3G vs. CDMA: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 1, 2024
3G is a mobile communications standard offering data and voice services, whereas CDMA is a data channel access method used in some 3G networks.

Key Differences

3G, or third-generation, is a mobile telecommunications standard facilitating increased data capacity and speed. CDMA, Code Division Multiple Access, is a channel access method used in some 3G systems, allowing multiple signals to occupy the same transmission space.
