We denote it FWBM for Fenton-Wilkinson based method. The second one is based on the central limit theorem for causal functions. It allows to approximate a sum of positive random variables by a Gamma distribution. We denote it CLCFM for central limit theorem for causal functions method. Each method allows to establish a simple and easily computable outage probability formula, which jointly takes into account path-loss, shadowing and fast fading. We compute the outage probability, for mobile stations located at any distance from their serving BS, by using a °uid model network that considers the cellular network as a continuum of BS. We validate our approach by comparing all results to extensive Monte Carlo simulations performed in a traditional hexagonal network and we provide the limits of the two methods in terms of system parameters. The proposed framework is a powerful tool to study performances of cellular networks, e.g., OFDMA systems (WiMAX, LTE). %G English %2 https://hal-imt.archives-ouvertes.fr/hal-00666681/document %2 https://hal-imt.archives-ouvertes.fr/hal-00666681/file/eurasip11ffading.pdf %L hal-00666681 %U https://hal-imt.archives-ouvertes.fr/hal-00666681 %~ INSTITUT-TELECOM %~ CNRS %~ ENST %~ TELECOM-PARISTECH %~ PARISTECH %~ LTCI %~ INFRES %~ RMS %~ INSTITUTS-TELECOM
