1.3. Base Station Units
The ASWipLL Base Station interfaces between the subscriber sites and the service
provider's backbone, providing subscribers with high-speed data, Internet, and VoIP
services.
The ASWipLL system provides various devices (some optional) for the Base Station
site. The implementation of these devices depends on the desired network (e.g.
point-to-point radio link), number of outdoor radios and power source at the Base
Station, and required synchronization type (i.e. by GPS).
Figure 1-2 shows a fully populated ASWipLL Base Station at maximum
configuration (24 BSRs, 4 BSDUs, 1 BSPS, and a GPS).
