WLAN Client Products

The MC-WLAN-Client-Adapter family provides devices with an Ethernet interface the ability to communicate wirelessly over an existing wireless network. Serial communicating client devices can be connected to a WLAN infrastructure via the serial interface of the MC-Adapter.All necessary parameters to establish the wireless connection is maintained in the MC-WLAN-Client-Adapters so the LAN client don't need additional drivers or configuration effort to use the wireless network. The typical application for the  MC adapter is the broad field of machine-to-machine communication via WLAN infrastructures. These include mobile installations such as forklifter or AGVs.

The presented 3 MC-Adapter, all based on the same processor platform and vary only in the different available interfaces.
