SIX Research Center - Sensor, Information and Communication Systems

The SIX center is engaged in research into communication and information systems and their components, operating in promising new frequency bands.

Emphasis is given to hardware solutions of systems, issues of communication and control protocols, securing transmitted information and related network technologies. Attention is paid to techniques that will enable the faithful and high-resolution presentation of transmitted information to users. The interactivity of the human-machine interface is gaining importance by the day.
