20dBm Cell Phone Signal Boosters 900MHz Band Selective Digital
Repeater
Cell Phone Signal Booster Description:
Greetwin Band Selective 900MHz Repeater is designed for indoor or outdoor
applications, adjustable bandwidth to suit the operator needs. The
Repeater is ideal for use in large inbuilding situations such as
tunnels, shopping malls, carpark, and in outdoor applications for
extending rural coverage.
The digital 900MHz band selective repeater is an alternative to
traditional signal amplifiers in the standards GSM900. It works in
several systems and sub-bands simultaneously.
Has the ability to select a channel. Thanks to this function, you
can get more accurate signal amplification, high quality of
incoming voice calls and internet data that do not interfere with
neighboring base stations.

Number of sub-bands:
Digital 900MHz, 4 sub-bands, each 0.2 ~ 10MHz, configurable and
adjustable within the frequency range of 900MHz
Band Selective 900MHz repeater is designed to amplify the mobile
900MHz signal. The device guarantees uninterrupted calls and high
speed of downloading mobile data throughout the zone.
The digital repeater has a range filtering system, so it can
amplify the signal only of certain mobile network operators and
block other networks.
The repeater is also equipped with OMT / OMC remote control and
monitoring system allowing to configure and control the device
operation remotely via PC or wireless modem (optional function).
The built-in backup battery will ensure the operation of the device
even with a sudden power failure (optional function).
Cell Phone Signal Booster Feature:
• Automatic and manual adjustment of the signal gain.
• Independent adjustment of Uplink and Downlink gain parameters
with the ability to switch on and off for each subband.
• Intended for installation inside the building.
• Protection against overlapping frequencies of operators.
• High level of integration.
• Lightweight, compact.
• Low heat dissipation during prolonged operation.
• Low energy consumption.
• Universal unit: 100 ~ 240VAC
