Feb 27, 2014 · What is Fast Transition. Fast Transition is Cisco’s lingo for IEEE 802.11r. 802.11r is an amendment to IEEE 802.11 and was ratified in 2008. The standard defines fast roaming between APs. How Does it Work. The concept of fast roaming is that the device creates a handshake with another AP even before the client roams to the new AP..
2018. 10. 21. · WPA3 fixes things by using “individualized data encryption”. When you connect to an open Wi-Fi network, the traffic between your device and the Wi-Fi access point will be encrypted, even though you didn’t enter a passphrase at the time of connection. This will make public, open Wi-Fi networks much more private.
Roaming on WPA2 and WPA3 I have noticed that roaming doesn't work as well wen WPA3 is enabled in labs. When in a facetime call or wifi call the sound clips out for about a second when the phone changes station. With WPA3 disabled I don't notice anything then the device roams whilst in a call. Is this expected? 6 comments 100% Upvoted
The roaming switchover time is a key factor that affects WLAN service experience during roaming. When the user uses the WPA2-802.1X security policy and supports fast roaming, the user does not need to perform 802.1X authentication again during roaming and only needs to perform key negotiation.
Disabling Fast Roaming doesn't reduce your ability to use 5 GHz networks. They are two entirely different things. I *only* use 5 GHz at home yet don't use fast roaming. Utilizing a single 5GHz AP is wholly impractical in a great many properties, hence the use of multiple APs. This is why we have fast roaming.
