8.1. Overview
The SPR receives and transmits data from and to the base station. The SPR connects
to the subscriber’s network through the SDA. The SDA is an Ethernet hub/LAN
switch that provides the SPR with DC power, lightening protection, and Ethernet
connectivity to the subscriber’s PCs/network. The SPR connects to the SDA by a
CAT-5e cable.
The SDA provides 10/100BaseT connectivity (depending on the SDA model) to the
subscriber’s PCs or network (up to four PCs depending on SDA model).
The SPR is typically mounted on the subscriber's roof or external wall The SDA is
located inside the subscriber's premises.
The SPR is available in three models:
! SPR with Standard Gain: includes a built-in antenna 15/16-dBi antenna gain,
covering an area of 23 degrees
! SPR with High-Gain Antenna: includes a built-in antenna with an 18-dBi
antenna gain, covering 15 degrees.
! SPR with external antenna: includes an N-type connector port for attaching a
third-party external antenna.
Figure 8-1 displays a typical setup of the SPR and SDA at the subscriber's premises.

This SDA replaces the need for the BSDU, and provides power and
connectivity to the single BSR.
