Amazingly, somehow WiMax (802.16) can create a hotspot that stretches

I can only guess that they must turn up the power big time.
Won't this burn up the batteries on client laptops?
Also, couldn't they have just called it a derivative of 802.11 like
802.11f for "fast" ???? Sheesh!
WiMax is not designed as a replacement for 802.11 service. WiMax is
designed to provide a more viable mesh architecture for primary network
infrastructure. 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.
