Abstract

This article outlines the economic feasibility of mobile operators that combine nationwide mobility with 3G networks and hot spot coverage withWLANS, WLANS are based onHIPERLAN/2 architecture and theUMTS network exploitswCDMA/FDD technology. The evaluated business scenarios are focused on two different deployment areas, in terms of demographic characteristics and mobile penetration: a large and a small European country. The business case spans 2002 to 2011 withUMTS’ roll-out year in 2002 andWLAN’s in 2004, covering indoor hot-spot areas (stations, airports, stadiums, etc.) where demand is high. The demand for thisUMTS-WLAN roaming case is evaluated based on observations from Europe’s current mobile market and its evolution. Usage scenarios of different service packages corresponding to both residential and business markets have been taken into account. Direct investments and operational costs as well as revenue streams from traffic have been calculated. The methodology and the tool developed inACTS-TERA [1] andIST-TONIC [2] projects have been utilized for this case study. Economic conclusions have been derived, presented and discussed using key profitability factors. Profitability for all scenarios and business profiles has been calculated, presented and discussed. It includes a sensitivity analysis in order to identify the major opportunities and threats, for specific service sets as well as critical parameters and uncertainties. A wide audience from mobile operators and service providers to retail companies interested in entering the 3G market, can exploit this information.

Résumé

Cet article souligne l’attrait pour les opérateurs mobiles que constitue la couverture des lieux publics à forte fréquentation par les réseauxRLAN en combinaison avec les réseaux 3G. les réseauxRLAN sont basés sur l’architectureHIPERLAN/2 et les réseauxUMTS sur la technologiewCDMA/FDD. Les scénarios économiques étudiés ont ciblé deux différents types de pays en terme de caractéristiques démographiques et de pénétration de la téléphonie mobile: un grand pays européen et un petit. Le plan d’affaire court sur 2002–2011 avec déploiementUMTS en 2002 et déploiementRLAN en 2004 pour la couverture des lieux publics à forte fréquentation tels que les gares, aéroports, stades, etc. où la demande est élevée. La demande dans ce modèle économique est estimée à partir de l’analyse du marché actuel de la téléphonie mobile en Europe et de son évolution. Les scénarios d’usage des différent services correspondant aux segments de marché entreprises et particuliers ont été pris en compte. Les investissements, le coût opérationnel ainsi que les revenus générés par le trafic ont été calculés. La méthodologie et l’outil développés dans les projets européensACTS-TERA etIST-TONIC ont été utilisés pour cette étude de cas. Les conclusions sont présentées avec une analyse de facteurs clés ainsi qu’une analyse de sensibilité incluant permettant d’identifier les principaux risques et opportunités.
