The Matter standard so far provides for three network technologies for connecting devices: Ethernet, WLAN and Thread. However, manufacturers who use a different method can still make their devices accessible for Matter systems – with a bridge. It translates the signals of the foreign connection standard into the IP language of Matter. The bridge functionality can be built into a central unit (hub) or be located in other devices of the manufacturer. On one side, it communicates with Matter systems via Ethernet (LAN) or Wi-Fi (WLAN) and, on the other hand, establishes a connection to the manufacturer's technology. Typical are, for example, bridges for the radio protocol Zigbee or the professional lighting control DALI. For more information, see the background article on Matter Bridges.
