Dual Band Cell Phone Signal Boosters 20dBm 900MHz 2100MHZ Low Heat Dissipation
Cell Phone Signal Booster Description:
Greetwin 900/2100MHz Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low-power signal from BTS via radio frequency (RF) transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted tothe BTS via the opposite direction.
The digital 900/2100MHz dual band selective repeater is an alternative to traditional signal amplifiers in the standards GSM900/WCDMA2100. 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; 2100MHz, each 0.2 ~ 15MHz, configurable and adjustable within the frequency range of 900/2100MHz
Band Selective 900/2100MHz repeater is designed to amplify the mobile 900/2100MHz 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
