This standard specifies Data Link layer for a hybrid Physical Layer (PHY) comprised of the PHY for Power Line Communications (PLC) as defined in the IEEE Std 1901.1-2018 standard and a PHY for Radio Frequency (RF) communication technology based on Orthogonal Frequency Division Multiplexing (OFDM). This standard is applicable for smart grid, Photovoltaic Energy System, Vehicle-to-grid (V2G) applications, Smart Home/Building and other data distribution applications. This standard defines an… read more interface to the PHY layers and a mechanism to switch data traffic between PLC and RF PHYs. The standard addresses the necessary security requirements that enable the use of this technology for mission critical and security sensitive services and applications. read less
