Matter over Wi-Fi / Ethernet

Matter over Wi-Fi / Ethernet refers to devices that use the Matter protocol over standard IP networking technologies such as Wi-Fi or wired Ethernet.

Unlike Thread, these technologies can transmit significantly larger amounts of data, making them suitable for devices that require higher bandwidth.

However, this capability comes at the cost of higher power consumption, which means Wi-Fi and Ethernet are typically used only in devices with a constant power supply.

Typical Devices Using Matter over Wi-Fi

Devices that require continuous data transmission or higher bandwidth usually rely on Wi-Fi or Ethernet instead of Thread.

Examples include:

Security cameras
Video doorbells
Multimedia and streaming devices
Smart TVs and entertainment systems

These devices generate significantly more network traffic than sensors or switches, which is why low-power mesh networks like Thread are not suitable for them.

Network Load and Wi-Fi Capacity

Wi-Fi networks can be compared to highways. Even if each device transmits only a small amount of data, a large number of simultaneous connections can lead to congestion, delays, and reduced network stability.

This becomes especially noticeable when using basic consumer routers that were not designed to handle many connected devices.

In smart homes with dozens of connected devices, proper network planning becomes increasingly important.

Advantages of Ethernet

Ethernet can be compared to a railway network. It is less flexible because devices can only connect where physical cables are installed, but it provides stable bandwidth and predictable performance.

Unlike Wi-Fi, wired connections are far less prone to congestion or radio interference.

For installations with many high-bandwidth devices, Ethernet remains one of the most reliable networking solutions.

Importance of Network Infrastructure

The quality of the network infrastructure plays a critical role in the performance of Matter devices operating over Wi-Fi.

A basic ISP-provided router may struggle to handle many simultaneous connections, while higher-quality access points can support significantly larger device counts with greater stability.

In simple terms, a low-cost router can be compared to a narrow dirt road that becomes congested under heavy traffic, while professional networking equipment behaves more like a well-designed system of high-capacity highways.

Practical Considerations

For most households, a small number of Matter devices using Wi-Fi will not cause any problems.

However, as the smart home system grows and the number of connected devices increases, it becomes more important to consider network capacity and infrastructure quality.

In larger installations, it may be beneficial to move high-bandwidth devices to Ethernet or distribute network load across multiple access points.
