The world first ICS Digital Relay commercialized by RF Window has Interference Cancellation System eliminating Oscillation between Service and Donor Antennas by using DSP(Digital Signal Processing).    The ICS system is able to effectively eliminate all multi-path signals including, direct feedback from the coverage antenna, indirect feedback from predictable obstacles (e.g. buildings, bridges, mountains) and can even cancel indirect feedback from unpredictable obstacles (e.g. pedestrians, vehicles, trees) despite changes in feedback signal timing and amplitude on 2G, 3G, and LTE networks.    The Digital DAS is in-building multi-operator distributed antenna system being able to provide CDMA, WCDMA, LTE, Ethernet with Wi-Fi service simultaneously for the sake of filling up shadow area. The Digital DAS transmits signal from MU(Master Unit) connected multi-operator BTS, Node B to HU(Hub Unit) by optic cable and distributes by optic cable from HU(Hub Unit) to RU(Remote Unit).   It provides consistent coverage to the end users by minimizing transmission loss, which is one of the weakness of existing passive DAS system and can set up effective distributed network.
