Apple documents 802.11k, 802.11r and 802.11v support on iPhone and iPad, a -70 dBm roam trigger with a new access point needing 8 dB more signal while the device sends data or 12 dB more when idle, and static PMKID caching on every device.

Values

Parameter	Value	Condition
Fast transition (802.11r)	Supported (PSK and 802.1X)¹	iPhone 5s or later and the listed iPads. Apple says FT works with PSK or 802.1X depending on the Wi-Fi hardware vendor, and documents one network vendor's adaptive 802.11r mode from iOS 10 and iPadOS 13.1
Fast transition with WPA3 R3	H2E Fast Transition (WPA3 R3, iOS 16)²	Listed among WPA3 R3 features from iOS 16 and iPadOS 16 on iPhone 11 or later and iPads from late 2020 or later
FT over the air or over the DS	Not published by the vendor¹	Checked the roaming support page
PMKID caching	Static PMKID caching supported¹	Every listed device, with or without 802.11r. Apple also describes sticky key caching (SKC) for returning to an AP already visited, and says SKC is not compatible with OKC
Opportunistic key caching	Not published by the vendor¹	Apple names OKC only to say sticky key caching is not compatible with it; it does not say whether devices use OKC
Neighbor reports (802.11k)	Supported¹	iPhone 5s or later and the listed iPads; the device uses the first six neighbor report entries to set the order of channels it scans
BSS transition management (802.11v)	Supported¹	The device reviews the BSS transition data the network supplies to choose which AP to roam to
Roam trigger and candidate margin	Below -70 dBm; new AP 8 dB (data) or 12 dB (idle) stronger¹	iPhone 5s or later, the listed iPads and Apple Vision Pro. Apple's example is a call at -75 dBm, where the phone looks for an AP of at least -67 dBm. Antennas differ by model, so Apple says to measure cell overlap with the target device
Roam scan with neighbor reports	With 11k, scans the reported channels first¹	Uses the first six neighbor report entries, scanning only for APs in the current ESSID
Roam scan without neighbor reports	Without 11k, all 2.4/5 GHz channels and 6 GHz PSCs¹	PSCs are the 6 GHz preferred scanning channels. Apple says scanning every channel can add several seconds to the roam. 6 GHz networks are also found out of band, through the Reduced Neighbor Report in 2.4 and 5 GHz beacons
Bands and standards	2.4, 5 and 6 GHz; up to Wi-Fi 7, by model³	Wi-Fi 7 with MLO on iPhone 16, 16 Plus, 16 Pro, 16 Pro Max and later listed models; 6 GHz on iPhone 15 Pro and 15 Pro Max; 2.4 and 5 GHz only on iPhone 11 to 14, 16e and 17e. 6 GHz only where the regulatory domain allows it
Wi-Fi security	WPA2/WPA3 Personal and Enterprise, 192-bit²	WPA3 on iPhone 7 or later and iPad 5th generation or later; WPA3 Enterprise 192-bit on iPhone 11 or later and iPad 7th generation or later; WPA, WEP and TKIP kept for compatibility only
Candidate scoring	Scores signal, channel use and client count¹	Prefers newer Wi-Fi generations (Wi-Fi 7 over 6 over 5) and wider channels when it chooses among candidates
Band preference when joining	Prefers 5 or 6 GHz above -65 dBm⁴	Auto-join on iOS and iPadOS, for networks broadcast on 2.4 GHz and on 5 or 6 GHz
