A method ensures Quality of Bandwidth (QoB) in a Wi-Fi connection between one or more wireless devices and an access point to an Internet. A hardware access point controller receives a plurality of requests for data transmission bandwidth between multiple wireless devices and an access point. The access point provides access to the Internet, the requests are for overlapping time periods. The hardware access point controller dynamically allocates subsets of bandwidth capacity provided by the access point to each of the wireless devices. A position detector detects a movement of a specific wireless device relative to the access point. The hardware access point controller identifies a change in data transmission bandwidth between the specific wireless device and the access point caused by the movement of the specific wireless device, and adjusts the subsets of bandwidth capacity by adjusting available frequencies for the specific wireless device.
