Thread 1.4 boost for IoT
The latest version of the Thread protocol aims to boost interoperability and extend network reliability, reach, and performance in the Internet of Things (IoT).
The formal release of Thread 1.4 specification includes an accompanying certification programme for applications. The enhancements in Thread 1.4, first shown in January, improve interoperability and boost network range, security, and reliability for advanced sensor networks as well as improve IoT devices’ energy conservation.
Thread uses open standards and is an agnostic network layer for IoT application layer technologies such as DALI+, KNX IoT, and Matter. For example, users can add an 1.4 updated Matter-enabled device to any existing Thread network connected by a Thread 1.4 Border Router, regardless of software or hardware ecosystem.
“There’s been an exponential increase of Thread-certified devices in homes and smart buildings globally since the major smart home platforms adopted Thread,” said Vividh Siddha, President of Thread Group. “From these real-world deployments, our members continue to discover inventive new ways for Thread to improve their end-customers’ experience. Now, device manufacturers can implement 1.4, and offer exciting new features, improved device performance, and stronger app integrations.”
With the 1.4 update, device manufacturers can begin implementing a mesh network where regardless of the brand, smart home platform, or mobile OS, adding an updated device or Thread Border Router, will join the existing network rather than create a new one.
Thread 1.4-enabled Border Routers gain a defined, standard path to the Internet and the cloud. This gives manufacturers the ability to add more appealing, dynamic features, such as window blinds that can self-adjust to weather changes, while end-users will have more reliable control, at home or off-site. Devices can also receive software updates and report diagnostics, which provides better technical support and lowers costs for installers.
Thread over Infrastructure enhancements allow Border Routers to use Wi-Fi and Ethernet connections to extend the Thread mesh network. This makes it easier to add new devices to the network, relocate an existing device, and for configurations to stay synchronised.
Thread devices at the edge of the network can be installed in far-reaching corners of or even on the exterior of homes and buildings with high reliability and robustness.
The latest version includes newly standardized methods for Thread devices to provide network configuration and status data, product developers and installers can gain more visibility into Thread networks. This enables more robust network performance for end users, advanced troubleshooting features for installers and developers, and the potential for commercial-grade network monitoring and diagnostics.
Thread’s commissioning at scale feature simplifies the process of wirelessly onboarding pre-installed devices in challenging locations, such as inside ceilings or walls. Instead of scanning physical install codes, Thread commissioning can be implemented over TLS (Transport Layer Security) with certificates. This authenticated commissioning can be done in proximity using a mobile device over a wireless connection like Bluetooth LE, making it suitable for professional installation and commercial building scenarios.
Thread 1.4 also includes maintenance updates that enable more robust operation and performance across Thread mesh networks. These new features will enhance the deployment and performance of Thread-enabled devices and networks, ultimately improving the user experience.
“During my nearly 10 years overseeing the certification program for Thread-enabled components and devices, we’re seeing unprecedented interest in the 1.4 enhancements,” noted Tom Sciorilli, Director of Certification for Thread Group.
“Now that the 1.4 certification program is taking applications, our members are eager to roll its benefits out to consumers, installers, and those responsible for smart building deployments.”
