We've got a head office in Melbourne Australia with a site office in San
Diego. Latency is a killer! Actually another one in Newcastle in the UK
too - we get about 360ms RTT to that. :-)
We're in the process of deploying the riverbed steelheads now, and
they're amazing. CIFS still isn't "fast",

If you have enough money to play with, you might want to look into
NetApp's FlexCache setup -- a filer at home with the primary data, and
another head with some disk remotely to cache the data from home and serve

After seeing how good of a job Xirrus was doing at LISA year after year, we
brought them in to take a swing at our 5200-seat auditorium. We had been using
about 20 Cisco APs on a wireless controller with directional antennas and low
power, but it simply didn't work out at all. Once we got abov

I've setup a fairly large wireless system. The event was at a conference for
about 10K of people. I the test setup went well at my work location. It did not
perform well at the event. Later, I found out that human bodies absorb signals.
You might want to read up on that.

All the better reason not to sit close to the AP, I suppose.

This reminds me of a line from an early Star Trek episode:
"Ugly sacks of mostly water" to describe human beings. And 2.4 GHz is
quite susceptible to water absorption, especially at 2.45 GHz.
Also remember that some things *reflect* RF, which can make a mess of
those nice antenna patterns that
Rob,
You might want to check into Robocopy too. You can opt to bring the ACLs
with if you like (if there is a domain trust, that would work), or skip
them if you don't care. There are a ton of options, and it can
effectively do a diff and only bring across the files that have changed.
The do
But that's where you get the best access. Get your priorities straight -
it's much more important to have a solid WiFi connection than it is to
keep from getting toasted! :-)

If you're setting up wireless at a tech conference-- (and the associated
internet link), I *highly* recommend this reading:

It's scary, somewhat amusing, and highly educational. It should give
you uh, a few things to watch out for :-)

Rogue AP detection can be very important, too. It's not just about security,
but also about stopping them from
interfering either at an analog RF level, or from taking up "transmit slots"
that you want for yourself.
I would ping the DEFCON netadmin folks, they did pretty well in Vegas the last

Oh neat, I didn't even know about the /MON option on robocopy. I need to
read the docs again, it has been a while.

Xirrus has run the network here (SCALE) for the last couple of years
(without being a spectacular success). I don't know why, but they are not
doing it this year. The budget does not extend to buying their type of
equipment.
