About G3-PLC
G3-PLC is a global, open powerline communication protocol specifically
designed for smart grid communications and recently standardized by the ITU.
It enables smart meter management, control and monitoring of the electrical
distribution network, energy management, electric vehicle charging, lighting
control and other smart grid applications. The key objectives of the G3-PLC
Alliance are to certify the compliance of new G3-PLC products to the
specifications, to insure their interoperability, and to help manufacturers
and end users to develop and use the G3-PLC technology efficiently.

The G3-PLC specification is designed to operate in 10-490 kHz frequency bands
and is compliant with CENELEC, FCC and ARIB regulatory bodies. It was designed
to meet the following requirements:

  oRobustness: communications profile suited to operate in severe noisy
    environments such as low-voltage lines, long-range communications in
    medium-voltage lines.
  oPerformance: bi-directional digital communications with data rates up to
    300 Kbps
  oSimplicity: simple to implement, install (Plug-and-Play), operate and
    maintain
  oSecurity: it offers a safe environment using an AES-128 cryptography
    engine
  oScalability: Supports IPv6 for new internet-based energy management
    systems and applications for utilities and DSO's to better manage their
    assets on the grid.
  oCost: Long range communication and reliable data transmission reduces the
    number of repeaters. Plug-and-Play architecture and intelligent mesh
    networking reduces installation time.
