another successful "long" range link

I see (and have myself made) posts occasionally asking about distance,
obstructions, etc. After advice in this NG and some reading on the web, I
started making a hobby out of creating links for other people. So, perhaps
a few readers might benefit from seeing scenarios that are easily
accomplished.

The most recent is a Linksys 54G AP with 2 clients (this is just an AP, not
a combo router/AP. There is a wired linksys router in the Host building,
though). One client is about 1.5 miles away and the other is about 3 miles
away. There is direct line of sight to the closer client and some mild
interfering objects to the further away one (three or four trees and a
couple of rooftops that partially obstruct perfect line of sight). The
access point was already installed so I added a 15dbi Omni to it with a
pigtail, 30 feet of LMR 400 cable, and gas discharge lightening protection
(and a copper ground). - - Both clients have antennas that are overkill for
the distance, but effective. Each client used a linksys 54G pci card,
pigtail, 50 feet of LMR 400 cable, lightening protection, and 24dbi
parabolic grid antennas.

The non-obstructed client has the full 54 megabits and the partially
obstructed client has 38. Thru-put is excellent for both and both maintain
their connection effortlessly. The connection for both can also be
described as low latency. Pings to a server inside the Host network are
10~ms for both clients.

Also mentionable, since the linksys has two antennas and they auto-switch:
I left one rubber duck antenna connected to the AP. Inside the host
network building are two laptops that are still able to connect and do not
seem to disturb the connectivity of the external clients.

Neither of these clients is at any great distance compared to what is
possible, and both are using much-higher-than-necessary gain antennas. I
was able to connect to the host AP from 5 miles away with my laptop -
Orinoco 54g gold card and a 12dbi cantenna with also excellent thru-put, but
the price difference between a 15dbi parabolic grid and a 24dbi parabolic
grid was not a whole lot, so the "customer" decided to go ahead and purchase
the more potent solution.

I hope some readers who are hesitating to try their own link because they
don't understand all the terminology or are afraid their link might not work
and they'll be out a few hundred dollars for the equipment (or a few bucks
and a bunch of time/effort if they decide to build their own equipment) can
benefit from this short narrative. My longest link so far (unobstructed
line-of-sight) is 13 miles with excellent thru-put. Shorter "neighborhood"
links are not very difficult to install and I think sharing resources
(files, game servers, you-name-it) can be beneficial to a lot of people who
might not think they have the capability to accomplish such a link. If I
can do it - - Anyone can.

Hi

I'm trying to setup a wireless network similar to the one in your first
scenario but
Wireless networking is just beginning to emerge in my country (South Africa)
and their is not a lot of people that no much about it.

Would you be willing to answer a few questions just to point me in the right
direction


Thanks
