overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
CDMA (Code Division Multiple Access) is a digital cellular technology that allows multiple users to share the same frequency band simultaneously by assigning unique codes to each user. Developed in the 1980s and widely adopted in various mobile communications, especially in the late 20th and early 21st centuries, CDMA offers improved capacity, better signal quality, and higher security compared to earlier analog systems. It is a core technology behind certain 3G mobile standards such as W-CDMA.
