What Does Code Division Multiple Access (CDMA) Mean?
Code division multiple access (CDMA) is a digital cellular network standard that utilizes spread-spectrum technology. This technology does not constrict bandwidth’s digital signals or frequencies but spreads it over a fully-available spectrum or across multiple channels via division. Thus, there is improved voice and data communication capability and a more secure and private line.
Techopedia Explains Code Division Multiple Access (CDMA)
CDMA technology was initially used in World War II military operations to thwart enemy attempts to access radio communication signals. In the early 1990s, Qualcomm introduced the possibility of using the same concept with publicly-available cellular network technology. During this time, an alternative mobile networking arena digital standard gained traction, proving to be a challenge to CDMA proponents. Despite adamant negativity and discouragement from prominent industry figures, CDMA’s supports successfully convinced these leaders to consider, use and eventually accept the newly introduced CDMA standard.
