Samsung patents smoother Wi-Fi switching for multi-link devices

This filing describes a method for managing data packets that are waiting to be sent when a device moves from one Wi-Fi router to another. The current router tells the moving device which options are available for handling these waiting packets before the switch happens.

Why it mattersThis could make Wi-Fi connections feel less choppy when moving around a home or office, especially with newer multi-link Wi-Fi standards.

In the filing’s own words

Downlink (DL) data handling in seamless roaming in wireless local areas (WLANs). A method performed by a current access point (AP) multi-link device (MLD) includes identifying, from a plurality of options for handling of buffered frames at the current AP MLD for a non-AP MLD to roam from the current AP MLD to a target AP MLD, one or more of the options that are available for handling of the buffered frames and transmitting, to the non-AP MLD via a management frame, information indicating the one or more options that are available.

What exactly they claim (claim 1)
