iOS, iPadOS, and macOS support these 802.11v functionalities on certain devices:
- Basic Service Set (BSS) transition management
- Disassociation Imminent
- Directed Multicast Service (DMS)
- BSS Max Idle Service
BSS transition management with Disassociation Imminent allows the network’s control layer to influence client roaming behavior by providing it the load information of nearby access points. The device takes this information into account when deciding among the possible roam targets.
DMS optimizes multicast traffic transmission on wireless networks. The device uses this information to enhance multicast communication and preserve device battery life.
The BSS Max Idle Service helps clients and access points efficiently decide how long to remain associated when no traffic is being transmitted. The device uses this information to preserve device battery life.
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 in iOS, iPadOS, and macOS.
