10/22: WiMAX

WiMAX Business

1. WiMAX 802.16e is not substitute of 3G.
3G spans from physical layer to applications while 802.16e is MAC.

2. WiMAX is part of a bigger infrastructure.
Still needs networking and transport control to support applications.

3. WiMAX highlights state of the art of computer networking while 3G and beyond is state of the art of telecommunications.

4. WiMAX points a new direction of cost down and quality of service. Maybe it is time of paradigm shift from telecom (3G and B3G) to computer networking (IEEE802). Remember 802.16 is basically non contention-based while 802.3 and 802.11 are all contention-based.
