Band 28 700MHz 43dBm ICS High Power Repeater
The EMTS Telecom Ltd. Band 28 ICS High Power Repeaters (IHPR) provide an excellent solution to the problem of poor signal coverage for coverage extension and outdoor or in-building applications. The IHPR utilized Digital ICS technology (Interference Cancellation System), The 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. It restores full operational capability against multi-path fading cellular signals and feedback signals by oneself and all types of waveforms from friendly and intentional interference sources. Easy installation, lightweight design, and friendly GUI make the EMTS IHPR a cost-effective and practical solution for extending signal coverage.The EMTS, High Power Repeater series, supports all frequencies, including WCDMA& LTE& 5G,selected by a digital mechanism.
