Cognitive radio technology is a smarter, faster, and more efficient
way to transmit information to and from fixed, mobile, other
wireless communication devices. Cognitive radio builds upon
software-defined radio technology. A cognitive radio system is
'aware' of its operating environment and automatically adjusts
itself to maintain desired communications-it's like having a
trained operator 'inside' the radio making constant adjustments for
maximum performance. Operating frequency, power output, antenna
orientation/beamwidth, modulation, and transmitter bandwidth are
just a few of the operating parameters that can automatically be
adjusted "on the fly” in a cognitive radio system.

Fette has constructed a cutting-edge volume that hits all of the
important issues including research, management, and support.
Cognitive techniques will be discussed such as position and network
awareness, infrastructure and physical and link layer concerns.
Though still a nascent technology, cognitive radio is being pushed
by the US military and for mission-critical civilian communications
(such as emergency and public safety services).
