3. Views in regard to agenda item 1.9
UMTS Forum has actively participated in, and also contributed to, the preparations of the ITU-R for WRC-07 Agenda Item 1.9. With 115 million IMT-2000/UMTS subscribers, UMTS Forum is of the view that the band 2500-2690 MHz will be extremely important for the extension of capacity of IMT-2000/UMTS networks to offer evolving services in the next few years to come. The current ITU-R regulations of power flux density (PFD) limits applicable to space services will lead to significant interference into IMT-2000/UMTS systems considerably above the appropriate sharing criteria. It is therefore necessary to tighten these limits to protect terrestrial IMT-2000/UMTS systems, allowing for the cost effective developments of IMT-2000/UMTS and IMT-Advanced. Therefore UMTS Forum urges WRC-07 under agenda item 1.9 to review the regulatory provisions applicable to space services in the band 2500-2690 MHz in order to protect future terrestrial IMT-2000/UMTS services in this band.
