Claim:
1. A method in an access point (AP) for adaptive beacon transmission, the AP transmitting a beacon signal through a plurality of beacon beams in an area served by the AP, the plurality of beacon beams being grouped into a plurality of beacon beam sets, the method comprising: obtaining a first statistical information, within a first period, based on times when each of the plurality of beacon beams in a first beacon beam set is identified, by any one of at least one communication device within the area, to carry the beacon signal with a best reception quality, wherein each of the plurality of beacon beams is identified to carry the beacon signal with the best reception quality based on a comparison of reception qualities measured at the communication device, and wherein each one of the reception qualities is determined based upon at least one of a strength, Signal to Interference and Noise Ratio (SINR) and the Signal to Noise Ratio (SNR) of the beacon signal when received at the communication device from the AP through a beacon beam from the plurality of beacon beams; and adapting a frequency to transmit the beacon signal over each of the plurality of beacon beams in the first beacon beam set based on the first statistical information, wherein the adapting includes:
