  • Publication number: 20220377594
    Abstract: The present invention provides a method and system for managing the connections of multiple stations in a Wi-Fi mesh network, using station steering to optimize the overall throughput of the network. The stations are proactively steered depending on the link quality, the network topology and wireless medium occupation, as well as the different equipment capabilities, to ultimately provide the best available throughput. This invention also aims to detect crowded Access Points or frequency bands, and steer stations accordingly towards an efficient load control and traffic management between nodes/Access Points and improved quality of experience.
