1.3.1. 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 the following models:
! BSR with a built-in antenna
! BSR with one N-type port for connecting an optional third-party external
antenna
! BSR with two N-type ports for connecting two optional third-party external
antennas for dual antenna diversity
For Base Stations consisting of multiple BSRs, the BSRs are powered, and interface
with the provider’s backbone by the ASWipLL Base Station Distribution Unit
(BSDU). 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).
1.3.2. Point-to-Point Radio (PPR)
The PPR device is similar to the BSR, but implemented in a point-to-point radio
configuration, providing wireless communication with a single remote subscriber
ASWipLL radio unit (i.e. SPR or IDR).
