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.

IEEE Standard for Low-Frequency (less than 500 kHz) Narrowband Power Line Communications for Smart Grid Applications
A worldwide standard for narrowband power line communications (PLC) via alternating current, direct current, and nonenergized electric power lines using frequencies below 500 kHz. Data rates of up to 500 kb/s are supported. The field of use includes Smart Grid applications. Coexistence mechanisms that can be used by other PLC technologies operating below 500 kHz are also included. These coexistence mechanisms may be used separately from the rest of the standard.
