[MLB-WIRELESS] A question on associating?

[Mark Aitken]

Hi People,

In a situation where multiple nodes connect to a single AP where they 
associate at different speeds,  does the AP revert to the lowest common 
speed of the entire connected stations or can the 802.11a/b/g protocol 
handle multiple simultaneous associations of different speeds?

Can someone point me to documentation relating to this?

Thanks

Mark
