WiMAX Mobility - 802.16e

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.
