Cognitive radio terminals sense the spectrum to detect temporarily unoccupied spectrum gaps and transmit. The behavior of a network of cognitive radio terminals therefore depends on the spectrum occupancy perceived by each terminal at its local environment. In this context, this work explores (via empirical measurements) the spectrum occupancy that would be perceived by a cognitive radio terminal over a rich diversity of practical scenarios, including indoor environments as well as outdoor locations in high points and at the ground level (in open areas and between buildings). The impact of considering various locations on the spectral activity perceived by a cognitive radio terminal is determined, analyzed and quantified. The variety of considered scenarios provides a broader view and understanding of dynamic spectrum occupancy under different realistic scenarios of practical interest.
