Essentials of WiMAX with Emphasis on Mobile Standard (IT119-99-0)

SynopsisMobile WiMMAX or 802.16e, is an amendment to IEEE 802.16 ("Air Interface for Fixed Broadband Wireless Access Systems"), or WiMAX standard, as modified by IEEE Standards 802.16a, 802.16-2004 and 802.16c. The 802.16e covers Physical and Medium Access Control Layers for Combined Fixed and Mobile Operation in Licensed Bands. The emerging 802.16e standard will specify new mobile air interfaces for wireless broadband. 802.16e will add mobility in the 2 to 6 GHz licensed bands. This course provides an overview of 802.16 or WiMAX for the important concepts with an emphasis in the mobility and handover aspects of 802.16e.
