Save and secure wireless communication and sensing systems for time-critical scenarios are a key component for automation and control in industrial production and for automated transportation on streets, railways and in the air. We devise novel communication and sensing methods for 5G and 6G systems that are energy efficient.
The research group “Reliable Wireless Communication and Sensing” in the AIT Center for Digital Safety & Security operates a software defined radio frequency laboratory which allows the realization of highly-reliable wireless communication links in real-time as well as to perform localization and sensing tasks. Furthermore our lab allow to support the following development and research tasks:
- Test highly reliable wireless communications in time-critical scenarios (indoors and outdoors) using a software defined radio testbed.
- Design time-critical multi-channel signal processing on FPGA using open source tools such as
- Measure, model and emulate mobile communication channels between multiple moving nodes in non-stationary environment (indoors and outdoors),
- Utilize reconfigurable intelligent surfaces for advanced wave front control in the mmWave band,
- Perform multi-band transmission
- Site-specific radio channel modelling using numerical ray tracing tools.
EQUIPMENT
- 19 SDR transmitter and receiver for multiple-input multiple-ouput (MIMO) and for massive MIMO systems (URSP from EMERSON NI)
- field programmable gate arrays (FPGA) computation units for high-speed signal processing
- 3 Rubidium clocks for accurate phase and time-synchronization between multiple SDR nodes
- Antenna arrays to realize massive MIMO systems with distributed antenna groups
- Reconfigurable intelligent surfaces
- Semi-anechoic room for electromagnetic signal processing validation
- Operational frequency ranges (FR)1, FR2 and FR3: 1 MHz – 70 GHz.
