Terms related to 3G mobile communication include UMTS and WCDMA. WCDMA is one of the radio access methods for UMTS, which is a 3G network specification.
UMTS VS WCDMA | Difference | Comparison
- UMTS mobile technology, WCDMA is radio engineering.
- In the communication network, UMTS delivers a speed comparable to HSPDA, making it quicker than WCDMA. WCDMA operates at GSM speed, which is lower than UMTS speed. As a result, when choosing between WCDMA and UMTS, people choose WCDMA second.
- UMTS is a cellular technology, while WCDMA is one of its air interfaces.
- WCDMA is primarily utilized in all phones and, in some situations, paired with GSM or UMTS; UMTS alone cannot be used in communication devices.
- The area of coverage in UMTS is less, but if it is combined with WCDMA, While WCDMA is more area of coverage is more for WCDMA.
- Not CDMA, but GSM, is the primary channel. As an upgraded version of GSM that is available to everyone as a single protocol, UMTS is being developed. WCDMA relies on CDMA as a fundamental channel to facilitate communication and be effective.
- UMTS IS THE 3G specification for mobile communication and WCDMA is one of the proposed radio access technologies for UMTS.
- GSM, not CDMA, serves as the basic channel; UMTS is GSM's upgraded version, which is made universally available as a single protocol. WCDMA relies on CDMA as a fundamental channel to facilitate communication and be effective.
