Indoor distribution system conducts the signal from base station inside the room to solve the blind covering indoors. It can solve the problems of the extending well and covering of the signal, and improve the quality of communication indoors. The system allot the signal into different rooms and channels scientifically in order that the signal can not affect each other. It is the complementary and extending of base station and Micro-cellular, and can not replaced by the base station and the repeater. It is the essential part of mobile communication in every big city.
The project is my job, when I work in Neracom. The main content of the project is based on the discipline of designing 3G indoor distribution system, choosing the right coverage approache to to meet the demand of the distributing of huge building and important zone. There are three approaches: distributed antenna system, leakage cable systems and hybrid option. It is mainly composed by three parts: signal source, the distribution system, coverage units.
