Q. In context with Mobile telecommunication, what is the full form of CDMA?
Answer: Code Division Multiple Access
Notes: The correct answer is "Code Division Multiple Access." CDMA is a digital cellular technology used for transmitting data over radio waves. It allows multiple users to share the same frequency band by assigning unique codes to each user, enabling simultaneous communication. This technology was developed in the 1940s by Claude Shannon and later adapted for mobile telephony in the 1990s, importantly improving capacity and efficiency in mobile networks.
