3. Introduction Definition of Communications
Communication is the process of transferring information from a sender to a receiver with the use of a medium.
The evolution of communication
Old
The emerge of electricity (telegraph) in 1844.
Telephone 1876.
Applications telephone networks (PBX, modems, fax, ISDN, Leased line, Fram relay)
Wireless communication (Mobile phone, Satellite, Bluetooth, Wi-Fi -, WiMAX)

Licensed 2.5 GHz: bands between 2.5 GHz and 2.6GHz.

11. WIMAX Architecture WIMAX system consists of
WiMAX Tower (Base Station):
Similar in concept to a cell-phone tower – a single WiMAX BS can provide coverage to a very large area.
WiMAX Receiver (Subscriber Station)
The receiver could be a small box or PC card, or they could be built into a laptop.
