It's been quite a discussion here on the list. There has been much
good information and some very well written misinformation. It seems
that we've agreed to disagree. For my part, I'll weigh in and say that
I have logged data relating to WiFi stations. (I've inhaled!) I'll
also state that I have no interest at all in accessing anyone's
network. However, I find the explosive growth of this technology to be
fascinating in many ways and I'd like to list a few.
Topics such as AP density, propagation charactaristics, channel usage
patterns and co-channel interference are all interesting. So are
throughput and backoff/retry characteristics in high density areas.
Statistics about how the usage of WEP has increased over the past
three years are also interesting. As well as the increase in the
number of networks that people are INTENTIONALLY leaving open.
It is also interesting to correlate WiFi density to popluation density
and demographics; as well as to compare consumer and commercial
adoption of WiFi.
The data can show intersting information about the market penetration
of various vendors and chipset manufacturers. And show how different
parts of the country favor one over the other. Or how it varies
between consumer and commercial users.
How quickly are users migrating to 5GHz and what areas are the first
adopters? How is spectrum being utilized and what kind of forecasts
can be made about it?
These are the types of things that interest me and none of it is
illegal. The data that "wardrivers" collect can help to answer some of
these questions. All of the data can be obtained passively without
ever transmitting or actively engaging a STA.
Just because one can put a radio in the car and collect raw data does
not automatically mean they are doing something illegal. Drew and
others have tried to make this point repeatedly. The FBI have also
been clear on this matter -- simply associating to an access point is
not illegal.
In a similar way, I also think that the cellular companies have built
some pretty amazing networks. If I had the time, I think it would be
interesting the take a receiver or spectrum analyzer and drive around
mapping the various cellular towers and their radiation patterns. It
would be really interesting stuff and also completely legal. Yet it
would be exactly like "wardriving."
According to the views of some on this list, if I told everyone where
the Sprint towers were, it would be like giving them free reign to go
terrorize them. Oh, wait, I can already look all that data up on the
FCC website. So much for it being illegal to publish where radio
transmitters are.
Yes, there are lines that can be crossed. Don't cross them. Just have fun.
