What is difference between WCDMA and CDMA?

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.

What is the difference between WCDMA and CDMA 2000?

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

What is the difference between CDMA2000 and WCDMA in a 3G network?

CDMA2000 offered less 3G speed. WCDMA offered more 3G speeds.

What is the difference between CDMA and GSM technology?

The basic difference between GSM and CDMA is that the GSM is a SIM specific i.e. a mobile phone is identified in the network by the removable SIM inserted in that phone. On the other hand, in CDMA the network identifies a handset by the information stored in the internal memory and hence, its handset specific.

Which is better CDMA or WCDMA?

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 is difference between WCDMA and LTE?

In general, WCDMA is considered as 3G technology while LTE is considered as 4G technology. LTE provides higher data rates than WCDMA by achieving higher spectral efficiency. Also, LTE technology provide more flat architecture that is mainly focused on IP packet based services than that of the WCDMA.

Where is CDMA used?

Code Division Multiple Access (CDMA) is a sort of multiplexing that facilitates various signals to occupy a single transmission channel. It optimizes the use of available bandwidth. The technology is commonly used in ultra-high-frequency (UHF) cellular telephone systems, bands ranging between the 800-MHz and 1.9-GHz.
