Changes to clarify how and when to encrypt header and payload information elements, update the interleaver design in order to eliminate some drawbacks in certain channels, a new PHY data primitive attribute so sub-band SNR data can be obtained from the PHY, modification to the frame counter size for security to make it consistent with IEEE Std 802.15.4e(TM)-2012, and adding a beacon attribute and change the zero crossing detector text are addressed in this amendment.

This standard specifies communications for low-frequency (less than 500 kHz) narrowband power line devices via alternating current and direct current electric power lines. This standard supports indoor and outdoor communications over low-voltage (less than 1000 V) (LV) and medium-voltage (1000 V to 72 kV) (MV) power lines and through associated transformers in both urban and long-distance rural applications. The standard uses transmission frequencies less than 500 kHz. Data rates will be scalable to 500 kb/s depending on the application requirements and network conditions. This standard addresses grid to utility meter, grid automation, electric vehicle to ch...

This standard amends IEEE Std 1901.2-2013 to incorporate corrections and clarifications
