A good example and it has an easy answer. If person A is using WPA with

do with encryption. It has to do with the
visibility of your network.
I'm not saying run without encryption, restricted MAC access etc just
try to see this one issue of range that we are discussing here.
Here it is again in even simpler terms for you Pat.
Greater coverage by your network = More people see it
More people see your network = more chance one of them may hack it
PS.
In reply to your -'If- -person A is using WPA with a strong pass
phrase, their data are secure.'-, your words. If that were true then
WPA is an unbreakable system which is a bold and stupid statement. The
only truly secure encryption system I know of is a one time pad which
is just not practical on a network system.
