For you, a cell phone is probably just a device that you or your friends use to keep in touch with family and friends, take pictures, play games, or send text messages. The definition of a cell phone is more specific: it is a hand-held wireless communication device that sends and receives signals by way of small special areas called cells. In 1973, an electronic company called Motorola hired Martin Cooper to work on wireless communication. Motorola and Bell Laboratories (now AT&T) were in a race to invent the first portable communication device. Martin Cooper won the race and became the inventor of the cell phone. On April 3, 1973, Cooper made the first cell phone call to his opponent at AT&T while walking down the streets of New York City. People on the sidewalks gazed at Cooper in amazement as he walked down the street talking on his cellular phone. Cooper's phone was called a Motorola Dyna-Tac. It weighed a whopping 2 i/2 pounds (as compared to today's cell phones that weigh as little as 3 or 4 ounces). After the invention of his cell phone, Cooper began thinking of ways to make the cell phone available to the general public. After ten years, Motorola introduced the first cell phones for commercial use. 34. What is a cell phone? 35. Who invented the cell phone and for what company did he work? 36.
