Abstract
A wireless device includes a radio, a first directional antenna, a second directional antenna, an omnidirectional antenna, and a switch selectively coupled between the radio and the first directional antenna, the second directional antenna, and the omnidirectional antenna. A processor is coupled to the switch and to, for a frame: determine, based on an arbitration table, a destination medium access control address of a client wireless device and identifiers of antennas for transmitting the frame and receiving acknowledgement data; cause the switch to couple the radio to the first directional antenna; transmit the frame to the client wireless device via the first directional antenna, wherein the first client wireless device is located along a first direction with respect to the wireless device; cause the switch to couple the radio to the omnidirectional antenna; and receive an acknowledgment, corresponding to the frame, from the client wireless device via the omnidirectional antenna.
