The AMM/AMI market sets new requirements for the communication parameters within the automated metering systems. Companies have to manage larger volumes of data, even in a shorter period of time.

ADD GRUP has developed an OFDM modem for faster transmission of data on PLC LV and MV networks. OFDM represents a new modulation scheme, allowing higher communication speed and higher data penetration, compared to FSK modulation.
The modem allows data rates up to 76,8 kbps for one mains phase (up to 230 kbps for 3-phase communications), and the shift from S-FSK to OFDM can easily be made.

ADDAX Technology is now completely based on OFDM, bringing more advantages for the utilities using ADDAX AMM/AMI system in terms of speed and reliability!
