20dBm Tri Band Mobile Phone Signal Enhancer , Mobile Signal Amplifier 900/1800/2100MHz

20dBm Tri Band 900/1800/2100MHz Band Selective Digital Repeater

Digital Repeater Description:

The Band Selective Booster Series provides band selective functions to satisfy the demanding customers (Various bandwidths are also available). The band selective function, together with the strong out-of-band gain, totally avoids improving the competitors’ signal coverage. And also is with Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network.

The Tri Band 900/1800/2100MHz digital band selective repeater is an alternative to traditional signal amplifiers. 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; 1800MHz, 3 sub-bands, each 0.2 ~ 20MHz; 2100MHz, 4 sub-bands, each 0.2 ~ 15MHz, configurable and adjustable within the frequency range of 900/1800/2100MHz.

Band Selective 900/1800/2100MHz repeater is designed to amplify the mobile 900/1800/2100MHz signals. 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).

Digital Repeater 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
