Fast-Roaming-Over-the-DS

With Fast Roaming over-the-DS (Distribution System) you can activate an option of the IEEE 801.11r standard, which takes advantage of the LAN connection between the access points. The roaming request is sent to the access point that the client is connected to. The AP forwards the request to the new access point and the swap is performed. This means significantly faster roaming speeds than possible with the usual "over-the-air fast transition", which is a big benefit to real-time applications such as VoIP.
