Power Line Communications

The smart grid implements two-way communication channels over existing power distribution networks. Modern networks might be comprised of a variety of new alternative energy sources. These sources include solar and wind power as well as new types of electric appliances, such as smart appliances and electric vehicles. In many parts of the world, narrowband power line communications (PLC) technology has proven to be a robust and cost-optimized solution in large deployments of smart meters.

Atmel® offers PLC solutions designed specifically for narrowband communications using the low-voltage electric grid. Drawing on our deep expertise in PLC modem technology and extensive collaboration with utilities and metering OEMs, we’ve created solutions offering an unprecedented level of integration and performance. Our solutions support various modulation schemes including the PRIME (PoweRline Intelligent Metering Evolution) specification, an open and multi-provider industry standard promoted by an industry alliance of more than 30 leading utilities, meter manufacturers, and silicon providers. Thanks to the communications software provided by our solution, the management of PLC networks turns into a transparent process. Users can focus on top-level applications and access the Atmel® PLC software stack via user-friendly application programming interfaces (APIs).
