## DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE[^1]

**Agenda Item 1.11: *to review sharing criteria and regulatory
provisions for protection of terrestrial services in particular
terrestrial television broadcasting services, in the band 620 -- 790 MHz
from BSS networks and systems, in accordance with Resolution 545
(WRC-03)***

**Background:**

Under footnote No.**5.311**, the band 620-790 MHz may be used for
assignments to television stations using frequency modulation in the BSS
(GSO or non-GSO). Since this band is extensively used by terrestrial
applications, Recommendation **705 (WARC-79)** includes, among other
things, satellite pfd limits needed to protect the terrestrial services,
in particular, the terrestrial television broadcasting service that uses
this band extensively in all three Regions.. It should also be noted
that there are allocations to the fixed and mobile services in some
regions in this band that also need to be addressed. In particular, some
Region 2 administrations added their names to footnote No.**5.293**
which allocates the band to the fixed and mobile services on a primary
basis in several Region 2 countries.

In Region 2 the 620-790 MHz band is used extensively by free-to-air TV
systems. As a result of this extensive use of the 620-790MHz band,
Region 2 Administrations have not made allowances for external
interference in the deployment of their terrestrial TV systems or in the
development of their TV allotment plans or in the development of other
fixed and mobile services and therefore, there are no excess margins
which could have been used to accommodate additional interference from
systems in the BSS.

WRC-03 adopted a freeze on the processing of BSS satellite filings in
the band until the next WRC as per a new Resolution **545 (WRC-03)** and
suspended the application of No.**5.311** and Recommendation **705**
**(WARC-79)** until that date. The Resolution was acceptable to all
parties with the understanding:

1)  it allows for studies to continue on the appropriate protection
    levels for the terrestrial broadcasting service (BS) to be
    determined;

2)  it does not impact the Regional Planning Conference (RRC-06 and
    Region 2 is not affected) for these services;

3)  it places a moratorium on further deployments of BSS networks in
    these bands until such studies are complete.

This proposal suppresses **No. 5.311** and Res. **545** to ensure the
complete protection of the current and future usage of the broadcast,
mobile, and fixed services in the 620-790 MHz band from interference
from new broadcast satellite operations in this same band. In addition,
the proposal adopts a new Resolution that would address grandfathering
of the existing Russian BSS networks operating in the band. This
proposal suppresses the BSS allocation and only allows the grandfathered
networks to continue to operate. This proposal aligns with the Method B
to resolve this agenda item in the Draft CPM Report to WRC-07.

As a consequence, Rec. **705**, "Criteria to be applied for frequency
sharing between the broadcasting-satellite service and the terrestrial
broadcasting service in the band 620-790 MHz", is deleted.

**Proposals:**

**USA/ / 1 SUP 5.311**

**5.311** Within the frequency band 620-790 MHz, assignments may be made
to television stations using frequency modulation in the
broadcasting-satellite service subject to agreement between the
administrations concerned and those having services, operating in
accordance with the Table, which may be affected (see Resolutions **33
(Rev.WRC‑03)** and **507 (Rev.WRC‑03)**). Such stations shall not
produce a power flux-density in excess of the value --129 dB(W/m^2^) for
angles of arrival less than 20º (see Recommendation **705**) within
the territories of other countries without the consent of the
administrations of those countries. Resolution **545 (WRC‑03)**
applies.     (WRC-**03**)

**Reasons**: Operators of TV broadcasting services not allocated any
additional interference margins for the protection of terrestrial TV
broadcasting and therefore any additional interference from BSS will
place undue constraints on the existing and planned services TV
broadcast services.

**USA/ / 2 SUP** Recommendation **705**

**RECOMMENDATION 705**

Criteria to be applied for frequency sharing between the\
broadcasting-satellite service and the terrestrial broadcasting\
service in the band 620-790 MHz

**Reasons**: Because the allocation to BSS is suppressed under this
proposal, there is no need for Recommendation 705 to be maintained.

**USA/ / 3 ADD** Resolution **\[620-790MHz\]**

**Draft Resolution \[620-790MHz\]**

**Use of frequency band 620-790 MHz for existing assignments to
broadcasting-satellite service**

The World Radiocommunication Conference 2007 (WRC-07)

considering

a.  that Regional Radiocommunication Conference ,Geneva 2006 ( RRC-06)
    has adopted an Agreement and associated Plans for digital
    terrestrial broadcasting for Region 1, except Mongolia, and the
    Islamic Republic of Iran in the frequency bands 174-230 MHz and
    470-862 MHz,

b.  that the above-mentioned Conference, in its Resolution 1
    **(RRC-06)** invited WRC-07 ,when considering Agenda Item 1.11,
    ensure that the Plan ( s) established shall be effectively protected
    , *inter alia*, from the BSS GSO and non-GSO broadcasting satellite
    networks/systems operating or to planned be operated in frequency
    band 620-790 MHz.

c.  that many administrations have extensive infrastructure for the
    transmission and reception of analogue and digital television
    signals between 620 MHz and 790 MHz;

d\) that, as a result of the transition from analog to digital
terrestrial television broadcasting, some countries are making the band
698-806 MHz available for applications in the mobile service;

recognizing

a\) that in accordance with provision No. **5.311**, adopted at a
previous WARC several decades ago, two assignments to "Statsionar t" and
"Statsionar t2 BSS networks in the band 620-790 were notified, brought
into use and the their date of bringing into use confirmed before the
end of the World Radiocommunication Conference (Geneva, 2003) (WRC‑03),

b\) that, according to the records of the Bureau, there has been no
complaint of any harmful interference to or request for claiming
protection for these two assignments from the terrestrial television
systems of any administration

*further recognizing*

a)  that there is a need to authorize these two assignments to continue
    their operation in providing the broadcasting satellite service to
    their defined service area

b)  that this Conference has suppressed the provision No. **5.311**, in
    the light of the protection requirements of the terrestrial
    television systems and other terrestrial systems mentioned in the
    *considerings* above

> *resolves*

that the frequency assignments of the Statsionar t" and "Statsionar t2"
BSS networks, within the frequency band 620 -- 790 MHz, shall be
recorded in the Master Register with favorable finding.

instructs the Director of the Radiocommunication Bureau

to implement this Resolution.

**Reasons**: Recognizes the needs of the existing BSS systems using the
band, this proposed Resolution allows them to continue operating.

**USA/ / 4 SUP** Resolution **545**

RESOLUTION **545** (WRC-03)

Technical and regulatory procedure relating to the
broadcasting-satellite service networks operating in the 620-790 MHz
band

**Reasons**: Because the allocation to BSS is suppressed under this
proposal, there is no need for Resolution 545 to be maintained.
