Disclosed is a method of operating a test system for over-the-air, OTA, testing of at least two mobile devices under test, DUTs. The at least two mobile DUTs have respective mobile subscriber identities, IMSIs. The method comprises simulating, by a mobile radio cell simulator connectable to the test system, a first mobile radio cell being open for attachment by all of said mobile DUTs, and attaching all of said mobile DUTs to the first mobile radio cell. The method further comprises simulating, by a mobile radio tester connectable to the test system, a second mobile radio cell being barred for attachment by said mobile DUTs. The method further comprises prompting, by the mobile radio cell simulator, one particular DUT of said mobile DUTs to perform a handover to the second mobile radio cell. The method further comprises subjecting, by the mobile radio tester, the particular DUT to an OTA test procedure within the second mobile radio cell. The method further comprises prompting, by the mobile radio tester, the particular DUT to leave the second mobile radio cell. The method further comprises indicating a status of the particular DUT subjected to the OTA test procedure.

A method for detecting coverage problems is provided. The method includes receiving, at data processing hardware, from at least one user equipment (UE), observations. Each observation includes a signal measurement of a signal emitted from a base station and a corresponding location of the signal measurement. The method also includes generating, by the data processing hardware, a coverage map for the base station based on the received observations, the coverage map indicating a signal characteristic of the emitted signal about the base station. The method further includes determining, by the data processing hardware, an estimated characteristic of the base station by feeding the coverage map into a neural network configured to output the estimated characteristic of the base station.

Methods, systems, and apparatuses are described for testing communication with a device. A multimedia receiver may be communicatively coupled to a media device, such as a source media device. The multimedia receiver may transmit a test command to control the source media device using a communication protocol. A video frame output by the source media device may be obtained. Based at least on the video frame, it may be determined whether the source media device received the test command. In response to a determination that the source media device received the test command, an indication may be stored that the source media device may be controlled using the communication protocol.
