Figure 25 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 26 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 MAX-207HW2R and
the base station are controlled by the base station. The MAX-207HW2R 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.
