In order to better understand how interference works, it is helpful to first understand how mobile phones work.

This is how the phone works

In short, each mobile phone uses two different frequencies. One of these frequencies is used to send information, and the other frequency is used to receive information.

Regardless of the frequency used, the signal must first come from the phone and then sent to the base station. It is forwarded from the base station to the receiving mobile phone.
