I asked
John
Tankard the same question a while back here is his
answer.....
"only difference is there is one set
of
freq's locked out <on the world cards> which allows
them to
work legaly in any country in the world, they say there is no performance
advantage, further they say becuase of a freq range being locked out it
means in
a multiple AP location, the cards can only span 3 AP's where the normal
cards
can span 4. The only country near us with this problem is France."
