| With the rapid development of the mobile communication, the requirement of mobile communication network capacity and coverage becomes more and more serious. Only providing good outdoor communication services has been far from adequate to meet the demands, the mobile network is more with indoor coverage. To make up for short signal coverage of the base station to the construction, such as office building, convention center, star hotel, and so on, many major operators have constructed the comprehensive indoor wireless distribution system due to merely single indoor wireless distribution system is not meet the factors such as mobile subscribers, the high cost of networking and so on. This paper put forward some suggestions to improve indoor wireless communication network environment through the study of indoor comprehensive wireless distribution system.This paper investigates indoor comprehensive wireless distribution system of CDMA2000,WLAN,PHS. Firstly, this paper introduces the technology of CDMA2000,WLAN,PHS, and then analyze the Scheme design, design ideas, notices wireless distribution system. Take the Shengtian Huafu in Nanning city of Guangxi Province for example, the paper is elaborating an analysis of all the indexes of the indoor comprehensive wireless distribution system, field intensity estimate, Uplink/Downlink balance of the system, electromagnetic radiation protection and the requirement of construction process. According to the results of the test data of the system performance, this paper gives certain analysis of the standing-wave ratio (SWR) and interference, and propose suggestions of the manufacture and installation of the feeder, the selection and installation of the antenna and the selection of cell. By supply the discussions and actual examples support of study, this paper verifies the rationality and feasibility of indoor comprehensive wireless distribution system of CDMA2000,WLAN and PHS. |
