Indoor Planning And Design Of 4G Wireless Network

In indoor wireless network distribution system,the regionalization,high efficiency and standardization of network coverage have become the core problems of indoor 4G network coverage research.in the research and development of indoor distribution design software,the corresponding planning tools,the development of design scheme and so on are the basis of performance prediction,and the effectiveness of coverage is also closely related to the selection of indoor propagation model structure.Moreover,aiming at the use of the current indoor planning analysis software,the timely prediction efficiency and its accuracy become the basis of the actual design of the current personnel,and it is also the key content of the current planning research.Based on the communication model of indoor communication network,combined with the comprehensive research of the system,and taking the improvement of prediction efficiency and the application of new ideas and methods as the core,this thesis probes into the new backbone research and optimization methods.The main contents of this study include the following aspects:(1)The propagation empirical models of various common indoor wireless networks are compared and analyzed,and according to the establishment mode of ray tracking model,the feasibility,advantages and disadvantages of the model are determined,and the means and methods of modeling are analyzed.Based on the correction principle of the current indoor propagation model,the efficient simulation analysis of the indoor propagation empirical model is studied and analyzed,and the correction results are predicted and analyzed.(2)According to the design flow and planning principle of indoor spatial distribution software,the main optimization methods of its design are briefly introduced,and the problem of unreasonable planning in selecting devices and signal source parameters is put forward,the corresponding software coverage prediction function is used,and the algorithm of prediction coverage function is preliminarily improved.It is expected to improve the coverage prediction function and operation efficiency of indoor distributed software efficiently,and to improve the efficiency of user software and the satisfaction of software use,which is also one of the innovations of this thesis.
