Abstract: Systems and methods can support identifying threats in short-range wireless communications, such as Bluetooth, using one or more radio frequency sensors to receive signals transmitted between a master device and a slave device. Packets can be identified within the received signals and designated as originating from the master device or from the slave device. The wireless interface can be identified as synchronous or asynchronous. Lengths of data may be identified for data payloads within the packets. Total aggregate data lengths may be calculated for both the master and the slave transmissions. Time slot utilization statistics can be computed. A connection type category may be determined using these wireless connection features. The connection type may be for peripherals, streaming audio, two-way headsets, object exchange, data tethering, and so forth.

Abstract: Systems and methods can support identifying multiple radio transmitters as being integrated within a single communications device. Radio frequency signals may be collected using one or more sensors incorporating radio receivers. A first radio frequency signature and a second radio frequency signature may be identified within one or more of the radio frequency signals as originating respectively from a first radio transmitter and a second radio transmitter. Characteristics of the first and second radio frequency signatures may be analyzed to evaluate a relationship between the first and second radio frequency signatures. It may be determined whether or not the first and second radio transmitters are integrated within a common wireless electronic device based upon the evaluated relationship between the first radio frequency signature and the second radio frequency signature. Characteristics and behaviors associated with the wireless electronic device may be determined therefrom.
