How Do Mobile Phones Work?

The video tutorial explains how sounds are converted into electrical signals for landlines and how mobile phone conversations use microwaves for transmission. It highlights the advantages of microwaves over radio waves, such as higher frequency and smaller transmitters, but also addresses their limitations in diffraction. Base stations are introduced as a solution to these limitations, operating in cells to manage call transmission. The tutorial concludes with an explanation of how base stations function in both rural and urban settings, ensuring connectivity.
