The Ambient Networks Project An integrated project co-sponsored by the European Commission under the Information Society Technology (IST) priority within the 6th Framework Programme (FP6) Aims at an innovative, industrially exploitable mobile network solution in particular for systems beyond 3G, which enables the composition of networks across business and technology boundaries in order to stimulate new business developments and growth in the wireless domain Brings together a strong industry led consortium of leading operators, vendors, SMEs, and research organisations, with the determination, skills and critical mass to create cross-industry consensus and to drive standardisation AdHoc'04 - NLC Concepts in WWI AN 4 May, 2004 4

AN Objectives to define an affordable and scalable mobile communication network, that opens up new ways to communicate, for billions of people and devices, to facilitate "ambient networking", allowing increased competition and cooperation, enabling efficient use of resources in an environment populated by a multitude of devices, technologies and business actors, to achieve a broad industry consensus on ambient networking, creating new business opportunities for mobile network service provisioning, to develop a solution that provides easy to use, rich and trustworthy multimedia communication services for all.

AN Multi-Radio Access architecture (MRA) For new, efficient and low-cost access networks, all relevant resources must be utilisable irrespective of administrative and technical boundaries No single operator can provide all the resources required for the best solution to any given user demand Legacy and new radio interfaces have to be efficiently integrated with self-deployed ad-hoc networks and multihop forwarding Current research fails to address the access problem in multiradio/multi-operator environments The AN MRA approach generalizes and extends current access network architectures Allows mixing of existing infrastructure with new components under varying business and spectrum management regimes Relies on Multi-Radio Resource Management (M-RRM) and Generic Link Layer (GLL) AdHoc'04 - NLC Concepts in WWI AN 4 May, 2004 35
