1. A time division duplex repeater system, comprising:

  • two antennas serving first and second coverage areas, the second coverage area being an extension of the first coverage area;

    a switched directional amplifier coupled between the two antennas, wherein said switched directional amplifier is controlled to only provide amplification of a signal associated with one of said first and second coverage areas at any particular point in time; and

    control circuitry coupled to the switched directional amplifier and to the two antennas, the control circuitry being adapted to receive transmissions from the first and second coverage areas and apply control signals to the switched directional amplifier to control a signal path direction for said amplification by said switched directional amplifier.
