As a scientific and passive service, RAS requires protection from commercial services to observe the extremely faint celestial signals. As spectrum use for land, air, and space communications grows, protecting RAS operations from radio frequency interference is becoming more challenging. This report examines the impact of advanced technologies on radio astronomy, specifically car radar at 77 GHz, 5G and Wi-Fi device deployments at 6.6 GHz. These technologies are evaluated for their potential impact on Italian radio telescopes: the Radio Observatories of Medicina and Noto and the Sardinia Radio Telescope (SRT). Of particular concern is the potential threat posed by car radars to future high-density prospects, as well as the historical importance of the 6.6 GHz frequency for radio astronomical observation of methanol emissions from stars.ELETTRONICOenTechnical reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
