Why is CDMA2000?
CDMA2000 is a family of technology for 3G mobile cellular communications for transmission of voice, data and signals. It supports mobile communications at speeds between 144Kbps and 2Mbps. This gives higher data rate, greater bandwidth and better voice quality. It is also backward compatible with older CDMA versions.
What is the difference between Wcdma and CDMA2000?
CDMA is a 2G technology and is a direct competitor to GSM, which is the most widely deployed technology. As indicated by the word wideband, WCDMA uses a much wider bandwidth than that of CDMA. WCDMA uses frequency bands that are 5Mhz wide compared to CDMA where each frequency band is only 1.25Mhz wide.
Which CDMA2000 is a multi carrier technology?
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites.
What countries still use CDMA?

What is CDMA full form?
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.
How does WCDMA differ from CDMA?
The difference between CDMA and WCDMA is that CDMA is the technology used in 2G networks, while WCDMA is the technology used in 3G networks. WCDMA stands for Wideband Code Division Multiple Access. It basically uses the same technology as that of CDMA but incorporates it into 3G.
