WLAN Mesh for automation networks

The WLAN 2100 wireless module from Phoenix Contact offers the new Firmware 2.6, in addition to access point and client, the WLAN Mesh operating mode.

WLAN Mesh enables the realization of autonomous, self-organizing ad-hoc networks that do not require a central infrastructure such as WLAN access points.

Simple planning, lower installation and expansion costs, as well as flexible adaptability to changing boundary conditions are some of the features that distinguish a WLAN mesh network. It is Layer-2 transparent, so that industrial automation protocols such as PROFINET or PROFIsafe can also communicate via the mesh network. The mesh routing protocol functions independently of the physical transmission medium. As a result, wired connections can be used in the mesh network in addition to wireless ones. As is usual with WLAN, communication is protected against manipulation and eavesdropping with WPA2 security and AES encryption.

WLAN mesh is used in automation applications where the usual star network structure of WLAN is not suitable – for example because different automation devices need to communicate directly with each other without cables or a central access point is not directly accessible.

The WLAN mesh function is also available on older WLAN 2100 modules via the firmware update. The firmware can be downloaded free of charge from the Phoenix Contact eShop in the Downloads section under http://www.phoenixcontact.com/product/2702535.
