The History of Mobile Phones – How did the cell phone come?

The idea for mobile phones was much longer than the technology that provides them. As the first landline lines were used, people came up with the idea to improve the convenience and flexibility of the new communication tool and bring them to new areas such as cars. First, mobile phones were just a little bit more than two-way portable radios, but as technology improved, the concept of mobile phones quickly improved.

Bell labs and Motorola to find out who can figure out the first viable mobile phones. Although Bell laboratories have installed innovative radio systems in police cars, these devices were too big to be able to carry anyone and it was really practical as a real mobile phone. However, in 1973, Martin Cooper, a scientist working for Motorola, successfully completed the first mobile phone call using a portable handset. The age of the cell phone was finally born and who called it? Nobody else than Bell Labs's rival, Joel Engel, who fought for competition in the invention.

In a few years, both Bell and AT & T have developed their own prototypes and set up in the first experimental areas. Chicago and Tokyo were the first cities in the world where they could use mobile phones, but their availability was extremely limited and new phones were only available to selected customers. For example, the 1979 Chicago-based trial company has only 2000 mobile phones sold

. By 1987, more than a million mobile phone users were alone in the United States. It seemed as if everyone needed a mobile phone and the big companies involved would have really hit their homes. However, there were difficulties. For example, in the United States, the FCC controls and distributes radio bandwidth for various purposes. Radio frequencies are limited and complete, so check out who is using the different parts. The area allowed by us to mobile phones was fast-frozen at 800 MHz. However, instead of giving more, they forced telecommunications companies to improve technology and use bandwidth more efficiently. By the end of the 1980s, this was accomplished, and the mobile phone age we know is now really starting. And the rest, as they say, history.
