SUDIWI: Systematische Untersuchung der Störfestigkeit, Übertragungs- und Datensicherheit industrieller Wireless-Technologien

In many innovative applications in the area of industrial automation wireless technologies are more and more desired. Meanwhile, a great variety of commercial wireless technologies (Bluetooth, WLAN, ZigBee, nanoNET) are available which are offered as a great selection of OEM products.To avoid later disappointments technological limits should be considered early in the initial planning stage. A given wireless technology is not appropriate for all applications: a stationary data link in a large machine production hall demands other wireless requirements than a local robot assembling cell, where the mobile robot unit can reach velocities up to 60 km/h. In addition to these passive impairments active sources of disturbances have to be considered as well. These are parasitic machine emissions and unintentional or even intentional other wireless systems. The goal of this research project is the development of an assistance guide with two major issues:

• Firstly, enterprises of the industrial automation area, especially of small and medium size, shall be given help for the development of interference resistant wireless products.
• Secondly, the intended customer shall be offered guidance for installation and constraints for planning a wireless automation system.

Thus, the continuing industrial usage of wireless technologies will be placed on a reliable ground. As a necessary requirement systematic investigations of interference immunity, transmission, and data security have to be carried out. At this time only some non-systematic solutions are available.
