Reliable

G3-PLC has an installed user base of over 50 million metering points, making it an extensively field tested technology

G3-PLC is a global standard and is the most common power line technology in use today

Based on the IEEE standard 1901.2 and ITU-T-G.9903, it is compliant to standards across the world

 

  • Power Line Systems network, based on G3-PLC (ITU-T G.9903) architecture, consists of multiple NC1, NC2 or NM7 network nodes and a single network data concentrator (gateway)- DC.
  • The network nodes can exist on any of the three phases of the low voltage (80 – 480VAC) side of the power grid.
  • Each node can be miles out from the nearest node (depending on the number of intermediate power line branches) and maintain network connectivity.
  • The data concentrator (gateway) , DC, connects to one of the  phases of the power grid on the low voltage side.
  • Each DC can support up to 2500 network nodes.
  • Each DC has the capability to communicate with the central SCADA terminal via secure ethernet, WIFI or LTE /CDMA/GSM cellular network.
  • The network automatically installs and is self-healing; there is no field installation necessary other than mounting and wiring of the nodes.
  • An optional LV-LV signal coupler can be used to propagate signals from multiple phases (or multiple transformer secondaries) to the all the phases in the installation.
  • An optional MV-LV signal coupler can be used to extend the connectivity of the gateway across the medium voltage lines for larger industrial complexes or entire neighborhoods.

  • OFDM based physical layer [ BPSK, QPSK, 8PSK] 

  • CENELEC B Band - compliant with world regulatory bodies

  • IEEE, ITU, IEC/CENELEC standards based 

  • Two layers of forward error correction for robust data communications in harsh power line channels

  • Adaptive tone mapping for optimal bandwidth utilization

  • Channel estimation to select the optimal modulation scheme between neighboring nodes.

  • "Robust" mode to improve communication under noisy channel conditions.

  • IEEE 802.15.4-based MAC layer well suited to low data rates.

  • 6LoWPAN adaptation layer to transmit IPv6 packets over powerline channels.

  • Multi layer encryption : Patented Cipher-Stream encryption on top of 256-bit Elliptic Curve Cryptography

  • Coexistence with older S-FSK (IEC 61334), and broadband IEEE P1901 and ITU G.hn standards.

  • Supports IPv6 to allow Internet-based energy management systems and applications.

  • Mesh routing protocol to determine the best path between remote network nodes
