Product Description

1-40W 105dB GSM 900MHz Mobile Signal ICS Repeater

Overview:

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).

Features
1.  Good Isolatioan
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.
2.  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.
3.  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.
4.  Compared with the wireless repeater, ICS repeater has the following advantages:
a)   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.
b)   In the same antenna isolation conditions, the whole machine gain can be increased more than 35dB, to achieve more coverage scope.
c)    Has uplink noise suppression function, the impact to base station receiver sensitivity is small.
d)   Has the automatic gain and level control function, ensure the output power is constant.
e)   No special requirements on the feedback path between the receiving antenna and transmit antenna, can adapt to various installation site.
5.  Compared with fiber optic repeater, ICS repeater has the following advantages:
a)   Does not need to rely on the fiber resources, can reduce the cost of installation.
b)   There is no Local unit, reducing failure rate.
6.  Compared with frequency shift repeater, ICS repeater has the following advantages:
a)   Work in the same frequency band, saving frequency resources.
b)   Don't need OCXO, avoid because of constant temperature crystal aging induced frequency drift.
c)    There is no Local unit, reducing failure rate.
