20dBm Four Band 900/1800/2100/2600MHz Band Selective Digital Repeater
Digital Repeater Description:
The Greetwin Four Band 900/1800/2100/2600MHz Digital Band Selective Repeater is a newly designed mobile signal repeater with intelligent functions, it’s main purpose is the help the mobile operators to enhance the indoor cellular coverage. The repeater is using the industrial band selective solution with IF SAW filters, which could only boost the signal of the specific frequency of a operator, which reject the competitors’.
The Four Band 900/1800/2100/2600MHz 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; 2600MHz, 4 sub-bands, each 0.2 ~ 15MHz, configurable and adjustable within the frequency range of 900/1800/2100/2600MHz.
Band Selective 900/1800/2100/2600MHz repeater is designed to amplify the mobile 900/1800/2100/2600MHz 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
