What are the characteristics and advantages of CDMA technology?

Advantages of CDMA: 1. Large system capacity. In theory, when using the same frequency resources, the capacity of CDMA mobile network is 20 times larger than that of analog network. In actual use, it is 10 times larger than analog network and 4-5 times larger than GSM.

.

2. Flexible configuration of system capacity In a CDMA system, an increase in the number of users is equivalent to an increase in background noise, resulting in a decrease in voice quality.

However, there is no limit on the number of users, and the operator can make a compromise between capacity and voice quality.

In addition, users between multiple cells can be distinguished by different sequence codes according to traffic volume 3. Simple frequency planning, so different CDMA carriers can be used in adjacent cells. Network planning is flexible and expansion is simple.

4. Low network construction costs. CDMA technology simplifies the planning of the entire system by using the same frequency in each part of each cell, reducing the number of required sites without reducing traffic, thus reducing deployment and operating costs.

CDMA network coverage is large, system capacity is high, and fewer base stations are required, which reduces network construction costs.
