The IEEE has approved IEEE 802.21d for local and metropolitan area networks. This 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 advances the standard by supporting 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 signalling 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 utilising its framework to streamline secure multicast communications and realise cost savings over proprietary solutions,” said Subir Das, chair of the IEEE 802.21 working group.
Analyst firm Gartner has forecast that connected devices related to the IoT, excluding PCs, tablets and smart phones, will grow to 26 billion installed units by 2020.
“As we witness the advancement of smart grid and smart home technologies, there is clearly an increased need for standardisation in secure, multicast communications, and IEEE 802.21d is a proven and reliable solution for semiconductor, network equipment and smart device manufacturers, as well as service providers,” said Paul Nikolich, chair of the IEEE 802 local and metropolitan area network standards committee.
