Advanced~180 min

Learning Objectives

  • Describe the architectural choices in RIS demonstrators at sub-6 GHz, mmWave, and sub-THz bands
  • Characterize measurement campaigns and the dominant calibration challenges
  • Relate measured phase errors to predicted rate loss
  • Analyze the theory-practice gap between ideal models and real hardware
  • Design over-the-air test protocols for passive RIS panels
