E.g., I have the cheapest linksys AP, and it doesn't seem to have any brains in that dept ?! 2. some proprietary scheme ... 3. IAPP, or Inter-Acess Point Protocol, which seems to have two parts ... an exchange of UDP beacons between APs that allow them to set themselves auto-magically to different channels, and a handoff protocol so that in theory packets for a node that was associated with AP A can go to AP B. Any comments? I suspect cheaper APs support #1 ... Lucent does 3. Cisco does ??? regards, Jim Binkley jrb@cs.pdx.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
