1General Information
1.1 Document Purpose and Intended Users
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 Westell’s PS51080 Public Safety 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.
1.2 Application
Use this guide whenever there is a need to add enhanced signal capability to an existing system or when a repeater
is included in a new installation.
1.2.1 Product Registration Information
The serial number is located on the label on the panel near the power connectors. Record this number in Figure 1-1.
Retain this manual, along with proof of purchase, to serve as a permanent record of your purchase.

1.3 Safety Guidelines
The general safety information in this guideline applies to both operating and service personnel. Specific warnings
and cautions are located in the applicable manual sections, but may not appear in this summary. Failure to comply
with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture,
and intended use of equipment. Westell assumes no liability for the customer’s failure to comply with these
requirements:
Grounding: This repeater is designed to operate at 110VAC @ 0.5A maximum current and must always be operated
with the ground wire properly connected.
Explosive atmospheres: To avoid explosion or fire, do not operate this product in the presence of flammable gases
or fumes.
Lightning danger: Do not install or adjust this unit during an electrical storm.
No user-serviceable parts are inside the unit. Hazardous voltages are present when the cover is removed. Opening
the chassis will void your warranty. If you suspect a malfunction with this product, call your dealer or Westell’s technical
support line at 1.877.844.4274.
CAUTION
Turn the repeater power off when connecting or disconnecting cables.

1.3.1 Important Safety Information
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. The outdoor
antenna used for the purpose of communicating to the wireless infrastructure is limited to 14 dBi gain, or any
combination of gain and loss that equals 14 dB at input. Each antenna must be positioned to observe minimum
separation requirements from all users and bystanders .
The following guidelines must be used when considering separation distances:
Indoor antennas must be placed so that under normal conditions, personnel cannot come within 20 cm (~8
in) of any inside antenna. Adhering to this minimum separation will ensure that the employee or bystander
cannot exceed RF exposures beyond the maximum permissible limit as defined by FCC Regulations section
1.1310 Limits for general population/uncontrolled exposure.
Outdoor antenna must be positioned so that under normal conditions , personnel cannot approach closer
than 120 cm (~4 ft.). A directional antenna having a maximum gain of 14 dBi is used, and precautions
should be taken to prevent personnel from routinely passing through the main radiation beam at a distance
closer than specified.
1.4 FCC Part 90 Signal Boosters
WARNING!
THIS IS A 90.219 CLASS B DEVICE
This is not a consumer device. It is designed for installation by FCC licensees and
qualified installers. You must have an FCC license or express consent of an FCC
Licensee to operate this device. You must register class B signal boosters (as defined
in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration. Unauthorized

2Product Overview
2.1 Product Information
The PS51080 repeater was developed for use in enclosed structures where signals from local public safety towers to
operate mobile units is poor or unavailable. Adequate signal strength must be available outside the structure as a
prerequisite to achieving in-building coverage. The device is connected to an external antenna, normally located on
a roof, and to one or more internal antennas placed strategically throughout the area where wireless service is desired.
The external antenna is typically directional, such as a Yagi antenna. Internal antennas are typically omnidirectional,
although various other types may be used, depending on the coverage application. The repeater amplifies both the
uplink (mobile to base) and downlink (base to mobile) signals, thus facilitating communications to and from the
intended wireless infrastructure.
With a maximum total of 80 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range
from 50 dB to 80 dB in 1 dB steps.
The repeater is controlled using a computer connected to the 8P8C/RJ45 Female Network Connector labeled ‘GUI’.
There are also LED indicators to indicate alarm status, OSC and power. Refer to Figure 4-1.
2.2 Product Features
Easy installation
Light and small
One body type
Control using a Windows-based Graphical User Interface (GUI) and accessed by connecting a laptop or
desktop computer to the 8P8C/RJ45 Female Network Connector labeled ‘GUI’
User gain control
Automatic level control
Automatic shutdown function
Oscillation protection
Overdrive protection
Under/over voltage protection
Fault protection
Alarm notification
