2. Introduction
2.1. Purpose
This manual contains information and procedures for the operation of the Commscope
Public Safety Repeaters PSR 700/800 MHz 0.5/2W Class A and Class B. The purpose
of this document is to provide a step-by-step procedure to help experienced
technicians or engineers install and commission an in-building wireless enhancement
system using Commscope repeater. Follow the instructions in this guide to minimize
risks associated with modifying a live system and preclude service interruptions. This
document assumes the technician or engineer understands the basic principles and
functionality involved with repeater and in-building systems. This guide has been
written to address the practical concerns of the installer.
2.2. PSR 700/800 MHz 0.5/2W
This pick-up repeater comes in two variants, one is a digital, channelized Class A or
Class B repeater and the second is an analogue Class B repeater. Both can be used
stand-alone or in combination with an Era™ system.
They are designed to cover the 700 and 800 MHz public safety bands and can be used
to establish a wireless connection between a BTS and a passive or active DAS. Via
feature keys, this repeater can be configured as a single- or dual-band version with an
output power of 0.5 W or 2 W per band. With its battery backup support (only available
in combination with a UPS), NEMA 4x housing, dry alarm contacts and its integrated
oscillation detection and healing mechanism a fully NFPA 72 and IFC compliance can
be guaranteed.
The implemented time-slot-based muting functionality prevents desensitization of the
BTS by switching off UL channels without traffic. The class A supports up to 32
channels in a range between 12.5 kHz and 10 MHz, where every channel can be muted
while no traffic is active. A detailed filter description can be found in chapter 2.2.3
Digital Filter. With the class B variant, the operator can choose between 3, 10 and 18
MHz pass band bandwidths, where every pass band can be muted while no traffic is
active.
