Figure 27 WiMax: Mobile Station
WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber
stations and mobile stations to local base stations. Numerous subscriber stations
and mobile stations connect to the network through a single base station (BS), as
in the following figure.
Figure 28 WiMAX: Multiple Mobile Stations
A base station's coverage area can extend over many hundreds of meters, even
under poor conditions. A base station provides network access to subscriber
stations and mobile stations, and communicates with other base stations.
The radio frequency and bandwidth of the link between the WiMAX Modem and the
base station are controlled by the base station. The WiMAX Modem follows the
base station’s configuration.
Authentication
When authenticating a user, the base station uses a third-party RADIUS or
Diameter server known as an AAA (Authentication, Authorization and Accounting)
server to authenticate the mobile or subscriber stations.
