New ITU-R Recommendation on fixed BWA
ITU-R Study Group 9 (Working Party 9B) has
developed a draft new Recommendation on BWA in
the fixed service (ITU-R Doc. 9/51), whose
specifications are based on the standards agreed
at recognized standards development organizations
(SDOs).

Draft new Recommendation ITU-R F.Doc. 9/51
Radio interface standards for broadband wireless
access systems in the fixed service operating
below 66 GHz
The Recommendation identifies specific radio
interface standards for BWA systems in the FS,
addressing profiles for the recommended
interoperability standards. It provides
references to the standards for interoperability
between BWA systems. The interoperability
standards referenced in the Recommendation
include the following specifications system
profiles PHY layer parameters, i.e.
channelization, modulation scheme, data rates
MAC layer messages and header fields conformance
testing methods
BWA standards harmonized for
interoperability(below 11 GHz)

New ITU-R Recommendation on mobile BWA
ITU-R Study Group 8 (Working Party 8A) is
developing a draft new Recommendation on BWA in
the mobile service operating below 6 GHz (ITU-R
Doc. 8A/202, An.15), whose specifications are
based on the standards agreed at recognized
standards development organizations (SDOs).

characteristics of air interfaces for global
broadband satellite systems
Specifications for a generic satellite network
architecture and protocol structures, and for
satellite earth stations air interfaces based
on the following standards

ETSI EN 301 790 V.1.3.1 Interactive Channel for
Satellite Distribution Systems ETSI BSM/RSM-A

BWA ITU World Radiocommunication Conference
2007 (WRC-07)
Agenda Item 1.4To consider frequency-related
matters for the future development of IMT-2000
and systems beyond IMT-2000 taking into account
the results of ITU-R studies in accordance with
Resolution 228 (Rev.WRC-03) Agenda Item
1.19To consider the results of the ITU-R
studies regarding spectrum requirement for global
broadband satellite systems in order to identify
possible global harmonized FSS frequency bands
for the use of Internet applications, and
consider the appropriate regulatory/technical
provisions, taking also into account No. 5.516B
of the Radio Regulations.

Summary

• Broadband Wireless Access systems
• are important media in access networks
• will operate in different environments and in
  variousfrequency bands
• will be better developed under efficient
  cooperation between SDOs and ITU-R.
