  • Publication number: 20250233813
    Abstract: A wireless communication method and system are disclosed. After a station is wireless connected to an agent, the agent monitors airtime of each link of the station to report a first link status to a controller. The controller collects the first link status and detects scenarios based on the first link status. The controller determines to select among an initial second link and a candidate second link status as a second link status based on whether a throughput of the candidate second link status is higher than a throughput of first link status. The controller informs the second link status to the agent, and the controller wireless communicates with the agent over bands corresponding to the second link status.
