A FAST ROAMING PROPOSAL was recently adopted by IEEE on an overwhelming vote that was written by Dan Harkins (coauthor of IPSec.) I believe it spells out a 50ms handoff which is quite acceptable for delay sensitive data streams like VoWIP, multicast, Internet Radio etc.)
But it's up to the client to make the AP association decision until the Radio Resources Working Group comes up with something to give intelligent WIFI switches some control over the client. I can dig up more info if anybody's interested...cheers...

The two APs have yagi antennas pointed at each other, They have a clear line of sight, they are running on different channels. No encryption. No negative radio interference. A person in a car with appropriate wifi gear is listening to a streaming internet radio station at point A. He leaves point A for point B at 65 mph. As his card transitions from one AP to the next, will he experience a distracting interruption in his internet radio stream? I am hoping that most wifi cards have a mode where they will automatically connect to the AP with the strongest signal. I just wonder how fast a handoff can be made. All thoughts on the issue are welcome :-) thanks Chris White
