1. DOCUMENT #:GSC15-GRSC8-03 FOR:Presentation or Information SOURCE:CCSA AGENDA ITEM:4.1 CONTACT(S):dangmeimei@mail.ritt.com.cn Standardization activities on Broadband Wireless Access in CCSA CCSA Global Standards Collaboration (GSC) GSC-15

2. Research scope of CCSA TC5 WG3 Wireless access group of wireless telecommunication technical committee of CCSA (CCSA TC5 WG3) was setup in 2003. More than 40 members,8 observers.

3. Evolution of SCDMA system Narrowband SCDMA Narrowband SCDMA McWill （ Broadband SCDMA ） McWill ( Mutimedia trunking system) McWill ( Mutimedia trunking system)  Service: fixed voice  Frequency: 400MHz/1800MHz  Mainly applied in rural areas  Service: data, voice  Frequency: 1800MHz  Supporting high speed data access  Service: data, voice, trunking service  Application: business users SCDMA is a wireless access technology developed by Beijing Xinwei Telecom Technology Incorporation.

4. Timeline of SCDMA standardization Broadband SCDMA Narrowband SCDMA 2004 2006 20072008 2009 SCDMA multimedia trunking system 2010 Project started Standards for approval

5. Efforts on International BWA Standardization  In November 2009, CCSA put forwarded McWill(Multi- carrier Wireless information Local Loop) technology to ITU-R.  McWill was finally accepted as one BWA air interface of ITU-R M.1801 recommendation at ITU-R WP5A session.  Key Technical Characteristics TDD/code-spread OFDMA(CS-OFDMA) channel bandwidth of multiple of 1 MHz up to 5 MHz. multiple antenna techniques QPSK, 8-PSK, 16-QAM and 64-QAM for both uplink and downlink

6.  Wireless ad-hoc network  Zigbee Next Steps/Actions Development of Standards  Air interface, Equipment Specification, test method of new generation of SCDMA.  UWB air interface specification  WLAN air interface  Other technologies Research Cooperation  Liaison with IEEE 802  Cooperate with other SDOs
