WiMAX
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless networking
standard, which provides high-bandwidth, wide-range wireless service across wireless Metropolitan
Area Networks (MANs). Huawei is a member of the WiMAX Forum, the industry group dedicated to
promoting and certifying interoperability of wireless broadband products.
In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or a
subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to maintain
connectivity while switching their connection from one base station to another base station
(handover) while subscriber stations use other standards that do not have this capability (IEEE
802.16-2004, for example). The following figure shows an MS-equipped notebook computer MS1
moving from base station BS1s coverage area and connecting to BS2.
