Specified items Protocol stack Scope of BWA Standardization Application Higher Layer ITU-T Recommendations － TCP ・Network routing ・Mobility management Network layer(IP) ・Send-receive flow control ・ARQ control ・QoS control DLC Sub-layer Data Link Layer MAC Sub-layer ・Medium access control 　・Error detection & correction 　・Radio frequency arrangement 　・Modulation/Demodulation 　・Transmission bit rate Physical Layer （PHY） ITU-R ・Necessary bandwidth ・Frequency sharing criteria Recommendations TCP : Transmission Control Protocol IP : Internet Protocol MAC : Medium Access Control DLC : Data Link Control

  6. 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). New ITU-R Recommendation on fixed BWA Referenced specificationsfor the radio interface in the Recommendation: PHY Layer MAC Layer IEEE Std. 802.16-2004 IEEE 802.16 HiperMAN ETSI TS 102 177 ETSI TS 102 178 ETSI BRAN HiperAccess ETSI TS 101 999 ETSI TS 102 000 Note: These specifications in this Recommendation are available electronically through the website.

  7. Radio interface standards for broadband wireless access systems in the fixed service operating below 66 GHz Draft new Recommendation ITU-R F.[Doc.9/51] 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 forinteroperability 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)

  8. 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). New ITU-R Recommendation on mobile BWA Referenced specificationsfor the radio interface in the Recommendation: Draft IEEE 802.16e

  9. Recommendation ITU-R S.1709: Technical characteristics of air interfaces for global broadband satellite systems ITU-R Recommendation on global satellite BWA 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:Air interface specifications for global broadband communications between earth stations and regenerative satellites TIA‑1008: Internet Protocol over Satellite (IPoS)

  10. BWA & ITU World Radiocommunication Conference 2007(WRC-07) Agenda Item 1.4:To 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 1.19:To 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”.

  11. ITU & BWA • Radiocommunications • Frequency spectrum (harmonization)  WRC & RR • Radio interface specifications  ITU-R Recommendation • Collaboration with external organizations  IEEE 802.16 WG, ETSI Project BRAN, … • Strategy & Policy • Workshops & publications  Promoting Broadband, The Birth of Broadband & country case studies • Telecom development • Report on Broadband Technologies (ITU-D Q.20/2) • Seminars on BWA (2004: Rep. Korea, 2005: Brazil & China) Visit: http://www.itu.int/ITU-R/study-groups/was/

  12. 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.
