How do the mobile cell phones work?

Mobile cell-phones work through radio waves transmitted from towers. In order to enable hundreds of people in the same area to talk on the phone at the same time, airspace is divided into cells, or smaller spaces. As you move from one cell to another, the phone automatically switches its frequencies.Without the cell technology, mobile cell-phones would be much like glorified walkie talkies, with everyone cutting in on each other’s frequencies.
