| Nowadays,indoor wireless communication networks widely exist in various different indoor environments and more and more attention has been paid to them by people.Various applications about them constantly appear and the application of indoor propagation models is one of them.People apply indoor propagation models in indoor wireless communication network planning and design,which provides tremendous convenience for the prediction of the actual situation.This paper just researches the application of two kinds of indoor propagation models---the empirical model and the ray-tracing model in indoor wireless communication network planning and design.The main work is as follows:1.For the empirical model,this paper mainly researches several common wireless propagation empirical models and explorates the correction of three wireless propagation empirical models and mainly explores the correction methods and correction process and also analyses the results of correction.2.For the ray-tracing model,this paper mainly researches the deterministic propagation model,which is represented by the ray-tracing model and mainly researches the Volcano ray-tracing model.Then,this paper also explorates the simulation and correction of the Volcano ray-tracing model and mainly explores the process of simulation,the method of correction and the process of correction and also analyses the results of the simulation and the correction.3.Finally,this paper also investigates and surveys the situation of encountering the problem of excessively slow running speed when using the function of the surface field strength prediction of the AIDP software and explorates the corresponding original algorithm of the function of the surface field strength prediction.Then,an algorithm improving method is put forward,which is proved effective.This method could commendably promote the running speed and get better user experience.This is an innovation point of the paper. |
