1. A wireless communication device, comprising:
a transmitter configured to communicate according to a first communication protocol;
a receiver configured to communicate according to a second communication protocol that is different from the first communication protocol;
a first antenna coupled to the transmitter;
a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance;
