  • Patent number: 11184783
    Abstract: A communications system provides for accurate fingerprinting of devices across a communications channel. A transmitter device modifies a physical layer signal prior to transmission as a function of signal modification parameters. A receiver device classifies a received physical layer signal and to outputs a classification indicator and a score. The receiver further analyzes the classification indicator and the score to produce an updated set of signal modification parameters provides the parameters to the transmitter device. The transmitter device, in turn, updates its signal modification parameters accordingly, thereby generating subsequent communications that more clearly indicate a fingerprint of the transmitter device.

  • Patent number: 11178237
    Abstract: A method alters a computer resource while in a particular geolocation. One or more processors detect that a geolocation of a computer resource has changed from an initial geolocation to a new geolocation, where the computer resource is a virtual machine (VM). In response to detecting that the geolocation of the VM has changed from the initial geolocation to the new geolocation, the processor(s) reduce a functionality of the VM by reducing a quantity of processors and storage space available to the VM at the new geolocation as compared to the initial geolocation.

  • Patent number: 10862599
    Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.
