Abstract: Providing resource control for public sharing of access points to private residential Wi-Fi networks. A control component takes periodic free airtime (FAT) measurements to provide adaptive access control by public devices to private networks. Normal and generous threshold levels are provided to differentiate various actions allowing or denying public device access to prevent public usage from impacting the private user experience. The system constantly measures free airtime and only grants public device access to their Wi-Fi as a public hotspot if sufficient free airtime is available to seamlessly preserve the private user experience. Public usage is maximized by providing real-time determination of free airtime to allow spare capacity to be used by as many public users as feasible.
