摘要
针对密集城区4G网络覆盖存在的问题,分析和研究了4G网络深度覆盖的技术要求和部署场景;进而,采用分层分析法,从网络结构角度,对应建构了"布局层""补盲层""吸热层"及"室内层"的4G网络覆盖策略,并提出了分场景的"宏""杆""微""室"的综合解决方案;最后,以工程实例验证之,为后期密集城区的4G网络深度覆盖提供有益参考。
To solve the problems of 4 G network coverage in dense urban area,this paper analyzes and studies the technical requirements and deployment scenarios of 4 G network deep coverage. The method of stratified analysis is used to build 4 G network coverage strategy of＂layout layer＂,＂poor coverage layer＂,＂endothermic layer＂and ＂indoor layer＂. Furthermore,a comprehensive solution of＂macrocell＂,＂landscape tower＂,＂microcell＂and ＂indoor site＂in different scene is proposed. At last,a project case is presented to validate its feasibility,which provides a useful reference for 4 G network deep coverage in dense urban area.
