If you are in the market for a new cellular carrier and mobile phone it is important that you are an informed consumer and know the differences between the two primary cellular technologies available, CDMA and GSM technologies.
What Is CDMA?
CDMA is an acronym for Code Division Multiple Access; it is a digital technology that uses what is known as "spread spectrum techniques." This means that the transmitted signal frequency varies deliberately. Allowing the signal to vary gives an output of more bandwidth than would be allowed if the frequency was not varied. CDMA has long been the standard used in the USA and has been known for its ability to provide better voice and data services than other cellular technologies on the market. Verizon and Sprint use CDMA technology.
What Is GSM?
GSM is the acronym for Global System for Mobile communications; it is a digital technology that assigns a fixed frequency every user on their network. GSM is the current standard in most of Europe, Asia, and has made rapid strides in gaining market share in the USA. GSM mobile phones use SIM card technology. AT&T and T-Mobile use GSM technology
