The plug is fixed to the electrical fixture, while the socket is fixed to the surface (e.g., wall, ceiling, or floor) or electrical junction box on which the fixture will be mounted. The construction, function, and operation of the plug and mating socket have been described in detail, for example, in patents and applications incorporated herein by reference.

[0048] The "smart quick-connect device" disclosed herein is generally defined as a connector that has additional functions beyond the conventional capability of providing connectivity. The smart quick-connect device may include a sensing unit for sensing wireless communication status. Alternatively or additionally, the smart quick-connect device may include a sensing unit for wirelessly receiving signals.
