随着现代社会无线蜂窝网络的无缝覆盖，考虑无线蜂窝覆盖的形状很有趣。形状是正六边形、不规则多边形还是其他复杂的几何形状？基于分形理论，利用上海地区实测的无线蜂窝数据，确定了无线蜂窝覆盖边界的统计特征。测量结果表明，无线蜂窝覆盖边界呈现出极不规则的几何形状，也称为统计分形形状。此外，无线蜂窝覆盖边界的统计分形特征已被验证的值的Hurst参数估计的角度尺度。无线蜂窝网络覆盖边界的统计分形特性可用于评估和设计无线蜂窝网络中移动的用户终端的切换方案。
With the seamless coverage of wireless cellular networks in modern society, it is interesting to consider the shape of wireless cellular coverage. Is the shape a regular hexagon, an irregular polygon, or another complex geometrical shape? Based on fractal theory, the statistical characteristic of the wireless cellular coverage boundary is determined by the measured wireless cellular data collected from Shanghai, China. The measured results indicate that the wireless cellular coverage boundary presents an extremely irregular geometrical shape, which is also called a statistical fractal shape. Moreover, the statistical fractal characteristics of the wireless cellular coverage boundary have been validated by values of the Hurst parameter estimated in angular scales. The statistical fractal characteristics of the wireless cellular coverage boundary can be used to evaluate and design the handoff scheme of mobile user terminals in wireless cellular networks.
