PLAN TO SELECT SPECTRUM\
FOR THIRD GENERATION (3G) WIRELESS SYSTEMS\
in the UNITED STATES\
October 20, 2000

**I. [PRESIDENTIAL MEMORANDUM (PM)]{.underline}**

President Clinton signed a memorandum dated October 13, 2000,
(Attachment 1) that states the need and urgency for the United States to
select radio frequency spectrum to satisfy the future needs of the
citizens and businesses for mobile voice, high speed data, and Internet
accessible wireless capability; the guiding principles to be used for
the development of 3G wireless systems; and the direction to the Federal
agencies to carry out the selection of spectrum.

In summary, the President directed

-   the Secretary of Commerce in cooperation with the Federal
    Communications Commission (FCC) to:

```{=html}
<!-- -->
```
-   develop a plan by October 20, 2000, for the identification and
    analysis of possible spectrum bands for 3G services that would
    enable the FCC to select specific frequencies by July 2001 for 3G
    and complete the auction for licensing 3G wireless providers by
    September 30, 2002.

```{=html}
<!-- -->
```
-   issue an interim report by November 15, 2000, on the current
    spectrum uses, and the potential for the sharing or segmenting, of
    two of the bands identified at the World Radiocommunication
    Conference (WRC-2000) for 3G wireless use, 1755-1850 MHz and
    2500-2690 MHz, about which the United States does not have
    sufficient knowledge at present to make a considered decision about
    allocation.

-   work with government and industry representatives through a series
    of public meetings to develop recommendations and plans for
    identifying spectrum for 3G wireless systems.

-   the Secretary of Defense, Secretary of the Treasury, Secretary of
    Transportation, Department of State and heads of any other executive
    department or agency that currently use any of the spectrum
    identified at the WRC-2000 for 3G systems to participate and
    cooperate with the government-industry group as established above by
    the Secretary of the Commerce.

-   the Department of State to coordinate and present the evolving views
    of the United States to foreign governments and international
    bodies.

All of the above work is expected to lead to the issuance of a final
report by March 1, 2001, that describes the potential use of all
identified bands for 3G wireless applications.

The President encouraged the FCC to participate in the
government-industry program being led by the Secretary of Commerce and
complete rulemaking for spectrum allocation in full coordination with
the Assistant Secretary of Commerce for Communications and Information
(Administrator, National Telecommunications and Information
Administration (NTIA)) by July 2001.

**II. [BACKGROUND]{.underline}**

Over the past decade, there has been enormous worldwide growth in the
use of mobile radios. Studies in the International Telecommunication
Union (ITU) and elsewhere indicate that this growth in personal
communications is likely to continue. First and second generations of
personal communications service (PCS) are operating now. The 3G PCS will
provide mobile and satellite-based broadband capabilities, and represent
a path for the evolution of existing cellular and PCS. A summary of
various administrations\' spectrum usage (cellular and PCS) and planned
3G wireless is shown in Attachment 2.

The ITU Radiocommunication Sector has addressed the characteristics of a
3G system and has termed it International Mobile Telecommunications-2000
(IMT-2000). Key features of IMT-2000 include: a high degree of
commonality of design worldwide; compatibility of services within
IMT-2000; and high-quality worldwide use and roaming capability for
multi-media applications (e.g. video-teleconferencing and high-speed
Internet access). The following was considered by the ITU\'s 2000
WRC-2000: \"review of spectrum and regulatory issues for advanced mobile
applications in the context of IMT-2000, noting that there is an urgent
need to provide more spectrum for the terrestrial component of such
applications and that priority should be given to terrestrial mobile
needs, and adjustments to the Table of Frequency Allocations as
necessary\"[(1)](#N_1_).

The 698-960 MHz, 1710-1885 MHz, 2500-2690 MHz and the 2700-2900 MHz
bands were some of the bands that WRC-2000 considered for IMT-2000
terrestrial systems. The United States position for this conference was
established among U.S. industry and government representatives,
resulting in a proposal that the United States believed could be the
basis for a compromise at the conference, given the conflicting
positions of many of the other administrations. The United States and
many ITU Region II administrations proposed no change to the allocations
in the 2700-2900 MHz band. The United States also suggested three
possible bands for terrestrial IMT-2000, including the 1710-1885 MHz
band (favored by the Americas), the 2500-2690 MHz band (favored by
Europe), and the 698-960 MHz band. At the conference, the United States
stated that it would study the 1755-1850 MHz and 2500-2690 MHz bands
domestically to (1) see if there are alternate bands to relocate the
existing systems, (2) determine the costs of any required relocation,
(3) identify who would pay for relocation, and (4) assess how long the
transition would take. The United States proposed, and the WRC-2000
adopted, full regulatory flexibility, giving each administration the
right to determine which band it may want to identify for IMT-2000, if
it wants to do so at all. Administrations can identify these bands at
any time. Also, the United States proposed to keep bands identified for
IMT-2000 open to any technology that fits in the mobile service rather
than specifying a technology or standard for use in the spectrum.

WRC-2000 identified the 806-960, 1710-1885, and 2500-2690 MHz bands for
terrestrial IMT-2000. The 1525-1559, 1610-1660.5, 2483.5-2500, 2500-2520
and 2670-2690 MHz bands were identified for the satellite portion of
IMT-2000. These bands are shown in Attachment 2. The conference also
adopted a resolution pointing out that some countries may implement
IMT-2000 in the 698-806 and 2300-2400 MHz bands. The WRC-2000 agreed
that the identification of these bands does not preclude the use of
these bands by any application of services to which they are allocated,
and does not establish priority in the Radio Regulations.
Administrations can implement any bands in any timeframe, for any
service or technology, and may use any portion of the bands that they
deem appropriate, based on national requirements. All of these bands are
used at present. For those who may be required to relocate, additional
spectrum may have to be found or other accommodations will have to be
made to continue their operations.

The United States recognizes that discussions relative to spectrum for
advancing mobile telecommunications systems are vital for
administrations to plan their spectrum use, and for industry to plan how
it will meet the marketplace needs of the future. The United States
supports the development and implementation of advancing mobile
telecommunications systems, such as IMT-2000, as critical components of
the communications and information infrastructure of the future.

In addition to the three WRC-2000 bands, other bands that could be
considered in the United States are: 698-746, 746-764, 776-794, 806-960
(includes the present U.S. cellular), 1710-1850, 1850-1990 (present PCS
bands), 2110-2150, 2160-2165 and 2500-2690 MHz. A brief description of
these bands is contained in Attachment 3. All these bands will be given
full consideration in the formulation of the final allocation order. For
some of these bands, no extensive studies are required to provide
decision-makers with a factual basis for a decision. However, in order
to achieve a full understanding of all the options available, the FCC
and NTIA need to undertake studies of the frequency ranges of 1755-1850
MHz and 2500-2690 MHz. The studies\' purpose is to determine whether,
and under what conditions, these bands could be made available for 3G
wireless systems and the costs and operating impacts to the incumbent
users. These analyses are the subject of the study plan described below.

**III. [STUDIES]{.underline}**

**A. Overview**

The NTIA will study the 1755-1850 MHz band, and the FCC will study the
2500-2690 MHz band. It is important that the studies be based on the
same assumptions where applicable and address common spectrum options.
The two studies will proceed along the same timelines and use similar
assumptions to assure equal treatment for both.

The results of the two studies, relevant information regarding the other
bands identified in Section II, above, (806-960, 1710-1755, 2110-2150,
2160-2165 MHz) and public comment generated either during the Secretary
of Commerce\'s government-industry dialogue (*see* Section IV,
\"Outreach,\" below) or in response to the FCC\'s Notice of Proposed
Rulemaking will be taken into consideration when reviewing the overall
spectrum requirements and future plans for 3G. Among other things, there
will be an evaluation of private sector plans to migrate their 1G and 2G
systems to 3G in the existing bands they already have. National security
and public safety will also be taken in account. In addition, among
other factors, the U.S. will also have to consider the ramifications of
the deployment of 3G elsewhere in the world with regard to possible
spectrum harmonization that could lead to global roaming.

The analysis will also have to take into account the provisions of the
FY 00 National Defense Authorization Act, which requires that before
there can be any reallocation of spectrum where the Department of
Defense is a primary user, which includes 1755-1850 MHz, certain
conditions must be met: (1) NTIA, in consultation with the FCC, must
identify and make available to the Department of Defense an alternative
band or bands of frequencies as a replacement; and (2) the Secretary of
Commerce, the Secretary of Defense, and the Chairman of the Joint Chiefs
of Staff have jointly certified to specified committees of the Congress
that the replacement band or bands of frequencies provides comparable
technical characteristics to restore essential military capability that
will be lost as a result of this reallocation. The same analysis will
apply if the DoD is a primary user of a band selected as an alternate
band in which to place incumbent users of the candidate bands.

**C. Spectrum Sharing/Relocation Options**

Using the information above, the study will include a technical
evaluation of the following sharing/relocation options:

> 1\. **System Sharing.** An evaluation of the current and planned
> systems in the candidate bands to share with 3G systems.
>
> 2\. **Band/Channel Segmentation.**

The studies will assess the feasibility of dividing the candidate bands
into segments and/or channels and evaluating how the incumbent and 3G
systems would share these segments and/or channels to meet their
respective radiocommunication requirements. The FCC will propose
possible segmentation plans for both 1755-1850 and 2500-2690 MHz bands
to evaluate as part of the interim band studies. These options may also
consider use of the 1710-1755 and 2110-2160 MHz segments. Additional
segmentation possibilities may be evaluated later in the process. 3G
alternate plans and 1G/2G migration could have a bearing on this option.

Studies for both sharing and segmentation will use generally-accepted
interference protection criteria, where available, for determining
unacceptable levels of interference. Studies will also consider possible
operational methods to mitigate potential interference while retaining
the capability to perform the same mission or service in light of
current requirements.

> 3\. **Band/Channel Segmentation & Alternate Band Combination.** If the
> candidate bands could not support all requirements of the incumbents
> and 3G simultaneously, identification of alternate bands to satisfy
> requirements would be required.
>
> 4\. **Alternate Bands Only.** Relocate incumbents to other bands if
> necessary.
>
> 5\. **Other Options**. Potential combination of the above.

For each of options above, the evaluation will consider implementation
of the option by the end of 2003, 2006, 2010 or any other variant that
is costed out above.

**IV. [OUTREACH]{.underline}**

The President\'s Memorandum instructs the Secretary of Commerce to work
with government and industry representatives through a series of regular
public meetings to develop recommendations and plans for identifying
spectrum for 3G wireless systems. Additionally, it directs the Federal
agencies that use the spectrum, and urges the FCC, to participate and
cooperate with the government-industry group. NTIA, on behalf of the
Secretary of Commerce, will act as the primary facilitator in the
Department\'s outreach program. Each Federal agency will designate a
person to represent the agency to attend these public meetings. The
following activities are planned to carry out the President\'s
direction:

> **A. Initial Ideas and Positions**. NTIA will invite industry
> representatives to articulate their ideas and positions for selection
> of spectrum for 3G and to suggest industry initiatives to supplement
> this plan. Areas of discussion could include anticipated 3G spectrum
> requirements, band segmentation, 1G/2G/2.5G migration, alternate bands
> for incumbents, short and long range plans, and global roaming
> considerations. Representatives will be asked to submit their ideas
> and positions in writing. NTIA, on behalf of the Secretary of
> Commerce, will schedule an opportunity for industry representatives to
> explain their ideas and positions. Based on this initial information,
> subsequent meetings may be held.
>
> **B. Interim Reports.** The FCC and NTIA will release their interim
> reports to the public on November 15. NTIA will ask industry for
> comments. Subsequent meetings may be held depending on the nature of
> the comments.
>
> **C. FCC Notice of Proposed Rulemaking (NPRM).** The FCC plans to
> release a NPRM on 3G in December which will include information from
> the interim reports. The FCC will receive comments on the NPRM. The
> FCC and NTIA will hold joint information exchange meetings with
> industry representatives relative to the comments.
>
> **D. Final Report**. The FCC and NTIA will release their final reports
> on March 1, 2001, describing all identified bands for 3G wireless use.
> Industry will be asked to comment on these reports.

**V. [FCC PROCESS DESCRIPTION AND PLAN]{.underline}**

The FCC is responsible for allocating spectrum for non-government uses.
The Commission allocates spectrum through the rule making process in
accordance with the Administrative Procedures Act. The process generally
begins when an organization or member of the public submits a petition
for rule making requesting a change in the United States Table of
Frequency Allocations contained in Section 2.806 of the FCC rules. The
Commission issues a public notice inviting comment on such petitions. If
the Commission finds that the petition has merit, it issues a Notice of
Proposed Rule Making (NPRM). The public is afforded an opportunity to
file comments which the Commission must consider before arriving at a
final decision. The Commission then adopts a Report and Order that makes
changes to the Table of Frequency Allocations as appropriate.

The Commission recently received two petitions for rule making
requesting spectrum allocations for 3G mobile services. The Cellular
Telecommunications Industry Association (CTIA) submitted a petition
(RM-9920) asking the Commission to allocate spectrum for 3G terrestrial
mobile services, and in particular to conduct studies to consider use of
the 1755-1850 MHz and 2500-2690 MHz bands identified at WRC-2000. The
Satellite Industry Association (SIA) submitted a petition (RM-9911)
asking the Commission to allocate the 2500-2520 MHz and 2670-2690 MHz
bands for the mobile satellite service for the mobile component of 3G
services. Comments were filed on both petitions on September 12, 2000.

The Commission plans to initiate a Notice of Proposed Rule Making by the
end of this year proposing spectrum allocations for fixed and mobile
services that would be available for 3G terrestrial mobile services. It
is anticipated that the Notice of Proposed Rule Making will consider the
frequency bands identified in attachment 1. Further, the NPRM is
expected to consider the future role of the cellular and PCS services in
providing 3G services. The NPRM may consider other relevant frequency
bands that may be used to serve the demand for 3G terrestrial services.
A number of factors will be considered in developing proposed
allocations, including the studies of 1755-1850 MHz and 2500 - 2690 MHz
bands.

A Report and Order (R&O) is planned to be completed by July 2001
allocating spectrum for fixed and mobile services that will be available
for 3G services. The allocation decisions will be based on the comments
filed on the Notice of Proposed Rule Making and studies of the 1755
-1850 MHz and 2500 - 2690 MHz bands, and any other relevant information.

The Commission routinely coordinates frequency allocations that may
affect government use of the spectrum with the NTIA. Because certain of
the frequency bands of interest are allocated to the Federal Government,
the Commission will closely coordinate both the NPRM and R&O with NTIA.

The spectrum allocation proceeding will be followed by another rule
making proceeding to establish service rules. The service rule
proceeding will be completed in time to complete auctions of the
licenses by September 30, 2002.

**For Immediate Release October 13, 2000**

**October 13, 2000**

**MEMORANDUM FOR THE HEADS OF EXECUTIVE DEPARTMENTS AND AGENCIES**

**SUBJECT: Advanced Mobile Communications/Third Generation Wireless
Systems**

The United States and the rest of the world are on the verge of a new
generation of personal mobile communications, as wireless phones become
portable high-speed Internet connections. The United States Government
must move quickly and purposefully so that consumers, industry, and
Government agencies all reap the benefits of this third generation of
wireless products and services.

In less than 20 years, the U.S. wireless industry has blossomed from
virtually nothing to one with 100 million subscribers, and it continues
to grow at a rate of 25 to 30 percent annually. Globally, there are over
470 million wireless subscribers, a number expected to grow to
approximately 1.3 billion within the next 5 years. It is an industry in
which U.S. companies have developed the leading technologies for current
and future systems. It is an industry whose products help people
throughout the world communicate better and in more places, saving time,
money, and lives.

Many saw the first generation of wireless \-- cell phones \-- as an
extravagant way to make telephone calls. Yet as with all communications
systems, the value of wireless communications increased as the number of
users and types of use increased. Today\'s second generation wireless
technology increased services and information offered to users and
increased competition among providers. Digital \"personal communications
services\" provide added messaging and data features, including such
services as voice mail, call waiting, text messaging, and, increasingly,
access to the World Wide Web. These first and second generation services
increased productivity and reduced costs for thousands of businesses as
well as Government agencies.

The next generation of wireless technology holds even greater promise.
Neither the first nor the second generation of wireless technologies
were designed for multi-media services, such as the Internet. Third
generation wireless technologies will bring broadband to hand-held
devices. Higher speeds and increased capability will lead to new audio,
video, and other applications, which may create what many are calling
\"mobile-commerce\" (m-commerce) that people will use in ways that are
unimaginable today. Moreover, an international effort is underway to
make it possible for the next generation of wireless phones to work
anywhere in the world.

The Federal Government has always played a crucial role in the
development of wireless services. To foster the development of cellular
telephone service, the Federal Government made available radio frequency
spectrum that had previously been used by other commercial and
Government services. For the second generation \-- digital PCS \-- the
Federal Government allocated spectrum in bands occupied by private
sector users, and ensured competition by awarding numerous licenses,
while maintaining technology neutrality.

The United States has also placed a high value on promoting Internet
access. Government support for the development of third generation
wireless systems will help combine the wireless revolution with the
Internet revolution. As part of these efforts, radio spectrum must be
made available for this new use. The United States has already been
active by, among other things, participating at the World
Radiocommunication Conference 2000 (WRC-2000) earlier this year.
WRC-2000 adopted the basic principles of the U.S. position, which was
negotiated by Government and industry stakeholders: (1) governments may
choose spectrum from any one or all of the bands identified for third
generation mobile wireless; (2) governments have the flexibility to
identify spectrum if and when they choose; and (3) no specific
technology will be identified for third generation services. This result
will allow deployment of the best technologies and permit the United
States to move forward with rapid deployment of third generation
services in a way that advances all U.S. interests.

The spectrum identified by international agreement at WRC-2000, however,
is already being used in the United States by commercial
telecommunications, television, national defense, law enforcement, air
traffic control, and other services. Similar difficulties in making
spectrum available for third generation mobile wireless systems are
evident in other parts of the world. Because different regions have
already selected different bands, there almost certainly will be a few
preferred bands rather than a single band for third generation services.
In the United States, Federal Government agencies and the private sector
must work together to determine what spectrum could be made available
for third generation wireless systems.

Accordingly, I am hereby directing you, and strongly encouraging
independent agencies, to be guided by the following principles in any
future actions they take related to development of third generation
wireless systems:

\-- Third generation wireless systems need radio frequency spectrum on
which to operate. Executive departments and agencies and the Federal
Communications Commission (FCC) must cooperate with industry to identify
spectrum that can be used by third generation wireless systems, whether
by reallocation, sharing, or evolution of existing systems, by July
2001;

\-- Incumbent users of spectrum identified for reallocation or sharing
must be treated equitably, taking national security and public safety
into account;

\-- The Federal Government must remain technology-neutral, not favoring
one technology or system over another, in its spectrum allocation and
licensing decisions;

\-- The Federal Government must support policies that encourage
competition in services and that provide flexibility in spectrum
allocations to encourage competition; and

\-- The Federal Government must support industry efforts as far as
practicable and based on market demand and national considerations,
including national security and international treaty obligations, to
harmonize spectrum allocations regionally and internationally.

I also direct the relevant agencies as follows:

1\. I direct the Secretary of Commerce to work cooperatively with the
FCC, as the agencies within the Federal Government with shared
responsibility and jurisdiction for management of the radio frequency
spectrum, to develop, by October 20, 2000, a plan to select spectrum for
third generation wireless systems, and to issue, by November 15, 2000,
an interim report on the current spectrum uses and potential for
reallocation or sharing of the bands identified at WRC-2000 that could
be used for third generation wireless systems, in order that the FCC can
identify, in coordination with the National Telecommunications and
Information Administration, spectrum by July 2001, and auction licenses
to competing applicants by September 30, 2002.

2\. I also direct the Secretary of Commerce to work cooperatively with
the FCC to lead a government-industry effort, through a series of
regular public meetings or workshops, to work cooperatively with
government and industry representatives, and others in the private
sector, to develop recommendations and plans for identifying spectrum
for third generation wireless systems consistent with the WRC-2000
agreements, which may be implemented by the Federal Government.

3\. I direct the Secretaries of Defense, the Treasury, Transportation,
and the heads of any other executive department or agency that is
currently authorized to use spectrum identified at WRC-2000 for third
generation wireless services, to participate and cooperate in the
activities of the government-industry group.

4\. I direct the Secretary of State to participate and cooperate in the
activities of the government-industry group, and to coordinate and
present the evolving views of the United States Government to foreign
governments and international bodies.

Furthermore, I strongly encourage the FCC to participate in the
government-industry outreach efforts and to initiate a rule-making
proceeding to identify spectrum for third generation wireless services
that will be coordinated with the Assistant Secretary of Commerce for
Communications and Information during the formulation and decision
making process with the goal of completing that process by July 2001, so
that such spectrum can be auctioned to competing applicants for licenses
by September 30, 2002.

ATTACHMENT 3 TO APPENDIX 1.1\
Spectrum Use Summary in the United States\
(October 18, 2000)

1\. **698-746 MHz (TV channels 52 - 59) Band.** This spectrum is
allocated in Region 2, which includes the United States, on a primary
basis to the Broadcasting and on a secondary basis to the Fixed and
Mobile Services. In addition, within the 698-746 MHz band segment,
assignments may be made to television stations using frequency
modulation in the Broadcasting-satellite Service subject to agreement
between administrations concerned and those having services that might
be affected. This spectrum is currently designated as TV channels 52-59
and is used by existing analog full service stations, Low Power TV
stations, TV translator and booster stations, and new DTV television
stations. In the United States, this band is allocated on a primary
basis to the Broadcasting Service. This band is also allocated to the
Fixed Service to permit subscription television operations. Further, TV
broadcast licensees are permitted to use subcarriers on a secondary
basis for both broadcast and non-broadcast purposes. The Balanced Budget
Act of 1997 requires this spectrum to be reallocated and auctioned by
September 30, 2002. Existing TV service and the service of new digital
television (DTV) stations will continue on channel allotments in this
band until at least December 31, 2006, when the transition to DTV
service is scheduled to end and all television stations are to be
located on channels in the DTV core spectrum (Channels 2-51). Television
stations will cease operations on these channels at the end of the DTV
transition, or possibly later on a market-by-market and
channel-by-channel basis, depending on the availability of DTV
television service and receivers. The rules for any new services on
698-746 MHz frequencies provide for the protection of those stations
during the DTV transition. The WRC results recognize that some
administrations may choose to provide for 3G services in this spectrum.

2\. **746-806 MHz** **(TV Channels 60-69) Band**. The Federal
Communications Commission (FCC) has reallocated this spectrum in
accordance with the 1997 Balanced Budget Act. Specifically, the 36
megahertz of spectrum at 746-764 MHz and 776-794 MHz (TV channels 60-62
and 64-66) was reallocated for fixed, mobile and new broadcast services
for commercial uses. The 24 megahertz of spectrum at 764-776 MHz and
794-806 MHz (TV channels 63-64 and 68 - 69) were reallocated to the
fixed and mobile services for use by public safety. Segments of the
746-764 MHz and 776-794 MHz bands, totaling 6 megahertz and referred to
as the public safety guard bands, were recently auctioned. Cellular-type
systems are prohibited in the guard bands in order to protect public
safety operations against adjacent channel interference, and therefore
this spectrum is not suitable for 3G systems. However, the remaining 30
megahertz of spectrum may be used for 3G services. This spectrum is
planned for auction by March 6, 2001. The WRC results recognize that
some administrations may choose to provide for 3G services in this
spectrum.

3\. **806-960 MHz Band.** WRC 2000 adopted a footnote S5.XXX to the
international table of frequency allocation stating that Administrations
wishing to implement International Mobile Telecommunications-2000
(IMT-2000) may use those parts of the band 806-960 MHz which are
allocated to the mobile service on a primary basis and are used or
planned to be used for mobile systems (see Resolution 224 (WRC-2000)).
The footnote also states that this identification does not preclude the
use of these bands by any application of the services to which they are
allocated and does not establish priority in the Radio Regulations. In
keeping with its principle that existing mobile operators should be free
to evolve to IMT-2000 and beyond as the market demands, any band
available for 1^st^ or 2^nd^ generation systems is also available in the
United States for IMT-2000 or other advanced communications
applications. In the United States, these bands include 806-821 /
851-866 MHz for the Specialized Mobile Radio Services (SMRs) and 824-849
/ 869-894 for the cellular radio service. The Commission\'s planned
Notice of Proposed Rule Making is expected to consider the extent to
which the existing SMR and cellular radio

services may meet the demand for 3G services. The Notice may also
consider parts of the 806 - 960 MHz band that are used by other radio
services.

4\. **1710-1755 MHz Band.** This band is currently allocated on a
primary basis for Federal Government Fixed and Mobile Services. In
addition, radio astronomy services may use the 1718.8-1722.2 MHz band
segment on an unprotected basis. This band is currently used for
Government point-to-point microwave communications, military tactical
radio relay, and airborne telemetry systems. NTIA identified this
spectrum for transfer to the FCC for non-government use, effective in
2004, to satisfy the requirements of the Omnibus Budget Reconciliation
Act of 1993 (OBRA 93). NTIA indicates that, as required under OBRA 93,
all microwave communication facilities in the 1710-1755 MHz band that
are operated by Federal power agencies will continue to operate in the
band and must be protected from interference. A list of exempted Federal
power agency microwave systems, as well as 17 Department of Defense
sites, is presented in Appendix E of the 1995 NTIA Spectrum Report. The
Balanced Budget Act of 1997 (BBA 97) requires this spectrum to be
assigned for commercial use by competitive bidding, with the auction to
commence after January 1, 2001 and to be completed by September 30,
2002.

5\. **1755-1850 MHz Band.** The 1755-1850 MHz band supports four main
Federal functions; space telecommand, tracking and control (TT&C, or
space operations), medium capacity fixed microwave, tactical radio relay
training, and aeronautical mobile applications such as telemetry, video
and target scoring systems. This band is allocated on an exclusive basis
to the Federal Government for fixed and mobile services, and in the
1761-1842 MHz portion, used for space operations. Fixed links are
operated by federal agencies for voice, data, and/or video
communications where commercial service is unavailable, excessively
expensive, or unable to meet required reliability. Applications include
law enforcement, emergency preparedness, supporting the National air
space system, military command and control networks, and control links
for various power, land, water, and electric-power management systems.
Other specified fixed links include video relay, data relay, and timing
distribution signals

Probably the most critical system in the band is the USAF Space Ground
Link Subsystem (SGLS). This system, via Earth-to-space uplinks in the
1761-1842 MHz band, controls the U.S. military satellites, including
telecommunications satellites, intelligence gathering satellites, the
Global Positioning System (GPS) satellite constellation, and satellites
of other Government agencies and U.S. allies. These satellites provide
space-based capabilities that are critical to the execution of all US
military operations. The satellites already in use that are associated
with SGLS are not capable of being modified to operate to accommodate
another frequency and would have to be replaced by new satellites. SGLS
operations must continue to control these on-orbit assets for the
duration of their life spans; which for some may extend beyond 2017.

Air Combat Training (ACT) systems are also used extensively in this band
segment. ACT systems are more complex by the nature of their operations,
as both fixed and aeronautical mobile equipment are used. Air Force and
Navy operate ACT systems. The DoD has stressed that training support
systems such as these are key elements in the military\'s effort to
provide realistic simulation and combat preparedness for pilot training
in a peacetime environment.

Fixed links are operated by federal agencies for voice, data, and/or
video communications where commercial service is unusable. Applications
include law enforcement, emergency preparedness, support for the
National air space system, military command and control networks, and
control links for various power, land, water, and electric-power
management systems. Other specified fixed links include video relay,
data relay, and timing distribution signals.

The Mobile Subscriber Equipment is a multi-band, tactical line-of-sight
microwave radio system, more accurately described as a
\"system-of-systems\", because it is composed of several components
which are fully operational systems. The individual components that make
up the Mobile Subscriber Equipment are dependent upon several portions
of the radio frequency spectrum (e.g., 30-88 MHz, 225-400 MHz, 1350-1850
MHz, and 14.5-15.35 GHz). The inability of any of these components to
operate successfully would result in the failure of the overall Mobile
Subscriber Equipment \"system\". One critical component of Mobile
Subscriber Equipment, the AN/GRC-226(V)2 Radio, is dependent on the
1755-1850 MHz band. It is used to connect Radio Access Units (RAU) in
the AN/TRC-190 series, to the Node Center Switch (AN/TTC-47) of the
network. Operational use plans call for 465 units per Army Corps, giving
a total of 2,325 units for 5 Corps.

6\. **1850-1990 MHz Band (present PCS bands).** RR S5.388, which was
adopted at WRC-92, states that the band 1885-2025 MHz is intended for
use, on a worldwide basis, by administrations wishing to implement
IMT-2000, and that such use does not preclude the use of the band by
other services to which it is allocated. In the United States the band
1850 - 1990 MHz is allocated for the Personal Communications Service
(PCS). The Commission\'s planned Notice of Proposed Rule Making is
expected to consider the extent to which the PCS may meet the demand for
3G services. The 1990 - 2025 MHz band was recently reallocated for
mobile satellite services that are expected to partly satisfy the
satellite component of 3G services.

7\. **2110-2150 MHz Band.** RR S5.388, which was adopted at WRC-92,
states that the band 2110-2200 MHz is intended for use, on a worldwide
basis, by administrations wishing to implement IMT-2000, and that such
use does not preclude the use of the band by other services to which it
is allocated. Domestically, the FCC has identified the 2110-2200 MHz
band for reallocation from the fixed service for new emerging
technologies. The 2165-2200 MHz segment of this band was recently
reallocated for the mobile satellite service. BBA-97 requires
reallocation of the 2110-2150 MHz band and assignment by competitive
bidding by September 30, 2002.

8\. **2500-2690 MHz Band.** The two major services in the 2500-2690 MHz
band are the Multichannel Multipoint Distribution System (MDS), and the
Instructional Television Fixed Service (ITFS)**.** There are currently
thirty-three 6 MHz channels, or 198 MHz of spectrum, allocated to MDS
and ITFS. MDS utilizes two channels in the 2150 to 2160 MHz band. MDS
and ITFS share spectrum in the 2500 to 2686 MHz band.

MDS licensees transmit programming from one or more fixed stations,
which is received by multiple receivers at various locations.
Nation-wide, there are over 2500 licenses for MDS in the band. Licenses
are granted on an area-wide basis, utilizing Basic Trading Areas.
Formerly, MDS licensees used their channels to provide a multichannel
video programming service, so-called \"wireless cable.\" Approximately
one million homes currently receive multichannel video programming
service from MDS/ITFS-based wireless cable systems. However, the MDS
frequencies, located in the 2.1 and 2.5-2.7 GHz bands, also are suited
for the high-speed, high-capacity delivery of broadband access to data,
voice and Internet service. The primary current and future uses of MDS
will be to deliver this access. Rather than being hardwired like the
local telephone companies and local cable systems, MDS uses microwave
frequencies. Like broadcast television, MDS is transmitted from a
broadcast tower, usually located on a mountain or tall building, to
special antennas on residences or businesses throughout a local market.
In the two-way environment, system configurations will be based on a
\"cellularized\" plan, using series of hub and booster stations to link
various main stations to individual subscribers and to relay
transmissions throughout the system.

The other major service in the band is the ITFS, which is regulated
under Part 74, Subpart I of the Commission\'s Rules. ITFS channels are
from 2500 to 2596 MHz, and interleaved with MDS channels above 2644 MHz.
Of the 31, six-megahertz channels in the MDS/ITFS spectrum band, the FCC
licenses twenty of these channels to non-profit educational entities.
ITFS stations are currently utilized for a wide variety of educational
services by schools, hospitals and other educational facilities. In
addition, ITFS unused channels can be used for the same kind of
broadband services discussed above and excess capacity on those channels
may be leased to MDS operators. Partnerships have developed between ITFS
spectrum holders and MDS companies that provide expertise, revenue, and
access to hardware and software to ITFS partners, to better enable them
to build their distance learning programs.

In the last two years, the spectrum has undergone significant changes.
In September 1998, the FCC amended its rules to facilitate the provision
of two-way communication services by MDS and ITFS licensees. When MDS is
used for two-way service, it becomes a viable broadband service delivery
option. Implemented two-way systems can provide advanced, ultra-high
speed, high-capacity broadband data and Internet services to households
and business subscribers, as well as voice service to households in
competition with local exchange carriers. The new rules still
contemplate fixed service, even for two-way operations. The initial
filing window for two-way service occurred from August 14, 2000 until
August 18, 2000 and approximately 3,000 applications were received.

###### Executive Summary {#executive-summary .unnumbered}

The goal of this industry group is to review/update the 3G system
characteristics in order

to ensure that the characteristics utilized for the analysis of sharing
between IMT-2000 and other

systems represent the most accurate information of 3G systems. Attached
below is the table of

characteristics that represent the current systems, much of this
information is the same as found

in ITU-R Recommendation 1457 "Detailed specifications of the radio
interfaces of international

mobile telecommunications-2000 (IMT-2000)". This recommendation in turn
points to the

approved standards that have been developed by the appropriate standards
bodies.

^a^ For some interactions the potential for interference will be
influenced by the degree to which IMT-2000 networks are built out. Table
4 identifies assumptions that will be used in the assessments with
respect to the degree to which US IMT-2000 networks are developed
following the granting of licenses. The levels of aggregate emissions
for a fully mature IMT-2000 environment will be taken from ITU-R 687.2
or other reference material as appropriate.

\[23\] The "TD-CDMA" and "W-CDMA" air interfaces referred to in this
document are standards developed by the 3G Partnership Project (3GPP).
3GPP's official designations for these air interfaces are UTRA-TDD and
UTRA-FDD, respectively. Complete specifications for UTRA-TDD and
UTRA-FDD are available through the 3GPP website at
<http://www.3gpp.org/3G_Specs/3G_Specs.htm>. Series 25 of the
specifications describes the UTRA-TDD and UTRA-FDD radio subsystems. A
specification index is available at
<http://www.3gpp.org/ftp/Information/Databases/Change_Request/>.

\[24\] TD-CDMA differs from the other air interfaces in the table in
that it uses time division duplexing uplink and downlink transmissions
occur in the same spectrum, alternating in time rather than frequency
division duplexing in which uplink and downlink transmissions occur in
distinct frequency blocks. In other respects, such as in-band and
out-of-band emissions levels, modulation formats, etc., it is
substantially similar to the other air interfaces and essentially
identical to W-CDMA. TD-CDMA's coexistence behavior with a given
incumbent government system (or class of systems) can therefore be
assessed through the uplink and downlink coexistence behavior of W-CDMA
with those system(s). It can be well approximated for coexistence
calculations by treating it as a system which has the combined (worst
case from a coexistence perspective) uplink and downlink coexistence
behavior of W-CDMA in a single spectrum block (i.e. by combining the
uplink coexistence behavior of W-CDMA in frequency block "A" with an
incumbent system in block "B", and the downlink coexistence behavior of
W-CDMA in frequency block "A" with an incumbent system in block "B"). At
such time as the FCC may choose to make some or all of the spectrum
under consideration available for commercial use, additional analyses
will be required to develop a sound band plan incorporating allocations
for both FDD and TDD systems. These analyses are already underway in
various segments of the industry including 3GPP \[20\].

# Technical Characteristics of MDS/ITFS Stations {#technical-characteristics-of-mdsitfs-stations .unnumbered}

The technical characteristics of the MDS and ITFS stations can be
summarized as follows. Tables 3-A and 3-B list the characteristics of
stations used for traditional 'one-way' point-to-multipoint ITFS and MDS
(also called MMDS) systems. These systems are used primarily for the
distribution to educational institutions (ITFS systems) of instructional
video programming and for the distribution to paying customers (MDS
systems) of entertainment video programming.

Tables 3-C and 3-D list the characteristics of stations used for two-way
'cellularized' digital MDS and ITFS systems. These systems are used
primarily for wireless internet access and other two-way wireless
communications between fixed points by educational institutions (ITFS
systems) and by paying customers (MDS systems).

# [Abstract]{.underline} {#abstract .unnumbered}

The frequency bands from 1710-1885 MHz and 2500-2690 MHz have been
identified at WRC-2000 as spectrum for consideration in the
implementation of proposed third generation ("3G") mobile services
internationally. However, it was recognized that full utilization of any
identified band might not be possible because of domestic uses in
certain countries. In the US, the bands 2150-2162 and 2500-2690 MHz are
utilized extensively for fixed wireless services commonly know as
Multichannel Multipoint Distribution Services ("MMDS") and Instructional
Television Fixed Services ("ITFS"). These point-to-multipoint services
have been in existence for over 40 years and have numerous transmission
and reception points throughout the country. Historically utilized for
video distribution, these services have undergone important regulatory
changes over the past several years to allow the industry to evolve into
a bi-directional digital high speed Internet access service. The first
regulatory filing period has now concluded and implementation of these
broadband data services on a wide scale basis has begun.

Co-frequency utilization by existing and planned MMDS/ITFS services and
proposed 3G services will not be possible because of unavoidable and
unacceptable interference between the two services. Interference from 3G
services into MMDS/ITFS will be severe because of (1) the sensitivity of
the MMDS/ITFS receivers (both hub and CPE) based on the need to utilize
higher order modulation techniques, (2) the commercial necessity of
utilizing economical receive antennas and the inability to discriminate
the mobile 3G services for interference isolation, (3) the already
compromised interference environment created by existing levels of
co-channel interference between neighboring markets and (4) the need for
high degrees of frequency reuse within urban markets to meet the
expected capacity demands. Likewise, interference from MMDS/ITFS
services into 3G services will be severe because of (1) the use of
omnidirectional mobile receive antennas with no ability to discriminate,
(2) the high power levels of the fixed services at the hub broadcast
over a wide or omnidirectional area, (3) the power levels of the CPE
return path transmissions and (4) the high probability that 3G receivers
will be in close proximity to either MMDS/ITFS hub or CPE sites.

# [MMDS/ITFS System Operation]{.underline} {#mmdsitfs-system-operation .unnumbered}

The architectures for MMDS/ITFS systems vary based on the service
offering, the population of the market and the terrain characteristics
of the market area. Currently there are four basic service offerings:
analog television, digital television, unidirectional digital data and
bi-directional digital data. The architecture that will be utilized in
many second and third tier markets to deliver all of these services is a
single cell or "super cell" configuration. This architecture utilizes a
single transmit site located on a high building or tower to cover a
large area (up to 35 miles in radius.) This architecture may utilize an
omnidirectional or broad beamwidth cardioid antenna with power levels as
high as the FCC rules will allow. In certain markets where terrain or
foliage is severe, repeaters may be used to fill in areas of poor
coverage. These repeaters rebroadcast all channels on the same
frequencies as they are received. Therefore, self-interference can only
be controlled by isolation between service areas created by terrain or
other obstructions.

Cellular architectures are being developed primarily for larger markets
where the expected demand for broadband data can support the increased
costs. This architecture utilizes existing buildings or towers located
in close proximity to potential customer locations with the minimum
height and power necessary to achieve the path reliability throughout
the desired coverage area. Interference is controlled by careful
frequency planning utilizing polarization, sector geometry and receive
antenna isolation.

## *Analog Television* {#analog-television .unnumbered}

A majority of the analog television MMDS/ITFS implementations in the US
utilize an architecture where a single high power transmitter is located
on a tall transmit site in or near a populated area. In urban
environments, this site is usually a tall building or tower in or near
the center of population. The transmit antenna pattern will typically be
omnidirectional or a wide cardioid. In more rural markets the transmit
site may be removed from the population center in order to take
advantage of high terrain feature or an existing tower and a more
directional cardioid antenna would be utilized to concentrate coverage
in the desired area. The maximum EIRP allowed by the FCC is 2000 watts
peak analog power when an omnidirectional transmit antenna is utilized.
Slightly higher power levels may be allowed in certain cases when
cardioid antennas are utilized. Typical EIRP's are in the 100 --1000
watt range. Either horizontal or vertical polarization is allowed.

Receive sites utilize directional antennas of various sizes and gains
dependent upon distance from the transmit site and the quality of the
propagation path to the transmit site. These antennas range in gain from
12 to 27 dBi and vary in size from approximately 0.2 -- 1.2 meters in
diameter. A copy of the antenna patterns for several representative
antennas is attached as Attachment 1. The height of these antennas must
be sufficient to achieve an unobstructed or very nearly unobstructed
propagation path to the transmit site. Because of size and cost, the
smaller antennas are practical for deployment on a broad scale at single
family homes while the large antennas tend to be utilized at
multi-dwelling units or businesses.

Analog television signals require a very high carrier-to-noise ratio
("C/N") at the receive site in order to produce a high quality video
signal. Degradations in received signal strength due to obstructed paths
or interference will very quickly manifest themselves as degraded
picture quality. Current FCC rules require the carrier-to-interference
ratio ("C/I") for incumbent stations to be maintained at 45 dB for
co-channel stations operating in neighboring markets. This level of
protection must be maintained at all unobstructed areas in a protected
service area defined as a 35 mile radius circle around the desired
transmit site. This level of co-channel interference protection will
result in a subjective picture quality of grade 3 based on the ITU/R
Recommendation 500 rating scale. This figure of merit categorizes the
impairment caused by the interference as "slightly annoying."

## *Digital Television* {#digital-television .unnumbered}

Digital television systems utilize the same supercell architecture as
analog television systems with similar technical configurations for the
transmit and receive site equipment. Transmit power limits remain the
same but the EIRP is now referenced to average digital power. The major
difference is in the practical interference protection requirement.
Although the current FCC rules require the same 45 dB co-channel
protection as analog systems, digital systems can tolerate more
interference. The modulation technique employed in digital TV MMDS/ITFS
systems is 64-QAM with forward error correction included. This
modulation allows receivers to tolerate lower C/I than the 45 dB FCC
analog television requirement.

## *Data Transmissions* {#data-transmissions .unnumbered}

Data systems will utilize one of two different architectures depending
on the location of the market, the number of potential subscribers, and
the desired service offerings. In second and third tier markets where
the number of potential subscribers and the desired service offering can
only support a single transmit site, a supercell architecture is
employed. The technical configurations for the downstream transmissions
are the same as an analog or digital television system as described
above with the addition of sectorization at the antenna to improve
frequency reuse and capacity. These systems currently utilize various
modulation techniques including QPSK, 64-QAM, VOFDM and TDMA or CDMA
multiplexing techniques.

Upstream transmissions are accomplished at a subscriber site through a
transverter, typically utilizing the same antenna for transmission as
reception. These antennas have the same gain range as described
previously of 12 to 27 dBi. Many of the transverters and antennas are
built as integrated units. The upstream receive antennas for integrated
units will have typical gains in the 10 to 24 dBi range.

In larger markets where the potential subscriber base can support
multiple cell sites, frequency reuse is necessary to meet the capacity
demands. In order to implement an aggressive frequency reuse plan, a
cellular architecture must be employed. The technical characteristics
will be similar to those discussed previously with downstream and
upstream power levels in the range of 1 -- 100 watts EIRP.

# [Interference Into MMDS/ITFS Systems]{.underline} {#interference-into-mmdsitfs-systems .unnumbered}

## The interference potential from 3G mobile units to the fixed receive sites of an MMDS/ITFS system operating in the same frequency band is real but difficult to predict. These mobile units will be deployed in mass with expected high densities of transmitters. A simulation methodology has to be created in order to estimate the amount of interference power a system could be generating in the area of MMDS/ITFS receive sites. The development of this simulation methodology is beyond the scope of this paper. {#the-interference-potential-from-3g-mobile-units-to-the-fixed-receive-sites-of-an-mmdsitfs-system-operating-in-the-same-frequency-band-is-real-but-difficult-to-predict.-these-mobile-units-will-be-deployed-in-mass-with-expected-high-densities-of-transmitters.-a-simulation-methodology-has-to-be-created-in-order-to-estimate-the-amount-of-interference-power-a-system-could-be-generating-in-the-area-of-mmdsitfs-receive-sites.-the-development-of-this-simulation-methodology-is-beyond-the-scope-of-this-paper. .unnumbered}

## However, predicting the potential for interference from 3G hubs or base stations to MMDS/ITFS receivers is a more manageable task. This potential for interference can best be described by first calculating the predicted level of interference between typical 3G and MMDS/ITFS system configurations and then determining a minimum required separation distance between systems to reduce the predicted interference to manageable levels. MMDS/ITFS receive sites can exist at subscriber locations for downstream transmissions or at hub locations for upstream transmissions. If interference is predicted to be small, then the minimum separation distance will be small and systems can coexist. However, if the predicted interference is severe and the separation distance is predicted to be large, the potential for widespread interference is large and coexistence becomes impossible. {#however-predicting-the-potential-for-interference-from-3g-hubs-or-base-stations-to-mmdsitfs-receivers-is-a-more-manageable-task.-this-potential-for-interference-can-best-be-described-by-first-calculating-the-predicted-level-of-interference-between-typical-3g-and-mmdsitfs-system-configurations-and-then-determining-a-minimum-required-separation-distance-between-systems-to-reduce-the-predicted-interference-to-manageable-levels.-mmdsitfs-receive-sites-can-exist-at-subscriber-locations-for-downstream-transmissions-or-at-hub-locations-for-upstream-transmissions.-if-interference-is-predicted-to-be-small-then-the-minimum-separation-distance-will-be-small-and-systems-can-coexist.-however-if-the-predicted-interference-is-severe-and-the-separation-distance-is-predicted-to-be-large-the-potential-for-widespread-interference-is-large-and-coexistence-becomes-impossible. .unnumbered}

height="3.9965277777777777in"}

The above diagram depicts the potential for interference from a 3G hub
to MMDS/ITFS receive sites. It is assumed from a practical standpoint
that 3G hubs will be distributed around a market area in a way that is
similar to the distribution of current PCS and cellular towers,
resulting in 3G hubs being located in close proximity (i.e., on the
order of 500 - 1000 feet) to many homes and businesses that are
potential subscribers to services offered by MMDS/ITFS systems. As shown
below, however, the calculated minimum tolerable separation distances
for coexistence between 3G hubs and MMDS/ITFS receive locations is on
the order of tens of miles which would result in significant potential
for harmful interference to both analog and digital MMDS/ITFS services.

## *Analog Television Receive Sites* {#analog-television-receive-sites .unnumbered}

Assuming the maximum acceptable level of co-channel interference from a
3G mobile unit or hub to a MMDS/ITFS analog television receive site is
45 dB (C/I), the expected degree of interference to typical system
configurations from one or more 3G hubs can be calculated. This level of
interference protection is currently required by the Commission in the
rules covering MMDS and ITFS operation.

Assume for the first scenario a typical MMDS/ITFS transmit site
configuration with an omnidirectional transmit antenna operating with an
EIRP of 100 watts. The transmit antenna height will be placed at 90
meters AGL. The MMDS/ITFS receive site will use a 12 dBi antenna and
will be located 1 to 35 miles from the transmit site.

The 3G hub is assumed to be operating with 100 watts of average EIRP
spread across a 4.5 MHz bandwidth. The 3G hub is also assumed to be
broadcasting omnidirectional. This assumption may not be reasonable on a
single frequency, however, if all of the frequencies used by the various
3G sectors are co-channel with the MMDS/ITFS frequencies then the study
will represent a composite of all the potential for interference across
the band. The 3G hub is assumed to be located approximately 8 miles away
from the MMDS/ITFS hub. This distance is very conservative and presents
a scenario where 3G services have the best chance of not creating
interference to MMDS/ITFS services.

The results of the study are shown below in Figure 1. The various
colored regions represent different levels of predicted interference. An
area that meets or exceeds the 45 dB requirement appears on the figure
in green. As the study shows, a majority of the 35 mile service area
would receive harmful interference from a single 3G hub. This area of
interference represents approximately 60% of the total MMDS/ITFS
potential service area. In fact, a majority of the interference area
experiences interference levels of 20 dB or greater.

Figure 1 - Interference from a single 3G hub to an MMDS/ITFS service
area.

A minimum separation distance between a 3G transmitter and an MMDS/ITFS
receive site can be calculated using the same assumptions regarding
system operation specified above. Antenna discrimination will not be
considered as there will certainly be locations oriented towards both
the 3G and MMDS hub. The table below shows the required separation
distances in order to reduce the interference shown above to acceptable
levels. As one can see, the required separation distances are calculated
to be in miles, not feet. In fact, all of the distances calculated are
well beyond the radio horizon for normal 4/3 earth curvature. Therefore,
the actual separations will be a function of the radio horizon and the
excess path attenuation generated by terrain and obstruction blockage.
Therefore, coexistence between 3G services and analog television
services is impossible for this scenario.

A similar prediction can be performed for multiple 3G hubs in the same
35 mile radius service area as shown in the Figure 2 below. These hubs
are assumed to be operating on the same frequency as the MMDS/ITFS hub.
This is a reasonable assumption since the hubs are separated by a
relatively large distance. The interference levels become significantly
worse, increasing the interference zone to 80-85% of the available
service area.

##  {#section-16 .unnumbered}

## *Data Transmissions* {#data-transmissions-1 .unnumbered}

Similar calculations can be performed for an MMDS/ITFS high-speed data
system. Assume the same technical characteristics for the system as in
the previous analysis with the exception of lowering the MMDS/ITFS hub
site to 30 meters as might be the case in a cellularized digital data
system. In addition, the service area will be reduced to 15 miles in
radius. Also, the interference protection requirement will change based
on the digital transmission and the modulation technique. The lower
order modulation techniques will tolerate higher levels of interfering
signal than the higher order techniques. Therefore, several different
modulation techniques will be analyzed.

The current technologies being utilized in MMDS/ITFS data transmission
systems utilize various modulation techniques and densities. The highest
order modulation technique currently utilized is 64-QAM. This modulation
technique requires a minimum C/I+N of 22-24dB. Lower order modulation
techniques are possible as well, with a minimum C/I+N requirement of
9-11 dB. These C/I+N values represent theoretical limits and do not
incorporate additional margins for practical equipment operation or
system design margins.

Below is an area wide interference study for MMDS/ITFS data transmission
and a single 3G hub. Again, the service area is significantly reduced
because of the 3G hub interference into CPE receive sites. For the
higher order modulation techniques such as 64-QAM, the area of
unacceptable interference is approximately 60% of the total potential
service area. While lower order modulation techniques would reduce the
percentage somewhat, there would be a severe economic penalty in loss of
capacity.

The table below shows the minimum separation distance requirements for
QPSK through 64-QAM modulation techniques. The same assumptions
regarding power levels were used as in the previous calculations. These
calculations are applicable to supercell or cellular architectures.
Again, the results show the required separation distances to be in
miles, not feet.

Antenna discrimination could improve these conditions at MMDS/ITFS hub
locations. However, the probability that MMDS/ITFS hubs and 3G hubs
would have unobstructed propagation paths to each other is high. In
these situations the ability to use discrimination will be diminished if
not completely eliminated. Therefore, co-frequency operation is again
not feasible between the two services.

Likewise, Figure 4 contains an interference study with multiple 3G hubs
causing interference to a single MMDS/ITFS data reception system. For
higher order modulation densities, the area of interference is
approximately 85% of the total potential service area. Again, the area
of interference could be reduced somewhat by use of lower order
modulation techniques, but at a significant reduction in overall
capacity.

The studies presented in this paper have shown that it is impossible for
3G services to coexist in the same frequency band with MMDS/ITFS fixed
services. The level of co-channel interference from 3G hubs alone is
sufficient to devastate the commercial operation of a MMDS/ITFS system.
If the potential for interference from 3G hubs to MMDS/ITFS hubs and
from 3G mobile units to MMDS/ITFS hubs and CPE's is added into the
equation, the MMDS/ITFS system will be completely unusable. In addition,
the studies in this paper have been extremely conservative with regard
to the operational characteristics of the postulated 3G system. For
example, there typically would be significantly more 3G hubs in an area
than the one to three used in these studies.

# Interference to 3G Systems from ITFS/MDS Systems Sharing the Same Frequencies {#interference-to-3g-systems-from-itfsmds-systems-sharing-the-same-frequencies .unnumbered}

# Introduction and Summary

The purpose of this paper is to analyze the potential for interference
to proposed 3G systems from ITFS/MDS systems sharing the same frequency
of operation. This analysis examines all of the proposed IMT-2000
standards for which interference thresholds were available, based on the
technical specifications set forth in the January 25, 2001 draft Report
of the 3G Characteristics Group of the Industry/Government Informal
Working Group (the "3G Characteristics Report").[^6] The analyses
calculate the required separation distances between proposed 3G base and
mobile units and ITFS/MDS base stations and customer premise units
(response stations). As summarized in Appendix 1, substantial separation
from MDS/ITFS systems is required in order for 3G systems to operate on
a cochannel basis without interference.

# Analysis

Table 1 to the 3G Characteristics Report defines two interference
thresholds for base and mobile 3G units. Threshold 1 is defined by the
received signal level being at sensitivity, with an
interference-to-noise equal to --6 dB, resulting in a 10 percent loss in
the range of the system. The received signal level being 10 dB above the
sensitivity point with the signal-to-noise ratio resulting in a bit
error rate of 10-3 defines threshold 2. These thresholds were not
defined for some categories of 3G technologies and therefore
calculations were not performed in all cases.

Using these interference thresholds, the separation distance between 3G
receivers and ITFS/MDS transmitters necessary to avoid interference can
be calculated. For purposes of the calculations, 3G mobile units were
assumed to utilize a receive antenna with unity gain and hub antennas
were assumed to utilize an antenna with 17 dBi gain.

ITFS/MDS base stations and response stations (subscriber CPE) operate
with a variety of power levels. The maximum power level allowed by the
FCC for stations that utilize an omnidirectional transmit antenna is
2000 watts EIRP in a 6 MHz bandwidth. In those situations where the
station is transmitting an analog signal, this is measured as peak
power, while for digital transmissions it is measured as average power.
Most single cell ITFS/MDS systems, the most prevalent type to date,
operate with EIRP levels between 500 and 2000 watts. Individual cells
within cellular systems will operate with a wider range of power levels,
depending on the number of cells, the service area of the particular
cell, and the propagation characteristics of the market. Therefore,
three power levels, 2000, 500 and 100 watts EIRP, were considered in the
analysis.

ITFS/MDS response stations (the CPE) also operate with a variety of
power levels and bandwidths. The maximum power level allowed by the FCC
is 2000 watts in a 6 MHz bandwidth. As the bandwidth is reduced or
increased, the maximum power level of the upstream transmitter is
adjusted based on equivalent power spectral density. For purposes of
this analysis, a typical power level of 668 watts EIRP in a 2 MHz
bandwidth was utilized.

Attached as Appendix 1 is a table showing the separation distance
required between an MDS/ITFS transmitter and each proposed 3G
technology. These calculations assume an unobstructed electrical path to
the radio horizon limit of 161 kms. Calculations resulting in separation
distances beyond the radio horizon were limited to 161 kms. Also, the
worst case geometry resulting in bore sighted conditions between the
transmit and receive antenna was assumed. No cross polarization
discrimination was considered since ITFS/MDS systems use both horizontal
and vertical polarization liberally to maintain isolation with adjacent
markets. In addition, these studies did not consider the effects of
multiple ITFS/MDS radiators within a market. Note however that in all
markets there will inevitably be multiple response stations (CPE)
operating simultaneously and that in multicell markets, multiple
downstream transmission may be occurring on the same frequency at the
same time. A more detailed analysis accumulating the signal levels
generated by these multiple radiators was not conducted in light of the
compelling results when even a single radiator is considered.

# Interference to 3G Mobile Receivers

As the results show, interference threshold 1 for mobile 3G receivers is
only met when the receiver is isolated from the ITFS/MDS base or CPE
transmitters using the radio horizon for separation. The required
separation distance is always beyond the radio horizon and is therefore
for purposes of Appendix 1 is limited to the defined radio horizon
distance of 161 kms.

Likewise, for a majority of the cases analyzed based on interference
threshold 2 the separation requirement for mobile 3G receivers remains
at or very close to the radio horizon. However, when the ITFS/MDS base
station power is lowered to 100 watts EIRP, the separation distance is
reduced to 66 kms for CDMA 2000 1X. Note, however that this power level
of 100 watts is only likely to be employed by MDS/ITFS multicell
systems. Therefore, as a practical matter it will be necessary to
consider the accumulation of signals from multiple MDS/ITFS cells and
greater separation will be required to protect the 3G system.

# Interference to 3G Base Station Receivers

The results show for all cases at interference threshold 1 that the
level of interference into 3G hubs requires separation distances equal
to the radio horizon. When the interference threshold is relaxed to
threshold 2, certain 3G technologies will allow a 3G base station to
operate within 102 kms or a 100 watt MDS/ITFS base station.

# Conclusions

These calculations prove conclusively that cochannel frequency sharing
between 3G and ITFS/MDS systems is not a practical solution. MDS/ITFS
systems are operating in most markets across the country, and the
required separation distances would only permit 3G systems to operate
without interference in the most rural areas.

RADIO SERVICE DEFINITIONS

**DEFINITIONS --**

**allocation (of a frequency band):**  Entry in the Table of Frequency
Allocations of a given frequency band for the purpose of its use by one
or more terrestrial or space radiocommunication services or the radio
astronomy service under specified conditions. This term shall also be
applied to the frequency band concerned.

**primary service:** a service the name of which is printed in
"capitals" (example: FIXED). Stations of a primary service take
precident over stations of a secondary service.

**secondary service**: a service the name of which is printed in "normal
characters" (example: Mobile). Stations of a secondary service:

> a\) shall not cause harmful interference to stations of primary
> services to which frequencies are already assigned or to which
> frequencies may be assigned at a later date;
>
> b\) cannot claim protection from harmful interference from stations of
> a primary service to which frequencies are already assigned or may be
> assigned at a later date;
>
> c\) can claim protection, however, from harmful interference from
> stations of the same or other secondary service(s) to which
> frequencies may be assigned at a later date.

**SELECTED RADIO SERVICES --**

**aeronautical fixed service**: A radiocommunication service between
specified fixed points provided primarily for the safety of air
navigation and for the regular, efficient and economical operation of
air transport. A station in this service is an aeronautical fixed
station. \[*See* 47 C.F.R. § 87.5\]

**broadcasting-satellite service**:  A radiocommunication service in
which signals transmitted or retransmitted by space stations are
intended for direct reception by the general public. In the
broadcasting-satellite service, the term "direct reception" shall
encompass both individual reception and community reception.

**earth exploration-satellite service**:  A radiocommunication service
between earth stations and one or more space stations, which may include
links between space stations, in which:

-- information relating to the characteristics of the Earth and its
natural phenomena, including data relating to the state of the
environment, is obtained from active sensors or passive sensors on Earth
satellites;

-- similar information is collected from airborne or Earth-based
platforms;

-- such information may be distributed to earth stations within the
system concerned;

-- platform interrogation may be included.

This service may also include feeder links necessary for its operation.

For fixed operations, a "Link" is defined as a unique
frequency/polarization combination between a specific transmitter site
and specific receiver site. Any number of links can be on a path. (A
"Path" is defined as the pairing of a transmit site with an associated
receive site.)

[Map Legend]{.underline}:

> Solid Lines represents the path between a fixed transmitter site and a
> fixed receiver site with up to four passive repeater sites if any are
> present.

[^1]: ^\*\*^ UWC-136 consists of three components: enhancements to the
    30 kHz channels (designated as 136+) for advanced voice and data
    capabilities, a 200 kHz carrier component for high speed data (384
    kbit/s) accommodating high mobility (designated as 136HS Outdoor),
    and a 1.6 MHz carrier component for very high speed data (2 Mbit/s)
    in low mobility applications (designated as 136HS Indoor). The
    combined result constitutes the IMT-2000 Radio Interface referred to
    as UWC-136.

[^6]: There is no reason to believe that the results would be
    significantly different for the cases where interference thresholds
    were not included in the 3G Characteristics Report.

[^7]: For fixed operations, a "Link" is defined as a unique
    frequency/polarization combination between a specific transmitter
    site and specific receiver site. Any number of links can be on a
    path. (A "Path" is defined as the pairing of a transmit site with an
    associated receive site.)

[^8]: For mobile operations (as well as temporary fixed operation), a
    "Link" is defined as a unique frequency/polarization combination for
    an authorized mobile antenna. The area of operation for a mobile
    operation can be specified as a point radius or a descriptive area
    (*e.g.,* State of Florida or country-wide). Furthermore, each link
    could have an unspecified number of mobile units associated the
    license.

[^9]: For fixed-satellites, a "Link" is defined as a unique
    frequency/polarization combination for an antenna at an earth
    station which are not tied to a specific space station. It should
    also be noted that in many cases, the antennas can support
    communications with one or more transponders aboard a space station
    within a specified band segment. The details of the transponder
    interfaces are not recorded in the station license. In most cases,
    an earth station is authorized to communication with all domestic
    spaces stations. Although the licensee is required to provide
    information on the total number of VSAT stations to be deployed,
    that number is not necessarily what has be truly been deployed.
