POWER LINE COMMUNICATION

The lighting control and monitoring solutions developed by Nyx Hemera Technologies use the latest advanced power line communication technologies available on the market.

It uses methods that combine time and diversity techniques to achieve ultra-robust power line communication:

  • The modulation technique is a blend Orthogonal Frequency-Division Multiplexing (OFDM) and Multiple frequency-shift keying (MFSK) for an efficient transmission;
  • The use of up to 8 frequency channels optimizes the communication success rate;
  • The system uses an adaptive communication speed from 360bps to 23000bps that will automatically adjust depending on the traffic on the powerline.

Power line communication doesn't require the installation of additional control wires for control and monitoring. It uses the existing powerline cables.  This means important savings on the installation time, on wires and connectors and on maintenance of the lighting system.
