cognitive radio
n.— «That action brought to the fore founding research by Joseph Mitola, who coined the term cognitive radio (CR).…Derived from a need for more-efficient spectrum use, a CR fundamentally senses whether a band is being used and jumps in when the band is unoccupied. It jumps to another band when the primary user recommences transmissions.» —“CR hailed as ‘next big thing’ in wireless” by Patrick Mannion Electronic Engineering Times Nov. 16, 2004.
