Study On Three Networks Construction Mode Of Indoor Distribution System

At present, domestic communication industry is mostly a network pattern of multiple generation systems, which is run by China Mobile, China Unicom and China Telecom independently. The disadvantages of the abovementioned situation are repeated constructions of related infrastructures of communication system and wasting of resources. Consequently, focusing on core business operation and speeding up co-construction and sharing is an irresistible trend in order to enhance industry investment utilization ratio.The article will start from the interior distribution structure of the wireless signal and analyze all interferences existing in the main communication modes of each operator.The article mainly analyzes technical problems of interior distribution system’s co-construction and sharing. Building POI multiple system access by means of adding the combination of filter and combiner on the transmitter side, which makes the co-construction of the three networks possible. In addition, the strong and weak points of co-construction and sharing will be contrasted and analyzed through test outcomes in the process of practical constructions.
