Abstract: Techniques are provided for utilizing wireless devices for contact tracing, and more specifically for detecting a barrier between devices to enhance contact tracing applications. An example method for detecting a barrier between a first device and a second device includes determining, by the first device, a first range measurement with respect to the second device using a first positioning technique determining, by the first device, a second range measurement with respect to the second device using a second positioning technique that is different from the first positioning technique, and detecting the barrier between the first device and the second device based on the first range measurement and the second range measurement.
