Why do my cell phones get zero signal but then have full bars after relocating just 6 inches away?
Radio waves when emitted bounce off of objects. In certain spaces, you can be in just the right place where you are receiving the same radio signal bounced off of several different objects (and even directly from the source). When this happens, they can interfere with each other, causing this to …
The Short Answer
Radio waves when emitted bounce off of objects. In certain spaces, you can be in just the right place where you are receiving the same radio signal bounced off of several different objects (and even directly from the source). When this happens, they can interfere with each other, causing this to happen. It is called multipath interference: _URL_0_
