The Role of IEEE802. 16e Mobile WiMAX

A recent technology for the next generation (fourth generation [4 G]) of mobile broadbandnetworks is commonly known as Worldwide Interoperabilityfor Microwave Access ( WiMAX) that is designed to provide high bandwidth over long range transmission. IEEE 802.16e mobile WiMAXis accountable for the job of establishing interoperabilityand conformance between products. This paper provides an brief overview of mobile WiMAX, its features and challenges on the wireless local and Metripolitan Area Network (MAN) standards IEEE 802.16 and IEEE 802.16e.
