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).
