The ITU-R study group on terrestrial services will approve one...

arrangements for public protection and disaster relief radiocommunication systems in UHF bands in accordance with the WRC-03 resolution on public protection and disaster relief. The recommendation provides guidance on frequency arrangements for public protection and disaster relief radiocommunication in certain regions in some of the bands below 1 GHz that are identified in the resolution, it said. The recommendation currently addresses arrangements in the ranges 746-806 MHz and 806-869 MHz in the Americas, 380-470 MHz in certain African, European and ex-Soviet countries and 806-824/851-869 MHz in some Asia-Pacific countries, in accordance with ITU-R and WRC resolutions. Revisions, including new fixed service system parameters, were made to the recommendation on considerations in the development of criteria for sharing between the fixed and other services. A recommendation on global circulation of IMT-2000 terminals was revised so it doesn’t deal with the IMT satellite component. Another draft revision addresses generic unwanted emissions characteristics of mobile and base stations using IMT-2000 terrestrial radio interfaces. Changes were also made to radio frequency channel arrangements for fixed wireless systems operating in the 7, 10, 11, 18 and 23 GHz bands, and for systems of the fixed service operating in the 38 GHz band. Changes were made to channel arrangements for medium- and high-capacity digital fixed wireless systems operating in the upper 6 GHz band, it said, referring to 6425 to 7125 MHz. Changes were made to channel arrangements for radio-relay systems operating in the 14 GHz band, it said.
