Hankkeen julkinen kuvaus
This project addressed cognitive radio networks as a platform to deliver ubiquitous wireless video. The outcomes of the project established the feasibility of using mobile devices as software-defined radio platforms in practice. The project also evaluated the performance of offloading traffic from the cellular network to unused frequencies in the TV bands, i.e., the so-called TV whitespaces. The key results from our studies demonstrated how using whitespaces improves the offloading capacity up to 60% when using opportunistic device-to-device communications and by about 50% when complementing the cellular network in urban scenarios. The project was carried out as a close collaboration between Finland and the United States.
