توضیحات
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
Introduction
It is estimated that 90 percent of the world’s population over 6 years old will have a mobile phone
by 2020, that is, most of the population will be covered by wireless cellular networks [1]. The coverage shape of a wireless cell is formed by the wireless cellular coverage boundary, which is connected by all of the farthest locations around a base station (BS). The farthest locations are also called wireless cellular coverage boundary points, where the received wireless signal power is equal to the minimum power threshold Pmin configured by the cellular network. An important challenge for wireless cellular network providers is to ensure that mobile users are seamlessly covered by adjacent BSs, especially those located at the edge of wireless cells
