2. 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.

3. CDMA2000 - Wikipedia

   en.wikipedia.org/wiki/CDMA2000

   CDMA2000 1X (IS-2000), also known as 1x and 1xRTT, is the core CDMA2000 wireless air interface standard.The designation "1x", meaning 1 times radio transmission technology, indicates the same radio frequency (RF) bandwidth as IS-95: a duplex pair of 1.25 MHz radio channels. 1xRTT almost doubles the capacity of IS-95 by adding 64 more traffic channels to the forward link, orthogonal to (in ...

4. 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.

   From the latest published version of the respective 3GPP2 technical standard (C.S0057-F), [5] the following table lists the specified frequency bands of the cdmaOne and CDMA2000 standards. [6] [7] [8]

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

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

   An alternative form of multi-carrier CDMA, called MC-DS-CDMA or MC/DS-CDMA, performs spreading in the time domain, rather than in the frequency domain in the case of MC-CDMA — for the special case where there is only one carrier, this reverts to standard DS-CDMA.
