Code division multiple access CDMA Definition: Every call's data is encoded with a unique key, then the calls are all transmitted at once.
Every call data is encoded with a unique key, then the calls are all transmitted at once. CDMA is a channel access method used in various radio communication technologies, including cellular networks. It allows multiple users to transmit simultaneously over a single channel by assigning each transmission a unique code, making it resistant to jamming and eavesdropping. CDMA offers robust security features compared to earlier cellular technologies and has influenced modern wireless standards. Organizations implement CDMA security through encryption, authentication protocols, and secure device configuration. For example, a government agency might use CDMA-based secure phones for sensitive communications due to the inherent spread spectrum security advantages and additional encryption capabilities.
