Earth's Radio Footprint: Assessing Its Detectability by Extraterrestrial Observers

To the point

Earth's radio emissions form a faint, limited-range beacon of human activity that could be detected by a nearby advanced civilization, though recognizing them as artificial would require a shared understanding of signal patterns and intent, and as digital technologies and fiber optics reduce leakage, detection from afar becomes increasingly unlikely.

Earths Radio Signals and Their Detectability by Extraterrestrial Civilizations - New Space Economy

Radio signals have been a defining characteristic of Earths technological era. Since the early 20th century, humans have been emitting a variety of radio signals into space, either intentionally or as a byproduct of communication, navigation, and broadcast systems. These signals continue to propagate through space at the speed of light, potentially reaching distant star systems. This raises a question central to the search for extraterrestrial intelligence (SETI): could an extraterrestrial civilization detect and recognize these signals as coming from an intelligent source?
