Wimax Networks

الملخص

New data services are increasing demand on a data rate in communication systems, the emerging technology, which allows high speed broadband wireless access, is Wimax. It is often thought that Wimax is one unique technology when in fact it is a trade name for a group of Institute of Electrical & Electronics Engineers (IEEE) wireless standards. IEEE 802.16 is an emerging wireless MAN technology. The IEEE 802.16 standard contains the specification of Physical (PHY) and Medium Access Control (MAC) layer for Broadband Wireless Access (BWA). In this paper, the development of IEEE 802.16 is presented, Wimax network architecture, physical layer fundamentals, medium access control operations, access types and finally some application is mentioned also.
