WISE2 project (2013-2014) focuses on incumbent protection methods for shared spectrum. For TV white spaces digital video broadcasting and wireless microphones are considered. ASA/LSA spectrum sharing is investigated in 2,3 – 2,4 GHz frequency band to coexist with PMSE equipment such as wireless cameras. Additionally, we pilot technologies and services utilizing shared spectrum.

The objective of the WISE project (2011-2012) was to construct a testbed for studying the use of cognitive radios utilizing white spaces of the UHF broadcasting band (470-790 MHz), which are the first previously reserved frequency bands to become available for cognitive radio allocation. In the project, an open cognitive radio geolocation database testbed was developed, allowing practical studies of the usability, algorithms, and interfaces of cognitive radio systems operating in television broadcast bands.

Now, we focus on the utilization of the testbed with several service pilots utilizing TV white spaces: rural broadband, wireless surveillance systems, smart grid, intelligent transport systems, and machine-to-machine communications. Additionally, our shared spectrum analyses have been extended to cover ASA/LSA spectrum sharing model.

WISE2 project will provide technical enablers for spectrum sharing and demonstrate service showcases to promote business opportunities for diverse field of systems utilizing wireless communications.
