A wireless local area network (WLAN) device comprising a processor, a transceiver coupled to the processor, a switching mechanism coupled to the transceiver, a beamforming antenna assembly coupled to the switching mechanism, and a multiple input, multiple output (MIMO) antenna assembly coupled to the switching mechanism. Included is an apparatus comprising a processor and a memory coupled to the processor, wherein the memory comprises instructions that cause the processor to calibrate a WLAN device, select an optimal antenna configuration, track the WLAN device performance, and wait for a triggering event. Also included is an adaptive antenna method comprising calibrating a WLAN device, selecting an optimal antenna configuration, tracking the WLAN device performance, and waiting for a triggering event.
