association with access points

Hi All,

I am working on a project and have bumped into this problem. I had
heard from someone that a wireless card can associate with two (or
more) nearby AP's at the same time. It does this primarily to peroform
smooth handoffs. However, I am trying to search for the details on how
this happens but have found none.

So...my doubt is if this is at all possible and if it is done as the
standards are specified today. If it is, where can I find information
on it.

Thanks for your help,
Regards,
Vipul
