Evaluation Of Building Programs On Indoor Coverage And Repeater

As the communications industry, the construction of indoor coverage gradually highlight the importance and urgency. First, the share of traffic great for indoor coverage. According to the latest statistics, both in the 3G network or 2G network, the interior of the place has a market share of nearly 80% of call volume. Secondly, from the perspective of communication services, said in a comfortable indoor environment, users spend in the waiting room process, prefer to use a variety of rich communications services. In order to better meet user needs and establish a good image, communications, indoor coverage, the operator should give considerable attention to the construction.Indoor coverage system is the user base for the interior, the main settlement building mobile communication network coverage, network capacity, network quality and other issues. Coverage from the network point of view, a reasonable construction of the indoor coverage and interference can solve the indoor blind; from the perspective of network capacity, indoor coverage can also be dispersed to dense traffic areas, thereby reducing the pressure on the outdoor base stations, base station to reduce outdoor Configuration and quantity; from the perspective of network quality, reduce outdoor indoor coverage system load and, thus, reducing overall network interference level, to improve the system capacity and quality.This paper focused on indoor coverage projects for evaluation. Indoor coverage system is the user base for the interior, the main settlement building mobile communication network coverage, network capacity, network quality and other issues. Lower in large buildings, underground shopping malls, underground car parks and other environments, mobile communication signal is weak, the phone does not work properly, the formation of a mobile communication blind spots and shadow areas; in the middle floor, the signals from different base stations overlap around , Resulting in pilot pollution, frequent switching phones, or even dropped calls, seriously affected the normal use of mobile phones. In addition, in some buildings, while the normal phone call, but the user density, the base station channel congestion, the phone line difficulties.Lower in large buildings, underground shopping malls, underground car parks and other environments, mobile communication signal is weak, the phone does not work properly, the formation of a mobile communication blind spots and shadow areas; in the middle floor, the signals from different base stations overlap around , Resulting in pilot pollution, frequent switching phones, or even dropped calls, seriously affected the normal use of mobile phones. In addition, in some buildings, while the normal phone call, but the user density, the base station channel congestion, the phone line difficulties. Therefore, the construction of indoor coverage in the network plays a very important role.In this paper, indoor coverage and evaluation of projects related to building programs based on the theory of project construction program carried out assessment studies. Indoor coverage is given for the assessment of indicators, assessment methods and assessment process. Specific objectives include assessment, evaluation operations, analysis and assessment of the implementation of assessment summary and other links, combined with the characteristics of indoor coverage, select a specific target. Given the target assessment, network assessment, site cost analysis about the process. Successful completion of a repeater and city-building coverage and building programs for project evaluation.Based on the paper results, I have completed a city's indoor distribution system and repeater evaluation, given the conclusions of the target assessment, network assessment, process assessment and benefit assessment process . Papers in the actual ass-essment work in the successful application show that, the proposed method, process and index system is effective,norms the indicators, methods and processes in the post-assessment,it has a good reference value on the post-evaluation of indoor distribution system.
