Design And Implementation Of Indoor Distribution System In LTE Network

Due to the relatively weak indoor wireless coverage,the outdoor macro base station coverage alone can not meet the explosive growth of users' Internet traffic.With the acceleration of national urbanization process,a large number of high-rise residential buildings,large commercial centers and office buildings have been built on a large scale.Therefore,the construction of indoor distributed antenna system to solve the problem of indoor signal coverage has attracted the attention of telecom operators.The main work of this thesis is as follows.(1)The functions and technical parameters of passive devices,antennas,feeders and active devices used in indoor distributed antenna system networking are analyzed,which provides theoretical support for the design of indoor distributed antenna system networking.(2)The networking mode and design scheme of LTE indoor distributed antenna system are studied.(3)The implementation scheme of outdoor macro base station and indoor small cell covering densely populated area is proposed,which solves the indoor and outdoor coverage problem of LTE network and meets the needs of user coverage and network capacity of operators.(4)Taking a newly-built office building for indoor distributed antenna system coverage as an example,the engineering practice is carried out from the requirements analysis,organizational design,system simulation,engineering implementation,equipment opening into the network,engineering testing and acceptance process,and the expected design effect is achieved.
