A Study On LTE FDD Indoor Coverage Design And Optimization

With the rapid development of domestic mobile communication technology in the era of LTE,coverage and optimization of regional signals have gradually become the core of construction of mobile communication network.In the era of LTE,indoor areas start to bear more business pressure.With complex internal structures,modern buildings have strong shielding and attenuating effects on the propagation of indoor wireless signals.The planning of indoor wireless distribution system is an important means of solving problems in the coverage of indoor regional signals,realizing the optimization of indoor signals and increasing user satisfaction.Firstly in the thesis,the development status of domestic mobile communication network and the planning significance of indoor distribution system are introduced.Key knowledge points including composition of distribution system,analysis of indoor coverage and planning of indoor distribution system are systematically teased.The single-station design process of this kind of projects is proposed innovatively.In addition,the realization methods of demand analysis,site investigation,indoor simulation test and each module's work are summarized.Disperse theoretical knowledge is combined with engineering design methods.Through the planning of LTE FDD indoor distribution system of project cases and according to single-station design process at a later stage,design points of each stage of projects and solutions to related problems are explained and relevant test data before and after improving the regional distribution system is compared to indicate that project planning has achieved expected effects.In the thesis,certain reference significance is provided for the implementation and optimization of current LTE indoor distribution system planning projects of the same type.
