conflict.
(b) A common carrier application will be entitled to be included in a random selection  process
or to comparative consideration with one or more conflicting  applications only if:
    (1) The application is mutually exclusive with the other application; and
    (2) The application is received by the Commission in a condition acceptable  for filing by
whichever "cut-off" date is earlier:
    (i) Sixty (60) days after the date of the public notice listing the first  of the conflicting
applications as accepted for filing; or
    (ii) One (1) business day preceding the day on which the Commission takes  final action on
the previously filed application (should the Commission act  upon such application in the
interval between thirty (30) and sixty (60) days  after the date of its public notice).
(c) Whenever three or more applications are mutually exclusive, but not uniformly so, the
earliest filed application established the date prescribed in paragraph (b)(2) of this section,
regardless of whether or not subsequently filed applications are directly mutually exclusive with
the first filed application. [For example, applications A, B, and C are filed in that order. A and B
are directly mutually exclusive, B and C are directly mutually exclusive. In order to be
considered comparatively with B, C must be filed within the "cut-off" period established by A
even though C is not directly mutually exclusive with A.]
(d) Private fixed microwave applications for authorization under this Part will be entitled to be
included in a random selection process or to comparative consideration with one or more
conflicting applications in accordance with the provisions of 1.227(b)(4).
(e) An application otherwise mutually exclusive with one of more previously filed applications,
but filed after the appropriate date prescribed in paragraphs (b) or (d) of this section, will be
returned without prejudice and will be eligible for refiling only after final action is taken by the
Commission with respect to the previously filed application (or applications).
(f) For the purposes of this section, any application (whether mutually exclusive or not) will be
considered to be a newly filed application if it is amended by a major amendment (as defined
by  101.29), except under any of the following circumstances:
    (1) The application has been designated for comparative hearing, or for comparative
evaluation (pursuant to Sec. 101.51), and the Commission or the presiding officer accepts the
amendment pursuant to Sec. 101.29(b);
    (2) The amendment resolves frequency conflicts with authorized stations or other
pending applications which would otherwise require resolution by hearing, by comparative
evaluation pursuant to Sec. 101.51, or by random selection pursuant to Sec. 101.49 provided
that the amendment does not create new or additional frequency conflicts;
    (3) The amendment reflects only a change in ownership or control found by the
Commission to be in the public interest, and for which a requested exemption from the "cut-off"
requirements of this section is granted;
    (4) The amendment reflects only a change in ownership or control which results from
an agreement under Sec. 101.41 whereby two or more applicants entitled to comparative
consideration of their applications join in one (or more) of the existing applications and request
dismissal of their other application (or applications) to avoid the delay and cost of comparative
consideration;
    (5) The amendment corrects typographical, transcription, or similar clerical errors
which are clearly demonstrated to be mistakes by reference to other parts of the application,
and whose discovery does not create new or increased frequency conflicts; or
    (6) The amendment does not create new or increased frequency conflicts, and is
demonstrably necessitated by events which the applicant could not have reasonably foreseen
at the time of filing, such as, for example:
    (i) The loss of a transmitter or receiver site by condemnation, natural causes,
or loss of lease or option;
    (ii) Obstruction of a proposed transmission path caused by the erection of a
new building or other structure; or
    (iii) The discontinuance or substantial technological obsolescence of specified
equipment, whenever the application has been pending before the Commission for two or more
years from the date of its filing.
(g)  Applicants for the 932.5-935/941.5-944 MHz bands shall select a frequency pair.
Applicants for these bands may select an unpaired frequency only upon a showing that
spectrum efficiency will not be impaired and that unpaired spectrum is not available in other
bands.  During the initial filing window, frequency coordination is not required, except that an
application for a frequency in the 942-944 MHz band must be coordinated to ensure that it
does not affect an existing broadcast auxiliary service licensee.  After the initial filing window,
an applicant must submit evidence that frequency coordination has been performed with all
licensees affected by the application.  All frequency coordination must be performed in
accordance with  101.103 of the Commission's Rules.  In the event of mutually exclusive
applications occurring during the initial filing window for the 932.5-935/941.5-944 MHz bands,
applicants shall be given the opportunity to resolve these situations by applying for an
alternative frequency pair, if one is available.  To the extent that there are no other available
frequencies or to the extent that mutually exclusive applications remain after this process is
concluded, lotteries shall be conducted for each frequency pair among all remaining mutually
exclusive applications, assuming appropriate coordination with existing broadcast auxiliary
stations can be concluded, where necessary.  In the event of mutually exclusive applications
being received for these bands on the same day after the initial filing window has closed and a
subsequent filing window opened, lotteries shall be conducted for each frequency pair among
all mutually exclusive applications.
 101.47  Consideration of applications.
(a) Applications for an instrument of authorization will be granted if, upon examination of the
application and upon consideration of such other matters as it may officially notice, the
Commission finds that the grant will serve the public interest, convenience, and necessity.
(b) The grant will be without a formal hearing if, upon consideration of the application, any
pleadings of objections filed, or other matters which may be officially noticed, the Commission
finds that:
    (1) The application is acceptable for filing, and is in accordance with the
Commission's rules, regulations, and other requirements;
    (2) The application is not subject to comparative consideration (pursuant to  101.45)
with another application (or applications), except where the competing applicants have chosen
the comparative evaluation procedure of  101.51 and a grant is appropriate under that
procedure;
    (3) A grant of the application would not cause harmful electrical interference to an
authorized station;
    (4) There are no substantial and material questions of fact presented; and
    (5) The applicant is legally, technically, financially and otherwise qualified, and a
grant of the application would serve the public interest.
(c) Whenever the Commission, without a formal hearing, grants any application in part, or
subject to any terms or conditions other than those normally applied to applications of the
same type, it will inform the applicant of the reasons therefor, and the grant will be considered
final unless the Commission revises its action (either by granting the application as originally
requested, or by designating the application for a formal evidentiary hearing) in response to a
petition for reconsideration that:
    (1) Is filed by the applicant within thirty (30) days from the date of the letter or order
giving the reasons for the partial or conditioned grant;
    (2) Rejects the grant as made and explains the reasons why the application should
be granted as originally requested; and
    (3) Returns the instrument of authorization.
(d) The Commission will designate an application for a formal hearing, specifying with
particularity the matters and things in issue, if, upon consideration of the application, any
pleadings or objections filed, or other matters which may be officially noticed, the Commission
determines that:
    (1) A substantial and material question of fact is presented;
    (2) The Commission is unable for any reason to make the findings specified in
paragraph (a) of this section and the application is acceptable for filing, complete, and in
accordance with the Commission's rules, regulations, and other requirements.
    (3) The application is entitled to comparative consideration (under   101.45) with
another application (or applications); or
    (4) The application is entitled to comparative consideration (pursuant to  101.45)
and the applicants have chosen the comparative evaluation procedure of   101.51 but the
Commission deems such procedure to be inappropriate.
(e) The Commission may grant, deny, or take other action with respect to an application
designated for a formal hearing pursuant to paragraph (d) of this section or Part 1 of this
chapter.
(f) Whenever the public interest would be served thereby the Commission may grant one or
more mutually exclusive applications expressly conditioned upon final action on the
applications, and then either conduct a random section process (in specified services under
this rules part), designate all of the mutually exclusive applications for a formal evidentiary
hearing or (whenever so requested) follow the comparative evaluation procedures of  101.51,
as appropriate, if it appears:
    (1) That some or all of the applications were not filed in good faith, but were filed for
the purpose of delaying or hindering the grant of another application;
    (2) That the public interest requires the prompt establishment of radio service in a
particular community or area;
    (3) That a delay in making a grant to any applicant until after the conclusion of a
hearing or a random selection proceeding on all applications might jeopardize the rights of the
United States under the provision of an international agreement to the use of the frequency in
question; or
    (4) That a grant of one application would be in the public interest in that it appears
from an examination of the remaining applications that they cannot be granted because they
are in violation of provisions of the Communications Act, other statutes, or of the provisions of
this chapter.
(g) Reconsideration or review of any final action taken by the Commission will be in
accordance with Subpart A of Part 1 of this chapter.
 101.49  Grants by random selection.
(a) If an application for an authorization in the Digital Electronic Message Service (DEMS) is
mutually exclusive with another such application and satisfies the requirements of  101.45,
the applicant may be included in the random selection process set forth in  1.821, 1.822 and
1.825 of this chapter.
(b) Renewal applications will not be included in a random selection process.
 101.51  Comparative evaluation of mutually exclusive applications.
(a) In order to expedite action on mutually exclusive applications in services under this rules
part where the random selection process does not apply, the applicants may request the
Commission to consider their applications without a formal hearing in accordance with the
summary procedure outlined in paragraph (b) in this section if:
    (1) The applications are entitled to comparative consideration pursuant to Sec.
101.45;
    (2) The applications have not been designated for formal evidentiary hearing; and
    (3) The Commission determines, initially or at any time during the procedure outlined
in paragraph (b) of this section, that such procedure is appropriate, and that, from the
information submitted and consideration of such other matters as may be officially noticed,
there are no substantial and material questions of fact presented (other than those relating to
the comparative merits of the applications) which would preclude a grant under paragraphs (a)
and (b) of  101.47.
(b) Provided that the conditions of paragraph (a) of this section are satisfied, applicants may
request the Commission to act upon their mutually exclusive applications without a formal
hearing pursuant to the summary procedure outlined below:
    (1) To initiate the procedure, each applicant will submit to the Commission a written
statement containing:
    (i) A waiver of the applicant's right to a formal hearing;
    (ii) A request and agreement that, in order to avoid the delay and expense of a
comparative formal hearing, the Commission should exercise its judgment to select from
among the mutually exclusive applications that proposal (or proposals) which would best serve
the public interest; and
    (iii) The signature of a principal (and the principal's attorney if represented).
    (2) After receipt of the written requests of all of the applicants the Commission (if it
deems this procedure appropriate) will issue a notice designating the comparative criteria upon
which the applications are to be evaluated and will request each applicant to submit, within a
specified period of time, additional information concerning the applicant's proposal relative to
the comparative criteria.
    (3) Within thirty (30) days following the due date for filing this information, the
Commission will accept concise and factual argument on the competing proposals from the
rival applicants, potential customers, and other knowledgeable parties in interest.
    (4) Within fifteen (15) days following the due date for the filing of comments, the
Commission will accept concise and factual replies from the rival applicants.
    (5) From time to time during the course of this procedure the Commission may
request additional information from the applicants and hold informal conferences at which all
competing applicants will have the right to be represented.
    (6) Upon evaluation of the applications, the information submitted, and such other
matters as may be officially noticed the Commission will issue a decision granting one (or
more) of the proposals which it concludes would best serve the public interest, convenience
and necessity. The decision will report briefly and concisely the reasons for the Commission's
selection and will deny the other application(s). This decision will be considered final.
     License Transfers, Modifications, Conditions and Forfeitures
 101.53  Assignment or transfer of station authorization.
(a) No station license, or any rights thereunder, may be transferred, assigned, or disposed of in
any manner, voluntarily or involuntarily,  directly or indirectly, or by transfer of control of any
corporation or any other entity holding any such license, to any person except upon application
 to the Commission and upon finding by the Commission that the public interest, convenience
and necessity will be served thereby.
(b) For purposes of this section, transfers of control requiring Commission approval must
include any and all transactions that:
    (1) Change the party controlling the affairs of the licensee, or
    (2) Affect any change in a controlling interest in the ownership of the licensee,
including changes in legal or equitable ownership, or
(c) Requests for transfer of control or assignment authority must be submitted on the
application form prescribed by  101.17 of this chapter, and must be accompanied by the
applicable showings required by  101.19, 101.21,  and 101.55 of this chapter.
(d) The Commission must be promptly notified in writing when a licensee is voluntarily or
involuntarily placed in bankruptcy or receivership and when an individual licensee, a member
of a partnership which is a licensee, or a  person directly or indirectly in control of a
corporation which is a  licensee, dies or becomes legally disabled. Within thirty days after the
occurrence of such bankruptcy, receivership, death or legal disability, an  application of
involuntary assignment of such license, or involuntary  transfer of control of such corporation,
must be filed with the Commission,  requesting assignment or transfer to a successor legally
qualified under the laws of the place having jurisdiction over the assets involved.
(e) The assignor of a station licensed under this part may retain no right of reversion or
reassignment of the license and may not reserve the right to use the facilities of the station for
any period whatsoever. No assignment of  license will be granted or authorized if there is a
contract or  understanding, express or implied, pursuant to which a right of reversion or
reassignment of the license or right to use the facilities are retained as  partial or full
consideration for the assignment or transfer.
(f) No special temporary authority, or any rights thereunder, may be assigned or otherwise
disposed of, directly or indirectly, voluntarily or involuntarily, without prior Commission approval.
 101.55  Considerations involving transfer or assignment applications.
(a)  Licenses may not be assigned or transferred prior to the completion of construction of the
facility.  However, consent to the assignment or transfer of control of such a license may be
given prior to the completion of construction where:
    (1) The assignment or transfer does not involve a substantial change in or ownership
or control of the authorized facilities; or in
    (2) The assignment or transfer of control is involuntary due to the licensee's
bankruptcy, death, or legal disability.
(b) The Commission will review a proposed transaction to determine if the circumstances
indicate "trafficking" in licenses whenever applications  (except those involving pro forma
assignment or transfer of control) for  consent to assignment of a license, or for transfer of
control of a licensee,  involve facilities that were:
    (1) Authorized following a comparative hearing and have been operated less than
one year, or;
    (2) Involve facilities that have not been constructed, or;
    (3) Involve facilities that were authorized following a random selection  proceeding in
which the successful applicant received preference and that  have been operated for less than
one year.
At its discretion, the Commission may require the submission of an affirmative, factual showing
(supported by affidavits of a person or persons  with personal knowledge thereof) to
demonstrate that the proposed assignor or transferor has not acquired an authorization or
operated a station for the  principal purpose of profitable sale rather than public service. This
showing may include, for example, a demonstration that the proposed assignment or transfer is
due to changed circumstances (described in detail) affecting the licensee subsequent to the
acquisition of the license, or that the proposed transfer of radio facilities is incidental to a sale
of other facilities or  merger of interests.
(c) If a proposed transfer of radio facilities is incidental to a sale of other facilities or merger of
interests, any showing requested under paragraph (a) of this section must include an additional
exhibit that:
    (1) Discloses complete details as to the sale of facilities or merger of interests;
    (2) Segregates clearly by an itemized accounting, the amount of consideration
involved in the sale of facilities or merger of interests; and
    (3) Demonstrates that the amount of consideration assignable to the facilities or
business interests involved represents their fair market value at the time of the transaction.
(d) For the purposes of this section, the one year period is calculated using the following dates
(as appropriate):
    (1) The initial date of grant of the license, excluding subsequent modifications;
    (2) The date of consummation of an assignment or transfer, if the station is acquired
as the result of an assignment of license, or transfer of control of corporate licensee; or
    (3) The median date of the applicable commencement dates (determined pursuant to
paragraphs (d) (1) and (2) of this section) if the transaction  involves a system (such as a
Point-to-Point Microwave System) of two or more stations. (The median date is that date so
selected such that fifty percent of the commencement dates of the total number of stations,
when arranged in  chronological order, lie below it and fifty percent lie above it. When the
number of stations is an even number, the median date will be a value half way between the
two dates closest to the theoretical median).
 101.57  Modification of station license.
(a) Except as provided in  101.59, no modification of a license issued pursuant to this part (or
the facilities described thereunder) may be made except upon application to the Commission.
(b) No application for modification to extend a license construction period will be granted for
delays caused by lack of financing or for lack of site availability. Applications for time
extensions for other reasons must include a verified statement from the applicant showing that
the licensee has made  diligent efforts to construct the facilities and:
    (1) That additional time is required due to circumstances beyond the applicant's
control, in which case the applicant must describe such circumstances and must set forth with
specificity and justify the precise extension period requested; or
    (2) That there are unique and overriding public interest concerns that justify such an
extension, in which case the applicant must identify such interests and must set forth and
justify a precise extension period.
(c) Notwithstanding the provisions of paragraph (b), when a station license has been assigned
or transferred pursuant to  101.53, any extension of time will be limited so that the time left to
construct after Commission grant of the transfer or assignment will be no more than the time
remaining for construction at the date of the filing of the application for transfer or assignment.
(d) Modification of license is required for the following changes in authorized stations:
    (1) Any change in frequencies used;
    (2) Any change in antenna azimuth;
    (3) Any change in antenna beamwidth;
    (4) Any change in antenna or passive repeater location greater than 1 second or
which involves a requirement for special aeronautical study;
    (5) Any change in antenna polarization;
    (6) Any change in antenna height;
    (7) Any change in the size of passive reflectors or repeaters associated with the
facilities of an authorized station;
    (8) Any increase in emission bandwidth beyond that authorized;
    (9) Any change in the type of emission;
    (10) Any change in authorized effective radiated power in excess of 3 dB (a 2-to-1
ratio);
    (11) Substitution of equipment having different frequency tolerance.
(e) When the name of the licensee is changed (without changes in the ownership, control, or
corporate structure), or when the mailing address is changed (without changing the authorized
location of the fixed station) a formal application for modification of license is not required.
However, the licensee must notify the Commission within thirty days of the effective date of
these changes. The notice, which may be in letter form, must contain the name and address of
the licensee as they appear in the Commission's records, the new name or address, the call
signs and classes of all radio stations authorized to the licensee under this part and the radio
service in which each station is authorized. The notice must be sent to the Federal
Communications Commission, Gettysburg, PA 17325 and a copy must be maintained with the
license of each station until a new license is issued.
 101.59  Processing of applications for facility minor modifications.
(a) Unless an applicant is notified to the contrary by the Commission, as of the twenty-first day
following the date of public notice, any application that meets the requirements of paragraph
(b) of this section and proposes only the change specified in paragraph (c) of this section will
be deemed to have been authorized by the Commission.
(b) An application may be considered under the procedures of this section only if:
    (1) It is in the Point-to-Point Microwave Radio, Local Television Transmission, or
Digital Electronic Message Service;
    (2) The cumulative effect of all such applications made within any 60 days period

accordance with  101.103(d) or, in the Digital Electronic Message Services, a copy of the
application has been served on those who also were served under  101.509.
(c) The modifications that may be authorized under the procedures of this section are:
    (1) Changes in a transmitter and existing transmitter operating characteristics, or
protective configuration of transmitter, provided that:
    (i) In all radio services other than Digital Electronic Message Service, any
increase in transmitter output power is less than three dB over the previously authorized output
power; and in Digital Electronic Message Service, any increase in transmitter output power is
one and one-half dB or less over the previously authorized output power;
    (ii) The necessary bandwidth is not increased beyond the previously authorized
bandwidth;
    (2) Changes in the center line height of an antenna, provided that:
    (i) In all radio services except the Digital Electronic Message Service, any

height;
    (ii) In Digital Electronic Message Service, any increase in antenna height is
less than 3.0 meters (10 feet) above the previously authorized height; and
    (iii) The overall height of the antenna structure is not increased as a result of
the antenna extending above the height of the previously authorized structure, except when the
new height of the antenna structure is 6.1 meters (20 feet) or less (above ground or man-made
structure, as appropriate) after the change is made.
    (3) Change in the geographical coordinates of a transmit station, receive station or
passive facility by five (5) seconds or less of latitude, longitude or both, provided that when
notice to the FAA of proposed construction is required by Part 17 of the rules for antenna
structure at the previously authorized coordinates (or will be required at the new location) the
applicant must comply with the provisions of  101.21(a).
(d) Upon grant of an application under the procedure of this section and at such time that
construction begins, the applicant must keep a complete copy of the application (including the
filing date) with the station license if construction begins prior to receipt of the authorization.
 101.61  Certain modifications not requiring prior authorization.
(a) Equipment in an authorized radio station may be replaced without prior authorization or
notification if the replacement equipment is equivalent to the replaced equipment.
(b) Licensees of fixed stations in the Point-to-Point Microwave Radio, Local Television
Transmission, or Digital Electronic Message, may make the facility changes listed in paragraph
(c) of this section without obtaining prior Commission authorization, if:
    (1) Frequency coordination procedures, as necessary, are complied with in
accordance with  101.103(d) or, in the Digital Electronic Message Services, a copy of the
notification described in (b)(3) is served on those who were served under  101.509, and
    (2) The cumulative effect of all facility changes made within any 60 day period does
not exceed the appropriate values prescribed by paragraph (c) of this section, and
    (3) The Commission is notified of changes made to facilities by the submission of a
completed FCC Form 494 within thirty days after the changes are made.
(c) Modifications that may be made without prior authorization under paragraph (b) of this
section are:
    (1) Change or modification of a transmitter, when:
    (i) The replacement or modified transmitter is type-accepted (or type-notified)
for use under this Part and is installed without modification from the type-accepted (or type
notified) configuration;
    (ii) The type of modulation is not changed;
    (iii) The frequency stability is equal to or better than the previously authorized
frequency stability; and
    (iv) The necessary bandwidth and the output power do not exceed the
previously authorized values.
    (2) Addition or deletion of a transmitter for protection without changing the authorized
power output (e.g. hot standby transmitters);
    (3) Change to an antenna (other than any change involving a periscope antenna
system), when:
    (i) For the Point-to-Point Microwave Radio and Local Television Transmission
Services, the new antenna conforms to the requirements of  101.115 and has essentially the
same or better radiation characteristics than the previously authorized antenna;
    (ii) For the Digital Electronic Message Service, the new antenna conforms with
 101.517 and the gain of the new antenna does not exceed that of the previously authorized
antenna by more than one dB in any direction.
    (4) Any technical changes that would decrease the effective radiated power.
    (5) Change to the height of an antenna, when:
    (i) The new height (measured at the center-of-radiation) is within +/- 1.5 meters
(5 feet) of the previously authorized height; and
    (ii) The overall height of the antenna structure is not increased as a result of
the antenna extending above the height of the previously authorized structure, except when the
new height of the antenna structure is 6.1 meters (20 feet) or less (above ground or man-made

    (6) Decreases in the overall height of an antenna structure, provided that, when
notice to the FAA of proposed construction was required by Part 17 of the Rules for the
antenna structure at the previously authorized height, the applicant must comply with the
provisions of  101.21(a).
    (7) Changes in the azimuth of the center of the main lobe of radiation of a
point-to-point station's antenna by a maximum of one degree.
    (8) Changes to the transmission line and other devices between the transmitter and
the antenna when the effective radiated power of the station is not increased by more than one
dB.
(d) Licensees may notify the Commission of permissible changes or correct erroneous
information on a license not involving a major change (i.e., a change that would be classified
as a major amendment as defined by  101.29) without obtaining prior Commission approval
by filing FCC Form 494.
 101.63  Period of construction; certification of completion of construction.
(a) Except as provided in paragraphs (b) and (f) of this section, each station authorized under
this part must be in operation within 12 months from the initial date of grant.  Modification of an
operational station must be completed within 12 months of the date of grant of the applicable
modification request.
(b)  Each station licensed on point-to-multipoint frequencies in the 10.6 GHz and 18 GHz
bands must be in operation within 18 months of the initial date of grant.  Modification of an
operational station must be completed within 18 months of the initial date of grant of the
applicable modification request.
(c) Failure to timely begin operation means the authorization cancels automatically and must be
returned to the Commission.  Neither the capability for transmission nor the transmission of color bars
or similar test signals constitutes operation.  For purposes of this rule, the transmission of operational
traffic, not test or maintenance signals, is necessary and sufficient to constitute operation.
(d)  The frequencies associated with all point-to-multipoint authorizations which have cancelled
automatically or otherwise been recovered by the Commission will again be made available for
reassignment on a date and under terms set forth by Public Notice.
(e)  Requests for extension of time to be in operation may be granted upon a showing of good cause,
setting forth in detail the applicant's reasons for failure to have the facility operating in the prescribed
period.  Such requests must be submitted no later than 30 days prior to the end of the prescribed
period to the Federal Communications Commission, Gettysburg, PA 17325-7245.
(f) Construction of Common Carrier stations may not commence until the grant of a license, and must
be  completed by the date specified in the license as the termination date of the construction period.
Each licensee must file with the Commission a certification of completion of construction using FCC
Form 494A, certifying that the facilities as authorized have been completed and that the station is now
operational and ready to provide service to the public, and will remain operational during the license
period, unless the license is submitted for cancellation.
 101.65  Forfeiture and termination of station authorization.
(a) A common carrier license will be automatically forfeited in whole or in part without further notice to
the licensee upon:
    (1) The expiration of the construction period specified therein, or after such additional time as
may be authorized by the Commission, unless within 5 days after construction period date a certification
of completion of construction has been filed with the Commission pursuant to  101.63; or
    (2) The expiration of the license period specified therein, unless prior thereto an application
for renewal of such license has been filed with the Commission; or
    (3) The voluntary removal or alteration of the facilities, so as to render the station not
operational for a period of 30 days or more.
(b) A license forfeited in whole or in part under the provisions of paragraph (a)(1) or (a)(2) may be
reinstated if the Commission, in its  discretion, determines that reinstatement would best serve the
public  interest, convenience and necessity. Petitions for reinstatement filed  pursuant to this subsection
will be considered only if:
    (1) The petition is filed within 30 days of the expiration date set forth in paragraph (a)(1) or
(a)(2) of this section, whichever is applicable;
    (2) The petition explains the failure to timely file such notification or application as would have
prevented automatic forfeiture; and
    (3) The petition sets forth with specificity the procedures which have been established to
insure timely filings in the future.
(c) A special temporary authorization will automatically terminate upon the expiration date specified
therein, or upon failure to comply with any special terms or conditions set forth therein. Operation may
be extended beyond such termination date only after application and upon specific  authorization by the
Commission.
(d) If a station licensed under this part discontinues operation on a permanent basis, the licensee must
forward the station license to the Federal Communications Commission, Gettysburg, Pennsylvania
17325, for cancellation. For purposes of this section, any station which has not operated for one year or
more is considered to have been permanently discontinued.  See Section 101.305 for additional rules
regarding temporary and permanent discontinuation of service.
 101.67  License period.
(a) Except as provided in paragraph (e) of this Section, licenses for stations authorized under this Part
will be issued for a period not to exceed 10 years from date of grant.
(b)The expiration date of developmental licenses will be one year from the date of the grant thereof.
When a license is granted subsequent to the last  renewal date of the class of license involved, the
license will be issued only for the unexpired period of the current license term of such class.
(c) The Commission reserves the right to grant or renew station licenses in these services for a shorter
period of time than that generally prescribed for such stations if, in its judgment, public interest,
convenience, or necessity would be served by such action.
(d) Upon the expiration or termination of any station license, any related construction permit, which
bears a later expiration date, will be automatically terminated concurrently with the related station
license, unless it has been determined by the Commission that the public interest, convenience or
necessity would be served by continuing in effect said construction permit.
(e) Licenses for Local Television Transmission Service stations that are assigned frequencies allocated
to the broadcast services shall terminate simultaneously with the expiration of the authorization for the
broadcast station to which such service is rendered.
 101.69   Transition of the 2.11-2.13, and 2.16-2.18 GHz bands from  Common Carrier Fixed
Microwave Services and the 1.85-1.99, 2.13-2.15, and 2.18-2.20 GHz bands from Private Operational
Fixed Microwave Service to emerging technologies.
(a) Licensees proposing to implement services using emerging technologies (ET Licensees) may
negotiate with Common Carrier and Private Operational Fixed Microwave Service licensees (Existing
Licensees)  in these bands for the purpose of agreeing to terms under which the Existing Licensees
would relocate their operations to other fixed microwave bands or to other media, or alternatively, would
accept a sharing arrangement with the ET Licensee that may result in an otherwise impermissible level
of interference to the existing licensee's operations.  ET Licensees may also negotiate agreements for
relocation of the Existing Licensees' facilities within the 2 GHz band in which all interested parties agree
to the relocation of the Existing Licensee's facilities elsewhere within these bands.  "All interested
parties" includes the incumbent licensee, the emerging technology provider or representative requesting
and paying for the relocation, and any emerging technology licensee of the spectrum to which the
incumbent's facilities are to be relocated.
(b) Common Carrier and Private Operational Fixed Microwave licensees, with the exception of public
safety facilities defined in paragraph (f) of this section, in bands allocated for licensed emerging
technology services will maintain primary status in these bands until two years after the Commission
commences acceptance of applications for an emerging technology services (two-year voluntary
negotiation period), and until one year after an emerging technology service licensee initiates
negotiations for relocation of the fixed microwave licensee's operations (one-year mandatory negotiation
period) or, in bands allocated for unlicensed emerging technology services, until one year after an
emerging technology unlicensed equipment supplier or representative initiates negotiations for relocation
of the fixed microwave licensee's operations (one-year mandatory  negotiation period).  When it is
necessary for an emerging technology provider or representative of unlicensed device manufacturers to
negotiate with a fixed microwave licensee with operations in spectrum adjacent to that of the emerging
technology provider, the transition schedule of the entity requesting the move will apply.  Public safety
facilities defined in paragraph (f) of this section will maintain primary status in these bands until four
years after the Commission commences acceptance of applications for an emerging technology service
(four-year voluntary negotiation period), and until one year after an emerging technology service
licensee or an emerging technology unlicensed equipment supplier or representative initiates
negotiations for relocation of the fixed microwave licensee's operations (one-year mandatory negotiation
period).
(c)  The Commission will amend the operation license of the fixed microwave operator to secondary
status only if the following requirements are met:
    (1) The service applicant, provider, licensee, or representative using an emerging technology
guarantees payment of all relocation costs, including all engineering, equipment, site and FCC fees, as
well as any reasonable, additional costs that the relocated fixed microwave licensee might incur as a
result of operation in another fixed microwave band or migration to another medium;
    (2)  The emerging technology service entity completes all activities necessary for
implementing the replacement facilities, including engineering and cost analysis of the relocation
procedure and, if radio facilities are used, identifying and obtaining, on the incumbents' behalf, new
microwave frequencies and frequency coordination; and
    (3) The emerging technology service entity builds the replacement system and tests it for
comparability with the existing 2 GHz system.
(d)  The 2 GHz microwave licensee is not required to relocate until the alternative facilities are available
to it for a reasonable time to make adjustments, determine comparability, and ensure a seamless
handoff.
(e)  If within one year after the relocation to new facilities the 2 GHz microwave licensee demonstrates
that the new facilities are not comparable to the former facilities, the emerging technology service entity
must remedy the defects or pay to relocate the microwave licensee back to its former or equivalent 2
GHz frequencies.
(f) Public safety facilities subject to the four-year voluntary and one-year mandatory negotiation periods,
are those that the majority of communications carried are used for police, fire, or emergency medical
services operations involving safety of life and property.  The facilities within this exception are those
facilities currently licensed on a primary basis pursuant to the eligibility requirements of   90.19, Police
Radio Service;   90.21, Fire Radio Service;   90.27 Emergency Medical Radio Service; and Subpart C
of Part 90, Special Emergency Radio Services.  Licensees of other Part 101 facilities licensed on a
primary basis under the eligibility requirements of Part 90, Subparts B and C, are permitted to request
similar treatment upon demonstrating that the majority of the communications carried on those facilities
are used for operations involving safety of life and property.

 * - Applications for frequencies in the 932.5-935/941.5-944 MHz bands may be filed initially
during a one-week period to be announced by public notice.  After these applications have been
processed, the Commission will announce by public notice a filing date for remaining frequencies.  From
this filing date forward, applications will be processed on a daily first-come, first-served basis.
 101.103 Frequency coordination procedures.
(a)  Assignment of frequencies will be made only in such a manner as to facilitate the rendition of
communication service on an interference-free basis in each service area. Unless otherwise indicated,
each frequency available for use by stations in these services will be assigned exclusively to a single
applicant in any service area. All applicants for, and licensees of, stations in these services must
cooperate in the selection and use of the frequencies assigned in order to minimize interference and
thereby obtain the most effective use of the authorized facilities. In the event harmful interference
occurs or appears likely to occur between two or more radio systems and such interference cannot be
resolved between the licensees thereof, the Commission may specify a time sharing arrangement for
the stations involved or may, after notice and opportunity for hearing, require the licensees to make
such changes in operating techniques or equipment as it may deem necessary to avoid such
interference.
(b) The provisions of this section do not apply to operations in the band 31.0 to 31.3 GHz. Operations in
this band are unprotected and subject to harmful interference from other licensed operations in this
band.
(c) Frequency diversity transmission will not be authorized in these services in the absence of a factual
showing that the required communications cannot practically be achieved by other means. Where
frequency diversity is deemed to be justified on a protection channel basis, it will be limited to one
protection channel for the bands 3,700-4,200, 5925-6425, and 6525-6875 MHz, and a ratio of one
protection channel for three working channels for the bands 10,550-10,680 and 10,700-11,700 MHz. In
the bands 3,700-4,200, 5,925-6,425, and 6525-6875 MHz, no frequency diversity protection channel will
be authorized unless there is a minimum of three working channels, except that where a substantial
showing is made that a total of three working channels will be required within three years, a protection
channel may be authorized simultaneously with the first working channel. A protection channel
authorized under such exception will be subject to termination if applications for the third working
channel are not filed within three years of the grant date of the applications for the first working channel.
Where equipment employing digital modulation techniques with cross-polarized operation on the same
frequency is used, the protection channel authorized under the above conditions may be considered to
consist of both polarizations of the protection frequency where such is shown to be necessary.
(d) Frequency coordination. When required, the following frequency usage coordination procedures will
apply.
 (1) General requirements. Proposed frequency usage must be prior coordinated with existing
users in the area, and other applicants with previously filed applications, whose facilities could affect or
be affected by the new proposal in terms of frequency interference on active channels, applied-for
channels, or channels coordinated for future growth. Coordination must be completed prior to filing an
application for regular authorization, or an amendment to a pending application, or a modification to a
license. In coordinating frequency usage with stations in the fixed satellite service, applicants must also
comply with the requirements of Sec. 101.713(c) and (d). In engineering a system or modification
thereto, the applicant must, by appropriate studies and analyses, select sites, transmitters, antennas
and frequencies that will avoid interference in excess of permissible levels to other users. All applicants
and licensees must cooperate fully and make reasonable efforts to resolve technical problems and
conflicts that may inhibit the most effective and efficient use of the radio spectrum; however, the party
being coordinated with is not obligated to suggest changes or re-engineer a proposal in cases involving
conflicts.  Applicants should make every reasonable effort to avoid blocking the growth of systems as
prior coordinated. The applicant must identify in the application all entities with which the technical
proposal was coordinated. In the event that technical problems are not resolved, an explanation must
be submitted with the application. Where technical problems are resolved by an agreement or operating
arrangement between the parties that would require special procedures be taken to reduce the
likelihood of interference in excess of permissible levels (such as the use of artificial site shielding)or
would result in a reduction of quality or capacity of either system, the details thereof may be contained
in the application.
 (2) Coordination procedure guidelines are as follows:
 (i) Coordination involves two separate elements: notification and response.  Both or
either may be oral or in written form. To be acceptable for filing, all applications and major technical
amendments must certify that coordination, including response, has been completed. The names of the
users with coordinated proposals, applicants, permittees, and licensees with which coordination was
accomplished must be specified.
 (ii) Notification must include relevant technical details of the proposal.  At minimum, this
should include, as applicable, the following:
  Applicant's name.
  Transmitting station name.
  Transmitting station coordinates.
  Frequencies and polarizations to be added or changed.
  Transmitting equipment type, its stability, actual output power, emission  designator, and type of
 modulation (loading).
  Transmitting antenna type and model and, if required, a radiation pattern  provided or certified by the
 manufacturer.
  Transmitting antenna center line height above ground level and ground  elevation above mean sea
 level.
  Receiving station name.
  Receiving station coordinates.
  Receiving antenna type, model, gain, and, if required, a radiation pattern  provided by the
 manufacturer.
  Receiving antenna center line height above ground level and ground elevation  above mean sea level.
  Forward and reverse path azimuth and distance.
            (iii) For transmitters employing digital modulation techniques, the notification should
clearly identify the type of modulation. Upon request, additional details of the operating characteristics of
the equipment must also be furnished.
 (iv) Response to notification should be made as quickly as possible, even if no technical
problems are anticipated. Any response to notification indicating potential interference must specify the
technical details and must be provided to the applicant, in writing, within the 30-day notification period.
Every reasonable effort should be made by all applicants, permittees and licensees to eliminate all
problems and conflicts. If no response to notification is received within 30 days, the applicant will be
deemed to have made reasonable efforts to coordinate and may file its application without a response.
            (v) The 30-day notification period is calculated from the date of receipt by the applicant,
permittee, or licensee being notified. If notification is by mail, this date may be ascertained by:
 (A) The return receipt on certified mail,
       (B) The enclosure of a card to be dated and returned by the recipient, or (C) A conservative
estimate of the time required for the mail to reach its destination.
In the latter case, the estimated date when the 30-day period would expire should be stated in the
notification.
 (vi)  An expedited prior coordination period (less than 30 days) may be requested when
deemed necessary by a notifying carrier.  The coordination notice should be identified as "expedited"
and the requested response date should be clearly indicated.  However, circumstances preventing a
timely response from the receiving carrier should be accommodated accordingly.  It is the responsibility
of the notifying carrier to receive written concurrence (or verbal, with written to follow) from affected
parties or their coordination representatives.
            (vii)  All technical problems that come to light during coordination must be resolved
unless a statement is included with the application to the effect that the applicant is unable or unwilling
to resolve the conflict and briefly the reason therefor.
            (viii) Where a number of technical changes become necessary for a system during the
course of coordination, an attempt should be made to minimize the number of separate notifications for
these changes. Where the changes are incorporated into a completely revised notice, the items that
were changed from the previous notice should be identified. When changes are not numerous or
complex, the carrier receiving the changed notification should make an effort to respond in less than 30
days. When the notifying carrier believes a shorter response time is reasonable and appropriate, it may
be helpful for that carrier to so indicate in the notice and perhaps suggest a response date.
            (ix) If, after coordination is successfully completed, it is determined that a  subsequent
change could have no impact on some carriers receiving the original notification, these carriers must be
notified of the change and of the coordinator's opinion that no response is required.
            (x) Applicants, permittees and licensees should supply to all other applicants, permittees
and licensees within their areas of operations, the name, address and telephone number of their
coordination representatives. Upon request from coordinating applicants, permittees and licensees, data
and information concerning existing or proposed facilities and future growth plans in the area of interest
should be furnished unless such request is unreasonable or would impose a significant burden in
compilation.
            (xi) Carriers should keep other carriers with whom they are coordinating advised of
changes in plans for facilities previously coordinated. If applications have not been filed 6 months after
coordination was initiated, carriers may assume that such frequency use is no longer desired unless a
second notification has been received within 10 days of the end of the 6 month period. Renewal
notifications are to be sent to all originally notified parties, even if coordination has not been
successfully completed with those parties.
 (xii) Any frequency reserved by a licensee for future use in the bands subject to this Part
must, upon a showing by another licensee that it requires an additional frequency and cannot
coordinate one that is not reserved for future use, file for the frequency within six (6) months after
receiving such a showing or release the frequency for use by the requesting licensee.
(e) Where frequency conflicts arise between co-pending applications in the Point-to-Point Microwave
Radio and Local Television Transmission Services, it is the obligation of the later filing applicant to
amend his application to remove the conflict, unless it can make a showing that the conflict cannot be
reasonably eliminated. Where a frequency conflict is not resolved and no showing is submitted as to
why the conflict cannot be resolved, the Commission may grant the first filed application and dismiss
the later filed application(s) after giving the later filing applicant(s) 30 days to respond to the proposed
action.
(f) When the proposed facilities are to be operated in the band 12,500-12,700 MHz, applications must
also follow the procedures in  101.713  of this Part and the technical standards and requirements of
Part 25 of this Chapter as regards licensees in the Communication-Satellite Service.
 101.105 Interference protection criteria.
(a) The interference protection criteria for fixed stations subject to this Part are as follows:
 (1) To long-haul analog systems, employing frequency modulated radio and frequency division
multiplexing to provide multiple voice channels, the allowable interference level per exposure:
 (i) Due to co-channel sideband-to-sideband interference must not exceed 5 pwpO
(Picowatts of absolute noise power psophometrically weighted (pwpO), appearing in an equivalent voice
band channel of 300-3400 Hz).
       (ii) Due to co-channel carrier-beat interference must not exceed 50 pwpO.
       (2) To short-haul analog systems employing frequency modulated radio and frequency division
multiplexing to provide multiple voice channels, the allowable interference level per exposure:
 (i) Due to co-channel sideband-to-sideband interference must not exceed 25 pwpO
except in the 952-960 MHz band interference into single link fixed relay and control stations must not
exceed 250 pwpO per exposure.
            (ii) Due to co-channel carrier-beat interference must not exceed 50 pwpO except in the
952-960 MHz band interference into single link fixed relay and control stations must not exceed 1000
pwpO per exposure.
       (3) FM-TV. In analog systems employing frequency modulated radio that is modulated by a
standard, television (visual) signal, the allowable interference level per exposure may not exceed the
levels which would apply to a long-haul or short-haul FM-FDM systems, as outlined in paragraphs (b)(1)
and (2) of this section, having a 600-1200 voice channel capacity.
(b) In addition to the requirements of paragraph (a) of this Section the adjacent channel interference
protection criteria to be afforded, regardless of system length, or type of modulation, multiplexing, or
frequency band, must be such that the interfering signal does not produce more than 1.0 dB
degradation of the practical threshold of the protected receiver.
(c) Applying the Criteria.
 (1)  Guidelines for applying the interference protection criteria for fixed stations subject to this
Part are specified in TIA Telecommunications Systems Bulletin TSB 10, "Interference Criteria for
Microwave Systems" (TSB 10).  Other procedures that follow generally acceptable good engineering
practices are also acceptable to the Commission.
 (2)  If TSB 10 guidelines cannot be used, the following interference protection criteria may be
used by calculating the ratio in dB between the desired (carrier signal) and the undesired (interfering)
signal (C/I ratio) appearing at the input to the receiver under investigation (victim receiver):
 (i) Except as provided in  101.605 of this Part, where the applicants proposed facilities are of a
type not included in paragraphs (a) and (b) of this section or where the development of the carrier-to-
interference (C/I) ratio is not covered by generally acceptable procedures, or where the applicant does
not wish to develop the carrier-to-interference ratio, the applicant must, in the absence of criteria or a
developed C/I ration, employ the following C/I protection ratios:
 Co-channel interference:  both sideband and carrier-beat, applicable to all bands; the existing or
previously authorized system must be afforded a carrier to interfering signal protection ratio of at least
90 dB except in the 952-960 MHz band where it must be 75 dB.
      Adjacent channel interference:  applicable to all bands; the existing or previously authorized system
must be afforded a carrier to interfering signal protection ratio of at least 56 dB.
       (3) Applicants for frequencies listed in Sec. 101.605(a)(1) must make the following showings
that protection criteria have been met over the entire service area of existing systems. Such showings
may be made by the applicant or may be satisfied by a statement from a Frequency Advisory
Committee. For frequencies available to more than one service, the Frequency Advisory Committee
must affirmatively show that coordination with similar Committees for the other services has been
accomplished.
 (i) For multiple address stations in the 928-929/952-960 MHz bands, a statement that
the proposed system complies with the following co-channel separations from all existing stations and
pending applications:
                       Fixed-to-fixed    145 km (90 miles)
                       Fixed-to-mobile   113 km (70 miles)
                       Mobile-to-mobile  81 km (50 miles)
Multiple address systems employing only remote stations will be treated as mobile for the purposes of
determining the appropriate separation. For mobile operation, the mileage is measured from the
reference point specified on the license application.
 (ii) For multiple address stations in the 932-932.5/941-941.5 MHz bands, a statement
that the proposed system complies with the following co-channel separation from all existing stations
and pending applications:
                        Fixed-to-fixed  113 Km (70 miles)
            (iii) In cases where the geographic separation standard in paragraphs (c)(4)(i) and
(c)(4)(ii) of this section are not followed, an engineering analysis will be submitted to show the
coordination of the proposed assignment with existing systems located closer than those standards. The
engineering analyses will include:
 (A) Specification of the interference criteria and system parameters used in the interference
study.
       (B) Nominal service areas of each system included in the interference analysis.
 (C) Modified service areas resulting from the proposed system. The propagation models used to
establish the service boundary limits must be specified and any special terrain features considered in
computing the interference impact should be described.
 (D) A statement that all parties affected have agreed to the engineering analysis and will accept
the calculated levels of interference.
 (5) Multiple address frequencies in the 956 MHz band may be assigned for use by mobile
master stations on a primary basis. Multiple address frequencies in the 952 MHz band may be assigned
for use by mobile master stations on a case-by-case basis. Mobile operation in the 952 MHz band will
be on a secondary basis to fixed operations.
 (6) Each application for new or modified nodal station on channels numbered 4A, 4B, 7, 9, and
19/20 in the 10.6 GHz band and all point-to-multipoint channels in the 18 GHz band must demonstrate
that all existing co-channel stations are at least 56 kilometers from the proposed nodal station site.
Applicants for these channels must certify that all licensees and applicants for stations on the adjacent
channels within 56 kilometers of the proposed nodal station have been notified of the proposed station
and do not object. Alternatively, or if one of the affected adjacent channel interests does object, the
applicant may show that all affected adjacent channel parties are provided a C/I protection ratio of 0 dB.
An applicants proposing to operate at an AAT greater than 91 meters must reduce its EIRP in
accordance with the following table; however, in no case may EIRP exceed 70 dBm on the 10.6 GHz
channels.

 100 and below         85
 (7) Each application for new or modified nodal station on channels numbered 21, 22, 23, and 24
in the 10.6 GHz band must include an analysis of the potential for harmful interference to all other
licensed and previously applied for co-channel and adjacent channel station located within 80
kilometers of the location of the proposed station. The criteria contained in  101.103(d)(3) must be
used in this analysis. Applicants must certify that copies of this analysis have been served on all parties
which might reasonably be expected to receive interference above the levels set out in  101.103(d)(3)
within 5 days of the date the subject application is filed with the Commission.
(d) An applicant filing for a modification of an existing station under the provisions of  101.31 need not
perform the interference protection analyses required by this section if the only modifications made to
the station are one or more of the following:
 (1) Substitution of transmitting equipment having equal or tighter frequency tolerance.
 (2) Any decrease in antenna primary lobe beamwidth which is accompanied by a corresponding
decrease in antenna input power so as to not increase the effective radiated power in excess of 3dB (a
2 to 1 ratio).
 (3) Any decrease in antenna height or transmitter output power.
(e) Effective August 1, 1985, when a fixed station that conforms to the technical standards of this
subpart (or, in the case of the 12,200-12,700 MHz band, a direct broadcast satellite station) receives or
will receive interference in excess of the levels specified in this section as a result of an existing
licensee's use of non-conforming equipment authorized between July 20, 1961 and July 1, 1976, and
the interference would not result if the interfering station's equipment complied with the current technical
standards, the licensee of the non-conforming station must take whatever steps are necessary to
correct the situation up to the point of installing equipment which fully conforms to the technical
standards of this subpart. In such cases, if the engineering analysis demonstrates that (1) the
conforming station would receive interference from a non-conforming station in excess of the levels
specified in this section and (2) the interference would be eliminated if the non-conforming equipment
were replaced with equipment which complies with the standards of this subpart, the licensee (or
prospective licensee) of the station which would receive interference must provide written notice of the
potential interference to both the non-conforming licensee and the Commission's office in Gettysburg,
PA. The non-conforming licensee must make all required equipment changes within 180 days from the
date of official Commission notice informing the licensee that it must upgrade its equipment, unless an
alternative solution has been agreed to by all parties involved in the interference situation. If a
non-conforming licensee fails to make all required changes within the specified period of time, the
Commission may require the licensee to suspend operation until the changes are completed.
 101.107  Frequency tolerance.
(a) The carrier frequency of each transmitter authorized in these services  must be maintained within
the following percentage of the reference frequency except as otherwise provided in paragraph (b) of
this section or in the applicable subpart of this part (unless otherwise specified in the instrument of
station authorization the reference frequency will be deemed to be the assigned frequency):

     /1/ Applicable only to common carrier LTTS stations.  Beginning Aug. 9, 1975, this tolerance will
govern the marketing of LTTS equipment and the issuance of all such authorizations for new radio
equipment. Until that date new equipment may be authorized with a frequency tolerance of .03 percent
in the frequency range 2,200 to 10,500 MHz and .05 percent in the range 10,500 MHz to 12,200 MHz,
and equipment so authorized may continue to be used for its life provided that it does not cause
interference to the operation of any other licensee.
     /2/ Equipment authorized to be operated on frequencies between 890 and 940 MHz as of Oct.
15, 1956, must maintain a frequency tolerance within 0.03 percent subject to the condition that no
harmful interference is caused to any other radio station.
     /3/ See Subpart G for the stability requirements for transmitters used in the Digital Electronic
Message Service.
     /4/ Existing type accepted equipment with a frequency tolerance of +/-0.03% may be marketed
until December 1, 1988. Equipment installed and operated prior to December 1, 1988 may continue to
operate after that date with a minimum frequency tolerance of +/-0.03%. However, the replacement of
equipment requires that the +/-0.003% tolerance be met.
     /5/  For remote stations with 12.5 kHz bandwidth, the tolerance is  0.00015%.
     /6/ Applicable to private operational fixed only.  For exceptions see  101.605.
     /7/ For private operational fixed point-to-point systems, with a channel greater than or equal to
50 kHz bandwidth,  0.0005%; for multiple address master stations, regardless of bandwidth,
0.00015%; for multiple address remote stations with 12.5 kHz bandwidths,  0.00015%; for multiple
address remote stations with channels greater than 12.5 kHz bandwidth,  0.0005%.
(b) Heterodyne microwave radio systems may be authorized a somewhat less restrictive frequency
tolerance (up to .01 percent) to compensate for  frequency shift caused by numerous repeaters between
base band signal  insertion. Where such relaxation is sought, applicant must provide all   calculations
and indicate the desired tolerance over each path. In such instances the radio transmitters used must
individually be capable of complying with the tolerance specified in paragraph (a) of this section.
(c) As an additional requirement in any band where the Commission makes assignments according to a
specified channel plan, provisions must be made to prevent the emission included within the occupied
bandwidth from radiating outside the assigned channel at a level greater than that specified in
 101.111.
 101.109 Bandwidth.
(a) Each authorization issued pursuant to these rules will show, as the emission designator, a symbol
representing the class of emission which must be prefixed by a number specifying the necessary
bandwidth. This figure does not necessarily indicate the bandwidth actually occupied by the emission at
any instant. In those cases where Part 2 of this chapter does not provide a formula for the computation
of the necessary bandwidth, the occupied bandwidth may be used in the emission designator.
(b) Stations in this service will be authorized any type of emission, method of modulation, and
transmission characteristic, consistent with efficient use of the spectrum and good engineering practice,
except that Type B, damped-wave emission will not be authorized.
 101.111  Emission limitations.
(a) The mean power of emissions must be attenuated below the mean output power of the transmitter in
accordance with the following schedule:
     (1) When using transmissions other than those employing digital modulation techniques:
     (i) On any frequency removed from the assigned frequency by more than 50 percent up
to and including 100 percent of the authorized bandwidth: At least 25 decibels;
     (ii) On any frequency removed from the assigned frequency by more than 100 percent
up to and including 250 percent of the authorized bandwidth: At least 35 decibels;
     (iii) On any frequency removed from the assigned frequency by more than 250 percent
of the authorized bandwidth: At least 43+10 Log10 (mean output power in watts) decibels, or 80
decibels, whichever is the lesser attenuation.
     (2) When using transmissions employing digital modulation techniques (see  101.141(b)) in
situations not covered in this section:
     (i) For operating frequencies below 15 GHz, in any 4 kHz band, the center frequency of
which is removed from the assigned frequency by more than 50 percent up to and including 250
percent of the authorized bandwidth: As specified by the following equation but in no event less than 50
decibels.
 A=35+0.8(P-50)+10 Log10B. (Attenuation greater than 80 decibels is not required.)
where:
A=Attenuation (in decibels) below the mean output power level.
P=Percent removed from the carrier frequency.
B=Authorized bandwidth in MHz.
     (ii) For operating frequencies above 15 GHz, in any 1 MHz band, the center frequency
of which is removed from the assigned frequency by more than 50 percent up to and including 250
percent of the authorized bandwidth: As specified by the following equation but in no event less than 11
decibels.
A=11+0.4(P-50)+10 Log10B. (Attenuation greater than 56 decibels is not
required.)
     (iii) In any 4 kHz band, the center frequency of which is removed from the assigned
frequency by more than 250 percent of the authorized bandwidth: At least 43+10 Log10 (mean output
power in watts) decibels, or 80 decibels, whichever is the lesser attenuation.
     (3) For Digital Termination System channels used in the Digital Electronic Message Service
(DEMS) operating in the 10,550-10,680 MHz band:
     (i) In any 4 kHz band, the center frequency of which is removed from the edge of the
DEMS channel by up to and including 1.125 times the DEMS subchannel bandwidth: As specified by
the following equation may in no event be less than 50+10 log10 N decibels.
A=50+0.0333 (F-0.5B)+10 log10 N decibels
Where:
A=Attenuation (in decibels) below means output power level contained within the DEMS channel for a
given polarization.
B=Bandwidth of DEMS channel (in kHz).

station and system maintenance.
 101.113  Transmitter power limitations.
(a) On any authorized frequency, the average power delivered to an antenna in this service must be the
minimum amount of power necessary to carry out the communications desired.  Application of this
principle includes, but is not be limited to, requiring a licensee who replaces one or more of its antennas
with larger antennas to reduce its antenna input power by an amount appropriate to compensate for the
increased primary lobe gain of the replacement antenna(s).  In no event shall the average equivalent
isotropically radiated power (EIRP), as referenced to an isotropic radiator, exceed the values specified
below.  In cases of harmful interference, the Commission may, after notice and opportunity for hearing,
order a change in the effective radiated power of this station.  Further, the output power of a transmitter
on any authorized frequency in this service may not exceed the following:

              --------------------------------------
           (1) For multiple address operations,see  101.605(a)(1)(v).  When an omnidirectional antenna is
authorized in the 2150-2160 MHz band, the maximum power is 60 dBm. Remote alarm units that are part
of a multiple address central station protection system are authorized a maximum of 2 watts.
 (2) The power delivered to the antenna is limited to -3 dBW.
 (3) Output power of a DEMS System nodal transmitter may not exceed 0.5 watts per 250 KHz.
The output power of a DEMS System user transmitter may not exceed 0.04 watts per 250 KHz.  The
transmitter power in terms of the watts specified is the peak envelope power of the emission measured at
the associated antenna input power.  The operating power may not exceed the authorized power by more
than 10 percent of the authorized power in watts at any time.
 (4) Also, see  101.145 and 101.605.
 101.115  Directional antennas.
(a) Unless otherwise authorized upon specific request by the applicant,  each station authorized under the
rules of this part must employ a directional antenna adjusted with the center of the major lobe of radiation
in the horizontal plane directed toward the receiving station with which it communicates: provided,
however, where a station communicates with more than one point, a multi- or omni-directional antenna
may be authorized if necessary. New Periscope antenna systems will not, under ordinary circumstances,
be authorized.
(b) Stations operating below 2500 MHz that are required to use directional antennas must  employ
antennas meeting the standards indicated below.
(Maximum beamwidth is for the major lobe of radiation at the half power
points. Suppression is the minimum attenuation required for any secondary
lobe signal and is referenced to the maximum signal in the main lobe.)

(c) Fixed stations (other than temporary fixed stations and DEMS nodal stations) operating at 2,500 MHz
or higher must employ transmitting and receiving antennas (excluding second receiving antennas for
operations such as space diversity) meeting the appropriate performance Standard A indicated below,
except that in areas not subjected to frequency congestion antennas meeting performance Standard B
may be used subject to the requirements set forth in paragraph (d) of this Section.

 (1)  DEMS User Station antennas in this band must meet  performance Standard B and have a
minimum antenna gain of 34 dBi.  The maximum beamwidth requirement does not apply to DEMS User
Stations.  DEMS Nodal Stations need not comply with these standards.
 (2)  The minimum front-to-back ratio must be 38 dBi.
 (3)  Mobile, except aeronautical mobile, stations need not comply with these standards.
 (4)  Except for antennas between 140 and 180 authorized or pending on January 1, 1989, in the
band 10,550 to 10,565 MHz for which minimum radiation to suppression to angle (in degrees) from
centerline of main beam is 36 decibels.
 (5)  These antenna standards apply to all point-to-point stations authorized after June 1, 1997.
Existing licensees and pending applicants on that date are grandfathered and need not comply with these
standards.
 (6)  These antenna standards apply to all point-to-point stations authorized on or before June 1,
1997.
 (7)  These antenna standards apply only to DEMS User Stations licensed, in operation, or applied
for prior to July 15, 1993.
 (8)  Except for Multiple Address System frequencies listed in where omnidirectional antennas may
be used.
 (9)  Antennas used at outlying stations as part of a central protection alarm system need conform
to only the following 2 standards:  (1) The minimum on-beam forward gain must be at least 10 dBi, and (2)
the minimum front-to-back ratio must be at least 20 dB.
 (10)  Except as provided in Section 101.605.
 NOTE:  Stations must employ an antenna that meets the performance standards for Category A,
except that in areas not subject to frequency congestion, antennas meeting standards for Category B may
be employed.  Note, however, that the Commission may require the use of high performance antennas
where interference problems can be resolved by the use of such antennas.
(d) The Commission may require the replacement, prior to activation of the new facilities, at the licensee's
expense, of any antenna or periscope antenna system of a permanent fixed station operating at 2500
MHz or higher that does not meet performance Standard A specified in paragraph (c) of this Section,
upon a showing that said antenna causes or is likely to cause interference to (or receive interference
from) any other authorized or applied for station whereas a higher performance antenna is not likely to
involve such interference.  Antenna performance is expected to meet the standards of paragraph (c) of
this Section for parallel polarization.  For cases of potential interference, an antenna will not be
considered to meet Standard A unless the parallel polarization performance for the discrimination angle
involved meets the requirements, even if the cross-polarization performance controls the interference.
(e) In cases where passive reflectors are employed in conjunction with  transmitting antenna systems, the
foregoing paragraphs of this section also  will be applicable. However, in such instances, the center of the
major lobe of radiation from the antenna normally must be directed at the passive reflector, and the center
of the major lobe of radiation from the  passive reflector directed toward the receiving station with which it
communicates.
(f) New periscope antenna systems will be authorized for operation in private operational fixed stations
upon a certification that the radiation, in a horizontal plane, from an illuminating antenna and reflector
combination meets or exceeds the antenna standards of this section and, at locations where multiple
periscope antennas are employed, that the cross-coupling between periscope antennas is suppressed by
an amount equal to or greater than the radiation suppression specified in the standards for angles from
the main beam of 140-180 for the particular band and antenna category selected. In no event will
periscope antennas be authorized in frequency bands shared with common carriers.
(g) Periscope antennas used at an electric power facility plant area will be excluded from the
requirements of paragraphs (c) and (e) of this section on a case-by-case basis where technical
considerations preclude the use of other types of antenna systems.
(h) In the event harmful interference is caused to the operation of other stations, the Commission may,
after notice and opportunity for hearing, order changes to be made in the height, orientation, gain and
radiation pattern of the antenna system.
 101.117  Antenna polarization.
Stations operating in the radio services included in this part are not limited as to the type of polarization of
the radiated signal, provided, however, that in the event interference in excess of permissible levels is
caused to the operation of other stations the Commission may, after notice and opportunity for hearing,
order the licensee to change the polarization of the radiated signal. No change in polarization may be
made without prior authorization from the Commission.
 101.119  Simultaneous use of common antenna structures.
The simultaneous use of common antenna structures by more than one radio station, or by one or more
domestic public radio stations and one or more stations of any other class or service, may be authorized:
Provided, however, That each licensee or user of any such structure is responsible for maintaining the
structure, and for painting and illuminating the structure when obstruction marking is required by the
Commission. (See  101.21(d).)
 101.121  Marking of antenna structures.
No permittee or licensee who has been required to paint or light an antenna structure may discontinue the
required painting or lighting without having obtained prior written authorization therefor from the
Commission. (For complete regulations relative to antenna marking requirements, see Part 17 of
this chapter.)
 101.123  Quiet zones.
Quiet zones are those areas where it is necessary to restrict radiation so as to minimize possible impact
on the operations of radio astronomy or other facilities that are highly sensitive to radio frequency
interference.
(a) In order to minimize possible harmful interference at the National Radio Astronomy Observatory site
located at Green Bank, Pocohontas County, W. Va., and at the Naval Radio Research Observatory site at
Sugar Grove, Pendleton County, W. Va., any applicant for a station authorization other than
temporary-fixed seeking a station license for a new station or to modify an existing station in a manner
which would change either the frequency, power, antenna height or directivity, or location of such a
station within the area boarded by 3915' N. on the north, 7830' W. on the east, 3730' N. on the south,
and 8030' W. on the west must at the time of filing such application with the Commission, simultaneously
notify the Director, National Radio Astronomy Observatory, Post Office Box No. 2, Green Bank, W. Va.
24944, in writing, of the technical particulars of the proposed station.  Such notification must include the
geographical coordinates of the antenna, antenna height, antenna directivity if any, proposed frequency,
type of emission and power.  In addition, the applicant must indicate in his application to the Commission
the date notification was made to the Observatory.  After receipt of such applications, the Commission will
allow a period of twenty (20) days for comments or objections in response to the notifications indicated.  If
an objection to the proposed operation is received during the 20-day period from the National Radio
Astronomy Observatory for itself or on behalf of the Naval Radio Research Observatory, the Commission
will consider all aspects of the problem and take whatever action is deemed appropriate.
(b) Protection for Table Mountain Radio Receiving Zone, Boulder County, Colorado.  Applicants for a
station authorization to operate in the vicinity of Boulder County, Colorado under this part are advised to
give due consideration, prior to filing applications, to the need to protect the Table Mountain Radio
Receiving Zone from harmful interference.  These are the research laboratories of the Department of
Commerce, Boulder County, Colorado. To prevent degradation of the present ambient radio signal level
at the site, the Department of Commerce seeks to ensure that the field strengths of any radiated signals
(excluding reflected signals) received on this 1800 acre site (in the vicinity of coordinates 4007'50" N.
Latitude, 10514'40" W.  Longitude), resulting from new assignments or from the modification or relocation
of existing facilities do not exceed 1 mV/m in the authorized bandwidth of service.  (A field strength of 1
mV/m is equivalent to a power flux density of 85.8 dBW/M2 assuming a free-space characteristic
impedance of 376.7 ohms.)
(1) Advance consultation is recommended particularly for those applicants who have no reliable data
which indicates whether the field strength or power flux density figures would be exceeded by their
proposed radio facilities.  In such instances, the following is a suggested guide for determining whether
coordination is recommended:
 (i) All stations within 2.4 km (1.5 statute miles);
 (ii) Stations within 4.8 km (3 statute miles) with 50 watts or more effective radiated power (ERP) in
the primary plane of polarization in the azimuthal direction of the Table Mountain Receiving Zone;
 (iii) Stations within 16 km (10 statute miles) with 1 kW or more ERP in the primary plane of
polarization in the azimuthal direction of the Table Mountain Receiving Zone;
 (iv) Stations within 80 km (50 statute miles) with 25 kW or more ERP in the primary plane of
polarization in the azimuthal direction of the Table Mountain Receiving Zone.
(2) Applicants concerned are urged to communicate with the Radio Frequency Management Coordinator,
Department of Commerce, Research Support Services, NOAA/R/E5X2, Boulder Laboratories, Boulder
CO. 80303; telephone (303) 497-6548, in advance of filing their applications with the Commission.
(3) The Commission will not screen applications to determine whether advance consultation has taken
place.  However, applicants are advised that such consultation can avoid objections from the Department
of Commerce or proceedings to modify any authorization which may be granted which, in fact, delivers a
signal at the site in excess of the field strength specified herein.
(c) Applications for authorizations to construct microwave operational-fixed radio stations for transmission
of program material to cable television systems will not be accepted, except in the frequency bands above
21,200 MHz.
(d) Protection for Federal Communications Commission monitoring stations:
(1) Applicants in the vicinity of an FCC monitoring station for a radio station authorization to operate new
transmitting facilities or changed transmitting facilities which would increase the field strength produced
over the monitoring station over that previously authorized are advised to give consideration, prior to filing
applications, to the possible need to protect the FCC stations from harmful interference.  Geographical
coordinates of the facilities which require protection are listed in  0.121(c) of the Commission's Rules.
Applications for stations (except mobile stations) which will produce on any frequency a direct wave
fundamental field strength of greater than 10 mV/m in the authorized bandwidth of service (-65.8 dBW/m2
power flux density assuming a free space characteristic impedance of 120 ohms) at the referenced
coordinates, may be examined to determine extent of possible interference.  Depending on the theoretical
field strength value and existing root-sum-square or other ambient radio field signal levels at the indicated
coordinates, a clause protecting the monitoring station may be added to the station authorization.
(2) In the event that calculated value of expected field exceeds 10 mV/m (-65.8 dBW/m2) at the reference
coordinates, or if there is any question whether field strength levels might exceed the threshold value,
advance consultation with the FCC to discuss any protection necessary should be considered.
Prospective applicants may communicate with:  Chief, Field Operations Bureau, Federal Communications
Commission, Washington, D.C. 20554, Telephone (202) 632-6980.
(3) Advance consultation is suggested particularly for those applicants who have no reliable data which
indicates whether the field strength or power flux density figure indicated would be exceeded by their
proposed radio facilities (except mobile stations).  In such instances, the following is a suggested guide
for determining whether an applicant should coordinate:
 (i) All stations within 2.4 kilometers (1.5 statute miles);
 (ii) Stations within 4.8 kilometers (3 statute miles) with 50 watts or more average effective radiated
power (ERP) in the primary plane of polarization in the azimuthal direction of the Monitoring Stations.
 (iii) Stations within 16 kilometers (10 statute miles) with 1 kW or more average ERP in the primary
plane of polarization in the azimuthal direction of the Monitoring Station;
 (iv) Stations within 80 kilometers (50 statute miles) with 25 kW or more average ERP in the
primary plane of polarization in the azimuthal direction of the Monitoring Station;
(4) Advance coordination for stations operating above 1000 MHz is recommended only where the
proposed station is in the vicinity of a monitoring station designated as a satellite monitoring facility in 
0.121(c) of the Commission's rules and also meets the criteria outlined in paragraphs (i) (2) and (3) of this
section.
(5) The Commission will not screen applications to determine whether advance consultation has taken
place.  However, applicants are advised that such consultation can avoid objections from the Federal
Communications Commission or modification of any authorization which will cause harmful interference.
 101.125  Temporary fixed antenna height restrictions.
The overall antenna structure heights employed by mobile stations in the Local Television Transmission
Service and by stations authorized to operate at temporary fixed locations may not exceed the height
criteria set forth in Sec. 17.7 of this chapter, unless in each instance, authorization for use of a specific
maximum antenna height (above ground and above mean sea level) for each location has been obtained
from the Commission prior to erection of the antenna. Requests for such authorization must show the
inclusive dates of the proposed operation. (Complete information as to rules concerning the construction,
marking and lighting of antenna structures is contained in Part 17 of this chapter.)
 101.127  Topographical data.
Determining the location and height above sea level of the antenna site, the elevation or contour intervals
must be taken from United States Geological Survey Topographic Quadrangle Maps, United States Army
Corps of Engineers maps or Tennessee Valley Authority maps, whichever is the latest, for all areas for
which such maps are available. If such maps are not published for the area in question, the next best
topographic information should be used. Topographic data may sometimes be obtained from State and
municipal agencies. Data from Sectional Aeronautical Charts (including bench marks) or railroad depot
elevations and highway elevations from road maps may be used where no better information is available.
In cases where limited topographic data is available, use may be made of an altimeter in a car driven
along roads extending generally radially from the transmitter site. If it appears necessary, additional data
may be requested. United States Geological Survey Topographic Quadrangle Maps may be obtained
from the Department of the Interior, Geological Survey, Washington, DC 20242.   Sectional Aeronautical
Charts are available from the Department of Commerce, Coast and Geodetic Survey, Washington, DC
20230.
 101.129  Transmitter location.
(a) The applicant must determine, prior to filing an application for a radio station authorization, that the
antenna site specified therein is adequate to render the service proposed. In cases of questionable
antenna locations, it is desirable to conduct propagation tests to indicate the field intensity which may be
expected in the principal areas or at the fixed points of communication to be served, particularly where
severe shadow problems may be expected. In considering applications proposing the use of such
locations, the Commission may require site survey tests to be made pursuant to a developmental
authorization in the particular service concerned. In such cases, propagation tests should be conducted in
accordance with recognized engineering methods and should be made with a transmitting antenna
simulating, as near as possible, the proposed antenna installation. Full data obtained from such surveys
and its analysis, including a description of the methods used and the name, address and qualifications of
the engineer making the survey, must be supplied to the Commission.
(b) Antenna structures should be so located and constructed as to avoid making them hazardous to air
navigation. (See Part 17 of this chapter for provisions relating to antenna structures.) Such installation
must be maintained in good structural condition together with any required painting or lighting.
 101.131  Transmitter construction and installation.
(a) The equipment at the operating and transmitting positions must be so installed and protected that it is
not accessible to, or capable of being operated by, persons other than those duly authorized by the
licensee.
(b) In any case where the maximum modulating frequency of a transmitter is prescribed by the
Commission, the transmitter must be equipped with a low-pass or band-pass modulation filter of suitable
performance characteristics.  In those cases where a modulation limiter is employed, the modulation filter
must be installed between the transmitter stage in which limiting is effected and the modulated stage of
the transmitter.
(c) Each transmitter employed in these services must be equipped with an appropriately labeled pilot lamp
or meter which will provide continuous visual indication at the transmitter when its control circuits have
been placed in a condition to activate the transmitter. In addition, facilities must be provided at each
transmitter to permit the transmitter to be turned on and off independently of any remote control circuits
associated therewith.
(d) At each transmitter control point the following facilities must be installed:
 (1) A carrier operated device which will provide continuous visual indication when the transmitter
is radiating, or, in lieu thereof, a pilot lamp or meter which will provide continuous visual indication when
the transmitter control circuits have been placed in a condition to activate the transmitter.
 (2) Facilities which will permit the operator to turn transmitter carrier on and off at will.
(e) Transmitter control circuits from any control point must be so installed that grounding or shorting any
line in the control circuit will not cause the transmitter to radiate: Provided, however, That this provision
will not be applicable to control circuits of stations which normally operate with continuous radiation or to
control circuits which are under the effective operational control of responsible operating personnel 24
hours per day.
 101.133 Limitations on use of transmitters.
(a) Transmitters licensed for operation in Common Carrier services may not be concurrently licensed or
used for non-common carrier communication purposes except in the Multipoint Distribution Service (See
Part 21 of this Chapter). However, mobile units may be concurrently licensed or used for non-common
carrier communication purposes provided that the transmitter is type-accepted for use in each service.
(b) Private operational fixed stations authorized in this service may communicate with associated
operational-fixed stations and fixed receivers and with units of associated stations in the mobile service
licensed under Private Radio Service rule parts. In addition, intercommunication is permitted with other
licensed stations and with U.S. Government stations in those cases which require cooperation or
coordination of activities or when cooperative use arrangements in accordance with  101.135 are
contemplated; provided, however, that where communication is desired with stations authorized to
operate under the authority of a foreign jurisdiction, prior approval of this  Commission must be obtained;
And provided further, That the authority under  which such other stations operate does not prohibit the
intercommunication.
(c) Two or more persons or governmental entities eligible for private operational fixed licenses may use
the same transmitting equipment under the following terms and conditions:
 (1) Each licensee complies with the general operating requirements set out in this Part.
 (2) Each licensee is eligible for the frequency(ies) on which the facility operates.
 (3) Each licensee must have the ability to access the transmitter(s) that it is authorized to operate
under the multiple licensing arrangement.
 101.135  Shared use of radio stations and the offering of private carrier service.
(a) Licensees of Private Operational Fixed radio stations may share the use of their facilities on a
non-profit basis or may offer service on a for-profit private carrier basis, subject to the following conditions
and limitations:
 (1) Persons or governmental entities licensed to operate radio systems on any of the private radio
frequencies set out in  101.101 may share such systems with, or provide private carrier service to, any
eligible for licensing under this part, regardless of individual eligibility restrictions, provided that the
communications being carried are permissible under  101.603.
 (2) The licensee must maintain access to and control over all facilities authorized under its
license.
 (3) All sharing and private carrier arrangements must be conducted pursuant to a written
agreement to be kept as part of the station records.
 (4) The licensee must keep an up-to-date list of system sharers and private carrier subscribers
and the basis of their eligibility under this part. Such records must be kept current and must be made
available upon request for inspection by the Commission.
 101.137  Interconnection of private operational fixed microwave stations.
Private operational fixed stations may be interconnected with facilities of common carriers subject to
applicable tariffs.
 101.139  Authorization of transmitters.
(a) Except for transmitters used at developmental stations or for fixed point-to-point operation pursuant to
Subparts H and I, each transmitter must be a type which has been type accepted by the Commission for
use under the applicable rules of this part. Transmitters used in the point-to-point microwave service
under Subparts H and I for fixed operation must be of a type that has been either notified or type
accepted by the Commission (see Sec. 2.904(d) of this chapter). Effective March 5, 1984, only grants of
notification will be issued for transmitters used exclusively for fixed point-to-point operation. Transmitters
designed for use in the 31.0 to 31.3 GHz band will be authorized under the notification procedure.
(b) Any manufacturer of a transmitter to be produced for use under the rules of this part may request type
acceptance or notification by following the applicable procedures set forth in Part 2 of this chapter. Type
accepted and notified transmitters are included in the Commission's Radio Equipment List. Copies of this
list are available for inspection at the Commission's office in Washington, D.C. and at each of its field
offices.
(c) Type acceptance or notification for an individual transmitter may also be requested by an applicant for
a station authorization, pursuant to the procedures set forth in Part 2 of this chapter. An individual
transmitter will not normally be included in the Radio Equipment List but will be enumerated on the station
authorization.
(d) A transmitter presently shown on an instrument of authorization, which operates on an assigned
frequency in the 890-940 MHz band and has not been type accepted, may continue to be used by the
licensee without type acceptance provided such transmitter continues otherwise to comply with the
applicable rules and regulations of the Commission.
(e) Type acceptance or notification is not required for portable transmitters operating with peak output
power not greater than 250 mW.  If operation of such equipment causes harmful interference the FCC
may, at its discretion, require the licensee to take such corrective action as is necessary to eliminate the
interference.
(f)  After July 15, 1996,  the manufacture (except for export) or importation of equipment employing digital
modulation techniques in the 3700-4200, 5925-6425, 6525-6875, 10,550-10,680 and 10,700-11,700 MHz
bands must meet the minimum payload capacity requirements of  101.139.
 101.141 Microwave digital modulation.
(a) Microwave transmitters employing digital modulation techniques and operating below 15 GHz must,
with appropriate multiplex equipment, comply with the following additional requirements:
 (1) The bit rate, in bits per second, must be equal to or greater than the bandwidth specified by
the emission designator in Hertz (e.g., to be acceptable, equipment transmitting at a 20 Mb/s rate must
not require a bandwidth of greater than 20 MHz), except the bandwidth used to calculate the minimum
rate may not include any authorized guard band.
 (2) Equipment to be used for voice transmission placed in service, authorized, or applied for on or
before June 1, 1997 in  the 2110 to 2130 and 2160 to 2180 MHz bands must be capable of satisfactory
operation within the authorized bandwidth to encode at least 96 voice channels.  Equipment placed in
service, authorized, or applied for on or before June 1, 1997 in the 3700-4200, 5925-6425 (30 MHz
bandwidth), and 10,700-11,700 MHz (30 and 40 MHz bandwidths) bands must be capable of satisfactory
operation within the authorized bandwidth to encode at least 1152 voice channels.  These required
loading levels may be reduced by a factor of 1/N provided that N transmitters may be operated
satisfactorily, over the same radio path, within an authorized bandwidth less than, or equal to, the
maximum authorizable bandwidth (e.g., the 1152 channel requirement may be reduced to 576 if two
transmitters can be satisfactorily operated over the same path within the maximum bandwidth).  Where
type accepted equipment is designed to operate on the same frequency in a cross polarized configuration
to meet the above capacity requirements, the Commission will require, at the time additional transmitters
are authorized, that both polarizations of a frequency be used before a new frequency assignment is
made, unless a single transmitter installation was found to be justified by the Commission at the time it
authorized the first transmitter.
 (3) The following capacity and loading requirements must be met for equipment applied for,
authorized, and placed in service after June 1, 1997 in the 3700-4200 MHz (4 GHz), 5925-6425 and
6525-6875 MHz (6 GHz), 10,550-10,680 MHz (10 GHz), and 10,700-11,700 MHz (11 GHz) bands:

3/STS-1 = 672; 2 DS-3/STS-1 = 1344; 3 DS-3/STS-1 = 2016.
** This loading requirement must be met within 30 months of licensing.  If two
transmitters simultaneously operate on the same frequency over the same path, the
requirement is reduced to 25 percent.
 (4) If a transmitter is authorized to operate in a bandwidth that is not listed in paragraph (a)(3) of
this section, it must meet the minimum payload capacity and traffic loading requirements of the next
largest channel bandwidth listed in the table; e.g., if the authorized bandwidth is 3.5 MHz, the minimum
payload capacity must be 12.3 Mbits/s.
 (5) Transmitters carrying digital motion video motion material are exempt from the requirements
specified in paragraphs (a)(2) and (a)(3) of this section, provided that at least 50 percent of the payload is
digital video motion material and the minimum bit rate specified in paragraph (a)(1) is met.  In the 6, 10,
and 11 GHz bands, concatenation of multiple contiguous channels is permitted for channels of equal
bandwidth on center frequencies, provided no other channels are available and the minimum payload
capacity requirements are met.
(b) For purposes of compliance with the emission limitation requirements of  101.111(a)(2) of this part
and the requirements of paragraph (a) of this section, digital modulation techniques are considered as
being employed when  digital modulation occupies 50 percent or more to the total peak frequency
deviation of a transmitted radio frequency carrier.  The total peak frequency deviation will be determined
by adding the deviation produced by the digital modulation signal and the deviation produced by any
frequency division multiplex (FDM) modulation used. The deviation (D) produced by the FDM signal must
be determined in accordance with  2.202(f) of Part 2 of this chapter.
(c) Transmitters employing digital modulation techniques must effectively eliminate carrier spikes or single
frequency tones in the output signal to the degree which would be obtained without repetitive patterns
occurring in the signal.
(d) Transmitters type accepted for use with digital modulation prior to November 1, 1974 may continue to
be used where authorized until December 31, 1976. After the latter date, such equipment will no longer be
type accepted for digital modulation unless it is type accepted for such use after November 1, 1974.
(e) Microwave transmitters employing digital modulation techniques in the bands 17,700-19,700 MHz
must transmit at bit rate, in bits per second (bps), equal to or greater than the authorized bandwidth in
Hertz (e.g., to be acceptable, equipment transmitting at a 20 Mbps rate must not require an authorized
bandwidth greater than 20 MHz).  This bps/Hz standard is independent of the antenna (polarization) used,
frequency reuse, or how the system is configured.
 NOTE:  Until December 1, 1988, no minimum bit rate will apply to the 17,700-19,700 MHz band.
Systems authorized prior to that date may install equipment after that date with no minimum bit rate.
 101.143 Minimum path lengths for fixed lengths.
(a) The distance between end points of a fixed link in the private operational fixed service and the point-
to-point service must equal or exceed the value set forth in the table below or the EIRP must be reduced
in accordance with the equation set forth below.
                                                 Minimum path

1,850 to 7,125..........................................17
10,550 to 13,250........................................5
Above 17,700...........................................n/a
(b) For paths shorter than those specified in the Table, the EIRP may not exceed the value derived from
the following equation.
EIRP = 30 - 20 log[A/B], dBW
Where:
EIRP = Equivalent isotropic radiated power in dBW.
A = Minimum path length from the Table for the frequency band in kilometers.
B= The actual path length in kilometers.
NOTE: Automatic transmit power control may be used to meet this requirement up to a 3 dB increase in
EIRP.
(c) Upon an appropriate technical showing, applicants and licensees unable to meet the minimum path
length requirement may be granted an exception to these requirements.
 101.145 Interference to geostationary-satellites.
These limitations are necessary to minimize the probability of harmful interference to reception in the
bands 2655-2690 MHz, 5925-6875 MHz, and 12.7-12.75 GHz on board geostationary-space stations in
the fixed-satellite service (Part 25).
(a) Stations authorized prior to July 1, 1976 in the band 2655-2690 MHz, which exceed the power levels
in paragraphs (a) and (b) of this section are permitted to operate indefinitely, provided that the operations
of such stations does not result in harmful interference to reception in these band on board geostationary
space stations.
(b) 2655 to 2690 MHz and 5925 to 6875 MHz. No directional transmitting antenna utilized by a fixed
station operating in these bands may be aimed within 2 degrees of the geostationary-satellite orbit, taking
into account atmospheric refraction. However, exception may be made in unusual   circumstances upon a
showing that there is no reasonable alternative to the transmission path proposed. If there is no evidence
that such exception would  cause possible harmful interference to an authorized satellite system, said
transmission path may be authorized on waiver basis where the maximum value of the equivalent
isotropically radiated power (EIRP) does not exceed:
 (1) +47 dBW for any antenna beam directed within 0.5 degrees of the stationary satellite orbit or
 (2) +47 to +55 dBW, on a linear decibel scale (8 dB per degree) for any antenna beam directed
between 0.5 degrees and 1.5 degrees of the stationary orbit.
(c) 12.7 to 12.75 GHz. No directional transmitting antenna utilized by a fixed station operating in this band
may be aimed within 1.5 degrees of the  geostationary-satellite orbit, taking into account atmospheric
refraction.   However, exception may be made in unusual circumstances upon a showing that   there is no
reasonable alternative to the transmission path proposed. If there is no evidence that such exception
would cause possible harmful interference to an authorized satellite system, said transmission path may
be authorized on waiver basis where the maximum value of the equivalent isotropically radiated power
(EIRP) does not exceed +45 dBW for any antenna beam directed within 1.5 degrees of the stationary
satellite orbit.
(d) Methods for calculating the azimuths to be avoided may be found in: CCIR Report No. 393 (Green
Books), New Delhi, 1970; in "Radio-Relay Antenna   Pointing for controlled Interference With
Geostationary-Satellites" by C. W.   Lundgren and A. S. May, Bell System Technical Journal, Vol. 48, No.

Subpart D - Operational Requirements
 101.201  Station inspection.
The licensee of each station authorized in the radio services included in this part must make the station
available for inspection by representatives of the Commission at any reasonable hour.
 101.203  Communications concerning safety of life and property.
(a) Handling and transmission of messages concerning the safety of life or property which is in imminent
danger must be afforded priority over other messages.
(b) No person may knowingly cause to be transmitted any false or fraudulent message concerning the
safety of life or property, or refuse upon demand immediately to relinquish the use of a radio circuit to
enable the transmission of messages concerning the safety of life or property which is in imminent
danger, or knowingly interfere or otherwise obstruct the transmission of such messages.
 101.205  Operation during emergency.
The licensee of any station in these services may, during a period of emergency in which normal
communication facilities are disrupted as a result of hurricane, flood, earthquake, or similar disaster,
utilize such station for emergency communication service in a manner other than that specified in the
instrument of authorization: Provided, (a) That as soon as possible after the beginning of such emergency
use, notice be sent to the Commission at Washington, D.C. stating the nature of the emergency and the
use to which the station is being put, and (b) that the emergency use of the station must be discontinued
as soon as substantially normal communication facilities are again available, and (c) that the Commission
at Washington, D.C. must be notified immediately when such special use of the station is terminated, and
(d) that, in no event, will any station engage in emergency transmission on frequencies other than, or with
power in excess of, that specified in the instrument of authorization or as otherwise expressly provided by
the Commission, or by law, and (e) that the Commission may, at any time, order the discontinuance of
any such emergency communication.
 101.207  Suspension of transmission.
Transmission must be suspended immediately upon detection by the station or operator licensee or upon
notification by the Commission of a deviation from the technical requirements of the station authorization
and must remain suspended until such deviation is corrected, except for transmission concerning the
immediate safety of life or property, in which case transmission must be suspended immediately after the
emergency is terminated.
 101.209  Operation of stations at temporary fixed locations for communication between the United
States and Canada or Mexico.
Stations authorized to operate at temporary fixed locations may not be used for transmissions between
the United States and Canada, or the United States and Mexico, without prior specific notification to, and
authorization from, the Commission. Notification of such intended usage of the facilities should include a
detailed showing of the operation proposed, including the parties involved, the nature of the
communications to be handled, the terms and conditions of such operations, the time and place of
operation, such other matters as the applicant deems relevant, and a showing as to how the public
interest, convenience and necessity would be served by the proposed operation. Such notification should
be given sufficiently in advance of the proposed date of operation to permit any appropriate correlation
with the respective foreign government involved (see   101.717, 101.811, 101.813, and 101.815).
 101.211 Operator requirements for Private Operational Fixed Stations.
(a) No operator license is required for the operation, maintenance, or  repair of stations licensed under
this part.
(b) An unlicensed person, with the consent or authorization of the licensee, may employ stations in this
service for the purpose of telecommunications in accordance with the conditions and limitations set  forth
in  101.135 of this part.
(c) The station licensee is responsible for the proper operation of the station at all times and is expected
to provide for observations, servicing and maintenance as often as may be necessary to ensure proper
operation. All adjustments or tests during or coincident with the installation, servicing, or maintenance of
the station should be performed by or under the immediate supervision and responsibility of a person
technically qualified to perform transmitter installation, operation, maintenance, and repair duties in the
private land mobile services and fixed services by an organization or committee representative of users in
those services.
(d) The provisions of paragraph (b) of this section authorizing unlicensed  persons to operate stations may
not be construed to change or diminish in  any respect the responsibility of station licensees to have and
to maintain  control over the stations licensed to them (including all transmitter units  thereof), or for the
proper functioning and operation of those stations  (including all transmitter units thereof) in accordance
with the terms of the licenses of those stations.
 101.213  Station identification.
Stations in the private service are exempt from the requirement to identify transmissions by call sign or
any other station identifier.
Subpart E - Miscellaneous Common Carrier Provisions
 101.301  National defense; free service.
Any common carrier authorized under the rules of this part may render to any agency of the United States
Government free service in connection with the preparation for the national defense. Every such carrier

(l) 12,200-12,700 MHz: The Commission has allocated the 12.2-12.7 GHz band for use by the
broadcasting-satellite service. Operational-fixed stations authorized after September 9, 1983 will be
licensed on a noninterference basis and are required to make any and all adjustments necessary to
prevent interference to operating domestic broadcasting-satellite systems. Notwithstanding any other
provisions, no operational-fixed stations are permitted to cause interference to broadcasting-satellite
stations of other countries operating in accordance with the Region 2 plan for the broadcasting-satellite
service established at the 1983 RARC.

(q) Fixed systems licensed, in operation, or applied for in the 6525-6875 and 10,550-10,680 MHz bands
prior to July 15, 1993 are permitted to use channel plans in effect prior to that date, including adding
channels under those plans.
(r) Frequency diversity transmission will not be authorized in this service in the absence of a factual
showing that the required communications cannot practically be achieved by other means. Where
frequency diversity is deemed to be justified on a protection channel basis, it must be limited to one
protection channel for the bands 3700-4200, 5925-6425, and 6525-6875 MHz, and a ratio of one
protection channel for three working channels for the bands 10,550-10,680 and 10,700-11,700 MHz. In
the bands 3700-4200, 5925-6425, and 6525-6875 MHz, no frequency diversity protection channel will be
authorized unless there is a minimum of three working channels, except that where a substantial showing
is made that a total of three working channels will be required within three years, a protection channel
may be authorized simultaneously with the first working channel. A protection channel authorized under
such exception will be subject to termination if applications for the third working channel are not filed
within three years of the grant date of the applications for the first working channel. Where equipment
employing digital modulation techniques with cross-polarized operation on the same frequency is used,
the protection channel authorized under the above conditions may be considered to consist of both
polarizations of the protection frequency where such is shown to be necessary.
 101.607  Maximum authorized bandwidth
The maximum bandwidth which will be authorized per frequency assigned is set out in the table that
follows.  Regardless of the maximum authorized  bandwidth specified for each frequency band, the
Commission reserves the right to issue a license for less than the maximum bandwidth if it appears that a

 101.701 Eligibility.
(a) Authorizations for stations in this service will be issued to existing  and proposed common carriers.
Applications will be granted only in cases in  which it is shown that:
 (1) The applicant is legally, technically, financially and otherwise  qualified to render the proposed
service;
 (2) There are frequencies available to enable the applicant to render a  satisfactory service; and
 (3) The public interest, convenience, and necessity would be served by a  grant thereof.
(b) If the content is originated, selected, controlled, or otherwise  substantively influenced by the
applicant, licensee, or a closely affiliated  entity, no station or radio frequency in this service will be
authorized, or  may be utilized, to transmit any closed circuit television signals or  television signals other
than broadcast television signals, unless:
 (1) Such service is otherwise permitted for a specific length of time by  grant of an acceptable
petition for waiver of this rule; or
 (2) Such service is otherwise permitted by a condition in the applicable  instrument of
authorization; or
 (3) Such service is provided pursuant to applicable FCC tariff and is  temporary and occasional
intra-company television communication for  management, network supervision, or other internal carrier
functions.
For purposes of this paragraph, an entity will be considered to be "closely  affiliated" with an applicant if it
is in a parent-subsidiary relationship,  or both are commonly controlled, or they have any common officers
or  management employees.
(c) Applications for stations or frequencies that will be used primarily to  relay broadcast television signals
must include a demonstration (including  appropriate system diagrams and tables) that at least fifty
percent of the  customers (or points of service) on the microwave system involved, including  those
served through an interconnecting carrier(s), receiving applicant's  service, will not be related or affiliated
in any degree with the applicant,  and that the proposed usage by such customers, in terms of hours of
use and  channels delivered, must constitute at least fifty percent of the usage of the applicant's
microwave service. Applications that do not contain these demonstrations will be returned as
unacceptable for filing.

These channels are assigned for use within a rectangular service area to be  described in the application
by the maximum and minimum latitudes and  longitudes. Such service area must be as small as
practicable consistent  with the local service requirements of the carrier. These frequency plans may  be
subdivided as desired by the licensee and used within the service area as  desired without further
authorization subject to the terms and conditions set  forth in  101.723. These frequencies may be
assigned only where it is  shown that the applicant will have a reasonable projected requirement for a
multiplicity of service points or transmission paths within the area.
(l) Fixed systems licensed, in operation, or applied for in the 5925-6425, 10,550-10,680, and 10,700-

(b) The bandwidths authorized on frequencies above 500 MHz must be appropriate to the type of
operation in any particular case. An application requesting such authorization must fully describe the
modulation, emission, and bandwidth desired and must specify the bandwidth to be occupied.
 101.709 Modulation requirements.
When amplitude modulation is used, the modulation percentage must be sufficient to provide efficient
communication, and must normally be maintained above 70 percent on positive peaks but may not
exceed 100 percent on negative peaks.
 101.711 Permissible communications.
Stations in this service are authorized to render any kind of communication service provided for in the
legally applicable tariffs of the carrier, unless otherwise directed in the applicable instrument of
authorization or limited by  101.703 or  101.707.
 101.713 Supplementary showing required with applications.
(a) All applicants for regular authorization under this subpart must, before filing an application,
amendments to a pending application or modifications to a license, prior coordinate the proposed
frequency usage with existing users in the area and other applicants with previously filed applications in
accordance with the procedures in  101.103 except that stations authorized under  101.715 may
complete the prior coordination process orally and the period allowed for response to a coordination
notification may be less than 30 days if the parties agree.
(b) In those frequency bands shared with the communication-satellite service and applicant for a new
station, for new points of communication, for the initial frequency assignment in a shared band for which
coordination has not been previously effected, or for authority to modify the emission or radiation
characteristics of an existing station in a manner that may increase the likelihood of harmful interference,
must ascertain in advance whether the station(s) involved lie within the great circle coordination distance
contours of an existing Earth station or one for which an application has been accepted for filing, and
must coordinate his proposal with each such Earth station operator or applicant. For each potential
interference path, the applicant must perform the computations required to determine that the expected
level of interference to or from the terrestrial station does not exceed the maximum permissible
interference power level in accordance with the technical standards and requirements of Secs. 25.251-
25.256 of this chapter. In those instances where the results of these computations indicate a safety
margin of less than 5 dB, the applicant must submit with the application to the Commission, certain
additional information; the gains assumed for both the terrestrial and Earth station antennas in the
direction of the other station; the calculated transmission loss; and the resulting margin above the
controlling objective. The Commission may, in the course of examining any application, require the
submission of additional showings, complete with pertinent data and calculations in accordance with Part
25 of this chapter, showing that harmful interference will not likely result from the proposed operation.
(Technical characteristics of the Earth stations on file and coordination contour maps for those Earth
stations will be kept on file for public inspection in the offices of the Commission's Common Carrier
Bureau in Washington, D.C.)
(c) Each applicant filing pursuant to paragraph (c) of this section must also ascertain in advance whether
the beam of his proposed antenna(s) intersects the beam of any Earth station antenna within the rain
scatter coordination distance contour of which the terrestrial antenna is located, below the altitude given
in table 1 of Sec. 25.254(b) of this chapter for the rain climate in which the Earth station is located. In
general such intersections will not be permitted. For the purposes of this paragraph, the beam of an
antenna is to be taken as that portion of the antenna radiation pattern inside of which the gain is within 15
dB of the maximum antenna gain. The concepts of rain climate and rain scatter coordination distance
contour are as defined in Sec. 25.254 of this chapter. In certain cases, for good cause shown,
intersections may be permitted on an individual waiver basis. In such cases, the applicant must also
submit with his application a showing setting forth (1) the nature of the proposed beam intersection, (2)
the Earth station operator or applicant with whom coordination was attempted and the results of the
coordination, and (3) the technical basis on which it was concluded that harmful interference will not likely
result from this beam intersection.
 101.715 Stations at temporary fixed locations.
(a) Authorizations may be issued upon proper application for the use of frequencies listed in
  101.703(a) by stations in the Point-to-Point Microwave Radio Service for rendition of temporary service
to subscribers under the following conditions:
 (1) When a fixed station is to remain at a single location for less than six months, the location is
considered to be temporary. Services which are initially known to be of longer than 6 months' duration
may not be provided under a temporary fixed authorization but rendered pursuant to a regular license.
       (2) When a fixed station, authorized to operate at temporary locations, is to remain at a single
location for more than six months, an application (FCC Form 494) for a station authorization designating
that single location as the permanent location must be filed at least 30 days prior to the expiration of the
