RE: [Full-Disclosure] Cisco LEAP exploit tool...

["Jeff Schreiner" <techlist@xxxxxxxxx>]

Ok, I see I need to clarify that statement.  I was not disputing the fact
that an RF transmission could not be extended to cover greater distances by
using a yagi, beam or parabolic antenna I know this and yes I also read that
section on point-to-point power limits.

The situation I was thinking of was of a wireless router or access point
with an out of the box physical configuration using the two supplied
omni-directionals (that most wireless routers come with) being mounted say
in the center of the 1st or 2nd floor of an office complex in a metropolitan
area.  Is it realistically possible to pick up a signal from 7 miles away
without any modification whatsoever to the transmitting station?

If so what type of setup would be required on the receiving end?
