Some U-Washington researchers are working on a potentially very
interesting project of using sensors and statistical analysis to
identify where cell site simulators are being used, which could scale to
city or larger size, providing a snapshot as well as ongoing dataset to
ascertain patterns. One would need spatial and temporal density to
maximize probability of capture given the ephemeral nature of deployed
cell simulators.
