AMM solution based on OFDM technology to be developed by Sagem Communications and Maxim


Sunnyvale, CA, U.S.A. — (METERING.COM) — September 25, 2008 – An agreement has been entered into between Maxim Integrated Products and Sagem Communications to develop an open powerline communication (PLC) specification targeting automatic meter management (AMM) infrastructure.

Drawing on their experience in advanced metering, communications, and IC design, the companies will establish a comprehensive set of international specifications to promote interoperability among different PLC manufacturers. As an open standard, the PLC specification will facilitate the implementation of AMM infrastructure, increase cost efficiency by promoting interoperability, and accelerate the widespread adoption of orthogonal frequency-division multiplexing (OFDM)-based PLC technology.

This breakthrough technology enables more robust communication and higher data rates over longer distances than conventional narrowband technologies.

Earlier this year, Maxim introduced the world’s first OFDM-based PLC modem operating over the 10 to 490 kHz frequency range. The modem employs advanced, broadband networking techniques to achieve reliable and secure data communications under adverse channel conditions, and over longer distances than traditional PLC modems. The modem’s software configurability ensures worldwide compliance, and will serve as the basis for the new PLC specification.

Maxim is a designer, manufacturer, and seller of high performance semiconductor products.

Sagem Communications is an electronic metering specialist, with almost 10 million electronic meters already in the field. The company has extensive experience developing and deploying interoperable AMM PLC systems in which meters from different suppliers can communicate without any previous software adaptation.
