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.
Figure 30 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 31 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 Device and the
base station are controlled by the base station. The WiMAX Device follows the
base station’s configuration.
