Based On Three Nets Fusion Technology Of Mobile Communication Indoor Coverage Solutions Research

With steps of tri-networks integration, for further development of multiple services of 3G mobile communication, it is sticking point to provide good mobile signal coverage capability in buildings, especially in residential building and so on. However, the traditional mobile indoor distribution solutions can solve signal coverage problems of most buildings, but the user requirement of indoor signal coverage can not be satisfied for specific traditional indoor distribution system caused by complex construction structure or property company or other factors. It can be a compensatory method to induct the mobile communication signal by wire television cable for indoor signal coverage. Therefore, it has significant theoretical meanings and use values to research the indoor coverage solution of mobile communication base on tri-networks integration for improve the theory of mobile communication indoor distribution coverage and conduct the construction of mobile communication coverage system.The present paper research the methods of wireless signal for mobile communication based on wire television network, the method includes:the mobile communication signals transmits to signal combiner by cable, the combiner combine the wire television and mobile communication signal to one signal,the transmitted it on television network,the combined signal was split into television and mobile communication signal by splitter before arriving at terminal television network of and transmitted separately, it make receiving television signal and mobile communication signal indoor come true, The actual engineering solved some of the difficulties.The present paper respectively puts forward indoor signal coverage solutions based on GSM signal,WLAN signal and 3G(TD-SCDMA) signal accessed by CATV cable,and proves the practicability of the solutions by theoretical research and data analysis,provide theoretical reference and application value for implementing indoor signal coverage on the basis of tri-networks integration technology...
