However, unlike most wireless protocols, UPB does not require an automation controller or hub to operate. Since UPB is a peer to peer protocol, individual switches, scene controllers and various types of plug-in modules can be individually programmed to do multiple tasks without the need to purchase a hub or controller.
Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used. This avoids any need to access wires and makes remodelling fast and simple.
Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...

Power-line carrier communication (PLCC) is mainly used for telecommunication, tele-protection and tele-monitoring between electrical substations through power lines at high voltages, such as 110 kV, 220 kV, 400 kV. [4] The modulation generally used in these system is amplitude modulation. The carrier frequency range is used for audio signals ...
