In ITU-R, Mobile BWA related business, mainly Land Mobile Service Excluding IMT-2000, and Amateur and Amateur-satellite Service are under administration of Working Party 5A. Working Party 5A has published Recommendation ITU-R M.1801, which refers to Radio Interface Standards for Broadband Wireless Access Systems Including Mobile and Nomadic Applications in the Mobile Service Operating below 6 GHz, to recommend the use of several mobile BWA systems. The recommended systems, of which the specifications are put together by other recommending organizations, are categorized in the following five groups:
Radio-LAN (Recommendation ITU R M.1450：IEEE 802.11,ETSI BRAN HIPERLAN,ARIB HiSWANa)
IMT-2000(Recommendation ITU R M.1457：CDMA Direct Spread, CDMA Multi-Carrier, CDMA TDD, TDMA Single-Carrier, FDMA/TDMA）
Harmonized IEEE and ETSI radio interface standards(IEEE 802.16, ETSI HiperMAN)
ATIS WTSC radio interface standards(T1.723-2002, ATIS-0700001.2004, ATIS-0700004.2005,T1.716/7-2000(R2004))
XGP(A-GN4.00-01-TS)

This recommendation, approved in March 2007 and published in June 2007, is now the most authoritative recommendation concerning mobile BWA. Of the five groups, the 1st and the 2nd ones can be referred in the earlier published ITU-R documents as Radio-LAN and IMT-2000 technologies. Hence, the remaining three groups are approved this time as genuine BWA technologies. In the remaining groups, there are six technologies such as WiMAX、I-CDMA (Internet code division multiple access)、MCSB (multi-carrier synchronous beam forming), HC-SDMA(high capacity-spatial division multiple access, i-Burst), broadband direct sequence CDMA and XGP(eXtended Global Platform).

Besides, WP5A has also published Report ITU-R M.2116, which refers to Characteristics of Broadband Wireless Access Systems Operating in the Land Mobile Service for Use in Sharing Studies in September 2007 as another relevant document to mobile BWA.

At the current stage, WP5A is compiling the supplementary document of Land Mobile Handbook Volume 5 BWA. Land Mobile Handbook is a guidebook written for developing countries in selecting, planning and designing new systems. It is expected that the above mentioned systems including XGP, as well as IMT-2000 is to be compiled in the guidebook.

The sub-working group 4 of the Spectrum Working Group (WG-SPEC) in AWF（Asia Pacific Telecommunity Wireless Forum） is in charge of study and discussions about BWA. The BWA report titled “CHARACTERISTICS AND REQUIREMENTS FOR BROADBAND WIRELESS ACCESS SYSTEMS “ had been compiled in the sub-working group 4. And this report formally got approved in the plenary meeting of 7th AWF meeting in September 2009.
