Described the GSM network present situation, and introduced the wireless signal in transmission process fading. Through the building electromagnetic environment description, the article has analyzed in the room ¡°the isolated island¡±, ¡°the Ping-Pong¡± phenomena and so on blind spot. Through the field intensity carried on the scene DT test to the building, the article induces the weak signal link which covered in the room. And through simulation test to the room in the method, the article obtains the wireless transmission model in room to carry on the confirmation to this model. Afterwards, carrying on the analysis to the edge field intensity, and determined the edge antenna installment position. In the choice cover plan process, introduced each kind of supply oscillator use environment and determined the supply oscillator type. Explaining the distributed system, the optical fiber distribution system and so on several distributed ways. On the comparison, it had determined cover ways which the place was suitable. Through a series of improvements, the article has obtained the plan which is finally used, the antenna, the primary device, the skeleton line amplifier and so on. After completing the room covers, in room distribute system will inevitably change the big net original cover situations. This article has carried on the analysis to the signal divulging question. Through to in the edge field intensity computation and the building structure, the article proposed avoids method which reveals. Analyzed simultaneously the possible influence to depot rate lost call of base station produces and proposed the solution method. From three different aspects of falls in the speech, the article proposed influence of in room cover to the base depot voice dropout rate, and induced three kinds of reasons as well as the questions which should be paid attention to in the engineering design. Because between the room and outdoor, identical pilot signal can have the cut, in view of this question, the cut control and the realization of smooth transition method are induced.
