Download Datasheet (PDF)

The EMTS Telecom Services 450 MHz Band Selective ICS Power Repeaters (IPR), supporting band-31, provide an excellent solution to the problem of poor signal coverage for coverage extension and in building & outdoor applications. The IPR amplifies the signals from mobile phones and base stations and can be used in dead areas where coverage is poor. The EMTS IPR also improves cellular network capability by improving data coverage in areas with limited signal strengths. The IPR is connected to an outdoor donor antenna using a coaxial cable. The donor antenna transmits signals from mobile phones and receives signals from the BTS service antennas placed in dead zones or towers for outdoor applications. Signals from mobile phones used in the dead zones are then received by the service antenna and transmitted to the IPR donor antenna, which transmits the signals to the base station. The Repeater Advanced Adaptive Echo Interference Cancellation technology always provides optimized signal coverage. The special design allows fast network deployment, real-time isolation detection, and ICS operation, ICS (Interference Cancellation System) eliminating oscillation between Service and Donor Antennas using Digital Signal Processing.
