20dBm Dual band 900MHz 1800MHZ Band Selective Digital Repeater
Digital Repeater Description:
In mobile communication repeaters would be an optimal solution to cover areas that can't be covered by base stations. Greetwin band selective repeater is an ideal solution for operators in more than one system and more than one sub bands. Band selective repeater is mainly used in areas with no or weak signal such as office restaurants, apartments, shopping malls, parking lots etc.
The digital 900/1800MHz dual band selective repeater is an alternative to traditional signal amplifiers in the standards GSM900/DCS1800. 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, each 0.2 ~ 20MHz, configurable and adjustable within the frequency range of 900/1800MHz
Band Selective 900/1800MHz repeater is designed to amplify the mobile 900/1800MHz 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).
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
