I’d like MT to support something like 802.11F allowing for faster handoffs from AP to AP. This is not roaming which is provider to provider, but handoffs which are AP to AP withing the same provider.
in IAPP form. I thought MT already supported IAPP.
Obviously, being a Layer 2 protocol, it cannot cross routers and the wlan interface needs to be bridged to the ether interface (or whichever interface connects the two APs).
I never needed it though, so I never tested, but I believe it’s in there already.
IAPP is used between 802.11a/b/g access points to ‘share’ information about associated clients.
Imagine a situation where you have client Z connected to AP A.
When client Z starts to move away from AP A and moving closer to AP B, client Z initiates a roaming process. It does this by telling AP A that it is moving to AP B. Having received this, AP A coordinates with AP B to ensure client Z switches to the new access point as seamlessly as possible (ie. with as little lost packets as possible). It also uses this process to make sure client Z’s MAC address is not stored in multiple access points at once.
That is a very simplified description (possibly with some mistakes?) of what IAPP is all about. Think of it as the RIP of wireless
