What it shows

  • 802.11k shares neighbor AP reports, eliminating full-band channel scans.
  • 802.11v lets the network actively steer clients to optimal frequency bands.
  • 802.11r caches master keys to slash handoff delays from 1200ms to <50ms.

The takeaway

802.11r/k/v work together to ensure seamless sub-50ms handoffs without dropping active VoIP calls.
