Network Roaming Configuration

Not all clients and operating systems support 802.11r, 802.11k and 802.11v.

Apple iOS

Microsoft Windows

Windows 10 supports these 802.11 amendments but only using certain drivers.

When a device roams from one AP to another on the same network, 802.11r uses a feature called Fast Basic Service Set Transition (FT) to authenticate more quickly.

FT works with both preshared key (PSK) and 802.1X authentication methods.

Adaptive 802.11r offers FT without the need to enable 802.11r on the configured Cisco wireless network.

The 802.11k standard helps clients more quickly search for nearby APs that are available as roaming targets by creating an optimized list of channels. When the signal strength of the current AP weakens, your device will scan for target APs from this list. 802.11v enables the basic service set (BSS) transition-management functionality for compliant devices.

BSS transition management allows the network’s control layer to influence client roaming behavior by providing it the load information of nearby access points. Some adapter providers, such as iOS, take this information into account when deciding among the possible roam targets.

When you combine 802.11k and 802.11v’s ability to speed up the search for the best target AP with FT’s faster AP association, apps can perform faster and you get a better Wi-Fi experience.
