Sparda Posted August 12, 2006 Share Posted August 12, 2006 You are going to need some directional wireless equipment, it's not exacly cheap. http://www.hyperlinktech.com/ have lots of equipment and you need a direct line of sight for most of the equipment to work. You will need one of the antenas at both ends, prefrably connected to APs so that the networks can integrate seemlessly (if you trust your firend to effectivly be on your LAN all the time).

rFayjW98ciLoNQLDZmFRKD Posted August 12, 2006 Share Posted August 12, 2006 Are you able to see your friends house directly? If you can, you can build two directional antennas using powerfull Wi-Fi cards (100 mw+) Quote Link to comment Share on other sites More sharing options...
Sparda Posted August 12, 2006 Share Posted August 12, 2006 Does any body know how widly supported so called network bridging is supported by APs? (By network bridging, I mean connecting two remote locations to each other using two APs which is transparrent to the computers on either of the networks) Quote Link to comment Share on other sites More sharing options...
OtterFox Posted August 12, 2006 Author Share Posted August 12, 2006 ok so i know nothing about wifi :oops: so can you tell me what parts i would need? yes there is a direct line of sight (ive got a 2 story house) Quote Link to comment Share on other sites More sharing options...
OtterFox Posted August 12, 2006 Author Share Posted August 12, 2006 ok i found this: Anyone can build an antenna for Wifi. An ordinary Wok will make a reflector as will an umbrella with a metallic film or even a Pringles canister if you want to fiddle around. What you want is a directional antenna with minimal side spillage and therein lies the rub. Without giving too much away, the reflector should be parabolic in both axis with about 7 degree or less beam width and 20dB or more gain (similar to what we offer) You should be able to polarise the signal to minimise noise from other transmitters in your path. Orienting the antenna at 45 degrees also helps. VOIP across Lake Taupo in NZ using ordinary laptops and PCs ?over 30km ?has been easily achieved. Regarding intecepts; Consider VOIP on an open system like talking in a cafe. anyone can hear and listen in even if they don't intend to. If you shout across the cafe and people between you hear things that you don't want them to, either shut up, use a different language or put up with it. It's your problem, not theirs.

stingwray Posted August 12, 2006 Share Posted August 12, 2006 Build two of your own antennas which as high dBi as possible. Then you'll need to text them out in a field that is big enough to check they work, don't want to put them up and buy more stuff with them not working. If your mounting them externally then you need to buy a lightening protector for them. Your last problem is that you'll want a really nice wireless card, and probably not a cheap SOHO wireless AP. We're talking 300-400mWs here, most cheap cards are 50mW which some going up to 100mW, you could then get an amplifer which would boost it, but then check what your local laws are on radio frequencys. So the problem is that you probably need a nice new wlan card, which means you'll have to make your own router, so probably an old pc if you have one. You could go with an amplifier on a SOHO router but I wouldn't trust it to do the job. Obviously this needs to be done at boths ends.

cooper Posted August 12, 2006 Share Posted August 12, 2006 Got a link to a site with instructions for that antenna, and how you're to connect it to a wireless card? I've never, ever dabbled with Wireless (too insecure for my taste), but I've got some interesting targets for attack in my vacinity. I doubt the regular antenna will pick up enough as-is, but with an external directional antenna things might get mighty fun. Quote Link to comment Share on other sites More sharing options...
metatron Posted August 12, 2006 Share Posted August 12, 2006 If you have line of sight then you can make yourself a couple of dish antennas and modify a couple of Linksys WRT54G to do the job for around $150. http://www.engadget.com/2005/11/15/how-to-...d-dish-antenna/ EBay, local papers and car boot sales are your friend. If you don’t have line of sight you can still do it, by buying high powered equipment and antennas (very expensive) or by doing something called Packet radio, which is not easy to setup, but can be the cheapest option. http://en.wikipedia.org/wiki/Packet_radio Quote Link to comment Share on other sites More sharing options...

metatron Posted August 12, 2006 Share Posted August 12, 2006 If you have line of sight and are looking for something more secure and faster, free space optics is an option. It’s not cheap but it’s fast and easy to setup. Quote Link to comment Share on other sites More sharing options...

Just keep your eye out for an old dss or whatever dish and follow the instructions from the engaget link above. I did just that with my 1.5ft diameter dss antenna and was picking up APs from over 8 miles away with my d-link dwl-520+ pci card on my linux box. Quite impressive in my book.

Blunderboy Posted August 16, 2006 Share Posted August 16, 2006 here is a sweet make it yourself antena that from the looks of it is pretty inexpensive. http://www.instructables.com/id/EQARE4I72GEPUCHTHU/?ALLSTEPS I myself haven't done it yet but I have a couple more fun things to do before I build this. Good luck and have fun. Quote Link to comment Share on other sites More sharing options...
PoyBoy Posted August 16, 2006 Share Posted August 16, 2006 You can easily up a Linksys WRT54G's transmit power up to 250mW +/- with the DD-Wrt firmware. You run into major heat issues when its transmitting that powerfully though Quote Link to comment Share on other sites More sharing options...

bootdsc Posted August 31, 2006 Share Posted August 31, 2006 OK you should check out this site http://www.wardrive.net/ for info on making all types of wifi antenna's. here is a antenna i think would work nicely for what you are trying to acomplish http://www.seattlewireless.net/index.cgi/CardboardHorn now to make this a even cheaper antenna you can just place the rubber duck antenna that is on your router right in the box at the end of the horn antenna...here is a nice crappy paint illustration as for what hardware to use you could use any router and buy a wifi repeater but remember they do not have a vary high power output so you might want to just spend the money to get two linksys wrt54g's. For testing you could just make one horn antenna and then point your router/antenna down the street and walk down the street with a laptop/pda to test how much range you are getting from it. now remember this will work much better when you have good antenna's at both end of your link.

metatron Posted August 31, 2006 Share Posted August 31, 2006 If someone is going to buy repeaters they might as well buy a amplifier. I built a 50 watt amplifier with preamp, it’s completely illegal to use in the UK and was based on one made by SSB Electronic, you can pick up a 3 watt amplifier for around $200.

bootdsc Posted August 31, 2006 Share Posted August 31, 2006 50watt? hah you are full of shit my friend, we are talking about 2.4 Ghz here not HAM radio Quote Link to comment Share on other sites More sharing options...
