HOW CELL PHONES WORK!

By, De’Neal Gilliam

WHAT IS A CELL PHONE?

Originally call a “Cellular Phone” and many times also referred to as a mobile phone, or wireless phone is a are short-range communication devices that transmit to localized cell stations. They transmit information through radio waves (i.e. text messages and calls).

HOW DO THEY WORK?

Cell phones work on a concept called cell phone networking . Basically, cellular providers have huge networks of cell stations that are spread out across the world. Cell sites are usually most concentrated in highly populated areas and along highly traveled roads. So cell phone sites would be more popular in larger cities rather than small towns. Ever wonder why you lose your signal when you go out of town?

THE LIMITS OF CELL PHONES…

Cell phones are a relatively short-range form of communication. Most cell phones cannot transmit any further than roughly 8 miles. This means that a cell phone that is located farther than 8 miles away from the nearest cell site will not receive service. So using it underground or on a plane is a NO NO!
