If you're asking yourself “How Does a Cell Phone Work?”  You're not alone.  When I finally broke down and joined the world of cell phone users, I too was curious as to how a cell phone works.  When I looked it up online, I found that I was not the only person asking “how does a cell phone work?”  Lots of people are curious. 

                Think of a cell phone as a combination of Alexander Graham Bell's telephone and Nikolai Tesla's radio.  Cell phones are wireless communication systems, similar to a radio but they are two way communication systems as well, similar to the telephone.  Like radios, cell phones rely on different radio frequencies to work.  The radio frequencies are regulated by the Federal Communications Commission of the United States because there are only so many radio frequencies that are allowed to be used by cell phones at any given time.

                Cell phones communicate and receive frequencies through cell phone towers and each tower is only allowed to have so many phone calls at one time.  If you live in larger city that means that it will take more than one tower to accommodate all of the cell phone users in that area.  You have probably noticed that cell phone companies like AT&T and Verizon have been boasting the amount of coverage that they have.  This is because they have been consistently building new towers over several years in order to increase their coverage.  The farther you are away from a cell phone tower, the worse reception you'll have. 

                So may you're wondering how you're able to talk on the phone while you're traveling.  Cell phone towers have the ability to bounce your call from tower to tower have you travel.  Your call will automatically bounce from one tower to the next one that is closest to you as your travel.  If you lose reception, that probably means that there isn't a tower close enough to you to pick up the call.  Each cell phone tower has a large amount of channels so that a lot of people can use them at the same time.  As I mentioned earlier, there are only a certain number of calls that can be on one frequency at the same time.  By increasing the number of channels available on each tower, more people are able to use that tower.

                One final thought on this subject.  If you have asked yourself “how does a cell phone work?”  Good for you.  This is an excellent question to ask if you want to protect yourself from people listening to your phone calls.  Can they?  Oh yes they can.
