The idea of mobile phones has been far beyond technology to provide them. As soon as the first landline came into use, people had the idea of improving the comfort and flexibility of this new communications device and moving it to new areas like cars. Initially, cell phones were little more than two-way portable wireless, but as technology improved, the idea behind mobile phones improved rapidly.
Bell Labs and Motorola Both participated in a dramatic competition to see who could invent first viable mobile phones. While Bell Labs has set up new radio stations in police cars, these devices were all too big for everyone to wear and were therefore ineffective as a truly mobile phone. However, in 1973, Martin Cooper, a scientist working for Motorola, managed primarily to call the phone using portable handsets. The age of the mobile phone was finally born and who did he call? No one but his contender in Bell Labs, Joel Engel, who had competed with him to create an invention.
Within a few years, both Bell and AT & T appeared with their prototype and the first trial was set up. Chicago and Tokyo were the first cities in the world where you could use a mobile phone, but their availability was very limited and the new phones were available only to a certain number of customer customers to begin with. For example, the 1979 study project in Chicago distributed cell phones to just 2000 customers.
The idea was like a threat. In 1987, there were over one million mobile phone users in the United States alone. It seemed like everyone wanted mobile phones and the major companies involved would have really brought home. However, it was difficult. For example, in the US, FCC rules and allocates radio bandwidth for different purposes. The radio range is limited and can become "full", so it is necessary to control who uses different parts of it. The area they received for mobile phones at 800 MHz was quickly crowded. But instead of giving up, they forced the electronic communications companies to improve technology and provide a more effective way to utilize the bandwidth they had. By the end of the 1990s, this was achieved and the phone age we currently know is going on. And the rest they say is a story.
