Multi-Standard OFDM Narrowband Power Line Communication Chip for Smart Grid Applications

Semitech Semiconductor its SM2400 device, a multi-standard OFDM based PLC transceiver, the SM2400 is designed with ultimate flexibility to operate in a wide range of noise prone smart grid environments, while addressing a multitude of established and evolving standards and proprietary modes.

Regional requirements and differing standards further complicate communications over the already notoriously noisy power grid. The SM2400 combines a cost-effective design that has been optimized for PLC applications with a high level of programmability to address a multitude of communications schemes and evolving standards. Extremely flexible, the SM2400 features a dual core architecture to guarantee superior communication performance while maintaining a very high level of flexibility and programmability for OFDM based and other standards - as well as proprietary and fully customized implementations.

The SM2400 is a future proofed PLC solution supporting all common OFDM based standards including: IEEE 1901.2, G3-PLC and PRIME, with high flexibility to address standard evolution, new standards and special proprietary modes. The SM2400 is the second generation of OFDM based solutions from Semitech. It builds upon its SM2200 field proven performance to add further programmability multi-standard compliance and power efficiency, while allowing for flexible channel adaptation and higher data rates of up to 500Mbs.

Applications for the SM2400 include advanced metering infrastructure and automated meter reading, street lighting control, smart energy home area networking, home automation, building automation, and other deployments requiring communications over an existing power line.
