2 Product 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.
