Patent ID: 8804624

Claim:
A wireless communication device comprising: a first transceiver configured to transmit a first signal, wherein the first transceiver operates according to a first wireless communication standard; a second transceiver configured to (i) select a first channel of a plurality of channels, and (ii) transmit a second signal on the first channel, wherein the second transceiver operates according to a second wireless communication standard, and wherein the first channel is associated with a frequency; a coexistence module configured to, based on the frequency of the first channel, i) alter a transmission characteristic of the first signal to be transmitted by the first transceiver, and ii) alter a transmission characteristic of the second signal to be transmitted by the second transceiver, wherein the transmission characteristic of the first signal and the transmission characteristic of the second signal, as altered by the coexistence module, prevents interference (i) between the first signal and a signal received by the second transceiver, and (ii) between the second signal and a signal received by the first transceiver; a plurality of switches comprising a first switch comprising a first node connected to an antenna, a second node, and a third node, a second switch comprising a first node connected to the second node of the first switch, a second node connected to the third node of the first switch, and a third node connected to the first transceiver, and a third switch comprising a first node connected to the third node of the second switch, a second node connected to the third node of the first switch, and a third node connected to the second transceiver; and a switch controller configured to generate a plurality of control signals to change states of the plurality of switches to connect the first transceiver or the second transceiver to the antenna.
