1.9 to review the technical, operational and regulatory provisions
applicable to the use of the band 2 500-2 690 MHz by space services in
order to facilitate sharing with current and future terrestrial services
without placing undue constraint on the services to which the band is
allocated

Introduction

Technical and regulatory studies conducted under WRC-03 Agenda item 1.34
on sharing between the BBS (sound) systems and terrestrial systems in
the band 2 605-2 655 MHz, showed that the technical and regulatory
provisions currently applied to space services allocated in the
2 500-2 690 MHz do not provide the required protection to current and
future terrestrial systems in the band 2 500-2 690 MHz. That is the
reason why WRC-07 Agenda item 1.9 was proposed in this context. The
scope of Agenda item 1.9 is limited to the review of the technical,
operational and regulatory provisions applicable to the space stations
transmitting in the band 2 500-2 690 MHz with a view to protecting earth
stations in the fixed and mobile services.

The studies conducted under Agenda item 1.9 have shown that the current
regulatory situation applicable to space services allocated in the band
2 500-2 690 MHz does not provide the required protection to current and
future terrestrial systems in the band 2 500-2 690 MHz. In particular,
the current pfd limits applicable to space services will cause
interference to IMT-2000 systems that will significantly exceed the
suitable sharing criteria. Consequently, it is necessary to impose more
stringent pfd limits with a view to protecting terrestrial systems,
including IMT-2000, and continuing the development of IMT-2000 and
IMT-advanced in the band 2 500-2 690 MHz.

A stringent limit regulatory regime, based on the specification of a
power flux-density mask in Article 21, is the regulatory regime that
would ensure the long-term protection of terrestrial systems in the band
2 500-2 690 MHz from satellite interference. Such a regime would also
provide a long-term perspective for space systems that would be
introduced in a clearly defined framework.

Proposals

The Arab States propose:

ARB/39A8/1

1\) to use the method of imposing power flux-density (pfd) limits
(Method A in the CPM Report) to all space services, except BSS (sound),
in the band 2 500-2 690 MHz, in order to ensure the protection of
current and future terrestrial services;

ARB/39A8/2

2\) to avoid imposing undue constraints on the terrestrial services in
the band 2 520-2 670 MHz that include allocations to the BSS (sound);

ARB/39A8/3

3\) to specify the new pfd values in Article 21 in order to ensure the
protection of terrestrial services from space services, and to insert
the necessary modifications into Article 21, Section V, Table 21-4;

4\) to introduce the following modifications to RR Article 5.
