Wireless Access
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. 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. Next Steps / Actions
Wireless Access Tech. supporting trunking service
Continuing pre-standard research on current and emerging technologies.
Find the possibility of integrating different technologies.
