Definition of cognitive radio
- This strategy would allow a portable radio receiver to monitor a wide swath of the spectrum at all times without swiftly burning through its batteries. That will be important in the much-anticipated world of cognitive radio, in which our handsets become agile enough to exploit frequencies that are fair game only when a higher-priority user hasn't claimed them.

- For example, if the government has reserved some spectrum for use at an Air Force bombing range, but no bombing is happening on a particular day, cognitive radio could allow a phone to sense the open channel and switch to it.
