2. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-GRSC9-19 2 Highlight of Current Activities Wireless telecommunication technical committee of CCSA (CCSA TC5) now focuses on the following wireless access technologies research and standardization. Wireless Access Tech. Wireless Access Tech. supporting trunking service WLAN UWB WLAN and mobile access interworking TC5 WG3 (Wireless Access WG) TC5 WG9 (TD&WCDMA&LTE WG)

3. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-GRSC9-19 3 Development of Wireless Access Technologies Narrowband Wireless Access Broadband Broadband Supporting Trunking service Service: fixed voice Mainly applied in rural areas Limited market and less users Service: data, voice Supporting high speed data access Service: data, voice, trunking service Mainly targets private networks and industrial users

4. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-GRSC9-19 4 Challenges Broadband wireless access is not competitive with 3G and enhanced 3G technology. Since Basic telecom operators prefer deploying 3G cellular networks than building BWA networks, it’s better to enhance BWA technology and applied them to private network. Now there exists several technologies supporting trunking services, such as SCDMA based, LTE based, TETRA and other technologies. Potential market of private network is limited, therefore it’s not beneficial to develop multiple standards.

5. Halifax, 31 Oct – 3 Nov 2011ICT Accessibility For All GSC16-GRSC9-19 5 Next Steps / Actions Continuing pre-standard research on current and emerging technologies. Find the possibility of integrating different technologies. Wireless Access Tech. supporting trunking service Wireless Access Technology Research on new wireless access technology.
