Study And Test Of 3G&PHS&WLAN Indoor Wireless Integrated Distribution System

With the continuous development of the wireless communication technology, many kinds of wireless communication system have been applied to practice. Instead of outdoor wireless coverage, indoor wireless coverage is drawing more and more concerns from both the provider side and the customer side. While different from the outdoor wireless circumstances, the indoor environment is more limited and complex, which makes it more difficult to solve the problem of inter-system interference. With the study of the integrated distribution system in the thesis, a successful experience of wireless communication network construction is presented.In this thesis, the project design of Indoor Wireless Integrated Distribution System is described. Firstly, the analysis of the inter-system interference principle is presented. Then, the analysis of the interferences in one building among WCDMA /PHS/WLAN has been focused on in this thesis, which include stray interference, obstruction interference and inter-modulation interference. After that, the system isolation requirement to suppression the interference mentioned above is analyzed in the thesis.Both the network distribution way and the system design parameter like network coverage and antenna transmitting power is analyzed in the thesis. Based on the above, the project design including Indoor Wireless Integrated Distribution System is successfully planned. Afterwards, the application example is applied, and the results of the inter-system interference test and system quality test has proved the feasibility of the project design.
