Abstract
In certain embodiments, an apparatus includes circuitry coupled to a switch between a first and second antenna of a device. The circuitry generates a first control signal for the switch to couple a transceiver of the device to the first antenna for transmission of a first data frame. The circuitry determines whether the transceiver has received, within a pre-determined time interval after transmission of the first data frame, a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device. The circuitry generates, if the transceiver has not received the second data frame within the pre-determined time interval, a second control signal for the switch to couple the transceiver to the second antenna for re-transmission of the first data frame. An output line of the apparatus couples the circuitry to the switch and communicates the first or second control signal to the switch.
