Outline Introduction WiMAX Standards WIMAX Architecture WiMAX Applications Conclusion
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)
WiMAX What is WiMAX? Worldwide Interoperability for Microwave Access – Brand name for IEEE 802.16 standards
WiMax Standards 802.16a 802.16d-2004 802.16e Date Completed December 2001 June 2004 December 2005 Spectrum 10-66 GHz < 11 GHz < 6 GHz Operation LOS Non-LOS Non-LOS and Mobile Data Rate 32 Mbps Up to 75 Mbps

WiMax Spectrum Unlicensed 5 GHz: bands between 5.25 and 5.85 GHz. Licensed 2.5 GHz: bands between 2.5 GHz and 2.6GHz.
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.
