1. A method for non-regenerative repeating of a signal transmitted from a first station to a second station according to a Time Division Duplex (TDD) protocol, the first station communicating to the second station on a downlink and the second station communicating to the first station on an uplink, the method comprising:

  • detecting the presence of the signal in an interval associated with one or more of the uplink and the downlink;

    re-transmitting the signal from the second station to the first station using a first antenna directed toward the first station if the signal is detected on the uplink; and

    re-transmitting the signal from the first station to the second station using one of a second antenna directed toward the second station, and an omni-directional antenna, if the signal is detected on the downlink,wherein a form factor associated with one or more of the first antenna, the second antenna, and the omni-directional antenna facilitates the detecting and the re-transmitting.
