In one example, a repeater system includes a master unit on a movable object configured to couple to antennas for receiving a downlink RF signal from at least one base station external to the movable object and for transmitting an uplink RF signal towards the at least one base station; and a plurality of remote units each configured to couple to the master unit, each positioned on the movable object and associated with different coverage areas, the remote units each configured to couple to a respective antenna system for transmitting the downlink RF signal into respective coverage areas and for receiving the uplink RF signal from the coverage areas, a control unit, wherein, for at least a subgroup of the remote units, a gain for each remote unit is dynamically adjusted in a time-offset fashion by the control unit to trigger handovers between overlapping base-station cells in a time-offset manner.
