In Wi-Fi networks with many end devices, they all compete for the available transmission time. Airtime Fairness ensures that fast devices then have the right of way and are not thwarted by slow Wi-Fi devices.
Usually, a home network supplies numerous end devices with Internet, some of which are active at the same time. These diverse clients compete for the available transmission time. This is because an access point transmits to the active clients in turn, regardless of the transmission time required in each case. Since old clients – or those with a bad connection – can take longer, all other clients have to wait their turn. This is where Airtime Fairness comes into play.
Airtime Fairness ensures efficient use of the available transmission time. This function detects when a client can complete the data transmission in a short time and thus gives fast devices the right of way.
Slower, usually older devices that take a long time to download, for example, thus no longer slow down the entire Wi-Fi home network. Overall efficiency increases and contemporary, fast end devices can make use of their full speed advantages.
