Invention and History of Cell Phone
The first cell phone was invented in 1973 by Dr. Martin Cooper of Motorola. He was born on 26 December 1928 in Chicago, an American who worked hard to create the world’s first cell phone through which anyone can talk. Because of his hard work today, he is called the father of cell phones. He completed his graduation from The Illinois Institute of Technology (IIT) of Chicago with a degree in Electrical Engineering(1950). He worked in the US Navy and participated in the Korean War which is one of the most significant points in his career. He earned his master’s degree in 1957 and then went on to work at Motorola Systems.
The first cell phone in the world was named the Motorola DynaTAC 8000X which was a bulky device that weighed over 5 pounds (2 kg) and had a battery life of 30 minutes of talk time or 24 hours of standby time.
It wasn’t until 1990 that cell phones came into existence with lithium-ion batteries. Before that time, all phones had batteries made from lead acid or nickel metal hydride chemistry. This change made it possible for companies like Nokia and Motorola to mass-produce devices with smaller batteries and thus more people were able to buy them.
Moreover, cell phones have become popular in the mid-1990s and the early 2000s, and maximum people either have a cell phone or have used one. Occasionally, in a cellular phone or a mobile phone, the technology in the phone enables the user to use the phone’s numerous functions no matter where they are.
