IEEE 802.15.4ac-2026

This amendment specifies modifications to the IEEE Std 802.15.4 medium access control (MAC) specification to specify mechanisms that address and improve user privacy. These mechanisms include randomized addresses, and exchanges that support session continuity. This amendment maintains backward compatibility with the base standard.

The standard provides for ultra low complexity, ultra low cost, ultra low power consumption, and low data rate wireless connectivity among inexpensive devices, especially targeting the communications requirements of what is now commonly referred to as the Internet of Things. In addition, some of the alternate PHYs provide precision ranging capability that is accurate to one meter. Multiple PHYs are defined to support a variety of frequency bands.

Amendment Standard - Active. Modifications to the IEEE Std 802.15.4 medium access control (MAC) specification to specify mechanisms that address and improve user privacy are addressed in this standard. These mechanisms include randomized addresses and exchanges that support session continuity. This amendment maintains backward compatibility with the base standard.
