Understanding the Fast, Low-Power Mesh Protocol
Thread is the newest smart home wireless protocol designed specifically for Internet of Things (IoT) devices. Backed by Apple, Google, Amazon, and Samsung, Thread is a self-healing, low-power mesh network that is significantly faster than Bluetooth and uses less energy than Wi-Fi. Here is how it works.
How Thread Mesh Works
Unlike Wi-Fi, where every device must connect directly to your router, Thread devices talk to each other. If one device in the chain goes offline, the network automatically reroutes the signal through another device. This is known as “self-healing.”
Key Thread Device Types:
- Thread Border Router: Connects the Thread mesh network to your home Wi-Fi/Ethernet (e.g. Apple TV 4K, Nest Hub Max).
- Thread Router: Mains-powered devices (like smart plugs or light switches) that extend the mesh network range.
- Thread End Device: Battery-powered sensors that consume very little power and sleep when not in use.
