Spectrum occupancy measurements for different urban environments

In this paper we present the results of spectrum occupancy measurements conducted in different urban environments, in greater Melbourne area, Australia. We capture the dynamic nature of spectrum occupancy seen from a spatial perspective, by conducting spectrum monitoring measurements on board a mobile vehicle. With a wide spectrum window selected from 400 to 6000 MHz we aim to shed some light on the feasibility of utilizing smart spectrum access techniques facilitated by cognitive radios.
