摘要
从移动通信频率资源与市场需求的矛盾及如何提高频谱效率入手,从现有的成熟技术能力出发,结合蜂窝规划的演进过程,分析我国不同阶段所采用的蜂窝频率规划方法的不同特点和频谱效率,以及今后的发展趋势。
Starting with the analysis of the contradiction between mobile communication frequency resource and market requirement,and how to improve frequency spectrum utilization coefficient,from the view of current mature technical capability and the evolution of cell plan, it points out the future development trend and analyses the characteristics and frequency spectrum utilization coefficient of different cell frequency plans adopted in different period of our country.
