Abstract

A repeater system includes a first master unit and a second master unit located on the movable object, such as a train. The master units are each connected to an antenna for receiving a downlink RF signal from at least one base station outside of the movable object and for transmitting an uplink RF signal towards the base station. Remote units are associated with different coverage areas within the movable object and are connected to the master units unit via a transport medium. The remote units are each connected to an antenna system for transmitting the downlink RF signal into the associated coverage area of the movable object and for receiving the uplink RF signal from the coverage area. A control unit can control first gain for the connection with the first master unit and a second gain for the connection with the second master unit.
