The Design And Optimization Of Signal In A Neighborhood By Combining Micro With Macro Station

With the development of times and people's living standard,the upgrading of mobile communication technology is important to meet people's demand.Taking residential area as a typical coverage scenario,problems such as weak coverage and interruption of network often occur.If macro stations are added continuously for supplementary coverage,it will cause many problems like resource reuse.Therefore,it is particularly important to supplement the construction of Micro Station.This thesis is based on residential signal coverage,the signal optimization design was studied to solve problems like weak coverage,blind area coverage and many other problems.Firstly,the reasons for the weak coverage in residential areas are analyzed.Starting from optimizing the signal of the base station.Then,attempting to introduce the macro-micro cooperative network mode to solve these problems.Secondly,constructing the coverage model to analyze the problems existing in the signal coverage of macro station,and putting forward to optimize the signal.By comparing the results of macro station optimization,the signal depth coverage cannot be completely solved.That is why a scheme of using micro-station equipment to solve the problems of weak coverage was proposed.Finally,the BOOKRRU devices were used to supplement the blindness in residential areas.After further test,the depth coverage of residential areas is optimized,which finally made macro-micro collaborative network.It is built to solve the problem of weak coverage,and to lay a foundation for the network construction.
