WIFI With No LOS?

Kurai · 06-07-2005

I am looking to connect two nodes together over a distance of at most 1 mile (no highspeed internet in the area). We don't have line of site there are an acre or two of trees in between us. Multi-antenna are not possible and two towers might be a little bit costly. Do I have any other options?

Possibly older 915 Mhz WLAN equipment, but that will probably be more costly than trying to get a clear RF-LOS for 802.11b/g.
The lower frequency propagates better through foliage, and other obstructions, than the 2.4 Ghz frequency used in 802.11b/g.

A link of that distance with no line of site would be like wiping your ass without paper and not getting any shit on your hand. Chances are it can't be done, but if it can then it's pure f'n magic!

Well the only problem is the towers would have to be fairly large because of the trees are pretty big. wrzwaldo do you have to be so graphic?

You can't beat the laws of physics.. For 2.4 Ghz equipment you need RF-LOS to make a stable link.
Try to head up to the Welcome Desk section, read the posts there, then head down to the FAQ section and read the posts there. Chances are that you will feel more informed and better able to decide what to do then.

You haven't seen wrzwaldo be graphic yet.. Wait till he encloses pictures with his posts.. THEN you can talk about being graphic

. (And no, he wasn't flaming you or anything of that kind. He was just using an allegori to describe why it wouldn't work. It's called humor in his neck of the woods..

Ok I have done some research and I have to build 2 towers 24 foot over the trees because of fresnel. Now I guess I am going to look for some info on towers unless someone wants to link it to me

It all depends on what kind of finish and type of tower you want. Some people attach a high pole to the chimney, and others go overboard and purchase motorized towers normally used by the armed forces and others needing mobile antenna farms

Some of the hamoperators I know here in Denmark, have purchased old streetlight towers from the electricity company, and used those. Try to Google/Froogle for a vendor in your vincinity, as well as contacting the public utility company to check if they might have some obsolete towers for sale.

Being new to the forums I wil cut you some slack... but this forums seems to attrack people with moronic questions (yours is not one of these so do not feel offended..................................yet) and if we had a nickel for each stupid question, well.. we would all be retired.

The lower freq equipment will be the best bet,... that or you have to upset some tree huggers and use a chainsaw.
If you are truly out in the boonies.. have you tried direct Pc? aka the satellite internet? you might find that trying to stitch a wifi link from you to him using the lower freq stuff might be more costly and tougher than using a satellite link.

If you're planning on building towers and buying all the other gear you'd need, it would probably just be cheaper to have Fibre run between the two connections, it sure as hell would be alot more stable, and probably cheaper than doing anything else.

Couple of other options to consider.
Get permission to place a self powered repeater on a tower in the clump of trees. This would possibly cut your cost to a single tower.
Check with phone company as to cost of dedicated connection between the 2 locations. Usually phone co. charges by the mile.
You might even be able to find equipment to make the connection via power lines.
