6.1.1 What You Need to Know
The following terms and concepts may help as you read through this chapter.
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). ZyXEL 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
