Mobile phones are portable phone terminals that can be used in a wide range. The full name is mobile phones or wireless phones. They were originally just a communication tool. In the early days, they were commonly known as "Big Brother" in China. Mobile phones were first developed from the field mobile phone manufactured by Bell Labs in the United States in 1940. Later, American Motorola engineer Martin Cooper invented the world's first commercial mobile phone in 1973.

In addition to typical phone functions, modern mobile phones also include more functions such as cameras, GPS, and Internet connections. They are collectively called smartphones. In terms of communication technology, modern mobile phones have also made significant progress. When Cooper made the world's first mobile phone call, he could use any electromagnetic frequency band. In fact, the first generation of analog mobile phones relied on different frequencies to distinguish different mobile phones for different users. The second generation mobile phone GSM system relies on extremely small time differences to distinguish users. Today, frequency resources are obviously insufficient, and mobile phone users are growing exponentially.

So the newer CDMA technology, which relies on different encodings to distinguish different machines, came into being. Mobile phones using this technology not only have better call quality and confidentiality, they can also reduce radiation and can be called "green mobile phones."
