Specifications

 AS the traditional Wireless RF Repeater, the Wireless Digital ICS Repeater can also achieve the bidirectional amplification of the base station uplink and downlink signal. Applied to expand and extend the base station coverage, fill signal area where mobile signal is blind and weak. But it's a new type repeater which adopts Digital Processing Technology to detect and counteract interference signal from wireless received signal. Its specialty is to dispel interference, improve system gain and greatly reduce device's requirement for isolation at the same time. Its capability and function satisfy the Traditional Wireless Repeater protection. Thinks to the ICS technology, the device can be set without the limits of antenna isolation. The transceiver use a holding pole, antenna feed is easy to install, small occupation of land, and convenience for property coordination. By adopting digital processing, the ICS Repeater can debase the introduced noise of device effectively; reduce CAPEX by replacing part of the traditional Frequency Shifting Repeater application. The ICS Repeater also has the ability to Carrier Tracking, makes the device operating channel automatically regulate to the source frequency channel of donor antenna, debase the device maintenance cost.

Product Category:
According to operators' requirement for working frequency, either type of ICS Repeaters can be chose:
ICS Band Selective Repeater: amplify all signals in whole band (the band can be customized).
ICS Channel Selective Repeater: only amplify the signal in one (two or four or six or eight or twelve) appointed channel (namely, the narrow band which center frequency can be appointed).
