Motive to Converge 3G and WiFi
Voice + data + multimedia
/
Licensed & unlicensed spectrum
Converged services Hybrid Networks with mobility Widen broadband footprint Lower services delivery cost Exploit unlicensed service areas
Benefits for Operator & Users
Mobile Operator Mobile Operator
Full set of services — with complete mobility Lower capex while improving indoor coverage
Residence
Leverage existing investment with evolution to IMS All services, all devices, unique identify from one service provider
Enterprise
Lower cost on campus mobile communications – voice and data
Role of Hybrid Access Networks
Solves in-building broadband wireless coverage problem Reduces 3G deployment costs Facilitates new service offerings, implemented at IP layer
PSTN
Provides easy migration path among access technologies – today WiFi, tomorrow WiMax Enables true convergence Independence of access networks Common services across different access networks Integration with existing billing and OSS systems
