| With the rapid development of modern mobile communication construction and increasingmobile users, in cities, outdoor areas have been basically achieved seamless coverage. Inorder to improve the quality of network, to enhance customer satisfaction, increase telephonetraffic, indoor coverage has increasingly become the focus of network optimization. Thereforeindoor distribution shall be made in most buildings so as to ensure good coverage of mobilenetwork.Background of product development:To unified design standard: The existing design proposals are lead to low efficiency onreview and construction since the variety version on device legend, frame and formatby different provinces;To improve design efficiency: the traditional way is design and drawing by VISIOsoftware, which function is not strong and comprehensive. Most of the design work,like drawing and calculation, are still have to be done by handwork;To evaluate the design quality objectively: Currently, it’s hard to predict the coverageeffect accurately after design completed.To manage the design drawings in a centralized way: As the original2G design drawingsisn’t systematic retention, there’s no corresponding2G construction plans to refer whileupgrade and rebuilding to3G or4G;Nowadays, the most popular design tools is AutoCAD (Auto Computer Aided Design),which is widely used in machinery, electronics, aviation, architecture, communications andother fields. This computer aided design software has good user interface, powerful functionand wide adaptability.This paper analyzed the existing indoor distribution design software: VISIO andTianyue, based on the research of Indoor Distribution Design System intelligent indoordistribution design software. The software is mainly used for solving the mobile wirelesscommunications system (2G,3G, WLAN, TETRA), especially in large-scale venues (such asbusiness building, tunnel) design problem of indoor coverage system, and also widely used inthe design of antenna distribution system design of buildings and tunnels. Indoor Distribution Design System is a tool designed for indoor distribution thatintegrated the chamber design plan, system, device number, label, project budget, theprediction of field strength and other factors, which will improve design efficiency greatly,and support for drawings standardization and digital management.This powerful software has highly integrated functions, easy operation, high efficiencyand flexible configuration. Start from the interface and function, planar graph routing andconnection function, simulation function, the function of elevator design and other aspects,the article will provide a detail of this software by following functions: antenna and feederconnected automatically, automatic generation of devices, intelligent drawing, automaticgeneration system, device automatic numbering, automatic calculation of level, replication thefloor level, the main connection and optimization, intelligent partition system, intelligentelevator design.Indoor distribution design software is a necessary tool for Indoor System Integratorand Communication Design Institute. The software supports multi-functions such as electricallevel auto calculation, device auto connection and feeder attenuation settings. The domesticmainstream indoor distribution design software all has their different characters, like Tianyue,infoCAD and VISIO. The Mobile Communication Indoor Distribution System is developedand improved base on the existing software, which includes the below advantages: reduceindoor distribution design workload; reduce designer requirements; reduce repeat design;reduce the possibility of human error; improve design efficiency; improve design pass rate;improve drawings standardization, maintenance and management; reuse design; automaticgenerate BOM and budget.As the development of new mobile network standard (such as LTE), and the need tosupport multi-network and multi-operators; the indoor distribution design software is anindispensable tool for indoor communication system construction and has to be upgradedmore or less. The Mobile Communication Indoor Distribution System is superior to othersbecause of considering the current and future network development. |
