Marty cooper said that he was inspired by the TV series Star Trek. "When I saw Captain Kirk using a wireless phone, I immediately realized that this was what I wanted to invent."
Marty cooper told an interesting story about the invention of the mobile phone. The shape of the first mobile phone was actually the result of competition among five industrial design teams, but the simplest scheme was chosen. The original design was very small, but electronic system engineers had to cram hundreds of parts into it. The final mobile phone is five times as big as the original design and much heavier than the original design.
When Cooper got through the world's first mobile phone, he could use any electromagnetic frequency band. The first generation of analog mobile phones is actually to distinguish different mobile phones of different users by different frequencies.
