Multi-Band Active DAS is designed to solve the problems of weak mobile signal in the place that is far away from the Base Transceiver Station(BTS) and has fiber optic cable network underground. It is often used with optical fiber repeater.
DAS means distributed antenna system, this system consists of two parts: Master Unit and Remote Unit. Below is the application diagram:
