对于CDMA数字网,业内运营者都想方设法在系统中增加用户数量,于是不断降低每位用户的费用。它采用数字通信技术之一的码分多址技术解决了这一问题。其优势体现在: 1.网络规划越来越简化。2.通话质量提高。3。用户通话时间延长。4.软音量和“软”切换。5.提高覆盖特性。6.保密性增强。7.高效的频带利用率和更大的网络容量。 For CDMA digital networks, industry operators are trying to increase the number of users in the system, thus reducing the cost per user. It uses code division multiple access technology, one of the digital communications technologies, to solve this problem. Its advantages are reflected in: 1. Network planning is more and more simplified. 2. Call quality improved. 3. User talk time extended. 4. soft volume and “soft” switch. 5. improve the coverage characteristics. 6. Confidentiality enhancement. 7. Efficient band utilization and greater network capacity.
