record of your purchase.
The general safety information in this guideline applies to both operations 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 Signal Booster is designed to operate at 110VAC @ 1.02A 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

call your dealer or Westell’s technical support line at 1.877.844.4274.
CAUTION
Turn the Signal Booster power off when connecting or disconnecting cables.
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi.
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 3.75
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 use may result in significant
forfeiture penalties, including penalties in excess of $100,000 for each continuing
violation.
FCC Warning Labels
The following labels will appear on the PS71090 Signal Booster in accordance with the FCC:
The PS71090 Signal Booster 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 or Panel antenna. Internal antennas are
typically omnidirectional, although various other types may be used, depending on the coverage
application. The Signal Booster 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 90 dB nominal gain on both the uplink and downlink, gain can be adjusted
over a range from 60 dB to 90 dB in 1 dB steps.
The Signal Booster is controlled using a computer connected to the RJ45 Female Network Connector
labeled ‘GUI’. There are also LED indicators to indicate alarm status, OSC and power. Refer to Figure
4-1.

2.4 Optional Accessories
A complete line of accessories is available from Westell. Check with your Westell distributor for any
additional items needed. Some products that are suitable for most in-building needs are listed in
Table 2-2.
• The PS71090 Signal Booster is designed for indoor use only.
• The PS71090 Signal Booster must be installed in a vertical orientation (i.e. Connectors on the
bottom of the unit).
• Inadequate isolation between the outside and inside antennas may cause regenerative
feedback in the system.
This feedback can cause the amplifier to emit a continuous signal at maximum
Amplitude, and, in some cases, interfere with normal operation of the donor site.
Careful consideration of the layout and placement of the system is imperative to
minimize this possibility and to minimize the amount of signal leaking from the
Building.
• Do not disassemble the Signal Booster.
DANGER!
• Refer to the 1.3 Safety Guidelines section for proper antenna selection and
installation. To avoid serious injury, death and/or damage to the Signal
Booster, do not install donor or server antennas near overhead power lines or
high power components. Allow enough distance so that falling antennas
would not come in contact with those components.
• Electric shock may occur if the Signal Booster is installed in close proximity to
water.
WARNING!
• Amplifier or handset damage may occur if a handset is connected directly to
the Signal Booster or to the coax that leads to the Signal Booster.
• The PS71090 Signal Booster must be connected to ground for protection.
• We recommend that installers do not wear jewelry or metal accessories when
installing this Signal Booster.
• Do not place cables or tools that may damage the Signal Booster in close
proximity to it.
• Check the installation site for hazardous conditions such as water-covered
floors or badly worn or damaged cables prior to installation.
• Lifespan and performance of the Signal Booster may be reduced if the unit is
• Close proximity to the donor or server antennas with the Signal
Booster in operation may expose users or installers to RF fields that
exceed FCC limits for human exposure.
• Turn power to the Signal Booster off when connecting or disconnecting
cables.
5.2 Donor Antenna Installation Guidelines
• Accurately determine the azimuth to the donor site. Obtain the donor site information and
approval from the service provider/carrier.
• Ensure that the radiation path to the donor site is unobstructed.
• Mount the donor antenna at or toward the edge of the roof, in the direction of the donor
site. Avoid having the RF signal from the donor pass above the location(s) of the service
antennas. Normally, the service antennas are installed behind and below the donor antenna,
as viewed from above. This approach helps avoid interference and feedback to and from the
service antennas.
• Normally, mounting the donor antenna higher will allow a less obstructed path to the donor
site. However, in high traffic metro areas, avoid mounting the donor antenna higher than
necessary, as the quality of the donor signal may become less stable and it is more likely to
encounter adjacent channel interference.
• When possible, shield the rear of a donor antenna by locating it so that any HVAC units
and/or penthouse structures are behind the antenna, relative to the donor cell site location.
5.3 Indoor Antenna Installation Guidelines
• Use omnidirectional antennas (see section 2.4. Optional Accessories) indoors and locate
them centrally with respect to the intended coverage area to minimize signal leakage to the
outside. Only use directional antennas indoors in special cases when higher gain and
directionality would be helpful and RF exposure limits will not be exceeded.
• To avoid Signal Booster uplink overload and gain limiting, mount the indoor antennas away
from areas where mobile subscribers frequently use their phones / radios, such as desks or
dispatch areas.
• To determine the quantity and locations of indoor antennas, measure Received Signal
Strength Indication (RSSI) using DM Tool software to determine areas of weak signals. These
are the approximate areas where indoor antennas may be needed.
• Be aware that the signal from an indoor antenna, in most cases, can be expected to
penetrate approximately two standard sheet rock walls to reach users. If the signal must
travel through more than two walls, or if the walls are made of materials other than sheet
rock, it may be necessary to split the available signal and add more antennas.
• Check all cables for shorts and opens. Verify that there are no cables with loose or poor
connections. RF leakage could cause oscillation to occur under some conditions.
• If the rooftop antenna (donor antenna) is directional, check it for proper alignment along
the calculated compass heading. Typically, the directional antenna would be aimed at the
same site that your handset uses, but that may not always be the case.
• If cables and alignment are acceptable, and a problem persists, use a spectrum analyzer to
examine the signal environment in which the unit is operating. The existence of strong
adjacent channel signals within the frequency band(s) can cause the AGC to reduce the
amplifier’s gain or cause alarms. In some cases, additional filtering or attenuation may be
required to reject these unwanted signals. In some instances, the donor antenna can be
reoriented horizontally to place the interference source in an antenna pattern null.
5.6 Controlling the Signal Booster
Control and monitoring the Signal Booster requires that a properly configured computer with Westell
PS71090 control software installed is connected via an Ethernet cable, such as the one shown in
Figure 5-2A. Connect the Ethernet cable from the Network Interface port of a computer to the GUI
port on the bottom end panel of the Signal Booster.
Use the provided Alarm Relay Serial Cable to connect the PS71090 Public Safety Signal Booster to the
