Wi-Fi roaming fundamentals

Roaming in Wi-Fi networks occurs when a client device moves between access points (APs) using the same SSID. The decision to roam is made primarily by the client, based on RF conditions such as SNR, RSSI and channel utilization.

Without optimization, roaming may introduce latency, packet loss and short connection drops. This is critical for real-time applications such as VoIP, video or industrial terminals.
