The roaming problem: seamless WiFi across APs

When you walk across an office, your device must smoothly switch between access points — roaming. With basic WPA2, roaming requires a full 4-way handshake per AP: 100-300ms of interruption. For a VoIP call, this sounds like a momentary silence. For video conferencing, it's a noticeable freeze.

802.11k helps find the next AP faster. 802.11v lets the network suggest when to roam. 802.11r completes the handoff in under 50ms.
