Outdoor 2W LTE800 EGSM900 ICS repeater 4g 2g 3g gsm booster mobile phone signal amplifier

The ICS Repeater (Interference Cancellation System) is a new kind of single-band RF repeater that can automatically detect and cancel the interference signals caused by oscillation of RF feedback between the Donor and Coverage Antennas in real time by adopting DSP (Digital Signal Processing) technology. It can continuously and stably cancel the interference signals and be adapted to any changes in the surrounding RF environment (including fixed and mobile objects).

Main Features

Traditional outdoor site is often affected by the local installation environment limit so it cannot improve the isolation between the donor antenna and the retransmission antenna. Cause the equipment cannot be erected and normally open, ICS repeater can be very good to solve this kind of problem.
High Gain of Equipment

The traditional wireless outdoor site because conditions by isolation must be greater than the gain of 15dB, cause equipment gain can not be bigger because of impacting by erecting environmental, ICS repeater get rid of the aforementioned influence, Can increase the equipment gain, and achieve the weak signal area normal coverage.
Uplink Squelch Function

The introduction of digital technology and application of software radio programming makes the equipment have the uplink squelch function, greatly reduced the interference to the base station by Repeater.
Compared with the wireless repeater, ICS repeater has the following advantages:

The antenna isolation requirements can be reduced more than 35dB, Receiving antenna and antenna using the same holding pole, thereby reduce the installation difficulty and cost.
In the same antenna isolation conditions, the whole machine gain can be increased more than 35dB, to achieve more coverage scope.
Has uplink noise suppression function, the impact to base station receiver sensitivity is small.
Has the automatic gain and level control function, ensure the output power is constant.
No special requirements on the feedback path between the receiving antenna and transmit antenna, can adapt to various installation site.
