WCDMA is being preferred more nowadays since it is newer, more advanced and transfers 3G data which is definitely faster than 2G data. It covers the area of GSM and is replacing it. The speed and the efficiency are more in WCDMA because of the technology used in this network, whereas the speed in GSM is less.
Which one is faster GSM or WCDMA?
The efficiency and speed are better in WCDMA due to the technology used in the network and the coding channel separating the data columns in the system. This helps to manage the communication channel well in the network and the communication is done faster than GSM. The efficiency and speed are less in GSM.
Is WCDMA same as 4G?
WCDMA is “a way of sending information in air (Radio Access Technology)” while 4G or 3G “a system t of mobile telecommunication”. In general, 3G system uses WCDMA ‘Radio Access Technology’ while 4G uses ‘OFDMA’ Radio Access Technology. For same thing, 2G uses GERAN Radio Access Technology.
Is GSM faster than CDMA?
Since its inception, GSM has evolved faster than CDMA. WCDMA is considered the 3G version of GSM technology. … Faster CDMA technologies exist, but US carriers chose not to install them and instead turned to 4G LTE to be more compatible with global standards.
Which is faster WCDMA or CDMA?
WCDMA stands for Wideband Code Division Multiple Access. It basically uses the same technology as that of CDMA but incorporates it into 3G. This works with GSM and EDGE to be used as UMTS and also resulted in higher internet speed. WCDMA signifies the leap from 2G to 3G and thus is miles ahead in terms of speed.
Is LTE better than GSM?
Summary of LTE verses GSM
GSM supports both cellular and data, whereas LTE is synonymous with high-speed wireless broadband technology that supports only data. This is why most of the new cell phones use LTE for high-speed internet access and rely on GSM for voice calls.
Is 4G and LTE the same?
LTE stands for Long Term Evolution. It’s a term used for the particular type of 4G that delivers the fastest mobile Internet experience. You’ll usually see it called 4G LTE. Using a 4G smartphone on Verizon’s 4G LTE network means you can download files from the Internet up to 10 times faster than with 3G.
Is CDMA used in 4G?
CDMA is a set of protocols used in 2G and 2G mobile communication networks. LTE is a protocol used in 4G broadband technology and has high-speed data access. CDMA uses Spread-Spectrum Multiple Access, SSMA for transmission. … LTE is now-a-day, a de-facto standard for 4G High-Speed wireless communication.
Why is CDMA preferred over GSM?
In CDMA technology, More security is provided as compared with the GSM technology because encryption is inbuilt in the CDMA. … The signal cannot be traced easily in CDMA as compared to the signals of GSM, which are concentrated in the narrow bandwidth. Therefore, CDMA phone calls are more secure than GSM calls.
How do I know if my phone is CDMA or GSM?
For Android users: Go to Settings ➤ System ➤ About Phone. Click on Status to look for an MEID, ESN, or IMEI number. If the device has MEID or ESN numbers, it’s a CDMA phone.
