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.
