Band 3 1800MHz 40dBm ICS Band Selective High Power Repeater
The EMTS Telecom Services Ltd. 1800MHz High Power Repeaters (IHPR) provides an excellent solution to the problem of poor signal coverage for coverage extension and outdoor or in-building applications. The IHPR has the option to utilize 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 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 GSM & LTE, selected by a digital mechanism.
