摘要
小区覆盖作为室外宏站覆盖的补充,一直是解决居民区深度覆盖的重要方式。近年来,受限于投资和业主沟通等问题,在尝试了草坪灯布放天线点位和室内布放点位等方法后,采用楼间对打被证明是效果最好的一种,现已成为小区覆盖的主要建设方式。本文根据小区覆盖中日常天线的设置方法提出了一种自动化算法,用来判定需要的天线数和下倾角设置。该算法既可以对已有的方案进行校正,也可以在后续的建设中给设计人员提供依据。
As a supplementary part of outdoor macro station coverage,community coverage has always been an important way to solve the deep coverage of residential areas.In recent years,limited by the problems of investment and owners'communication,after trying to arrange antenna points for lawn lamps and indoor points,it has been proved to be the best way to use inter building fi ghting,which has become the main construction mode of residential area coverage.In this paper,according to the daily antenna setting method in cell coverage,an automatic algorithm is proposed to determine the number of antennas and dip angle setting.The algorithm can not only correct the existing scheme,but also provide a basis for designers in the subsequent construction.
