          • WiFi

          • The W-Lan modules were especially developed for usage in places, which are difficult to reach and far apart from each other. For example, it is possible through this technology to control the flow of fluids, which extend through out a huge area from a central place with an internet connection. It is also possible to record data from measurement systems in clean rooms, radioactive environment or places, which are difficult to reach.

            The Wireless Lan modules can be controlled from every device, which is wireless compatible, like PC, tablet or smartphone.
