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.
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).
1.Compare to traditional device, greatly improve the ability of resist self-oscillation, greatly debase the isolation requirement of device in using process.
2.Excel traditional device in noise signal filtering
3.ALC Automatic Control and reflex protection circuit, prevent accidental burnout
4.Adopting advanced LDMOS power amplifier with highly linearity and low intermodulation , excellent linearity and intermodulation indexes of whole machine
5.Simplified engineering installation and transceiver can be installed on a holding pole
6.Perfect Local and remote network monitoring, has initiative alarm function, and parameters can be inquired and set.
7.Supply charging power and backup battery to ensure fault information timely report in time of machine outage, convenient for timely maintain
8.Crate accord with IP65 protection and high heat-dissipation design, able to work outdoor all-weather
9.Overall product series and perfect power grade to satisfy different requirements of network coverage.
