Reliable data transmission in Radio bands now secured

EES offers a large variety of telecontrol systems to transmit data over large distances about 10km or more. In particular wireless transmission over registration and free of charge use radio bands is an EES USP.

To secure the data transmission between each station, an AES based encryption can be activated. This symmetric process is executed by a pre-shared key, which can be generated dynamically by the parameterization software and can be different for each station.

Moreover a relaying of data can be carried out over each station, in case a line of sight is not available. By this analog and digital values as well as serial and IP based Modbus data can be exchanged reliably by this technique.
