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 ...
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.
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.
In practice, 3GPP2 was the standardization group for CDMA2000, the set of 3G standards based on the earlier cdmaOne 2G CDMA technology. The participating associations were ARIB/TTC (Japan), China Communications Standards Association , Telecommunications Industry Association (North America) and Telecommunications Technology Association (South ...
also known as CDMA2000, the successor to 2G CDMA ; IMT-2000 CDMA TDD. also known as TD-SCDMA; IMT-2000 TDMA Single Carrier. also known as EDGE, an intermediate 2.5G technology; IMT-2000 FDMA/TDMA. also known as DECT; To meet the IMT-2000 standards, a system must provide peak data rates of at 384 kbit/s for mobile stations and 2 Mbit/s for fixed ...

Plan or attend holiday events where alcohol isn’t the main attraction “Parties are often centered around alcohol,” says Dr. Stephen Holtsford, medical director at Recovery Centers of America .
The EV-DO Rev. C standard was specified by 3GPP2 to improve the CDMA2000 mobile phone standard for next generation applications and requirements. It was proposed by Qualcomm as the natural evolution path for CDMA2000 and the specifications were published by 3GPP2 (C.S0084-*) and TIA (TIA-1121) in 2007 and 2008 respectively. [11] [12]
