Many new Matter devices will use Thread—an IP-based wireless mesh networking technology, designed for smart home devices.
Thread has the following key benefits:
- IPv6 based: Thread devices can join the same network as your other devices, and talk directly to each other and the cloud.
- Low-powered mesh: Built for IoT, Thread supports battery operated devices, with a mesh that delivers range and reliability.
- Speed: Low overhead, local connectivity, and mesh makes Thread devices extremely responsive.
Thread is developed in the Thread Group, which Google founded with other member companies in 2014.
Thread devices join users' existing home networks through a Thread Border Router. Just like a Wi-Fi router can bridge Wi-Fi and Ethernet devices into a single network, a Thread Border Router allows Thread devices to become part of users' networks.
Google devices like the Nest WiFi, Google Nest Hub Max and Google Nest Hub (2nd gen) have Thread radios built-into them and will act as Thread Border Routers when Matter launches in 2022.
An Interoperable Mesh
Thread devices and Thread Border Routers are built by a variety of device makers. We want to enable users to have an open, interoperable and strong Thread mesh in the home, regardless of the manufacturer.
As part of our new Mobile SDK, we've included Thread APIs in Google Play services that Android developers can use to join their devices to users' Thread networks.
Our Matter APIs in Play services will use these APIs as part of the setup process.
The Thread APIs can be directly accessed for Android developers who want to customize their Thread setup, or have other non-Matter use cases that utilize Thread.
To start using the Thread Network SDK in your Android apps, refer to our Thread Network SDK usage guide.
