Abstract
Techniques are provided for distinguishing between different signal sources where multiple sensor devices receive RF energy in an area such that some sensors may receive the signals from the same source device. One technique involves using a received signal strength (RSS)-based positioning technique to distinguish between sources. Another technique involves building a pseudo-MAC identifier from received transmissions of a device in order to distinguish transmissions from that device with respect to other devices. Still another technique involves synchronizing the sensor devices and examining the resulting waveform data at each of the sensor devices to determine if they match sufficiently to indicate that they are from the same source device.
