Researcher Ermanno Pietrosemoli has set a new record for the longest communications link using Wi-Fi: 238 miles. Pietrosemoli used a combination of Intel gear and "off the shelf parts" to connect two computers in the Andes, seeing 3Mbps connectivity between them. The record was 137 miles two years ago. Slightly more information is available at APC.org.

Re: wow ... 238 mi

Might be good for someone that lives off into the mountains... connect devices / towns over WiFi.

It's an interesting experiment but I doubt this would be reliable at all.

Re: Two words:

I would agree.. at that distance, sites, must be laser sighted, and hope a bird doesn't fly past, or clouds/fog gets in the way.

I agree . . . not many interfering microwaves or cordless phones in the Andes, I expect.

Would the same thing happen to WiMax?

Re: Two words:

It happens to any microwave system...even those on relatively "low" frequencies in the 900 MHz region. The radio signal literally bounces off of water droplets and that scatter increases the attenuation along the path just like shining a spotlight through fog lights up the fog and not so much the target.

A 382 kilometer long path in one hop is just asking for it.

Neat and all but...

Not very practical. But very cool. A slight breeze and the high gain antennas are out of alignment and you start all over.
Congats on the record !

If only the Verizon CSRs worked this well.

Re: Neat and all but...

I get my access solely thru cantennas and ddwrt Linky routers so this is certainly progress. I am a p2p user enjoying the anonimity of wireless access so those pesky **aa's cant catch me. This break thru means friends within 238 miles can share in my Vast Library of content. Now if they could only get that bit rate up, I could be all the more generous. Its still a drag though, that I can only be as magnanomous as my equipment lets me.

wow, that's a pretty neat link, and 3 meg isn't bad at all, for that distance.

Still, at such a long ways away...it starts losing its effectiveness or feasibility.

not really, it just demo's the fact you can get that far in one hop, all you do to make it more stable is place a repeater or another guy in the middle or better yet just use the free MESH roofnet software and put a few more in between and your link gets far stronger.

hell, why not put up 3 seperate wireless routers on the 3 seperate channels and then bond them together.

the posibilitys are endless and lots of fun.

non power plug required even

I read the wrong one, and should be flogged with the huge antenna they used to create this link!

I'd rather see fiber...

Impressive.. but what would be really cool is if they had a "Fiber To The Andes" initiative instead, so I can have 1 Gb/s while I'm scoping out the mountain range...

Re: I'd rather see fiber...

if you want only 1Gigit/s then just go buy any off the shelf wireless GigE for both ends, its not magic, or perhaps you can drag some fiber as you clime and attach a few of the new 11n and WiMax cards along the way, dont want to be restricting the future spped after all

Here I have trouble keeping an 802.11g link going reliably from my house to the house next door!

That's awesome. I'll have to read how he did it.

Re: Color me ashamed

getting next door, thats easy, if you cant manage that heres a simple cheap tip.

make yourself a reflector and place your access point in that, pointing in the direction you want the waves to travel.

eather a simple curved cardboard template covered in foil
»www.freeantennas.com/projects/template/

or even easyer, one of these
»www.usbwifi.orcon.net.nz/cnr.jpg

and remember..., ALWAY put your wireless kit as high up in your house as you can get,the loft for instance, or even outside if your trying to do long distance.

look to USB2 making two or more parabolic DIY ends and MAC match them together, »www.usbwifi.orcon.net.nz/

theres a new USB bit of kit to play around with now, but not in the UK as yet for instance for taking what you learn from this post and going longer range »www.usbwifi.orcon.net.nz/alfa.jpg
»dplanet.biz/alfa.com/product_inf···s_id=342

and dont forget to make at least two ,one for each end, to help increase that personal friands/community LAN your Azureus'ing that torrent far faster over the new shared wireless LAN and the combined BB connections of your friends.
