This 10-part series discusses the notion of “cognitive” radio, the combination of a radio transceiver with computerized intelligence to automate coordination of devices, networks and services for improved functionality, interoperation and spectrum utilization. The term originates from parallels with biological systems that interact with their environment using a regime of goals, sensory inputs and reactive behaviors to sustain themselves.
Cognitive radio, formerly the interest of a few, has now entered the “group think” environment, where “cognition” means many things to many people. Outgrowths of the concept have been advanced to address a variety of next-generation wireless origins and current forms. The author also attempts to forecast how FCC cognitive radio rulemaking may proceed in connection with its initiatives to achieve higher spectrum productivity.
