There are many types of mobile networks, but two of the most common are CDMA and WCDMA. So, what’s the difference between them? In this article, we’ll take a look at the features of each network type and help you decide which is best for you.
What is CDMA?
CDMA is an acronym for Code Division Multiple Access. It is a type of multiplexing which allows multiple users to share a single communications channel. Unlike other types of multiplexing, CDMA does not assign each user a separate time slot or frequency. Instead, it uses unique codes to identify each user. This makes CDMA particularly well-suited for use in mobile networks, where users are constantly moving around. CDMA is also less susceptible to interference than other multiplexing methods, making it ideal for use in areas with high levels of electromagnetic interference.
What is WCDMA?
WCDMA is a third-generation (3G) mobile phone standard. It is the most widely used type of 3G technology and is often referred to simply as 3G. WCDMA offers higher data speeds than previous generations of mobile phone standards, making it better suited for tasks such as streaming video and browsing the internet. WCDMA is an acronym for Wideband Code Division Multiple Access and is sometimes also known as UMTS, or Universal Mobile Telecommunications System. WCDMA is a type of CDMA, or Code Division Multiple Access, which is a method of multiplexing digital signals that was first developed for military applications. WCDMA uses a wider frequency range than other types of CDMA, which allows it to support higher data rates. WCDMA is used by many mobile phone carriers around the world, including AT&T and T-Mobile in the US.
Difference between CDMA and WCDMA
CDMA and WCDMA are both third-generation (3G) mobile telephone standards. Cdma2000 is the most widely used type of Cdma, while Wcdma is the standard used by most GSM networks. The main difference between Cdma and Wcdma is that CDMA uses spread Spectrum Technology (SST), while Wcdma uses Code Division Multiple Access (CDMA). SST is a technology that offers resistance to multipath fading, while CDMA is a multiple access technique that allows several users to share the same radiofrequency spectrum. Cdma2000 uses both SST and CDMA, while Wcdma only uses CDMA. Cdma2000 is, therefore, more resistant to multipath fading than WCDMA.
Conclusion
So, what is the difference between CDMA and WCDMA? CDMA networks are based on code division multiple access technologies, while WCDMA networks use wideband code division multiple access. This means that CDMA can handle more calls at one time because each call gets its own frequency, while WCDMA provides a wider bandwidth so that users experience less delay when streaming or downloading data. In North America, Verizon and Sprint both use CDMA networks, while AT&T and T-Mobile use GSM/WCDMA networks. If you’re looking for a phone that will work in the United States, make sure it supports either CDMA or WCDMA.
