Résumé: Convergence, interoperability, and mobility are the major advances and factors of differentiation in 3G networks, while the inherent IP support will boost new personalized multimedia services. However, the deployment of a global all-IP wireless/mobile network is not a straightforward decision. A phased approach, focusing on "hot-spot" locations with complementary wireless technologies, seams to be one of the most realistic alternatives. This letter discusses a new architecture called Unified Wireless Access that focuses on public "hot-spots." The major algorithms of UniWA are analyzed and evaluated, while the gain is presented and illustrated in selected graphs.
