What Radio Waves Can Travel Through and What They Cannot

WebMay 25, 2024 · 4G, LTE, and 5G signals are radio frequency waves. Like all radio waves (cellular, WiFi, AM/FM radio, satellite, etc.), obstructions can weaken and obliterate cell signal. This is especially true for 5G's high frequencies. Today, we’re looking at the top building materials that block RF signals and by how much. WebMay 10, 2024 · The answer depends on the construction and geometry of the metal object. Let us agree on radio waves including frequencies from 10 kHz. up to 405 GHz. I can construct a metal object that will allow radio waves to pass through it. It is also possible to create a metal shield that will block those same radio waves.

WebSo radio waves pass through walls because the molecules in the wall can't absorb them. The electrons aren't in the right orbitals and a single photon of that wavelength can't be used by the electron, so it's ignored.
