At the Mobile World Congress 2026, held from 2–5 March in Barcelona, the 6G-SANDBOX project was hosted at Keysight Technologies’ demo booth.

Our Project Coordinator, Michael Dieudonne, together with Giovanni D’Amore, was present at the booth to answer questions about the project and to run the demo “High-Order MIMO Evaluation”, in collaboration with the CENTRIC Project and Nokia Bell Labs.

We were also honored to welcome the Smart Networks and Services Joint Undertaking (SNS JU) team and Ms. Erzsébet Fitori, Executive Director, Mr. Javier Albares, Head of 5G/6G Programs, Mr. Pavlos Fournogerakis, Deputy Head of Programmes and Ms. Chiara Mazzone, Programme Officer.

The demo received very positive feedback from visitors.

Giovanni D’Amore noted ‘As AI-RAN systems scale from SISO to Massive MIMO, generating realistic datasets for AI validation becomes increasingly challenging. In this demo, we show how this challenge can be addressed through a closed-loop RF setup that evaluates a customer’s AI algorithm under real channel conditions.’ Developed in cooperation with Nokia Bell Labs, the demonstration presented an assessment of an AI-based Channel State Information (CSI) compression model using 3GPP-compliant and ray-traced channels. The results illustrate how Keysight solutions help ensure consistent AI performance as RAN complexity and scale continue to grow.

In addition, visitors at the booth could watch videos about the 6G-SANDBOX platform and learn about the project’s outcomes. Thank you all for visiting and for showing interest to our project!
