    en.wikipedia.org/wiki/Code-division_multiple_access

    Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.

    Multi-carrier code-division multiple access (MC-CDMA) is a multiple access scheme used in OFDM-based telecommunication systems, allowing the system to support multiple users at the same time over same frequency band. MC-CDMA spreads each user symbol in the frequency domain.

  5. Access Authentication in CDMA networks - Wikipedia

    en.wikipedia.org/wiki/Access_Authentication_in...

    Access Authentication in CDMA networks for telecommunications and computing provide network access for a mobile device. Specific methods such as CAVE-based Authentication (IS-95/1xRTT), and A12 Authentication are possible. The serving network provides the mobile device access authentication mechanism.

    AKA is not yet implemented in CDMA2000 networks, although it is expected to be used for IMS. To ensure interoperability with current devices and partner networks, support for AKA in CDMA networks and handsets will likely be in addition to CAVE-based authentication. Air interface support for AKA is included in all releases following CDMA2000 Rev C.

    cdmaOne network structure. The IS-95 standards describe an air interface, [1] a set of protocols used between mobile units and the network. IS-95 is widely described as a three-layer stack, where L1 corresponds to the physical layer, L2 refers to the Media Access Control (MAC) and Link-Access Control (LAC) sublayers, and L3 to the call-processing state machine.

    en.wikipedia.org/wiki/CAVE-based_Authentication

    CAVE-based authentication is a security protocol used to verify access in CDMA2000 1X, a type of third-generation mobile network system.The term "CAVE" stands for Cellular Authentication and Voice Encryption, which is the algorithm used to perform the authentication process. [1]
