Wireless Local Area Network Planning Theory Research And Technology Based On Integrating Of GSM, TD-SCDMA And WLAN

With the development of wireless telecommunication and mobile service, great deal of wireless network has been built to provide application services. The cover emphases turned from broad outdooring to indooring, and the indoor wireless cover become the concern focus of telecom operations and subscribers. Different with outdoor space, the indoor space has many limits and become more complex, all these make it very diffcult to resolve the inter-system interfere problem in indoor wireless cover.This paper provides some experience for indoor wireless network construction based on the research of indoor wireless distribution system.This paper researches the feasibility of indoor wireless distribution system based on the theory of inter-system interference; researches the intra-network interference, inter-network interference and exo-network interference between GSM, TD-SCDMA and WLAN systems when they use the same indoor distribution system. Based on these researches, this paper provides the three network integration frequence plan model.This paper proposes the typical scenario three network integration capability plan model based on the capability estimate and the indoor audio model.Based on these models, the analysis on design parameters like signal coverage and antenna transmit power, the analysis on inter-system multiplexer and network organizing design, this paper proposes the GSM, TD-SCDMA and WLAN indoor distribution system solution design. And the design is verified by the interference test and network performance test of real projects.
