Spectrum Access

Abstract-- Dual site spectrum measurements have been
made in the public safety band in Howard County,
Maryland, USA. The public safety band is of interest
because of its obvious importance and the increasing need
to determine whether improved spectral utilization would
accommodate increased usage for public safety. Two
receiver suites were synchronized and used to measure
concurrent spectra at separations between a few meters up
to a few kilometers. These measurements prove useful in
examining issues of spectrum sensing for dynamic
spectrum access, including receiver sensitivity, primary
user signal detection, adjacent channel interference, and
policy performance with local and cooperative sensing. We
analyze the collected data to characterize the usage of this
public safety network and provide insights into how white
