  • Publication number: 20250071566
    Abstract: This application provides a coverage hole detection method and a related device in the field of communication technologies. If a coverage hole exists between two access point (APs), a terminal passes through the coverage hole when roaming between the two APs. Therefore, a roaming behavior of the terminal between the APs can reflect whether the coverage hole exists between the APs. An electronic device determines, based on a roaming behavior of a terminal between a first AP and a second AP, that a coverage hole exists between the first AP and the second AP. The roaming behavior of the terminal between the first AP and the second AP includes roaming behaviors of a plurality of terminals between the first AP and the second AP.
