2 Background Long history of Cognitive radio and WS research Standardization activities in IEEE , af, ETSI RRS... From sensing only to database based models Focus on ensuring co-existence of different systems Global harmonized model for White Space operation TVWS may lead to change in the way the spectrum is allocated in the future 2 Nokia 2011 TVWS_trial.pptx v NKi Document ID

3 TVWS trial network Build trial network with real users, real services and real problems Playground for developing and improving technology solutions and innovating use cases for Finnish academia and industry Use the learnings to influence regulation rulings and standardization regarding both the TVWS and WS generally Simple, not yet fully optimized, technology platform supporting variety of mobile use cases 3 Nokia 2011 TVWS_trial.pptx v NKi Document ID

4 USB I/F TVWS network - architecture Regional Database A Regional Database B Ensure interoperability between different secondary users as well as with the primary user Primary users Secondary users USB dongle operating at TVWS frequencies that can be attached to multiple host devices.
