Transmissions
An interesting thing about cellphones is that they are really just radios; Really sophisticated radios, at that. But still just a cell phone. Cities and Towns are divided into cells. Each of these "cells" has a cell tower, providing service to all cellphones in that cell. A cellphone call in one cell will "jump" to the nearest cell tower, then to a normal land-line system, which works just like home phones

Understanding How It Works
You can understand how cellphones work by thinking back to walkie-talkies when you were a kid. These are some of the differences between cellphones and walkie-talkies:
 * Walkie-talkies can transmit about 1,000 feet (305 m) to another walkie-talkie before losing signal. Cell phones can transmit several miles or kilometers to the nearest tower due to transmitter wattage:
 * Only one walkie-talkie can talk at a time because in order to communicate, everyone must be on the same frequency; Cellphones communicate with each other on 2 frequencies: frequency "a" goes from x to y to z (x = p1's phone; y = cell tower and everything in between; z = p2's phone). Frequency "b" goes from z to x to y. This allows 2 people to talk at the same time.
 * Anyone can "piggyback," or tag on to a signal that isn't theirs, and listen to the whole conversation; Cell phone calls are much more secure due to Mobile Telephone Switching Offices (MTSO) which are connected to cell towers and land-lines to handle the signals and make sure they get to where they need to go.
