ABSTRACT
This paper outlines a dynamic spectrum allocation
framework that will mitigate the shortage of spectrum
by enabling more efficient sharing of this critical
resource. This approach involves coordinated
activities on three fronts: technology, policy, and
strategy. First, the approach capitalizes on emerging
radio technologies to increase the utilization of each
spectrum allocation. Applicable technologies include
per-packet adaptable radios, software-defined radios
(SDR), layered radio architectures, and spatial
diversity through advanced antennas. Second,
spectrum management policy will play an important
role in motivating radio developers to create and
field the requisite technologies. Such "technologyenabling"
policy may significantly differ from the
management policies in place today. Third, the
authors believe that the long-term solution to the
spectrum shortage can only be solved with a well
planned, coordinated, strategic vision. Such a vision
might best be captured in the form of a National
Strategic Spectrum Roadmap. It is the authors' belief
that together, technology, policy, and strategy can
address the pressing spectrum shortage and
"unblock" the spectrum.
