IEEE 802.21d to Enable Multicast for Media Independent Handovers

The IEEE Standards Association (IEEE-SA) has approved a new 802.21d standard for local and Metropolitan Area Networks.


IEEE 802.21d extends the standard’s framework for improving users’ experience for mobile devices by facilitating secure, automated handover between IEEE 802® networks, as well as between IEEE 802 and cellular networks. It supports a secure Multicast Group Management capability applicable to Advance Metering Infrastructure (AMI) networks, where thousands of nodes require periodic configuration update, handover and re-keying in failover and failback scenarios. The standard is also applicable to home networking reliant on secure signaling and keying of a growing number of connected devices, as well as to service providers and operators by providing a means for secure and efficient device configuration and management.

“In our growing connected world, IEEE 802.21d has many stakeholders that can benefit by utilizing its framework to streamline secure multicast communications and realize cost savings over proprietary solutions,” said Dr. Subir Das, chair, IEEE 802.21 Working Group.
