ITU-T PHY Simulator

ITU-T PHY Simulator

ITU-T G.9960 is a physical layer (PHY) based on orthogonal frequency-division multiplexing (OFDM), which supports various fixed and wireless transmission media, such as coax, telephone line, power line, plastic optical fiber, and optical wireless communications, also known as LiFi.

Fraunhofer HHI – a leader in the field of communication technology – provides a comprehensive implementation of the ITU-T G.9960 physical layer. It can be used for several application, e.g., performance analysis or interoperability testing. The implemented algorithms have been tested and verified in laboratory and field trials.
