             CR Making Sense
                 on the slope of enlightenment

                     • CRs are only as good as the information they use for
                             their decision making
                         - definition of information scope
                         - loads of sensing technologies but no quality indicators
                         - interoperability between (spectrum sensors)
                     • Making Sense:
                         - Secondary spectrum usage will come (already reality – 5GHz band)
                         - Regulation will allow more dynamic allocation regimes
                         - Reconfigurable radios will operate in different frequency
                           ranges/bands and would have to apply different sensing
                           architectures (band and space dependent sensing)

                     • Making Sense:
                         - Use case impact on sensing requirements

                     • Interest group within SCC41 addresses issue of sensing for
                       Distributed Spectrum Access and Advanced (Cognitive) Radio
