Long distance wireless project

post #1 of 15
Thread Starter 
Alright so heres the deal. I got a loft on the top of my grandparents barn. Its basically going to be used by me and my friends and for LAN's. The only problem is that the wireless router is over 200 feet away from the barn, and the walls of the house reduce the signal severely. I was thinking of buying another wireless access point to use specifically for this task. Heres an overhead map of the house to make things more clear:



The red dot is where I will be placing a WAP. The blue dot is where the barn is.

Here is what I need advice on:
-A decent WAP (54mb/s is fine.)
-An outdoor omni directional antenna. (I will be mounting this on the roof.)
-A decent Wireless bridge. (To bring internet to the switch in the barn.)
-Any other recommendations / things I need.

Also I was wondering, what side should I hook the omni directional antenna to? The side with the WAP or the side with the Bridge?

I was going to suggest creating a biquad antenna. All it takes is some copper wire, connectors, and an old satellite dish. It'll be able to pick up signals across a few miles if done right. Here is the thread. I bookmarked it a long time ago, but all the info is still good

If you use a biquad, like from satellite TV at both points you should be able to get the speed you need. Remember that a weak signal will really hurt your speed since packets will be lost. You will most likely need to large antennas of some type at each point.

Get this. It has an antenna. You take the antenna off and use a cable to route it to a biquad. I have one of these cards. They work very well for the price. I also have a really large antenna on it too.
Look at this guide.

The biquad antennas I mentioned would look pretty much like a regular satellite dish, and work pretty well. I found this guide to build a cantenna also. They're all over google if you poke around a bit. This one should be easy enough for the distance you're talking about.

So could I replace the can with a metal pipe, or pretty much and cylindrical metal object granted the antenna connection comes in contact with the metal?

Im not sure to be honest. As long as it meets the specifications that is in the link (look under or around the calculator part of the site) it should be fine. Like the article says, experimentation is part of the fun, so If you dont want to use a can, experiment with pipes. Note though that It'd probably need a pretty big diameter. Ill see If I can find a link to one with a pringles can, and edit my post.
