The Future of IoT is Here: Embracing the Matter Standard

Date: July 31, 2023

At AlphaNovel, we are always excited about advancements in IoT technology, and today, we would like to shine a light on one that is a real game-changer: Matter.

Formerly known as Project CHIP (Connected Home over IP), Matter is an open-source, royalty-free standard that aims to unify smart home devices and increase their compatibility with each other. Developed by the Connectivity Standards Alliance, formerly known as Zigbee Alliance, Matter involves big players such as Apple, Google, Amazon, and the Zigbee Alliance.

One of the significant advantages of Matter is its use of common networking technologies, such as Ethernet (Thread) and Wi-Fi, and its compatibility with popular smart home ecosystems like Apple's HomeKit, Amazon's Alexa, and Google's Weave. This unified approach enables seamless communication between various devices, which in the past, would typically require separate apps or specific ecosystems to operate.

Matter aims to create a more secure and reliable user experience for consumers and developers alike. With Matter, the goal is that any Matter-certified device will work with any Matter-certified network, increasing the simplicity, reliability, and flexibility of the smart home ecosystem.

Matter leverages a multi-layered protocol stack to enable seamless communication and interoperability between a wide range of smart devices. The protocol stack used by Matter (see figure) involves several well-established communication protocols, each serving different roles in the data communication process:

Thread: The Thread protocol is a low-power, wireless IoT protocol that acts as the network layer in the Matter protocol stack. It is responsible for establishing and maintaining the network connectivity between the smart devices. Thread is built on open standards for networking using IPv6 and 6LoWPAN, allowing for robust, secure, and efficient mesh networking.

IPv6: IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol, which provides an identification and location system for computers and networks. In the Matter protocol stack, IPv6 is used for routing packets across the network. Each device on the network is assigned a unique IPv6 address, facilitating the identification and communication between devices.

UDP: User Datagram Protocol (UDP) is a transport protocol used for the transmission of messages (or datagrams) over an IP network. Unlike TCP, UDP is connectionless, meaning it doesn't establish a direct connection between the sender and receiver before data transmission. This results in faster data transmission speeds but with less reliability. In the Matter protocol stack, UDP is used for sending and receiving messages between devices.

BTP (Border Transport Protocol): BTP is the application layer protocol developed specifically for Matter. It provides a common framework for devices to expose application-specific behaviors, such as turning on/off, reading sensors, etc., to other devices on the network. BTP also defines the security and data models used by Matter, ensuring secure and consistent communication between devices.

Together, these protocols work in harmony to provide a secure, robust, and interoperable networking solution for smart home devices, laying a solid foundation for the Matter standard and its promise of a unified smart home ecosystem.

At AlphaNovel, we are eagerly awaiting the final release of Matter. We believe this development will revolutionize the way we implement IoT services and smart home solutions, opening a world of possibilities for consumers and industries alike. Stay tuned as we continue to track and inform you about the latest developments in Matter and other IoT technologies.
