On the Sampling Frequency of Human Mobility

Abstract : In this paper, we aim at answering the question " at what frequency should one sample individual human movements so that they can be reconstructed from the collected samples with minimum loss of information? ". Our quest for a response unveils (i) seemingly universal spectral properties of human mobility, and (ii) a linear scaling law of the localization error with respect to the sampling interval. We conduct analyses using fine-grained GPS trajectories of 119 users worldwide. Our findings have potential applications in ubiquitous computing and mobile service design, in terms of energy efficiency, location-based service operations, active probing of subscribers' positions in mobile networks and trajectory data compression.
