Abstract

Wi-MAX stands for the Worldwide Interoperability for Microwave Access and is also known as the IEEE 802.16 wireless metropolitan area network. IEEE 802.16e WIMAX (Worldwide interoperable Microwave Access) is the upcoming wireless system which can offer high speed voice, video and data service up to the customer end. In 1998, a working group named 802.16 was formed by the Institute of Electrical and Electronics Engineers (IEEE), and their responsibility is to develop the specifications of broadband wireless access technology. IEEE specifies the different modulation techniques which should be used in WIMAX namely QPSK, 8-QAM, 16QAM and 64 QAM.
