Abstract
The RF signal generated by a ZigBee radio on the outside of a building structure is conveyed to the interior of the building by guiding it as a surface wave along an electric cable bundle that passes through the building's wall to supply domestic electric power to the interior of the structure. The RF signal is launched by a unique coupler comprising a pair of insulated foil conductors.
