No in the private sector, I have used a smattering of 802.11b devices in our
plant.
First warning, 11Mbs is very optimistic. Via straight file downloading I
would put
it best at 4-5Mbs. If you want that, <100' in a steel building. We have
found a
firmware power hack that brought it the WAPs up to 100mW. I can stay
connected
up to 300' in the same steel building now.
We run Netgear Wireless Access Points and either linksys cards or Orinocco
cards.
Orinocco still makes DOS drivers. :-)
Feel free to reply,
Shane

Subject: 802.11b signal ranges
Can anyone give me some results of testing your wireless setups? At what
distance did the raw data transfer rate drop from 11Mbps to 5.5, 2, &
1Mbps? I have bounced my brain of google and the rest of the Internet a few
too many times and can't seem to find a straight answer. What I have seen
repeated over and over is 150ft (30m) but some say this is the indoor range
and some say this is the range that the signal can still broadcast 11Mbps.
I would like to see the results you got either way but ideally I would like
to see tests that occurred under about the following circumstances:
-a COTS (Commercial Off The Shelf) wireless base station (we are using
Cisco aeronets (and a few Apple Airports spread out here and there), but
just let me know what you used) Please no antennae!
-Open air environment without a lot of buildings on either side that the
signal might bounce off of (I know that this isn't a very real world
situation but I am interested in a wireless setup's raw transmission
capability
-COTS wireless card, just let me know what type of card you used
Thank you very much,
