The Cell Phone Evolution
THE BEGINNING
Over a century ago, Alexander Graham Bell changed the way people communicated with each other. Back when he invented the phone in 1876, no one could imagine that over the next century, his invention would change the way societies interact and communicate with each other. Since the invention of the telephone, the process of communication has evolved.
According to the website Affordablephones.net, before the invention of the telephone, society had only the telegraph as a means of communicating over a distance (http://affordablephones.net/HistoryTelephone.htm). Since its invention, the phone has gone from only a few families owning one, to entire families owning several. Research in communication shows that throughout the years to the 1920’s mobile radio communications was used to send messages thru Morse code (http://www.unc.edu/~chelsea5/photoessay/). In 1921, Detroit Police used one-way mobile radios to communicate with each other. A message sent, via Morse code, to the receiver located in the police car. Patrol officers would stop at a wire-line telephone station to respond to the page (http://www.unc.edu/~chelsea5/photoessay/).
In 1924, Bell Laboratories made a major step towards the progress of communication by inventing the first mobile, voice-based, two-way radio telephone (http://www.unc.edu/~chelsea5/photoessay/). Society continued to utilize radiotelephone throughout the 1930s. The military continued to perform radio research for military purposes when World War II began (http://www.unc.edu/~chelsea5/photoessay/). It was not until 1943 that Dan Moble, and employee for Motorola designed the first portable FM two-way radio, the “Walkie-Talkie”, a handheld radio that was crucial for
