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)
