Abstract: Example systems and methods of a wireless device use a signal attribute detector to determine a signal attribute value associated with a first frame received via a first antenna. Media access control (MAC) logic can detect that the first frame indicates an acknowledgement (ACK) of a second frame transmitted by the wireless device. Responsive to the detection of the ACK by the MAC logic, an antenna evaluator uses the signal attribute value to select one of the first antenna and the second antenna to transmit or receive a third frame.
