2.1 Product Information
The PS71090-P8 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 cov erage
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.
