Power Line Communication (PLC) is a well-established communications technology that was initially used for telemetry purposes. The first large-scale PLC deployments took place in the 1990s. Today, PLC technology has reached maturity with many vendors offering fully operational communication solutions for a wide range of industry applications.

In the late 1990s, energy utilities set out to use PLC technology in the smart metering rollouts, which has turned it into the dominant smart metering communications technology in Europe. PLC proved to deliver reliable performance at reasonable procurement, installation and operation cost points.

In recent years, new open OFDM-based PLC technologies have been developed and are currently being field-tested and deployed. This new generation of PLC technology will provide higher communication bandwidth for future advanced smart grid applications.

Landis+Gyr is a key PLC technology market player and is actively involved in the development of this future technology.
