HD-PLC Alliance > IEEE 1901

HD-PLC technology is fully integrated in the IEEE 1901-2010 Standard for Broadband over Power Line Networks, ratified in December 2010.

HD-PLC technology is the only technology fully conformant with IEEE 1901 including Inter-System Protocol (ISP) coexistence.

Sponsored by the IEEE Communications Society, this globally recognized BPL standard is designed for use in a wide range of applications including smart energy, transportation and Local Area Networks (LANs) in both residential homes and enterprise.

IEEE 1901 introduces sophisticated modulation techniques that are similar to what is used in WiFi and Wavelet Orthogonal Frequency Division Multiplexing algorithms. These innovations overcome traditional BPL technical concerns, such as RF noise generated in power lines, regional discrepancies in voltages and other power-transmission characteristics around the world, and the complexities of transmitting data through transformers.

The result is that IEEE 1901-compliant networking products deliver high-performance, interference-free and secure data transmission in excess of 500 Mbps in LAN applications?even when multiple BPL technologies are connected to the same wire?and range of up to 1,500 meters for first-mile/last-mile services.

Two technologies are implemented in the IEEE 1901 Standard. One is HD-PLC technology based on a wavelet modulation the second one is based on FFT modulation. IEEE 1901 specifies a mandatory mechanism that allows coexistence both between those two technologies and between BPL and other technologies. The IEEE 1901 Inter-System Protocol prevents interference when the different BPL implementations are operated within close proximity of one another. The IEEE 1901 ISP also has been extended to International Telecommunication Union's family of home networking standards ITU-G.hn, and is the U.S. National Institute of Standards and Technology's recommended coexistence mechanism for broadband power line communications.

HD-PLC technology is the only technology fully conformant with IEEE 1901 including Inter-System Protocol (ISP) coexistence

Effectively transforming any conventional electrical outlet into a networking node, the products support a range of compelling applications, among them:

  • high-definition video streaming,
  • Internet Protocol gaming,
  • expanded data communications,
  • simplified image and sound distribution,
  • enhanced home security and
  • enterprise services such as home automation, digital signage and triple-play communications.

Now, with the likelihood of IEEE 1901 being adopted as an embedded capability in appliances and networking systems, the standard is set to unlock other innovative smart grid applications that will make consumers eager for more. New entertainment playlists, for example, could be downloaded to electric vehicles while charging overnight, and entertainment could be delivered more simply to the seats of airplanes, trains and other mass-transit vehicles.

Upon this revolutionary capability will be built some of the smart grid's most exciting consumer innovations—a development that comes just in time for manufacturers, utilities and other stakeholders around the globe.
