Cognitive radio at the other end of the spectrum [Kerry Hartnett ]

Cognitive Radio at the other end of the spectrum Kerry Hartnett Intel Labs

Explanations
N4C – FP7 funded research project
DTN – Delay/disruptive Tolerant Networks
Where to use it?
where links are unstable or do not exist as we currently understand them
Cognitive angle
Use what bandwidth is available on what ever radio is available, e.g wifi, wimax,
DTN sits under this and ensures data transfer

Cognitive Opportunities
Atom based system
Cognitive Systems will need to be light weight, low power, instant on, flexible comms,
Atom based systems can supply this capability
WiMax
A wireless broad band solution that will provide bandwidth required over short time period over long distance, on/off solution
Cognitive Radio over DTN
