1.3.1. Base Station Site
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 Base Station is comprised of the following units (some optional):
Base Station Radio (BSR) :
The BSR is an outdoor radio unit, typically mounted on a pole or wall, involved
in providing a wireless link between the Base Station and subscribers. The
standard BSR provides 60-degree radio coverage, serving up to 126 subscribers
in a sector.
The BSR is available in various models that either provide built-in antennas or
N-type ports for attaching a third-party antenna(s) for increasing radio coverage
or providing dual antenna diversity.
For Base Stations consisting of multiple BSRs, the BSRs connect to the
ASWipLL Base Station Distribution Unit (BSDU), which provides the interface
to the provider’s backbone, and power. For a Base Station consisting of a single
BSR, the BSR is typically powered and connected to the provider’s backbone by
the ASWipLL Subscriber Data Adapter (SDA).
Point-to-Point Radio (PPR):
The PPR is similar to the BSR, but implemented in a point-to-point radio
application, providing wireless communication with a single remote subscriber
(i.e. ASWipLL Subscriber Premises Radio).
Base Station Distribution Unit (BSDU) :
The BSDU is an Ethernet switch implemented at Base Stations consisting of
multiple BSRs. The BSDU provides 100Base-T interface between the BSRs and
the provider's backbone. The BSDU is also responsible for providing BSRs with
–48 VDC power supply and frequency hop synchronization for multiple BSDUs
and BSRs.
