World’s first device for wired, wireless and underwater communication

The HD-PLC Alliance is using Wavelet OFDM modulation for a next-generation powerline communication standard that operates over wired and wireless links and even underwater.

The technology has been adopted at the recent IEEE P1901c Working Group meeting for power line communication technology that can work even in constrained environments.

The baseline specification for the next-generation standard is capable of communication that uses not only power lines, dedicated lines, and coaxial lines, but communication in various media such as wired, wireless, and underwater and can be implemented in a single semiconductor device.

This also builds on the latest standard IEEE 1901-2020 standard used in buildings, factories, and social infrastructures around the world as a means of communication for energy and security management and equipment control.

The specification enables the communication band used to be reduced to 1/32 of that of the standard mode, thereby extending the frequencies from the conventional megahertz range to the kilohertz range and making it possible for a variety of media to communicate over even longer distances.

By using an antenna and applying the technology to wireless communication which uses low power transmission, secure short-range and high-speed wireless communication, which is capable of limiting communication range, could be available. The technology also helps enable underwater wireless communication, which was previously difficult.

The Alliance will hold a HD-PLC webinar on February 1, 2023 with a fourth generation HD-PLC chip and a solution of medium voltage grid automation.
