1 INTRODUCTION
This manual describes the installation and setup procedures for Cobham Wireless SMR 700 800 high power,
Class A digital, public safety signal boosters.
All booster models relevant to this manual operate in the same manner will be referred to as the ‘booster’,
where any differences in the software configuration procedure or parameters will be addressed in the
relevant section.
It features up to 24 DSP based, software-controlled, variable bandwidth filters that are user-programmable
across the 700 and 800 MHz bands. All public safety technologies are supported.
For each filter, the user can specify the start and stop frequencies to reduce the installation time of the
signal booster and enable a very wide range of filters selection. Every configuration parameter, including
filter tuning and selection, can be controlled via web based management. The patented Cobham Wireless’
digital RF filter enables simple initial setup for any channel plan and if necessary, allows some basic
reconfiguration due to re-banding.
The SALC - Smart ALC algorithm will reduce the gain to protect the signal booster from oscillation. When the
gain cannot be reduced anymore a shut-down mechanism will be triggered.
The signal booster protects against degradation of the system’s sensitivity and coverage. This is
implemented by the inbuilt AGC per-channel (filter) feature, which permits equalization of the channel levels
for uniform coverage.
This product meets the rigid requirements as defined by the NFPA and International Fire Code
developmental organizations. The amplifier is painted a Fire Life Safety Red, meets NEMA4 compliance for
hose down, and provides all Alarming outputs as defined by NFPA 2010, Chapter 24 including system and
antenna failures. The signal booster is a DC fed unit.
NOTE: Optionally, an external battery charger unit is available as well. The charger is connected to the AC
and includes a circuit to charge external batteries with all the dry contact alarms as defined in the NFPA
standard: AC failure, Charger failure and Low battery.
