  • Patent number: 12373318
    Abstract: A disclosed method may include (i) initiating a cellular field testing tool that tests a condition of cellular network connectivity of a device under test, (ii) checking, prior to starting a specific test of the cellular field testing tool, whether each precondition in a set of preconditions is satisfied, and (iii) preventing the cellular field testing tool from starting the specific test until each precondition in the set of preconditions is satisfied. Related systems and computer-readable mediums are further disclosed.

  • Publication number: 20250220466
    Abstract: A disclosed method may include (i) initiating a cellular field testing tool that tests, during a test case, a condition of cellular network connectivity to both a device under test and a reference device, (ii) comparing, by the cellular field testing tool, how well the device under test performs with how well the reference device performs, (iii) determining, by the cellular field testing tool, a theoretical throughput level corresponding to an expected value of a network connection between the device under test or the reference device and a cellular base station, and (iv) displaying, by the cellular field testing tool, a color-coded graphical representation of a category indicating how well the device under test or the reference device performs in comparison to the theoretical throughput level such that the displaying enables a user to detect whether a problem exists with the network connection to the device under test or the reference device.

  • Publication number: 20250212067
    Abstract: A disclosed method may include (i) initiating a cellular field testing tool that tests a condition of cellular network connectivity of a device under test, (ii) detecting first results of performing a first series of communication channel handover procedures at a device under test, (iii) detecting second results of performing a second series of communication channel handover procedures at a reference device, (iv) outputting, by the cellular field testing tool, an indication of whether the device under test passed or failed the first series of communication channel handover procedures at least in part by comparing the first results of the first series of communication channel handover procedures at the device under test with the second results of the second series of communication channel handover procedures at the reference device. Related systems and computer-readable mediums are further disclosed.

  • Publication number: 20250192897
    Abstract: A disclosed method may include (i) initiating a cellular field testing tool that tests a condition of cellular network connectivity of a device under test, (ii) detecting, by the cellular field testing tool, a first data structure specifying a first cellular carrier aggregation configuration at the device under test, (iii) detecting, by the cellular field testing tool, a second data structure specifying a second cellular carrier aggregation configuration at a reference device, and (iv) outputting, by the cellular field testing tool, an indication of whether the first cellular carrier aggregation configuration and the second cellular carrier aggregation configuration satisfy a consistency policy applied by the cellular field testing tool to ensure that a performance test is performed under conditions in which the first cellular carrier aggregation configuration and the second cellular carrier aggregation configuration are sufficiently similar to ensure reliable output of the performance test according to the c

  • Publication number: 20250142383
    Abstract: A disclosed method may include (i) initiating a cellular field testing tool that tests a condition of cellular network connectivity of a device under test, (ii) collecting logs of raw data from the cellular field testing tool based on the cellular field testing tool testing the condition of cellular network connectivity of the device under test, and (iii) applying autonomously, by the cellular field testing tool, an intelligent testing policy for a specific network condition test to the logs of raw data to output a binary decision of whether the specific network condition test passed or failed. Related systems and computer-readable mediums are further disclosed.
