A system for broadcasting and receiving a beacon signal includes a beacon transmitter () and a beacon receiver (). The beacon transmitter includes a beacon signal generator () to generate a beacon signal, and a directional antenna system () to selectively transmit the beacon signal in a corresponding one of M different directions during each one of M beacon slots () during a beacon period () in each of a plurality of superframes (). The beacon receiver includes a beacon signal detector () to receive and detect the beacon signal, and a directional antenna system () having an antenna pattern including a main lobe and being adapted to selectively steer the main lobe in a selected one of N different directions during each of a plurality of receiver frames each having a time period substantially equal to a time period of one of the superframes.
