Cognitive Radios are aware of their surroundings and bandwidth availability, and are able to dynamically tune the spectrum usage based on location, nearby radios, time of day and other factors.

This provides for more efficient use of the spectrum as well as reducing power consumption.

Varied devices will be able to detect other radios around them and work together to optimize the use of spectrum, allocate resources, and more easily communicate with their peers.
