VoLTE高低频段覆盖能力研究

Study on the Coverage Ability of VoLTE High and Low Frequency

随着4G网络覆盖不断完善,4G终端不断成熟,VoLTE的建设和商用也逐渐启动。针对现阶段LTE 800 MHz和LTE 1800 MHz网络的建设现状,如何承载VoLTE网络是需要考虑的问题。从链路预算和仿真2个方面对VoLTE的覆盖性能进行了对比,详细分析了VoLTE和CDMA、VoLTE和LTE在覆盖性能上的差异,并提出了对应的建设策略。

With the continuous improvement of 4G network coverage and the maturity of 4G terminals,the construction and business of VoLTE are gradually starting.In view of the current construction status of LTE 800 MHz and LTE 1 800 MHz network,how to bear the VoLTE network is a problem to be considered.The coverage performance of VoLTE is compared from two aspects of link budget and simulation,the difference between VoLTE and CDMA,VoLTE and LTE in coverage performance is analyzed in detail,and the corresponding construction strategies are put forward.
