– How does cellular signal reach me behind so many walls?

Question

I understand that radio waves pass through certain material (eg concrete walls), and hence we can receive cellular signals when in an apartment

However lets say I stay in a lower level of a high rise apartment (eg level 3 of a 50 storey tall building) – how does the radio waves penetrate so many walls to reach me? Does the amount of material not matter in this case?

Answer 1

They go around walls. Find a large, wide building and stand in the center. Your signal will be weak or none. Stand near a window or door, it’ll be stronger.
