Figure 1.

Data collapse of the simulation of the proposed model for cell phone communication with β = 0.5. In the figure we plot the probability $P_2^w\left(\tau \right)$ that in the model a pair of agents with strength w are interacting for a period τ. The collapses data of $P_2^w\left(\tau \right)$ is described by Weibull distribution as expected by the theoretical prediction indicated with a solid line.
