Benefits of Wi-Fi® Bridging

Bridging solutions connect multiple networks that use the same or different protocols by aggregating them into a single network. For example, an Ethernet-to-Wi-Fi bridging device receives incoming data from an Ethernet network and sends it back out via Wi-Fi and vice versa.

In general, Wi-Fi bridging is the fastest and easiest way to enable a Wi-Fi connection on an existing host machine. It is an optimal solution because the host machine gains Wi-Fi access without needing any new software or drivers and while continuing to use its existing communication protocol such as Ethernet, CAN or USB.

Convert Ethernet, CAN or USB to Wi-Fi Using a Single Interface Module

The WFI32 is a unique Wi-Fi MCU module that boasts reliable performance in harsh environments while offering multiple communication protocols. These features make it a great candidate for Wi-Fi bridging in industrial applications.
