General Information
The
Peninsula Engineering Solutions 1900 MHz Network Repeater
, hereafter referred to as the
PES1900Gi NR (or
the repeater)
, is a bi-directional, on-frequency, over-the-air RF repeater that
extends the coverage of PCS base stations. This repeater is appropriate for outdoor and indoor
applications including in-building coverage and distributed antenna systems. The PES1900Gi NR is
optimized for GSM networks.
The repeater receives signals from a Cell Site BTS/RBS and retransmits them to a mobile or portable
telephone; likewise, the repeater receives signals from a mobile or portable telephone and
retransmits them to the Cell Site BTS/RBS.
Repeaters significantly improve coverage in areas with weak signal reception or transmission. The
power amplifier ratings, the antenna system, and the donor cell channel configuration determine the
Effective Radiated Power (ERP) output of the installed repeater.
The PES1900Gi NR is designed for indoor or outdoor installation and can be either wall- or pole-
mounted. The unit’s compact cabinet simplifies installation, while it’s aesthetically acceptable design
allows it to be easily zoned in many locations.
The repeater only requires initialization of the gain and channel to be on the air. In addition, as a field-
replaceable unit, no component-level repair is necessary.
The assembly consists of a transceiver assembly, power amplifier assemblies, diplexers, power
supplies and microcontrollers. All assemblies are mounted on a heatsink and enclosed in a sealed,
aluminum, weather-tight cabinet.
During normal operation, the cabinet housing remains closed. Access to power and data
transmission connections is provided through the connection ports located on the bottom of the
repeater. Install repeaters and associated hardware in locations suitable for adequate reception of
signals from the Donor Cell Site and for effective retransmission of these signals to mobiles and
portables.
The Network Management System (NMS) version of the PES1900Gi NR is equipped with an optional
GSM modem, which is mounted on the interior of the cabinet front door. This modem operates with
RepeaterNet NMS for monitoring a network of repeaters. For more information, see RepeaterNet
Craft for the PES1900Gi NR.
In addition to the PES1900Gi NR assembly, Peninsula Engineering Solutions offers accessory
equipment: antennas, mounting hardware, coaxial cable, and BUPS (Back-up Power Systems).
Typical antennas include:
⇒
Parabolic reflector
⇒
Corner reflector
⇒
Circular, linear, directional co-linear
⇒
Cross or slant polarization
⇒
Log periodic array
⇒
Yagi
Antenna usage depends upon the intended coverage area and other project parameters.
