However, people put forward higher requirements on the quality and scope of communication. Since a large number of high-speed data and multimedia services, such as video telephony, gaming, are generally happened in a comfortable indoor environment. Only there is a large network of system which has capacity and good quality, that can meet user requirements of quality. So, technology of good indoor wireless coverage is widely used and paid attention more and more. The main way to solve indoor coverage is to build indoor coverage distribution system. The basic principles of indoor coverage distribution system is putting the outdoor signal through the wire introduced into the room, then sending out the signal through a small antenna so as to enhance the level of indoor coverage. Based on the theoretical analysis of indoor distribution system, this paper shows the implementation of the actual project on the indoor coverage distribution system. And some experience gained may be useful to similar projects. Key words£º3G; TD-SCDMA; Indoor coverage
