摘要
基于目前基站空间分布无固定规律性这一现状,为了探究基站空间分布特性,提出一套测量方案,结合F函数(empty space function)及包络函数理论分别对英国3种不同区域的实际基站分布数据进行了分析并对比。当F函数自变量r足够小或足够大时,3个区域基站分布均接近较理想的泊松分布状态,当r分别达到一定数值时基站分布呈现聚集性的特点。同时,不同区域基站的聚集程度由其特有的地理环境和人口分布决定,基站分布密度与人口密度成正相关。两市区基站技术选型配比近似,郊区基站中涉及第3代移动通信技术的基站占主导。
Based on the present situation that there＇s no fixed regularity of base stations＇ spatial distribution,in order to probe into base stations＇ spatial distribution characteristics,real base stations＇ distribution data of three different areas are collected,analyzed and compared respectively by means of F function（ empty space function） and envelope function. When the variable r of F function is small or big enough,the three regions＇ F function curves are all close to the ideal Poisson distribution curve,while the r reaches a certain value,the base stations＇ distribution presents the characteristic of clustering. At the same time,the aggregation degrees of base stations are determined by the unique geographical environment and the population distribution of different areas. What＇s more,the base stations＇ density distribution and the population density are positively related. The base stations＇ technological types in two cities are similar. While,in the suburban,base stations involved in the third generation communication technology are dominant.
