Abstract
The operational range of a wireless controller is extended by use of RF communications instead of or in addition to other signaling radiation such as infrared. Advantageously, power line communications technology is used to extract an RF signal from the power line of the device. The power line also is used as an antenna for a transceiver so as to minimize the size of the transceiver and to provide an improved antenna.
