Research On Huizhou Mobile TD-LTE Wireless Network Planning

With the evolution of communication technology and the arrival of the era of big data and Internet of things,the original 2G/3G network has become increasingly unable to effectively carry the rapidly growing demand for data traffic.Therefore,it is urgently needed to alleviate the pressure brought by the demand of big data network through data analysis and planning and construction of a reasonable 4G network.In this thesis,the TD-LTE network of Huizhou city was planned through phased analysis and demonstration of the Huizhou mobile TD-LTE network planning and network simulation,and the planning results were verified in the later construction and operation.This thesis mainly analyzed the current situation of the existing mobile communication network in Huizhou city,analyzed in detail the distribution of base stations of 2G/3G/4G network and the hot-spot traffic area,etc.,and carried out the coverage and capacity design of Huizhou mobile TD-LTE wireless network planning in stages according to the business distribution.The main coverage of Huizhou in the target area is calculated through the link budget.Meanwhile,by fully combining the 2G/3G/4G stock station structure,the quality station resource is shared and utilized,and the unreasonable site is planned and adjusted.In terms of capacity planning,the analysis and prediction of load carrying capacity of data hot-spot regional network are mainly used to obtain the planning results of new site and common site deployment.After the network planning is completed,the network simulation and the planning result verification of the planned site are carried out,among which the network simulation and the verification analysis are mainly carried out for the urban area.Through the verification process,the planning results were further evaluated.Combined with the results of network simulation,the construction scheme and investment estimation of 4G base station were carried out.
