802.16e is an amendment to IEEE Standard 802.16 ("Air Interface for Fixed Broadband Wireless Access Systems") 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 802.16e.
