Under The Background Of All Business Technology Sharing Distribution System Design Study

The indoor coverage is an important part of the whole wireless network. To establish the indoor distribution system will be helpful to absorb traffic, enhance the user perception, as well as their stickiness. In the quadruple business development prospect, GSM, TD-SCDMA, TD-LTE, WLAN are with different coverage and business scenarios, and they will be coexist for a long time. As the indoor environment and space of the buildings are much complex than outdoor suroundings, it brings more difficulty to the design of multi-technology shared distribution system.In the background of China Mobile Group’s quadruple business, this paper will theoretically analyze the feasibility of the shared distribution system of GSM, TD-SCDMA, WLAN, TD-LTE. Through the study on the interference of many kinds of system and the analysis of different scenario demands, giving according distribution system combined structure.The paper gives a systematical plan of source and distribution system of multi-technology system; also make a systematical conclusion to the selection of device, antenna, combiner and the loader. The paper provides certain solutions to the introduction of new techno reform to the original system, and resources constrained scenarios.In this paper, we give the design of multi-technology common distribution system of particular scene, and then, make field strength test to the design. Through all above to system apically verify the feasibility and superiority of quadruple network.
