New WiFi Link Distance Record
Espectr0 writes "A Venezuelan professor along with his team have set a new record for the longest WiFi link. Using commodity hardware, they established a connection between a PC in El Águila, Venezuela, and one in Platillón Mountain, a distance of about 237 miles. The previous record was 193 miles. Slides [PDF] are also available."
Using a directed wireless transmission is certainly far cheaper in such remote regions. Think of the equivalent cost of building and maintaining 250 miles of land line!
What if the Hokey Pokey really is what it's all about?
They are not making any innovation in RF, but they are testing a new experimental MAC protocol from Berkeley that provides higher throughput for long-distance point-to-point links.
Neither, if you read the PDF about the experiment, you'll see the aim is to discover whether stock equipment can be used to connect remote areas to the Internet. Connecting people in rural locations is a challenge being faced in many countries, others have different solutions.
Really, I consider myself a bit of a leftie and I'd like to see Mugabe slung out of power as much as any Tory would. Comparing Mugabe to the liberal left is like comparing Karl Marx with Ronald McDonald: pointless and stupid.
I'm going to transform myself into a mighty hawk. Either that or I'll just go and work at Dixons, haven't decided yet.
3Mbps with the TIER equipment sustained in both directions 0% packet loss shown in the 'ping' output.
The Linksys (WRT54G) equipment that had 65kbps sustained in both directions had 1% packet loss over 58 packets (one lost packet).
In all, they both were sustained and stable connections, but the TIER hardware was a far better connection in terms of speed than the Linksys hardware.
...and that's the way the cookie crumbles.
As one of the crew that ran the Wifi Shootout in Vegas a couple of years ago, I can say that there won't be another Defcon Wi-Fi Shootout any time soon. We simply ran out of Line-of-Sight locations. I'll tell you right now that the iFiber Redwire team could have established that link were they to have the LoS.
you can get a signal to and from orbit without using a dish, but thats putting out 5W, and the same with point to point microwave links of the 1950's, a lot higher power than off the shelf wireless gear and no amp

I have the Darwin Awards book right here, and it lists that story as a hoax.
A friend of mine who's a military history buff told me a story about Soviet fighter aircraft in the 70s and 80s. Seems they had very powerful look-down, shoot-down radars and pilots were instructed to turn them off during take off and landing. Apparently sometimes they forgot, and runway maintenance crews had to regularly pick up the carcasses of rabbits, birds and other unlucky critters that were in the area when those MiGs went on missions.
That's what we engineers would call "complete cobblers". The power intensity required to cook anything is remarkably high, and requires some time - your microwave oven takes some minutes before the "ding". Also, the frequency at which a microwave oven cooks is chosen because it resonates water molecules. The last thing you want is radar that can't "see" through clouds!
