About PLC Solutions
Regulatory and technological incentives drive Distribution System Operators (DSO’s) towards smart metering solutions, in which data is transferred between electricity meters and the DSO’s central database through a communication network.
The use of Power Line Communication (PLC) is a very favourable solution, since data is sent over the DSO’s proprietary electricity grid. However, the few solutions that are available on the market, including OFDM based solutions, suffer from high frequency noise inserted in the network by modern technologies and low input impedances present in modern electrical equipment.
Therefore, Eandis decided in 2008 to develop a filter which is specifically designed to remove noise from the distribution network and increase the input impedance. In 2010, a proof-of-concept, involving smart metering of 4000 households, showed that the filter is able to successfully remove the noise from the network, enabling low-cost Q-PSK based PLC communications to do the job.
Today, Eandis is executing a roll-out of the technology for 40.000 households in which the multi-gateway filtered PLC Q-PSK technology will be fully compliant with the operational Meter Data Management systems.
Eandis is proud to offer the technology to solution providers and technology providers worldwide.
