The wireless network card continuously samples surrounding frequencies. When the signal quality hits a specific threshold, the device initiates a handover sequence to a target AP without dropping active network sessions. Adjusting the aggressiveness configuration directly modifies the mathematical signal threshold required to trigger this background scanning mechanism.

Wireless client devices—such as laptops, smartphones, and tablets—make the ultimate decision to switch access points based on the Received Signal Strength Indicator (RSSI). When a user moves away from an active AP, the RSSI drops.
