Think this'll work? Broadcasting my network down the street via 802.11b...

I currently have a wired network, but I need to transmit it to a house about 200 meters away. It's only down the street, and I can easily see it from my driveway. However, I have 3 major obstacles:

1) My house is > 100 years old and is made of bricks and mortar. I've heard wireless signals won't go through this very well.
2) There's an above ground pool outside of the receiving house. The pool is in the line of sight. Water is also bad for wireless signals.
3) I cannot see the house from any of the windows in my house because huge trees are in the way. Trees are bad for 802.11b too.

I'm sure a stock 802.11b card paired with a stock router would have trouble recieving a signal from much further than my deck...

So, I'm going to modify the antennas.

I plan on getting a router with a removable RP-SMA antenna. The router would be close enough to the best window on the second story of my house so that I could mount an antenna outside or at least in the window sill using a 6-10ft pigtail. I was thinking about getting a Netgear MR814, but I found out that the current version doesn't have a removable RP-SMA antenna. What should I get?

For the recieving end, I'm probably going to buy this PCI card and hook up a cantenna to it.

I figure that I'll overcome the bricks because the router's antenna will be in a window or even outside of the house. I'm hoping the cantenna will be able to take care of the remaining problems...

Do you think these plans will work?

BTW, my home will stay on the wired network. I need the 100mbps transfer rates here. The wireless computer in the other house will only need about 1-2mbps of bandwidth.

You're going to be in trouble. Shooting that close to big trees is a problem due to the moisture content in the leaves. You're REALLY going to be in trouble when it rains.
 
Correct and actually even the wind blowing the trees will distort the harmonics, perhaps enough to cause you problems. Doesn't really sound like you have much of a chance of making this work. Your only chance is to make it through the trees. Water isn't just "bad" for EMR, it kills it for the most part and trying to get that distance through a single brick wall, much less multiples is also a no go. Depending on how many trees your talking about it really doesn't matter how much juice you put to the radiators. You'll have to try it and see. If you don't mind wasting money, or if you get your hardware from somewhere with a good return policy then you only lose your time. It might work, how reliably is another question but there is obviously a chance without seeing your actual path. I wouldn't have high expectations however. I'd expect failure in fact and be pleasantly suprised if you get it up and running.
 
Cantenna or 'scoop-tenna' on a pole on the roof?

Scoop-tenna link

Do you have Line of sight from the rooftops? Do you have a neighbor willing to act as middle man (repeater on his property)
 
There's no line of site from the two houses. Without the trees, there would be though...I'm not feeling confident about this at all.

No helpful neighbors (mostly old people who've never touched a computer) 🙁
 
You shouldn't feel confident. In fact, as I've already said, if your dealing with a number of trees in the path, you should feel fairly confident that it won't work. As I mentioned, without seeing the path I couldn't say with any accuracy but if your talking about what I would consider normaly canopy/foliage on multiple trees, at 200 meters then you don't have a very good shot at it. Just get gear with a good return policy for anything you'll buy moving forward and keep your expectations low. You may get lucky.
 
Hows it for what? If your asking would it be useful in an attempt to link two wireless devices at 200 meters through trees, then no, it would be worthless. The ONLY way you'll even have a remote chance of making that link, again only assuming what you mean when you say "trees", is with high gain, low beamwidth directional antennas on both ends. For covering your home it would probably be fine. For trying to make the link this thread is about, it would be a paperweight without detachable dipoles
