Claim Text:
1. An electronic device, comprising: first and second cellular telephone antennas; radio-frequency transceiver circuitry that transmits and receives radio-frequency signals through the cellular telephone antennas, wherein the radio-frequency transceiver circuitry has a first receiver that is associated with a first transceiver port and a second receiver that is associated with a second transceiver port; and switching circuitry interposed between the radio-frequency transceiver circuitry and the first and second cellular telephone antennas; control circuitry configured to change the switching circuitry from a first state, in which the first cellular telephone antenna is coupled to the first receiver and the second cellular telephone antenna is coupled to the second receiver, to a second state, in which the first cellular telephone antenna is coupled to the second receiver and the second cellular telephone antenna is coupled to the first receiver, in response to determining that the performance of the second cellular telephone antenna is superior to the performance of the first cellular telephone antenna; wherein the determining that the performance of the second cellular telephone antenna is superior to the performance of the first cellular telephone antenna is based at least partly on, during a transmission by the radio-frequency transceiver on at least one of the antennas, detecting that power being transmitted by the radio-frequency transceiver through the first antenna during the transmission exceeds a threshold.
