Slides are now available! On Tuesday, September 30, 2025, a consortium led by the University of Patras, in collaboration with the National and Kapodistrian University of Athens, Loctio, and ADVEOS, presented the results of the NAVISP EL1-063 activity “RIS-Aided Wireless Localization and Mapping (PRISM)”.

The PRISM project focused on the potential of Reconfigurable Intelligent Surfaces (RIS) for next-generation wireless localization and mapping. The main objectives included demonstrating RIS operation in real-world setups, evaluating performance using 5G signals, and implementing algorithms for RIS-aided ranging and angle of arrival measurements.

For the activity, the consortium built a hardware testbench featuring 1024 RIS elements operating at 3.5 GHz. This setup was tested in the anechoic chamber first, and then localization tests both indoors and outdoors were performed. 

The project was fully funded by NAVISP Element 1, supporting innovation and disruptive technologies across the Positioning, Navigation, and Timing value chain. The slides of the final presentation can be found here.
