######## Introduction

In this document, the United States presents supplemental proposals
under WRC-07 agenda item 1.9. These proposals are necessary to address
transitional measures associated with the new power flux density (pfd)
limits contained in CITEL IAP/1.9/3 and IAP/1.9/5 in CCP.II-RADIO/doc.
1408/07 rev.2. Transitional measures are needed to determine when the
new pfd limits are applied and to which satellite network filings. This
issue was addressed at the Conference Preparatory Meeting (CPM). The
proposal is a variation of the Option 2 concerning the transitional and
implementation arrangements found in section 3/1.9/5.5 of the CPM text.
Specifically, changes are proposed to add a footnote to the relevant pfd
limits in Article 21 (those proposed in IAP/1.9/3 of CCP.II-RADIO/doc.
1408/07 rev.2) to address which satellite systems are subject to the new
limits, and which are subject to the old regime. Changes are also
proposed to Article 59 of the Radio Regulations to refer to new
Resolution 2500 Transition (WRC-07) to state when the changes to the
Radio Regulations made under this agenda item will come into force.
These proposals also address changes to the footnotes in Article 5 that
are applicable to the 2500-2690 MHz band.

The previous PCC.II meeting also considered the transitional measures
associated with the new power flux density (pfd) limits in the 2500-2690
MHz band. The outcome of that consideration is presented in IAP/1.9/4 of
CCP.II-RADIO/doc. 1408/07 rev.2. This contribution proposes adjustment
to the IAP/1.9/4 in such a way that does not alter the overall
transitional measures approach while affirming that this approach is
appropriate only in the 2500-2690 MHz band.

**Proposed additional and modifications text for CITEL IAP on agenda
item 1.9:**

**Background information**

(*Editorial note:* Additional background text to be added at the end of
the Background text in CCP.II-RADIO/doc. 1408/07 Rev. 2)

**Transitional Measures**

In order to ensure protection of terrestrial services in the 2500-2690
MHz band, it is necessary to address transitional measures associated
with the revised pfd limits in Article 21. It is necessary to define the
date of entry into force of the new power limits, as well as the revised
footnotes to Article 5, and to define to which satellite network filings
the Bureau will apply the new pfd limits in its processing of filings
under Articles 9 and 11 of the Radio Regulations. This proposal is a
variation on Option 2 concerning the transitional and implementation
arrangements found in section 3/1.9/5.5 of the CPM Report.

IAP/1.9/ 3 [(*Editorial note:* The IAP/1.9/ 3 of CCP.II-RADIO/doc.
1408/07 rev.2, is presented here for reference purposes only. No
modifications are proposed to the IAP/1.9/ 3 of CCP.II-RADIO/doc.

RESOLUTION 2500_Transition (WRC-07)

Transitional measures for application of Article 21 provisions

in the band 2500-2690 MHz

The World Radiocommunication Conference (Geneva, 2007),

considering

a)  that WRC-07 revised the limits of power flux-density from space
    stations in Article **21**, Table **21-4** for the band 2500-2690
    MHz;

b)  that use of the bands 2500-2690 MHz in Region 2 and 2500-2535 MHz
    and 2655-2690 MHz in Region 3 by the fixed satellite-service is
    limited to national and regional systems, subject to agreement
    obtained under No. **9.21** (see No. **5.415** and No. **5.2.1**);

    c.  that in the band 2520-2670 MHz, the broadcasting-satellite
        service is limited to national and regional systems, subject to
        agreement obtained under No. **9.21** (see No. **5.416** and
        No. **5.2.1**);

    d.  that in the band 2520-2535 MHz, the mobile-satellite service
        (space-to-Earth) is limited to within national boundaries,
        subject to agreement obtained under No. **9.21** and application
        of the provisions of No. **9.11A** (see No. **5.403**);

    e.  that, in No. 5.384A, the 2 500-2 690 MHz band is identified for
        use by administrations wishing to implement International Mobile
        Telecommunications-2000 (IMT-2000) in accordance with Resolution
        223 **(WRC-2000)**;

    f.  that due to the unique national and regional limitations applied
        to certain space services and the identification for use by
        administrations wishing to implement IMT‑2000, it is
        advantageous to apply the revised Article **21**, Table **21-4**
        limits in the band 2500-2690 MHz at an early date,

recognizing

1.  that in the 2 500-2 690 MHz band, several administrations in all
    three Regions implemented or plan to implement advanced wireless
    terrestrial services exclusively,

2.  that in the 2 500-2 690 MHz band, some administrations deployed or
    plan to deploy satellite networks,

3.  that in the cases of national or regional satellite systems
    described in *considerings b), c),* and *d)* , the service area can
    include the territories of administrations only with the explicit
    agreement from those administrations;

4.  that in frequency bands below 3 GHz, the satellite networks
    inherently have a wide geographic coverage that may extend beyond
    the intended service area;

5.  that in the band 2 500-2 690 MHz, the ITU-R concluded, on the basis
    of certain assumptions, that it is not technically feasible to
    operate mobile-satellite service systems and terrestrial services
    systems on co-frequency basis in the same geographical area;

```{=html}
<!-- -->
```
6.  that applying power flux density limits to the band 2500-2690 MHz
    alleviates the uncertainty of the coordination process;

7.  that expedited transition to the revised power flux-density limits
    in the band 2 500-2 690 MHz adopted by WRC-07 would facilitate
    deployment of commercially viable advanced wireless networks and is
    necessary due to the unique national and regional limitations
    applied to certain space services,

resolves

1 that the power flux-density at the Earth's surface produced by
emissions from space stations in the 2500-2690 MHz band by the
fixed-satellite service, the 2520-2670 MHz band by the
broadcasting-satellite service, and the 2500-2516.5 MHz band by the
radiodetermination-satellite service for which complete notification
information has been received by the Radiocommunication Bureau before 17
November 2007 and the notified date of bringing into use is prior to 31
December 2008 shall not exceed the following values:

--152 dB(W/m^2^) for \< []{.underline}5°

--152 + 0.75(δ -- 5) dB(W/m^2^) for 5° ≤ δ ≤ 25°

--137 dB(W/m^2^) for δ \> []{.underline}25°

in any 4 kHz band, where δ is the angle of arrival above the horizontal
plane and the limits in Table **21-4** do not apply,

1.  that the coordination thresholds in Table **5-2** of Annex 1 to
    Appendix **5** of the Radio Regulations (Edition of 2004), in
    conjunction with the applicable provisions of Articles **9** and
    **11** of the Radio Regulations associated with No. **9.11A**, shall
    apply to mobile-satellite service systems and networks in the band 2
    500-2 535 MHz for which complete notification information has been
    received by the Radiocommunication Bureau before 17 November 2007
    and the notified date of bringing into use is before 31 December
    2008 and the limits in Table 21-4 do not apply,

instructs the Radiocommunication Bureau

as of the end of WRC‑07, to observe the above *resolves* when examining
frequency assignment notices received from administrations.

**Reasons:** To address transitional measures associated with revised
power flux-density limits in Article **21** for the 2500-2690 MHz band.
