What is “THREAD” and Why it Matters


About Thread

Designed for consumers and devices in and around the home, Thread easily and securely connects hundreds of devices to each other and directly to the cloud using real Internet Protocols in a low-power, wireless mesh network. The non-profit Thread Group is focused on making Thread the foundation for the Internet of Things in the home, educating product developers and consumers on the unique features and benefits of Thread and ensuring a great user experience through rigorous, meaningful product certification. Thread is backed by industry-leading companies including ARM, Big Ass Fans, Freescale Semiconductor, Nest Labs, Qualcomm, Samsung Electronics, Silicon Labs, Somfy, Tyco and Yale Security. Since opening its membership in October 2014, Thread has quickly grown to more than 160 members. For more information, please visit http://www.threadgroup.org.


Introduction and  General Characteristics

The Thread stack is an open standard for reliable, cost-effective, low-power, wireless D2D (device-to-device) communication. It is designed specifically for Connected Home applications where IP-based networking is desired and a variety of application layers can be used on the stack. These are the general characteristics of the Thread stack and network: • Simple network installation, start up and operation: The simple protocols for forming, joining, and maintaining Thread Networks allow systems to self-configure and fix routing problems as they occur. • Secure: Devices do not join the Thread Network unless authorized and all communications are encrypted and secure. • Small and large networks: Home networks vary from several devices to hundreds of devices communicating seamlessly. The network layer is designed to optimize the network operation based on the expected use. • Range: Typical devices in conjunction with mesh networking provide sufficient range to cover a normal home. Spread spectrum technology is used at the physical layer to provide good immunity to interference. • No single point of failure: The stack is designed to provide secure and reliable operations even with the failure or loss of individual devices. • Low power: Host devices can typically operate for several years on AA type batteries using suitable duty cycles.
