Common questions Is CDMA the same as WCDMA?

Is CDMA the same as WCDMA?

Is CDMA the same as WCDMA?

The main difference between WCDMA and CDMA is that they are designed to work with different networks. WCDMA is a 3G technology designed to work alongside the 3G GSM network. CDMA, on the other hand, is a 2G technology that is a direct competitor to GSM.

Is WCDMA the same as GSM?

WCDMA is the 3G network that uses radiofrequency to transfer data in the form of calls, messages, or the internet which is also called UMTS. GSM represents 2G networks that were developed way before WCDMA and helps to transfer data through radio technology in the system.

What is difference between CDMA 2000 and WCDMA?

Cdma2000 is a 3G technology evolved from IS-95 CDMA technique. WCDMA is a 3G technology evolved from GSM technology.


LTE has an algorithm that is able to send large chunks of data via IP. The GSM system converts the data into a digital signal and sends it through two different time stamped channels at a rate between 64 kbps and 120 kbps. CDMA stands for Code Division Multiple Access. CDMA uses a multiple access mode of communication.

Why is WCDMA better than CDMA?

WCDMA is also better suited for accessing the internet and emails compared to the very slow CDMA. 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.

What phones are compatible with CDMA and GSM?

Newer model phones have been tested to work and be compatible with both software technologies – CDMA & GSM. T-Mobile and AT run their networks on GSM technology whereas Sprint & Verizon run on CDMA. Most phones are set up to work on ONE technology rather than both.

Which is better GSM or CDMA?

CDMA IS better than GSM. CDMA is a better technology(created by qualcomm) than GSM, BUT gsm is MORE wisely used, due to the fact that europe accpected that as their standerds for the polizie.

What is CDMA and how does it work?

CDMA stands for Code Division Multiple Access. It is a wireless communication technology that allows multiple people to use a single radio channel at the same time with little interference and very high security. Conventional communication systems transmit and receive on one constant frequency; CDMA “spreads” a radio signal…

Which carriers work on both GSM?

Both T-Mobile and AT use the GSM network, and therefore sell GSM-compatible phones. However, if you have a phone made in the last couple of years, you probably don’t need to worry about which carriers use GSM or CDMA networks since most newer phones work on both networks.
