An access point for a wireless local area network (LAN). In one aspect, the access point includes (i) a media access control (MAC) device, and (ii) a radio frequency (RF) transceiver in communication with the MAC device. The access point uses a random order or a rotating order to access a client station in the wireless LAN, and the client station transmits data to the RF transceiver after at least one of (i) the RF transceiver finishes transmitting directed data to the client station, or (ii) the RF transceiver transmits a null data frame to the client station.
