Abstract : In this report, we analyze a general model of large CDMA networks (Code Division Multiple Access) and we propose a new formalism to represent the workload in wireless networks. We focus on stability issues on the downlink when users in the network want to receive some data from the base stations. We derive the stability region of this data flows system when the network is either in full macrodiversity, in soft handover or in a cellular architecture. In particular, we prove, for the model we consider, that well-designed cellular networks achieve the same stability region as networks in macrodiversity. We extend also our results to networks when slow-fading and mobility are taken into account.
