Thread is a low-power, IPv6-based mesh-based smart home protocol. Built on 6LoWPAN technology, it offers secure, reliable communication with minimal energy consumption.

It uses the same frequency band as Wi-Fi, but it creates a separate and dedicated low power network. Thread is based on the same 802.16 standard as Zigbee and like Zigbee,

Thread is a mesh network. By using Thread Border Routers, the devices have a degree of separation from the wider internet that might also help improve privacy and security.

Thread is integral to Matter standard, promising enhanced interoperability and simplified smart home ecosystems.
