  • System and method for performing over-the-air testing of device under test
    Patent number: 10575199
    Abstract: A method is provided for performing over-the-air (OTA) testing of a device under test (DUT). The method includes establishing an OTA connection with the DUT, while the DUT is in signaling mode, the OTA connection including advertising channels and data channels; sending universally unique identifier (UUID) requests at different transmit powers to the DUT over the data channels of the OTA connection; receiving UUID responses from the DUT over the data channels of the OTA connection in response to at least some of the UIDD requests; and determining a packet error rate (PER) for the received UUID responses from the DUT based on a ratio of a number of received responses and a number of sent connect requests. The determined PER indicates sensitivity of a receiver in the DUT.
