Fig. 9From: The virtual small cells based on UE positioning: a network densification solutionStatistics on hotspots radius. This figure represents a CDF of the hotspots radius where 25% of the radius are below 32.7 m, half of the radius are below 39.4 m and 75% of the radius are below 50 m. A nearly Gaussian distribution for the cluster radius is observed which means that the closest value from the mean are more able to appear than the othersBack to article page
