Description
Digital ICS Repeater (Interference Cancellation System) is a new kind of RF Repeater that can automatically detect and cancel the interference signal caused by oscillation of RF feedback between the Donor and Services Antennas in real time by adopting DSP (Digital Signal Processing) technology, which restores full operational capability against multi-path fading cellular signals and feedback signals by oneself and all types of waveforms from both friendly and intentional sources of interference.
Same to RF Repeater, the Digital ICS Repeater is working as a relay between the BTS and mobiles. It picks up the cellular signal from the BTS via the Donor Antenna, linearly amplifies the cellular signal and then retransmits it via the Services Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
As per operator's requirement for working frequency, two types of ICS repeater are available:
- Band Selective ICS Repeater: to amplify all signals in the whole band (Various bandwidth is available upon request)
- Channel Selective ICS Repeater: to amplify only the signals transmitted by the customized 1 or 2 or 4 or 6 or 8 or 12 channel (A narrow band with customized central frequency)
Features
- Aluminum-alloy casing with IP65 protection and compact design, cool system without fan
- Real-time cancellation of interference signal (incl. multi-path fading, feedback signal)
- ICS function to prevent self-oscillation, enhance gain and coverage range and reduce isolation requirement
- In-built AGC & ALC function be able to ensure easy installation without setting
- Unique max AGC60dB firmware to ensure stable operating on moving platforms such as ship or trains
- Compact size and light weight, easy to install on wall or pole
- High working gain as Min. 90dB
- Output power +30dBm - +43dBm for large coverage application
- Filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
- Built-in wireless modem (Option) for remote monitoring by SMS
- Details repeater parameters and status can be monitored by software
- High gain linear power amplifier technique with reliable performance
Application
- Outdoor/Rural: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages, ……
- Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots, ……
The ICS Repeater is mainly applicable to such cases:
- The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than -70dBm;
- And the isolation requirement is hard to meet by using a RF Repeater.
