The business model impact of flexible spectrum management and cognitive networks

Purpose - This paper aims to give a short overview of European Union policy trends towards more flexible forms of spectrum management. Design/methodology/approach - The paper presents a business modelling analysis, scenario construction, policy analysis and roadmapping. It argues that both flexible spectrum management and the concept of...

Migration of existing access networks towards multi-radio access

Integration of heterogeneous access technologies to provide multi-radio access allows for dynamic access selection. The "always best connected" paradigm can increase system capacity and end user throughput, as well as, reduce the network deployment costs for multi-radio wireless networks. In this paper we present the functional entities Generic...

The 4GPLUS project, overview and main results

A 4G-environment is based on the integration of 3G mobile and other wired and wireless technologies into an all-IP network environment. Central to such an environment is a 4G-service platform, which offers services such as AAA, mobility management and session control, and also mediates between the users and providers of these services. Each...

Analysis of flow transfer times in IEEE 802.11 wireless LANs

In this paper we present an integrated packet/flow level modelling approach for analysing flow throughputs and transfer times in IEEE 802.11 WLANS. It captures the statistical characteristics of the transmission of individual packets at the MAC layer and takes into account the system dynamics due to the initiation and completion of data flow...
