2W LTE800 ICS Repeater Mobile Phone 4g 2g 3g Signal Amplifier Booster Repeater
Greetwin’s ICS Repeater is used for GSM, DCS, or WCDMA signal coverage extension especiallys for outdoor applications. The ICS Repeater is able to cancel the real-time multi-path feedback signals by using the digital signal processor technology and avoid interference due to insufficient isolation. With 30 dB of isolation cancellation capability, the service antenna and the donor antenna can be installed on the same medium size tower with a short vertical distance. Therefore, the application of RF outdoor repeater would become much easier and cost-effective.
These units can be applied to outdoor environments where high
towers are not available. For example, highway areas, tourist
spots.

Good Isolation
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 fiber optic repeater, ICS repeater has the following advantages:

Working Principle:
Through unique digital processing technology, ICS repeater
effectively capture and tracking the transmission characteristics
of external leakage path, The transmission characteristics can be
equivalent to a FIR filter, it is called mirror filter. send the
signal which will be sent to the mirror filter, under the ideal
condition, External leakage signal in the signal which is export
and reception by mirror filter is exactly the same, so that you can
subtracts the mirror filter output in the input signal, to suppress
the interference. Because of the external leakage environment is
unknown and changing, ICS repeater first needs catch the
transmission characteristics of leakage path in feedback inhibition
calibration status, and keep trace the external environment changes
in normal operation.
