  11. 11. 11 Smart Meter Solutions Confidential Proprietary What is PLC?? Basics “Power-line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers” Power Line Communication (PLC) is a communication technology that sends data over existing power cables
  12. 12. 12 Smart Meter Solutions Confidential Proprietary How does PLC work? • PLC systems operate by adding a modulated carrier signal to the wiring system (AC or DC) • Schemes for Modulating the Carrier Signal: – (S)FSK : (Spread) Frequency Shift Keying – BPSK : Binary Phase Shift Keying (BPSK) – OFMD : Orthogonal Frequency Division Multiplexing Modulated Carrier Signal Power Line
  13. 13. 13 Smart Meter Solutions Confidential Proprietary PLC Categories and Features • Broadband PLC: – Appropriate for high-speed broadband network connections such as to the Internet – Operates at higher frequencies (1.8–250 MHz) – High data rates (up to 100s of Mbps) and is used in shorter-range applications • Narrowband PLC: – Useful for applications requiring narrowband control or low- bandwidth data collection where low cost and high reliability are essential – Operates at lower frequencies (3–500 kHz) – Lower data rates (up to 100s of kbps), and has longer range (up to several kilometers), which can be extended using repeaters
