Base Station Coverage Forecast Model Research

At present,with the rapid growth of mobile users,the proliferation of user demand for mobile communication.Theimpact of the development of 4G and the trend of Cloud computing of Internet+.Base station as the communication infrastructure construction is facing a lot of demand.China's vast,the environment of provincial and municipal wireless propagation are differ in thousands ways.In the hilly region of city,for example,compared with the citiesin the plain area,its transmission environment is very different.The construction of the base stations are in different way.So if ignored on experience different terrain,landscape,building,the effects of parameters such as vegetation,will inevitably leads to the formation of a base station built by network or covered,quality problem,or base station is too dense,cause the waste of resources,which is the problem we need to solve immediately.In this thesis,we will mainly discuss the various factors that affect the network coverage and the adjustment of the variety parameters of a wireless network in order to achieve the best effect of coverage.Through the actual measurement and the compare of theory predicts,we can conclusion the date network coverage that suitable for the region.And to provide the reference for network planning in future.The parameters of the calibration prediction model can be better utilized and the base station construction in the region.In this paper,we first discuss the theory of radio transmission,then systematically summarize and analyze several common prediction models.The application of various models is introduced,and the coverage principle of mobile base station is explained.The final part selects three base stations with the same antenna height,same emission power and similar geographical environment in baotou area.The data is compared with the traditional model of the Olympic village model.The empirical formula that complies with the coverage of the base station in my area has a positive effect on the construction of the base station in my area.
