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 (depending on SDA model) that provides the SPR with DC power, lightening
protection, and Ethernet (10Base-T and/or 100Base-T )connectivity to the
subscriber’s PCs/network (up to four PCs depending on SDA model). The SPR
connects to the SDA by a CAT-5 cable.
The SPR is typically mounted on the subscriber's roof or external wall; the SDA is
installed inside the subscriber's premises.
The SPR is available in the following models:
! SPR with Standard Gain: includes a built-in antenna 15-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.
Note: The SDA can also be installed at a base station that has only one BSR.
This SDA replaces the need for the BSDU, and provides power and
connectivity to the single BSR.
