2. Code-division multiple access - Wikipedia

   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.

3. Multi-carrier code-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Multi-carrier_code...

   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.

7. Quadrature-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Quadrature-division...

   In CDMA or QDMA, a new user is simply allocated a new code and is ready to go. It may impose a slight load on the spectrum, but the system is so devised as to absorb a controlled measure of collisions and continue operations at a high level of quality of service.

8. Preferred Roaming List - Wikipedia

   en.wikipedia.org/wiki/Preferred_Roaming_List

   The Preferred Roaming List (PRL) is a database residing in a wireless (primarily CDMA) device, such as a cellphone, that contains information used during the system selection and acquisition process. In the case of R-UIM -based CDMA devices, the PRL resides on the R-UIM .

9. CDMA subscriber identity module - Wikipedia

   en.wikipedia.org/wiki/CDMA_Subscriber_Identity...

   A CDMA subscriber identity module (CSIM) is an application to support CDMA2000 phones that runs on a UICC, with a file structure derived from the R-UIM card. By porting the application to the UICC (Universal Integrated Circuit Card), a card with CSIM, SIM , and USIM can operate with all major cellular technologies worldwide.
