Abstract


With the completion of the restructuring of the telecom operators , the new round of large-scale network construction officially began . In order to effectively implement the national energy saving policy , the Ministry of Industry and made ??a basic network resources sharing files . Consume a large amount of the cost of capital in the construction of basic network resources , indoor coverage system . Analysis , looking for an effective method Sharing indoor coverage system and coverage of the current carriers , operators can reduce repeated investment , reduce the difficulty of construction , maintenance and management to facilitate network operators . Multi-system multi- network construction and sharing in the indoor environment , and is thinking of building a network on the basis of their own characteristics in indoor coverage . Sharing current technical conditions , distribution system construction and sharing , and focus on the key consideration is the stray interference ( band interference) between the various systems . To effectively suppress stray interference , building and sharing of multi -play high isolation combiner or POI Combiner platform to achieve the necessary separation of the system up and down the line , in order to further improve the system isolation , to avoid the various systems mutual interference. In this paper , an organ in the Guangdong Province and multi- carrier networks compound Unified Access Case analysis should follow the principle of multi-system multi- network construction and sharing design indoor environment , given the design of a multi -play method , and that carried out design verification, the mentioned design is feasible . At the same time , the paper also summarizes the advantages and prospects of the proposed design , and analysis of its shortcomings , and a clear direction for future research .
