Active RIS-Assisted Communication Prototype (3.5 GHz) @ Tsinghua

This prototype integrates an 64-element active RIS.

To overcome the “multiplicative fading” effect in RIS systems, we deploy a 64-element active RIS in the prototype to reflect and enhance the incident signals.

overview

Field test

We conduct field test based on the prototype and verify the performance of the active RIS.
