Before revision:  Moreover, we {\it   show that the inter-transmission probability undergoes a dramatic change at \gamma_0=1/m^2 and falls into two qualitatively distinct categories: either approximately Gaussian or {\it L\'evy} \alpha-stable distribution with \alpha \in (1,2) entailing infinite variances, {\it leaning} tendency, and {\it directional} unfairness.
