Wimax is short for World Wide Interoperability for Microwave Access
It operates like Wi-fi using wireless radio signal and covers a bigger WAN than Wi-fi and greater speeds. It is mean’t to replace cable DSL connection and provide broad band to remote inaccessible areas where there is no cable networks.
Covers an area of 3000 square miles.
Wimax system consists of two parts;
Wimax tower similar to a cell-phone tower providing coverage as big as 3000 square miles.
Wimax receiver- receiver and an antenna could be a small box or PCMCIA card or they could be built into a laptop the way wi-fi is today
Wimax provides two forms of wireless service.
Non-line-of-sight. Where a small antenna on your pc connects to a wimax tower using low frequency radio signal (2GHz-11GHz) similar to wifi.
Line-of-sight,(back haul). Where a fixed dish antenna points straight at the wimax tower from a roof top or pole.
This radio connection is stronger and more stable so its able to send a lot of data.
