The Design And Application Of Ulti-Path Feasibility In The Indoor Environment

In recent years, as the global mobile communications customers, as well as the increasing number of wireless new business development, how to effectively use the limited indoor distribution of resources, improve system capacity, has become the third-generation mobile communication systems key issues. In this paper, WCDMA indoor coverage system combined multi-path feasibility study project, carried out relevant research and analysis.First introduces the characteristics of WCDMA,and WCDMA, CDMA2000and TD-SCDMA technology, three kinds of3G era of the mainstream system of internal quality were analyzed and compared. And from the standard stability, system performance, business to provide capacity, equipment, maturity, in terms of roaming capabilities of three major technology system to conduct a more detailed research and analysis.Study the system design process, different coverage of the indoor environment requirements. Respectively, PHS, WLAN, GSM and WCDMA system design specifications require a detailed analysis and research. Due to differences in indoor coverage system spec, how to find the multi-system Combiner balance is the actual network construction in a difficult and should fully understand the technical requirements of the various rooms subsystems, combined with its common features, to fully utilize the existing network material resources, construction of indoor coverage system combined way.In addition, from the capacity of the budget, power budget, communication model and source technical specifications requirements, etc., for PHS systems, WLAN systems, GSM systems, and WCDMA system, the signal sources of the feasibility analysis, obtained in different model-building for the signal source equipment selection to the principles and methods Combiner conclusion. All road and indoor distribution system, the technical indicators of the various components carried out a detailed analysis and research to build co-Road Indoor distribution system has laid a solid foundation.Finally, the vision for the future development trend of mobile communication technology.
