How do 802.11k and 802.11r contribute to reduced latency in Wi-Fi Agile Multiband enabled networks?

Both technologies reduce the time it takes a client to roam between APs in the same network.

  • 802.11k reduces roaming time by allowing the client to rapidly determine which AP it should roam to next so when the client is ready to roam, it has a better idea of where to roam.
  • 802.11r also enables faster roaming by allowing encryption keys to be stored on network APs so the client does not need to perform the complete authentication process every time it roams to a new AP within the network.
