If we look back, we will find that the concept of mobile phone appeared as early as 1930s, when Bell Laboratories, the largest communication company in the United States, began trial production. 1930, Bell Laboratories manufactured the first so-called mobile phone. But because of its large size, researchers can only put it on the shelf in the laboratory, and people will gradually forget it.

1973 in April, marty cooper, an engineer and technician of the famous American Motorola Company, invented the world's first civil mobile phone. When Cooper made 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.

The second generation mobile phone -GSM system distinguishes users with a very small time difference. At present, the frequency resources are obviously insufficient, and the number of mobile phone users is growing rapidly in geometric series. As a result, the updated CDMA technology, using different codes to distinguish different computers, came into being. The mobile phone using this technology not only has better call quality and confidentiality, but also can reduce radiation, which is called "green mobile phone".
