Many people are not very clear about the distinction between CDMA and GSM. In fact, they are different wireless technologies used by large mobile companies, and the implementation of this technology depends on operators and regions. Next, let us learn more about the difference between CDMA and GSM through the following introduction:

CDMA mobile phones won’t work on GSM networks and vice versa. GSM offers the greatest speed and network capacity and is the most widely-used mobile network. CDMA and GSM are similar in quality, but GSM (more so than CDMA) gives consumers more choices in equipment.

GSM vs. CDMA mobile networks

Speed, quality and reception depend on equipment, location and service provider. Compared to CDMA, GSM is a more popular technology with availability in more than 200 countries worldwide. Both networks have their pros and cons.

Convenience

With CDMA, on the other hand, it is not as easy to transfer phones because consumers are identified based on whitlelists (basically, a list of devices that are specifically authorized to access the network), not SIM cards. Some CDMA phones do use SIM cards, but they are more for the convenience of use outside the US. Besides, CDMA only allows approved phones on its networks.

What’s more, back in the 1990s, the FCC decided to make use of both CDMA and GSM technologies, while Europeeans and most of the rest of the world agreed on GSM.

Security

GSM is working to overcome the perception that its networks do not offer the same high levels of security compared to CDMA, which experts say is difficult to detect even with targeted attacks.

Safety

CDMA devices emit much less radiation than GSM wireless phones. In fact, GSM phones are said to expose users to 28 times the radiation levels compared to CDMA phones. This may be because GSM emits wave pulses continuously and CDMA phones do not.

Worldwide use

CDMA is in use mostly in the U.S., Asia and Russia, whereas the GSM network is in virtually every country. CDMA phones also often have issues with roaming in some locations, but GSM phones rarely have that problem.

The difference between CDMA and GSM wireless phones is very obvious. You can also choose the wireless communication equipment that suits you according to your needs and actual conditions. If you want to know more about this, you can also visit our website www.suncomm.com directly.
