This standard specifies physical (PHY) and media access control (MAC) layers of the medium frequency band (less than 12 MHz) broadband power line communication technology for smart grid applications (SGPLC) based on orthogonal frequency division multiplexing (OFDM) (e.g., FTT and/or wavelet OFDM). This standard coexists with IEEE Std 1901™-2010, IEEE Std 1901.2™-2013 [B1], and IEEE Std 1901.2a™-2015 [B2].1,2 The standard addresses the necessary security requirements that assure communication privacy and allow use for mission critical and security sensitive services and applications. This standard also defines the approach that is geared towards achieving an extended communication range in comparison with the existing power line communication technologies operating in similar frequency bands.
