A wireless communication device may be configured to transmit and receive
data through a physical device, such as a cable. Relatively higher
transmit radio frequency (RF) signals from the wireless communication
device may be shifted to a relatively lower frequency, thereby enabling
the relatively lower frequency signals to be carried by the physical
device. Similarly, relatively lower frequency signals from the physical
device may be shifted to relatively higher frequencies, thereby enabling
the wireless communication device to receive the signals from the
physical device. In one embodiment, the frequency of the RF signals may
be between 2.3 and 2.7 GHz and the frequency of the relatively lower
frequency shifted signals may be between 900 and 1100 MHz.
