Cognitive Radio and “Hype”
Cognitive Radio Systems, rather than CR

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)
