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. 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.

   All forms of CDMA use the spread-spectrum spreading factor to allow receivers to partially discriminate against unwanted signals. Signals encoded with the specified spreading sequences are received, while signals with different sequences (or the same sequences but different timing offsets) appear as wideband noise reduced by the spreading factor.

5. Demand Assigned Multiple Access - Wikipedia

   en.wikipedia.org/wiki/Demand_Assigned_Multiple...

   Demand Assigned Multiple Access (DAMA) is a technology used to assign a channel to clients that do not need to use it constantly. DAMA systems assign communication channels based on news issued from user terminals to a network security system.

   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.

9. Time-division multiple access - Wikipedia

   en.wikipedia.org/wiki/Time-division_multiple_access

   CDMA's "cell breathing" characteristic, where a terminal on the boundary of two congested cells will be unable to receive a clear signal, can often negate this advantage during peak periods. A disadvantage of TDMA systems is that they create interference at a frequency that is directly connected to the time slot length.
