Flexible Radio: Intelligence as a third resource
• The design of works requires an increase for new capacity and higher
performance.
• The development of these capabilities is limited severely by the scarcity of two of the
principal resources in works, namely
Energy
Bandwidth.
• Recently, munity has turned to a third principal resource,
the deployment of intelligence at all layers of work
in order to exploit increases in processing power afforded by Moore’s Law type
improvements in microelectronics.

What is a Flexible Radio 50 years later?
Joseph Mitola III, ”Cognitive Radio: An Integrated Agent Architecture for Software Defined
Radio”, Royal Institute of Technology (KTH) Stockholm, Sweden, 8 May, 2000.
It is the ultimate point where devices are putationally intelligent about
radio resources to detect munication needs as a function of use context, and to
provide (without human intervention) radio resources and wireless services mo
