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]
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]
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]
The OpenThread network simulator, a part of the OpenThread implementation, simulates Thread networks using OpenThread POSIX instances.[8] The simulator utilises discrete-event simulation and allows for visualisation of communications through a web interface.[relevant?][9]
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.[10][11]
