WiFi vs WiMax

Since I’m avid reader of PinoyTechBlog , this leads me to google WiFi vs WiMax and I found this comparison in this forum

Operating spectrum:
WiFi - 2.4GHZ or 5.8GHZ
WiMax - 2GHZ - 66GHZ
Maximun Throughput
WiFi - 2MPBS - 54MPBS
WiMax - 70 MPBS
Distance
WiFi - 200 yards
WiMax - Several miles
Transport protocol
WiFi - EthernetWiMax - TCP, IP, ATM
Equipment costs
WiFi - few hundred dollars
WiMax - several thousand dollars

WiFi is designed for hotspot internet access.
WiMax is designed for fixed broad wireless access over a relatively longer distances.WiMax competes with DSL and Cable for fixed broadband internet access. WiFi does not have a similar direct competitor.

FYI:
WiFi - Short for ‘wireless fidelity’. A term for certain types of wireless local area networks (WLAN) that use specifications conforming to IEEE 802.11b

WiMAX - an acronym that stands for Worldwide Interoperability for Microwave Access, is a certification mark for products that pass conformity and interoperability tests for the IEEE 802.16 standards. IEEE 802.16 is working group number 16 of IEEE 802, specialising in point-to-multipoint broadband wireless access
