The main objectives of WINNER are to:

• identify and analyse challenging user and usage scenarios to derive requirements for the WINNER radio interface
• define radio interface technologies needed for a ubiquitous radio system concept
• define radio network topologies and deployment concepts for the provision of a ubiquitous coverage area
• define radio level co-operation mechanisms between different Radio Access Networks (RANs)
• define a single ubiquitous radio access system concept, scalable and adaptable to different short range and wide area scenarios
• investigate the propagation conditions and to develop related radio channel models
• develop methods for efficient and flexible spectrum use and spectrum sharing
• contribute to the development of spectrum demand estimation methods in preparation for the World Radio Communication Conference (WRC) 2007
