Spectrum Access and the Promise of Cognitive Radio Technology
Cognitive radio technology, inclusive of software and software definable radio technology, are key components for realizing this vision
Goal is to Promote Efficient Use of the Spectrum!
Webster’s New Collegiate Dictionary
Improve accessthrough time, frequency,power, bandwidthand space
Adjust regulationsas technology develops
Permit otherusers or uses --
Some spectrum is intensively used
Other spectrum has highly variable use in when viewed in terms of time and geography
Below the Acceptable
Use of public safety spectrum is highly variable
Quantify acceptable levels of interference
Can Cognitive Radios capture the Interference Temperature?
How should Cognitive Radios exploit this information ?
Prevent Aggregation Above Interference Temperature Limit
New Opportunities for Spectrum Access
Power at Receiver
Current FCC Power Limits
Distance from licensed transmitting antenna
These Key Questions will hopefully be addressed during this workshop
