Outdoor 90dB Gain 2W EGSM900 Mobile Phone ICS Repeater

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

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.

Compared with fiber optic repeater, ICS repeater has the following advantages:

• Does not need to rely on the fiber resources, can reduce the cost of installation.
• There is no Local unit, reducing failure rate.

• Compared with frequency shift repeater, ICS repeater has the following advantages:

• Work in the same frequency band, saving frequency resources.
• Don't need OCXO, avoid because of constant temperature crystal aging induced frequency drift.
• There is no Local unit, reducing failure rate.

• Through unique digital processing technology, 900M 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, 900M 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.
