The TD-LTE Indoor Coverage Scheme Design And Application

TD-LTE network is the main force to meet the demand of big data traffic.It is the bearer network of future converged communication.However the condition of establishing the competitive TD-LTE network is the wider,deeper and heavier cover.As the hot scene of data business,indoor coverage has become the key point of network establishment.The aim of this research is discussing how to enhance the indoor network covering and capacity in the form of three-dimensional networking using the distributed devices on the basis of outdoor TD-LTE network coverage and capacity under the condition of traditional Acer basement aiming at the current situation of TD-LTE network coverage.At first,by the research of basic electromagnetic wave propagtion theory,outside coverage project theory,equipment scheduling examples,fundamental of antenna,model selection and installation,this article gives the application methods of technology on related room points construction which provides the necessary theory basis for TD-LTE indoor wireless network coverage plan.Secondary,according to the technique characteristic of TD-LTE network and combined with the existing room point establishment model,this article proposes two solutions for indoor coverage aiming at the new construction or the transformation.Deeply analyze the advantages and disadvantages and suitable scene of different plans.In addition,analyze the difference in performance and interference problem during transformation of room points and gives the solutions.At last,by analyzing these five different scene,large gymnasium,middle-large size of resident,commercial building,transportation junction and other scenes,propose relatively indoor coverage design plan for different indoor scene.And make test after establishment.It can offer reference for TD-LTE indoor coverage designers and related engineers by verifying the feasibility of this plan.
