In the field of smart home, industry development has long been limited not by “connectivity”, but by the dilemma of “ecological fragmentation”.
From BLE, Wi-Fi to Thread, wireless communication technology has become relatively mature and can basically meet consumers’ diversified needs in terms of transmission rate, transmission distance, privacy, security and stability. It has essentially effectively solved the problem of “how devices are connected to the Internet”.
However, as the number of devices connected to the network increases and smart homes move from single-product intelligence to whole-house intelligence, new problems arise.
There are differences in the data expression methods, control logic, security policies and even network architectures of different brand manufacturers, making it difficult to form unified interactive semantics and collaboration mechanisms. This leads to a linear increase in the complexity of interoperability between devices, and eventually evolves into a smart home system that is seriously “ecologically fragmented” and difficult to maintain.
In this context, the value of the Matter protocol is highlighted.
It is not a “new protocol” simply superimposed on the existing technology system, but a unified standard for smart homes built on the application layer.
Matter protocol implements communication based on TCP/UDP transport layer and IPv6 network layer, and can adapt to various underlying network technologies such as Wi-Fi, Thread, and Ethernet.
Matter will use a layered architecture to separate different responsibilities and provide good encapsulation between different protocol stacks, so that application logic, data definition, interactive behavior, message encoding, security processing, and network transmission are decoupled from each other and work together.
In the layered architecture, the Application layer corresponds to the high-level business logic of the device, such as the function of turning on/off light bulbs and controlling colors in lighting applications; the Data Model layer defines the data model and actions of the application, and the application will use these data to interoperate with the device; the Interaction Model layer defines a series of interactions between client devices and server devices, and these interactions act on elements defined by the Data Model layer.
They allow various types of devices to have a consistent representation in the system.
This means that lamps, switches or sensors from different manufacturers are no longer isolated from each other in the system, but interact according to the same semantic model, fundamentally eliminating the “ecological fragmentation” problem that has long plagued the industry.
Once the user constructs an action (action) using the Interaction Model, the action (action) will be serialized into the specified compressed binary format in order to be encoded for network transmission. This process is handled in the Action Framing layer.
The encoded action frame is then processed by the Security Layer: the message is encrypted and a message authentication code is attached. These processes ensure the confidentiality and authenticity of the data between the message sender and receiver.
When the interaction is serialized, encrypted and signed, the Message Layer constructs the payload format using required and optional header fields, where the header fields specify the attributes of the message and logical routing information; when the payload is constructed by the Message Layer layer, an IP-based data transmission protocol (TCP protocol or Matter’s MRP protocol) is used.
After the other device receives the data, the data flow moves up the protocol stack, with each layer reversing the operations performed on the data by the sender to ultimately deliver the message to the application.
In addition, at the security level, the Matter protocol has raised security design to a mandatory requirement. Matter communication requires an end-to-end encryption mechanism based on DTLS/TLS, and implements device authentication and secure communication through the PASE/CASE session establishment process.
In terms of network structure, Matter also shows a high degree of flexibility.
Matter devices can run in Wi-Fi networks, and can also realize direct intercommunication between Thread and Wi-Fi devices at the IPv6 network layer through Thread border routers, thereby building a unified hybrid network of low-power and high-bandwidth devices.
However, no matter how advanced the protocol standard is, it will be difficult to truly change the industry structure if it lacks an engineering implementation path.
The key to the Matter protocol’s true large-scale application is whether it can be quickly integrated into actual products.
In this process, modular solutions have become a key bridge between “standards” and “products”.
For example, the HM-MT2401 launched by Huapu Micro is a Matter over Thread wireless communication module based on the 2.4GHz frequency band. Its design focuses on the balance between low power consumption and network stability.
By integrating Thread capabilities and providing PCB antennas and external antenna bases, HM-MT2401 can optimize power consumption performance while ensuring communication distance, and is suitable for typical smart home terminals such as lamps, switches, door locks and various sensors.
HM-MT7201 is another Matter over Wi-Fi wireless communication module. It is suitable for devices with high data throughput requirements. It can help devices directly connect to the Matter ecosystem while maintaining data transmission performance.
This type of module encapsulates complex protocol stacks, security mechanisms and network management capabilities at the bottom layer, eliminating the need for equipment manufacturers to implement the Matter protocol from scratch. It can significantly reduce the development threshold and speed up product launch.
In practical applications, relying on the multi-Fabric mechanism of the Matter protocol itself, smart home devices integrating Matter modules can be connected to mainstream platforms such as Apple Home and Amazon Alexa at the same time without the need to develop different versions of software systems. This ability has fundamentally changed the past product strategy of “binding a single ecology”, making smart home devices truly capable of cross-platform interoperability.
