Thread, a mesh networking protocol, connects low-power smart home devices and is one of the underlying technologies of Matter. It works similarly to Wi-Fi but requires less power, allowing it to be used for devices that need to connect intermittently and have limited bandwidth needs.
Thread operates on the 2.4-GHz spectrum using the IEEE 802.15.4 radio technology, which is also the basis for other protocols like Zigbee and WirelessHART. Thread devices can create a mesh network, share encrypted data, and communicate without configuration or management from the user's side.
The Thread protocol has several advantages, including low power requirements, low latency, self-healing networks, no proprietary hub required, scalability, AES-128 encryption, IPv6 support for direct device addressability using IP addresses. However, it also has some limitations, such as high-bandwidth devices not being able to use it, limited support for the latest version, range and number of devices still limited, old Thread devices often unable to be updated to new versions, and a Thread Border Router required to connect to the internet and cloud services.
Thread Border Routers are necessary to connect the Thread mesh to Wi-Fi, Ethernet, or any other home network. These routers also act as Matter controllers in many setups. Devices from various manufacturers can create their own low-latency meshes using Thread, with no proprietary hub needed.
The development of Thread began in 2011 by Nest (now Google) and has since been developed and adopted by several prominent companies like ARM, Samsung, Google, Qualcomm, Apple, and Amazon. New versions of the specification are released every couple of years and are backward compatible, but not all devices can be upgraded to the latest version.
Thread supports various application layers, including Matter, which it enables devices to communicate with each other in a unified way. Thread also offers credential sharing, allowing networks formed in different ecosystems and using different Thread Border Routers to form one big mesh. However, manufacturers need time to adopt the latest version of the specification and go through certification.
In comparison to Zigbee, another protocol based on the same wireless technology, Thread has lower latency and can seamlessly integrate with existing IP-based networks without a proprietary hub.
