As the communications industry, the construction of indoor coverage gradually highlight the importance and urgency. First, the share of traffic a great indoor coverage. According to the latest statistics, both in the 3G network or 2G network, the interior spaces are accounted for nearly 80% of the call volume. Secondly, from the perspective of communications services, said in a comfortable indoor environment, users spend waiting in the room in the process, preferring to use a rich variety of communications services. In order to better meet user needs, establish a good image, communications operators should be given to building indoor coverage considerable attention. Indoor coverage systems for indoor subscriber base, mainly to solve the mobile communication network within the building network coverage, network capacity, network quality and other issues. From the perspective of network coverage, and reasonable construction of indoor coverage and interference can be solved interior blind; from the perspective of network capacity, indoor coverage can spread the dense traffic areas, thereby reducing the pressure of the outdoor base station, to reduce outdoor The configuration and number of the base station; from the perspective of network quality, indoor coverage reduces the load on the outdoor system and, thus reducing the overall interference level of the network, improve the overall system capacity and quality. In a large low-rise buildings, underground shopping malls, underground parking and other environments, mobile communication signal is weak, the phone does not work properly, the formation of mobile communications blind and shadow; in the middle floors, as distinct from the surrounding base station signals overlap, caused by pilot pollution, frequent switching cell phone, or even dropped calls, seriously affected the normal use of the phone. In addition, in some buildings, although the normal phone call, but the user density, base station channel congestion, the phone line problems. Therefore, indoor coverage in the network construction plays an extremely important role. In this paper, indoor coverage and program evaluation projects related theory, based on the project construction program carried out assessment studies. Indoor coverage is given for the assessment of indicators, assessment methods and evaluation process. Specific objectives include assessment, evaluation operations, analysis and evaluation to assess the implementation summarize other aspects, combined with the characteristics of indoor coverage, select a specific target. Gives the target assessment, network assessments, site cost analysis process descriptions, and successfully completed a certain prefectures indoor coverage and repeater project construction program evaluation. Based on the results thesis, completed the city's building programs indoor coverage assessment, given the target assessment, network assessment, site description of the process of cost analysis and conclusions. Papers in the actual assessment work in the successful application shows that the proposed methods, processes and indicators are valid; regulate building programs in the assessment indicators, methods and processes for the construction of indoor coverage has a better program evaluation reference value.
