Hello everyone, Lin Fei to answer the above questions, what is the meaning of cdma package monthly fee, cdma network many people do not know, now let's take a look!

1. Cdma is a communication technology. Its full name is code division multiple access. If translated, it is code division multiple access. It will be used for wireless communication. This technology allows all users to use all frequency bands together in the course of use, without considering the problem of signal collision. So this technology is still relatively advanced.

2. Different from gsm, the communication technology adopted by cdma is speech coding technology, so the call quality is relatively high. And in the process of practical application, this technology can well reduce some of the surrounding noise, so the effect of the call will be clearer. Cdma itself has a good authentication mechanism and uses code to distinguish users in the process of transmission, so it is rarely eavesdropped, which greatly enhances the security of communication.

3. A series of cdma, namely cdma2000, is a relatively new network that supports the operation of 3G networks. Cdma has many advantages and adds a lot of convenience to users. It makes calls clearer than gsm, so in noisy situations, such as ktv, the other person won't hear the music of your location during the call.

4. It is not easy to leak. First of all, its phone calls are not easy to steal. Secondly, even if it is stolen, decryption is also a very difficult thing, so the privacy of users has been well protected. Mobile phones using cdma technology have very little radiation and will not cause great harm to human health. The bandwidth capacity of cdma is very large, generally up to 153k, while similar gsm can only reach 56k. The communication band of cdma is also wide, and it has the function of multi-channel multiplexing, so the application rate of the network has been greatly improved.

5. The emergence of anything new is the result of people's needs, and cdma technology is no exception. With the development of science and technology, people continue to pursue higher quality wireless communication, so cdma technology arises at the historic moment. Cdma technology first appeared during World War II and was originally used to interfere with enemy communications. Later, after the update and development of Qualcomm, it became a commercial telecommunications technology and was launched in 1995. After some practical tests, its function has been recognized by many users, and then extended to other parts of the world.

At the end of this article, I hope it will be helpful to you.
