Thread is a wireless networking protocol that allow smart home devices to communicate with one another. Each device within a smart home can communicate with another device by using a mesh network. The Thread protocol use the 2.4 GHz radio frequency band to communicate with other devices.
Thread works similar to Wi-Fi and Bluetooth protocols but uses smart routing to determine how data move through the mesh network. If one device within the Thread protocol fail, the network will automatically reroute data through another path in what is known as a self-healing protocol. A person must use a border router to connect to the internet to a Thread protocol network.
How Thread Works in Smart Homes
A border router connect a persons Thread protocol network to the internet. Many individuals already own one of these routers as their smart speakers or smart media boxes may contains the border router within the device. Without a border router to connect to the internet and to a smart home application on a smartphone, the smart home devices wont be able to connect to the internet.
Additionally, devices that is plugged into a power outlet can also act as the routers for a Thread protocol network. These devices will extend the range of the Thread protocol by allowing them to communicate with devices that are further from the original Thread protocol devices. Thread is different than other smart home technologies such as Zigbee or Z-Wave protocols because Thread use native IPv6.
This means that the devices will be able to communicate directly with one another using internet protocol address. With Zigbee technology, the devices must use a coordinator to manage the network. With Z-Wave technology, devices will use different radio frequency to communicate with one another over longer distances but will use smaller networks than Thread protocol technology.
Thread protocol devices will use very little power to communicate with other devices within the network. Many of these devices will run on small batteries for several years. The devices will enter sleep mode when not in use to save power but will automatically wake up when a device within the network require an update from another device within the same network.
Matter is a standard protocol that works on the Thread protocol to allow devices from different smart homes to communicate with one another. For example, Matter allow devices from Apple, Google, Amazon, and Samsung smart homes to communicate with other devices from the same brands. However, Matter will use Thread protocol to communicate with smart devices that use very little power, such as sensors.
Devices that use alot of power, such as smart cameras, will use Wi-Fi to connect within the smart home. By combining Matter and Thread protocols, a person will be able to purchase a device that works with multiple brands of smart homes. This will eliminate the concerns of devices within a smart home only working with one brand of smart home devices.
There are many different type of devices that use the Thread protocol. For example, motion sensors, temperature sensors, and door sensors are all devices that use the Thread protocol but require very little power to operate. Smart lights and smart plugs is devices that are physically plugged into an electrical outlet and can act as routers for the Thread protocol.
Smart thermostats and smart locks use the Thread protocol to maintain a reliable connection between devices which the protocol is design to do. Low latency means that the protocol will allow for very little delay between the smart home device receiving a command and the device performing that command. A person can create a Thread protocol network by using a border router that is active within a smart home application.
Once a person confirms the border router is active, a person can add smart devices by scanning the QR code that is displayed on the screen. For devices with a weak connection to the Thread protocol, a person can purchase a smart plug or a smart light and place it between the border router and the device that is exhibiting a weak connection. This will extend the range of the Thread protocol.
In addition, a person should avoid placing the Thread protocol routers near appliances, such as microwaves as they will interfere with the 2.4 GHz radio frequency. To ensure that a Thread protocol network is strong throughout a smart home, a person should ensure that there are enough powered devices, such as smart plugs, located throughout the home to act as the networks router.
