HOME-PNA
HomePNA (also known as Home PNA, HPNA, Home Phoneline Networking Alliance, Home Phoneline Networking and Homepna) is an incorporated non-profit association of more than 150 companies, including the founding companies Epigram, Inc., 3Com, AMD, AT&T, Compaq,HP, IBM, Intel, Lucent, Rockwell and Tut Systems. The Home Phoneline Networking Alliance seeks to establish standards among telecom, computer and network products such that they are compatible for HomePNA. Home Phoneline Networking Alliance does not enforce standards; it provides advice to the International Telecommunication Union (ITU) which is a standards body.
POWER LINE COMMUNICATION
Power line communication (PLC), also called Mains Communication, Power Line Telecoms (PLT), Powerband or Power Line Networking (PLN), is a term describing several different systems for using power distribution wires for simultaneous distribution of data. The carrier can communicate voice and data by superimposing an analog signal over the standard 50 or 60 Hz alternating current (AC). It includes Broadband over Power Lines (BPL) with data rates sometimes above 1 Mbit/s and Narrowband over Power Lines with much lower data rates. Traditionally electrical utilities used low-speed power-line carrier circuits for control of substations, voice communication, and protection of high-voltage transmission lines. High-speed data transmission has been developed using the lower voltage transmission lines used for power distribution. A short-range form of power-line carrier is used for home automation and intercoms.
