A method for transmitting beacon transmissions in a wireless local area network (WLAN) communications system () operating on one or more channels includes transmitting a first beacon (C) using a directional antenna in a first direction (D) on a first channel. A second beacon (C) is then transmitted using a directional antenna in a second direction (D) on the first channel. This process is then repeated such that the first beacon and second beacon after a predetermined beacon interval. The first beacon begins its transmission at a target beacon transmission time (TBTT) and the second beacon begins its transmission in a sequential period defined by an antenna switching time after the transmission of the first beacon.
