Development of Wireless Access Technologies

Narrowband Wireless Access

Broadband Wireless Access

Broadband Wireless Access

Supporting Trunkingservice

• 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

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.
