How does phone signal go through walls?

Any radio frequency can be blocked, or “jammed,” if a transmitter sends a signal at the same frequency, with enough power . But LTE turns out to be especially vulnerable, Reed’s group says. That is because the whole LTE signal depends on control instructions that make up less than 1 percent of the overall signal.

WiFi signals are a type of electromagnetic radiation, much like visible light. The electromagnetic waves that have a wavelength in the range of WiFi signals pass through walls just as easily as light passes through glass windows .

But weak, inconsistent, or poor-quality signals can happen for a number of reasons. Averse weather, interference from building materials or terrain, distance from your nearest cell tower, or network overload can all contribute to poor signal.
