2 Product Overview
2.1 Product Information
The CS40-734834-00D-A0 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 the downlink and 80 dB nominal gain the uplink, gain
can be adjusted over a range from 60(50) dB to 90(80) 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.
The key features of this product are seamless interface to the 700/800 5W Composite DAS Ready
