Abstract:
Opportunistic access has been considered by regu-
lators for a number of different spectrum bands. In this paper,
we discuss and qualitatively evaluate techniques used in the
discovery of spectrum opportunities, also called white spaces,
in the radar, TV, and cellular bands. These techniques include
spectrum sensing, cooperative spectrum sensing, geolocation
databases, and the use of beacons. We make the case that each of
the three bands considered calls for a different set of spectrum
access techniques. While TV bands are well matched to the
adoption of geolocation databases, a database-assisted spectrum
sensing mechanism may represent the most efficient solution
to exploit the spectrum holes in radar bands. We drew this
conclusion based on a multitude of factors, such as the radar
antennas’ constant motion, and the absence of a hidden node
problems in these bands. The unpredictability of cellular systems,
on the other hand, calls for a more coordinated spectrum access
approach, namely beacon signaling, that could be implemented
using the already established cellular infrastructure and spare
bits of its logical channels.
