Seamless evolution of PLAN+ base ARM systems using multicarrier communication technology

Can today´s widely deployed S-FSK/PLAN+ based AMR systems evolve towards a faster and more robust multicarrier technology? This paper demonstrates how multicarrier technology addressses the challenge of achieving the higher levels of performance required by today´s Smart Grid. A communication speed of 10kBaud and an “ultra robust mode” feature are proposed using an `evolution, no revolution´ strategy. Capitalizing on the field proven IEC61334-5-2 standard, this solution offers true backward compatibility with smart meters already installed. It eliminates the risks associated with deployment of alternative modulation techniques while reducing both Capex¹ and Opex² for the ultilities.
