Abstract: This disclosure provides methods, devices, and systems for performing passive scanning operations on one or more wireless channels. In some implementations, a wireless communication device configures an off-channel scan time and a passive scanning period for passive scanning operations based on latency requirements of a low-latency application, and selects a home channel dwell time for the passive scanning operations. The wireless communication device may perform the passive scanning operation by alternating between listening for beacon frames on one or more second wireless channels for the configured off-channel scan time and dwelling on a home channel for the selected home channel dwell time during a first portion of the configured scanning period. The wireless communication device also may listen for beacon frames on the one or more second wireless channels during a second portion of the configured scanning period that is defined by the selected home channel dwell time.
