Research On TD-LTE Network Depth Coverage Technology And Its Applications In Gansu Mobile Networks

The fourth generation of mobile communication(4G)is one of the mainstream wireless communication technologies,which has been achieved rapid development recently.With the current 4G network construction and optimization,some problems have appeared including the existence of inadequate coverage and poor quality experience in some specific application scenarios.This thesis presents a comprehensive and in-depth research on 4G network deep coverage technologies and its applications in Gansu Lanzhou mobile networks.Firstly,major wireless communication technology principles are introduced briefly,followed are the analysis of evolution and development of wireless communication technology.This thesis focuses on the problem of network coverage and optimization in 4G network and discusses it emphatically.Based on the actual project requirements,this thesis analyzes the problems be solved in different application scenarios,and studies many issues such as parameter optimization,neighborhood optimization,dual carrier parameter optimization,weak cover optimization and power boosting,etc.The desighed and proposed strategy has been implemented in Gansu Molbie network,which shows effect quality improved in many kinds of application scenarios including reconstruction of the old urban areas,villages in the city,and universities areas,respectively.
