• Unique Code Assignment: In CDMA, each conversation is encoded with a unique key, and then multiple encoded conversations are transmitted over a single frequency channel simultaneously. This is different from other technologies like GSM (Global System for Mobile Communications), which divides the frequency band into different time slots.

• Improved Voice Quality and Security: The unique encoding of each call in CDMA not only helps in managing more calls on the same bandwidth but also provides enhanced voice quality and security.

• No Fixed Limits on Capacity: Unlike GSM, which has a fixed maximum capacity per cell, CDMA's capacity is limited by the overall level of noise and interference on the network, making it somewhat more flexible.

• Less Prone to Dropouts and Interference: CDMA is less prone to experiencing dropouts and signal interference compared to other technologies, offering a more stable and consistent connection under various conditions.

• Used in 3G Networks: CDMA was a foundational technology for 3G cellular networks and set the stage for the development of 4G LTE (Long-Term Evolution) technology.

CDMA has played a significant role in the development of wireless telecommunications and is notable for its efficiency and the quality of service it provides in crowded and diverse network environments.
