Research And Implementation Of Antenna Coverage Simulation Function In Indoor Distribution System Based On Objectarx

In recent years,as the popularity of 4G network has been greatly improved,the business of voice,HD video communication and mobile terminal data transmission has also increased rapidly in indoor wireless environment,and the coverage requirement of indoor wireless communication is becoming more and more important.The software of the indoor distribution system is a designing tool for the effectively planning of the coverage effect in the indoor environment.Using the software to simulate indoor complexing environment,simulating of the coverage scheme,predicting of indoor network designing performance and planning of indoor construction are the basis cores of planning and designing.This paper focuses on the development of ObjectARX based on Auto CAD system,and builds a model for antenna coverage prediction and simulation in the indoor environment,and achieves important assessment of indoor environment by obtaining coverage and other important information.This paper first introduces the background knowledge of the indoor distribution designing software,and the related technology of Auto CAD system based on the development of indoor distribution software,then the software antenna power calculation function,the antenna coverage prediction function and drawing function of the derived demanding analysis are represented.According to the requirement analysis,the overall architecture of the software is given,and the functional modules are subdivided.The functional definition of each functional module and the various interface definitions of modules are given.On this basis,the core function class diagram is given,and the key class method and core service flows are described.Finally,the function test of the software is carried out.At the end of this paper,the summary of the full text work is given,and the future research direction is pointed out.
