Nessum

Nessum, previously HD-PLC (short for 'High Definition Power Line Communication'), is a communication technology standardized by the Institute of Electrical and Electronics Engineers (IEEE). It is standardized as IEEE 1901-2020. The standard is to be used to communicate data over wired and wireless media using high frequencies between ~500kHz and ~56 MHz bands. The Nessum Alliance is the certifying body for compatibility between Nessum-based communication devices.
