Broadband over power lines (BPL) is a method of power line communication (PLC) that allows relatively high-speed digital data transmission over the public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range and different technologies from other forms of power-line communications to provide high-rate communication over longer distances. BPL uses frequencies which are part of the radio spectrum allocated to over-the-air communication services; therefore the prevention of interference to, and from, these services is a very important factor in designing BPL systems.
Broadband data services over vehicle power lines
InactiveUS20050143868A1Improving S/N for transmission/receivingDigital data processing detailsElectric forceMobile vehicle
A method of providing broadband data services over power lines for moving vehicles is provided herein. Using broadband over power line (BPL) networking, a data signal is connected to a vehicle that is connected to a transport power line. The signal is communicated from the transport power line to the vehicle. The signal is then demodulated for use aboard the vehicle. The data signal connection allows for access to wide area networks such as the Internet. Access points can wirelessly broadcast wide area network signals from stationary locations to define meshed wireless networks in metropolitan areas.

Broadband coupler technique for electrical connection to power lines
ActiveUS7145440B2Creating unreasonable safety riskEliminate needCoupling device connectionsElectric signal transmission systemsElectric power transmissionTransceiver
Disclosed is a power line broadband communication system having broadband coupler devices capable of direct electrical connection to an energized power line. The coupler includes a conductive portion movable by an adjustable member from a non-conducting retracted position spaced apart from the power transmission line to a forward conducting position in electrical contact with the power line. An insulated arm supports the coupler on the power line. A base on the coupler is engageable with a remotely activated tool in order to accomplish the electrical connection in a safe and secure manner. Broadband data signals are sent to and from customer premises along the shared energized power lines. New coupler connections to the energized power lines allow the additional broadband customers and / or repeaters to join the communication system. Also couplers may provide connections to control electronics, routers, wireless transceivers, and may allow the broadband signals to bypass transformers on the power lines. The invention helps to minimize risk by allowing an installer to be remotely spaced from the energized power line while making the electrical coupling contact with the energized power line.
