It introduces the implementation principle, technical characteristics and application scene on the POI system, it also introduces the LTE’s solution in indoor coverage project. Combined with the actual case project, it introduces the solution of operators to solve multi network coverage by using the POI, and realized the LTE dual way construction. At the same time, it analyzes the saving construction investment to solve the LTE dual way co-construction in indoor coverage by POI, provides a reference ex-perience for the selection of LTE dual way construction scheme.
