The difference between your phone and walkie-talkies is the way their signals are transmitted. Cell phones send signals directly to a nearby base station, also called a cell site that relays your call to the person with whom you want to talk.
A walkie-talkie, in contrast, transmits a broad signal that can be picked up by any radio within range that is tuned to the same frequency.

A base station has an antenna that sends and receives your phone calls in the form of electromagnetic radiation or radio waves. As you move around your call gets transferred from one base station to another to maintain reception. Under the Hood Most cell phones have had the same basic components since their inception.
These familiar parts include the antenna, liquid crystal display, keyboard, speaker, microphone, and battery. The least familiar part of a cell phone to the average user is probably the circuit board.
The circuit board includes conversion chips that convert incoming digital signals to analog and outgoing analog signals to digital. It is responsible for coordinating the operations of your cell phone.
Evolution — A Review of the iPhone 4 Modern Cellular Communications When cell phones first became available relatively few people were using them, but today many people have given up their land lines and rely entirely on their mobile phone.
With millions of people constantly calling, surfing the web and texting, cellular carriers have had to continue to push the technology forward. People have become sensitive to the sometimes unsightly appearance of metal cell towers dotting the landscape so carriers have taken an artistic turn.
Instead of metal poles, towers are often disguised as clock towers, palm trees and chimneys. Another advancement is the development of micro cell sites. These micro sites are small pieces of equipment that can be attached to an existing structure like a light pole, providing coverage for an intersection and other specific spots.
Another new technology is the distributed antenna network. This is a limited network set up to provide coverage for a single structure such as an arena or a mall.
