What is 802.11r?or what is Fast BSS Transition?

Fast roaming,if you search this keyword on searching engine you can find many terminology of it,the most spreading version is as follow.

 “Fast roaming,also known as IEEE 802.11r or Fast BSS Transition (FT), allows a client device to roam quickly in environments implementing the WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another”.

Simply put,fast transition roaming is an amendment to the IEEE 802.11 standard that permits continuous connectivity aboard wireless devices in motion, with fast and secure hand-offs from an AP to another managed AP in a seamless manner. For ensure voice quality and network security, a portable station must be able to maintain a secure, low-latency voice call while roaming between APs that are handling other traffic.

The situation of apply fast roaming?

As stated above,when you have a high density WiFi network, use 802.1X (Radius Authentication), voice over IP, and your WiFi clients move around a lot,you definitely should be using 802.11r (Fast Roaming).But In a home network with multiple Access Points NOT using Radius Authentication, 803.11r Fast Roaming is NOT necessary,like if you only have 4 or 5 clients,in other word you do not have a high density network,you deserve have other better solution.
