Easy Wireless goals
• Allow service continuity with managed QoS and adaptive service provisioning for mobile users in heterogeneous networking environment
• Strengthen the European expertise and competence in this area of communications
• Pave the way for the interoperability of different networks supporting the transitioning to latest communication technologies
VTT TECHNICAL RESEARCH CENTRE OF FINLAND
Technical background
• Different network technologies are converging in Europe and globally
• New technologies (hotspots, EDGE, 3G) allow higher data rates enabling new services (VoD, peer-to-peer video, videoconferencing, etc) in wireless networks
• Multimedia services require guaranteed QoS with high bandwidth and low latency
• User acceptance for new services depends strongly on the user experienced quality of the service.
• Future services need to be available wirelessly
• Services need to be trustworthy and easy to use
• Service provisioning must meet the user expected quality
VTT TECHNICAL RESEARCH CENTRE OF FINLAND
Major results of Easy Wireless
• Open architecture allowing to realise service continuity with managed QoS in heterogeneous network environments
• Demonstrators showing the feasibility and performance of the proposed architecture and mechanisms
• Contributions to networking and communications standards
• Scientific publications
• Increase interoperability between different technologies and improve QoS capabilities in wireless protocols

Work of the Finnish sub-consortium
VTT • Develop architecture to measure, test and control the end-to-end
QoS over heterogeneous networks (including cellular access networks, IP core networks, and wireless hotspots)
• Qos measurements• Co-operation of QoS mechanisms in different networks• Congestion control, flow control and scheduling mechanisms• QoS-aware transport protocols for multimedia communications
• Set up demonstration platform with selected network technologies in order to show the performance and feasibility of the architecture
• Vertical handover between 3G and WLAN while maintaining QoS• Real-tíme QoS measurement tool• QoS measurements in cooperation with Nethawk
Nethawk• QoS measurements and analysing methods

Participating in the EW project
• Funding already approved in Finland for VTT and Nethawk
• Tekes –funding is 35-50% of the company’s total project costs
• Next funding period: 1.7.2005 – 31.12.2006
• Each partner is responsible for it’s own costs
• Possibility to get extra funding for R&D work, when the topics are in line with the project
• International contacts
• IPR can be protected
• Standardization, the aim is to introduce project results to standardization bodies
• Gather latest knowledge in end-to-end QoS research
• New partners are welcome to join the project any time
