Completing the 4G Vision: Gateways for Mobile WiMAX

WiMAX is a set of specifications created by the WiMAX Forum and based on standards developed by the IEEE 802.16 Working Group (WG). There are two standards of note here. The first is IEEE 802.16-2004, sometimes called 802.16d, which specifies a common air interface for fixed (both ends stationary) microwave equipment. But since the high-growth market opportunity for wireless of any form today is in mobile systems, the 802.16 WG subsequently issued 802.16e-2005, which specifies a mobile broadband technology.
