CDMA

CDMA, or Code Division Multiple Access, is a method used in wireless communication that allows multiple users to share the same frequency band simultaneously. Each user is assigned a unique digital code, which they use to encode their data. When transmitted, these signals overlap but can be separated at the receiver because each code is unique. This technique increases network capacity, improves security, and reduces interference, making it efficient for many users to communicate at once without affecting each other's signals. CDMA is used in several 3G and beyond wireless technologies.
