For many years the electric utility companies have employed power lines to transmit signals in the tens of kHz range for the control of switches and relays on electric power transmission systems. The electric utility companies and internet providers have become interested in employing existing power lines for providing residential and commercial internet access, using frequencies from 1.6 to 30 MHz to attain data rates of 1 or more Mbits/s. Initially intended to provide high-speed internet service to consumers in rural areas, Broadband Over Power Lines (BPL) is of great interest to service providers as power lines reach virtually every home and community in the country. A major concern with BPL is that the data signals impressed upon power transmission lines can emit disruptive electromagnetic interference (EMI) to communications and high frequency (HF) radar receivers residing in the 2-30 MHz band. The NRL Radar Division and the Space and Naval Warfare Systems Center (SPAWAR) Charleston were tasked by the Naval Sea Systems Command to determine what changes in the ambient background noise levels might result from a BPL installation.

Congress has expressed significant interest in increasing the availability of broadband services throughout the nation, both in expanding the geographic availability of such services, as well as expanding the service choices available to consumers. Broadband over Powerlines (BPL) has the potential to play a significant role in increasing the competitive landscape of the communications industry but also has the potential to extend the reach of broadband to a greater number of Americans. BPL, like any technology, has its advantages and disadvantages. Proponents state that (1) BPL is less expensive to deploy than the cable and telephone companies' broadband offerings, (2) it does not require upgrades to the actual electric grid, and (3) it is not limited by certain technical constraints of its competitors. However, critics have expressed ongoing concern that BPL could interfere with licensed radio spectrum such as amateur radio, government, and emergency response frequencies.

Power line communication or power line carrier (PLC), also known as Power line Digital Subscriber Line (PDSL), mains communication, power line telecom (PLT), power line networking (PLN), or Broadband over Power Lines (BPL) are systems for carrying data on a conductor also used for electric power transmission. Electrical power is transmitted over high voltage transmission lines, distributed over medium voltage, and used inside buildings at lower voltages. Powerline communications can be applied at each stage. Most PLC technologies limit themselves to one set of wires (for example, premises wiring), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically the transformer prevents propagating the signal, which requires multiple PLC technologies to be used to form very large networks.
