Abstract
A method comprising 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 said 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 said data packet, and (iii) a region of said RF transmission occurring between said rise transient and said fall transient; and determining the presence of a second transceiver in the path of said RF transmission, based, at least in part, on processing said signal samples.
Claims20
A system comprising:
- at least one hardware processor;
- and
- a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to:
- receive, using a first transceiver, a radio-frequency (RF) transmission from an RF device;
- extract one or more signal samples from said RF transmission, wherein said 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 said data packet, and
- (iii) a region of said RF transmission occurring between said rise transient and said fall transient;
- and
- determine the presence of a second transceiver in the path of said RF transmission, based, at least in part, on processing said signal samples.
