Thread is an IPv6-based, low-power mesh networking technology for Internet of things (IoT) products.[1] The Thread protocol specification is available at no cost; however, this requires agreement and continued adherence to an end-user license agreement (EULA), which states "Membership in Thread Group is necessary to implement, practice, and ship Thread technology and Thread Group specifications."[2]
Often used as a transport for Matter (the combination being known as Matter over Thread), the protocol has seen increased use for connecting low-power and battery-operated smart-home devices.[3]
Organization
[edit]In July 2014, the Thread Group alliance was formed as an industry group to develop, maintain and drive adoption of Thread as an industry networking standard for IoT applications.[4] Thread Group provides certification for components and products to ensure adherence to the spec. Initial members were ARM Holdings, Big Ass Solutions, NXP Semiconductors/Freescale, Google-subsidiary Nest Labs, OSRAM, Samsung, Silicon Labs, Somfy, Tyco International, Qualcomm, and the Yale lock company. In August 2018, Apple joined the group,[5] and released its first Thread product, the HomePod Mini, in late 2020.[6]
Characteristics
[edit]Thread uses 6LoWPAN, which, in turn, uses the IEEE 802.15.4 wireless protocol with mesh communication (in the 2.4 GHz spectrum), as do Zigbee and other systems. However, Thread is IP-addressable, with cloud access and AES encryption. A BSD-licensed open-source implementation of Thread called OpenThread is available from and managed by Google.[7]
Thread is a low-power and low-latency wireless mesh networking protocol built using open and proven standards.[citation needed] It uses 6LoWPAN, which is based on the use of a connecting router, called an edge router. Thread calls their edge routers border routers. Thread solves[how?] the complexities of the IoT, addresses challenges such as interoperability, range, security, energy, and reliability. A Thread network doesn’t have a single point of failure, and it has the ability to self-heal.[8]: 8
Thread is based on existing technologies in all its layers: from routing, packeting, and security to its wireless radio technology. Similar to Wi-Fi, with its broad range of devices, Thread is an open standard that is not tied to a specific manufacturer, which minimizes the risk of incompatibilities.
Thread’s IPv6 foundation is application-agnostic,[further explanation needed] offering product manufacturers the flexibility to choose one or more application layers to connect devices across multiple networks.[8]: 19–21 Developers can bring their apps, devices, systems, and services to market faster because they’re using the same set of tools available for the Internet.
The OpenThread network simulator, a part of the OpenThread implementation, simulates Thread networks using OpenThread POSIX instances, and provides visualization and management of those simulated networks.[9] The simulator utilises discrete-event simulation and allows for visualisation of communications through a web interface.[relevant?][10]
Use cases
[edit]In 2019, the Connected Home over IP (CHIP) project, subsequently renamed to Matter, led by the Zigbee Alliance, now the Connectivity Standards Alliance (CSA), Google, Amazon, and Apple, announced a broad collaboration to create a royalty-free standard and open-source code base to promote interoperability in home connectivity, leveraging Thread, Wi-Fi, and Bluetooth Low Energy.[11][12]
