Before revision:  Moreover, we identify the long-range dependence in 802.11 and 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  L\'evy \alpha-stable distribution with \alpha \in (1,2) entailing infinite variances, leaning tendency, and directional unfairness .
After revision:  Moreover, we identify the long-range dependence in 802.11 through both of mathematical and empirical wavelet-based analyses and answer a riddle: the absence of long range dependence in aggregate total load. We also 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  L\'evy \alpha-stable distribution with \alpha \in (1,2) entailing infinite variances, leaning tendency, and directional unfairness .
