Let's
clarify a couple of things on this wireless thing. Ethernet is a two way street.
Even if you get your cantenna to work, who is going to point one back at you?
There are two functions of the cantennna, or any parabolic or other kind of
signal collector/emitter, one is to focus and strengthen the signal that you are
transmitting. That you have well in hand. The other is to collect and focus the
signal coming back to you. At the distances you are talking, you will probably
need to have both ends focused and pointed at each other. Who's going to do that
for you over at campus? The other issue is that you will need line of sight. At
the frequencies we are talking about here, buildings and trees knock out an
appreciable portion of the range of the signal. You would need a pretty good
tower to get your line of sight. Does the university put these on towers, or
just mount them high up on the edifice of certain buildings? I don't think their
coverage on the north east corner of campus is very good right now. I could be
wrong, but that's not a particularly populated area.

Today I bought a Belkin Wireless Network Adapter
from Staples (great deal is going on for the next couple of days where you buy
it for 60 bucks, and get back 20 in mail in rebates), and I'm hoping to
amplify it using a cantenna or some such thing to hook my home pc into the
wireless Tigernet. I haven't bought the parts for the cantenna yet, and
am a little afraid to start taking the thing apart, especially since I don't
know if I could get the cantenna to work with it or get it back together, and
want to be able to take the thing back in 13 days or less
if this is futile - I don't have a full line-of-sight, and am
approximately 1.8 miles from University Hospital (measured the trip to work
the other day) by car (probably a little less straight). Have any of you
all been able to connect to the wireless network using similar type
things at this distance??? If so, what were you using, and how did you
do it? I'm located right behind the Stephens Stables off of Old 63, and
I think I may end up having interference from Boone Hospital, and one or two
building between me and the main campus. The box says that
max distance @ 11 mbps is 590 ft, @ 5.5 mbps is 984 ft, @ 2mbps is 1476
ft, and @ 1mbps is 1800 ft....
I noticed in some of the archives that you all
are working or mentioned on working on a project to put wireless
internet in the public library. That sort of cooperation with the
city is great!
Also, I've read that the wireless access on the
main campus is just Cisco. That makes me curious if it would be agains a
contract or something to use other company's stuff... because in the not
too distant future (sometime in first quarter of 2003) it looks like vivato is
going to be have wireless switches that are a heck of a lot more powerful than
the cisco stuff. I don't know the pricing yet, as the product is not out
yet http://vivato.net/
but from the few reviews and stories that I've
read tonight and yesterday - it looks like Vivato is going to be creating
switches that act like super powerful access points, and they will be able to
reach miles, not just feet....
