Qualcomm, Boost Mobile, MetroPCS, Leap Wireless International Inc., Net 10, Sprint, Verizon, Cricket, and Alltel use CDMA technology.
A CDMA repeater is a device that extends the signal range for cell phone providers that use the CDMA technology. CDMA (Code Division Multiple Access) is one of the technologies cell phone companies use for their phone service. More information on CDMA is available here: http://en.wikipedia.org/wiki/CDMA

Code Division Multiple Access or CDMA cell phones utilize a technology that permits the use of several frequencies at the same moment to send and receive data and voice transmissions. CDMA is newer radio technology that is designed to compete with the older Global System for Mobile Communications (GSM) network. As a result, CDMA phones cannot use GSM cell towers. Another difference is that GSM phones use SIM cards while CDMA phones do not.
In short, no. WCDMA is designed to enhance GSM networks, even though it's technology is similar to CDMA, it uses different language.
WLL is Wireless Loop Link WLL use for CDMA Phone Technology

There is no such thing as a CDMA SIM card.CDMA is a technology which doesnt use SIM cards.And WCDMA is evolved from gsm and uses SIM cards for 3g.

Not Possible. The iPhone uses GSM radio technology. Alltel's network uses CDMA technology. They are incompatible. check out www.bowproducts.com
CDMA technology uses spread spectrum concept thereby giving users unique code to de-spread the information being sent to them. so CDMA is secure and occupies a large bandwidth of information compared to GSM technology.
no mts is 1600mhz cdma but nokia 2112 has only 800mhz cdma technology you can check also
No. At&t network uses gsm technology and verizo wireless uses cdma
