Patent ID: 7801556

Claim:
A wireless communication device comprising: a transmit antenna with a first tunable element to change a first transmit frequency band associated with a first communication mode to a second transmit frequency band associated with the first communication mode or a second communication mode, wherein the first tunable element is controlled by a first control unit for transmissions by the transmit antenna and not receptions by the transmit antenna, wherein the transmit antenna is tuned to the second transmit frequency band based on the device determining one or more of a signal-to-noise ratio (SNR), a frame error rate (FER), and a bit error rate (BER) associated with the second transmit frequency band; and a receive antenna with a second tunable element to change the first receive frequency band associated with the first communication mode to a second receive frequency band associated with the first communication mode or the second communication mode, wherein the second tunable element is controlled by a second control unit for receptions by the receive antenna and not transmissions by the receive antenna, wherein the receive antenna is tuned to the second receive frequency band based on the device determining one or more of a signal-to-noise ratio (SNR), a frame error rate (FER), and a bit error rate (BER) associated with the second receive frequency band.
