Diff on Wifi & WiMAX

Wimax is Worldwide Interoperability for Microwave Access. The different from Wifi is the bandwith and coverage. The WiMAX specification provides symmetrical bandwidth over many kilometers and range with stronger encryption and typically less interference. Wi-Fi is short range (approximately 10's of meters) has WEP or WPA encryption and suffers from interference as in metropolitan areas where there are many users. The benefit of Wimax over wifi are: 1. Wi-Fi Hotspots are typically backhauled over ADSL in most coffee shops therefore Wi-Fi access is typically highly contended and has poor upload speeds between the router and the internet. 2. It provides connectivity between network endpoints without the need for direct line of sight in favourable circumstances.

I think these are only bandwidth. Just like others. but with some more hi-fi technique & relaibility,
