CDMA (Code Division Multiple Access)
CDMA stands for Code Division Multiple Access, a digital cellular technology used primarily for mobile voice and data communication.
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.
