Hi Kalle, In this context the term "link" does mean connection to AP. There are scenarios that require to lose connection faster once reduced link quality detected in order maintain better user experience (from both sides - AP and STA). Example case is FST (Fast Session Transfer), where we have a fast 11ad connection but close-range and a backup 11ac connection which is "always on". in such cases if we detect poor link quality in the active band we prefer to disconnect and switch to the backup connection with the good link quality. This will be reached by setting "aggressive" profile that will cause more rapid disconnect in such cases. Alexei Lazar Qualcomm Israel, on behalf of Qualcomm Innovation Center, Inc.
