Abstract
A method including operating at least one hardware processor for: receiving, using a first transceiver, a radio-frequency (RF) transmission from an RF device; extracting one or more signal samples from said RF transmission, wherein the signal samples are associated with at least one of: (i) a rise transient associated with a data packet of said RF transmission, (ii) a fall transient associated with the data packet, and (iii) a region of the RF transmission occurring between the rise transient and the fall transient; and determining the presence of a second transceiver in the path of the RF transmission, based, at least in part, on processing the signal samples.
