Actually Wimax is not envisioned as a local service, but this does not mean it cannot be used as such. Currently most wimax companies are producing CPE's. I have not seen and 802.16 wireless routers yet. I am sure we will see some eventually. Battery use will probably not be a problem since it is the base statation that is doing the transmitting.

It will operate to provide a high density, self-healing network that replaces conventional fiber networks. It has special emphasis for reaching remote areas like Alaska where AT&T ran trials. Typical operation is on 3.5 GHz worldwide with the exception of the U.S. where that frequency is blocked by military restrictions. Current implementations in the U.S. use 2.5GHz. There are other frequencies available. WiMax certainly doesn't want to crowd into the 2.4 GHz range currently used by microwave ovens, wireless phones, Bluetooth, and 802.11. AT&T feels that WiMax would have prevented loss of communications in New York during 9/11 had a network been in place across Manhattan. The local CPE (Customer Premises Equipment) that I saw would link directly to the 802.16 network and had a direct RJ-45 connection to hook into a customer network. You could easily hook right into your wireless network. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Brinkley Harrell http://www.fusemeister.com -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
