Spark Gaps and Ultra Wide Band Data Transmission
Embedded Geek writes: "It sounds like the revenge of Marconi, but Scientific American has a story about the use of spark gap technology for Ultra Wide Band (UWB) data transmission to send data at 100 to 500 Mbps across short distances (five to ten meters). As with every new technology, 'engineers expect these UWB units to be cheaper, smaller and less power-hungry than today's narrowband radio devices,' but there might be some truth to the hype. The secret appears to be the lack of a carrier wave, allowing use of wide swaths of the spectrum for transmission (the few comments I read at the FCC site referenced in the article addressed spectrum allocation)." Read below for a few more links, too.
"The article pitches the technology as a challenger or succesor to Bluetooth and 802.11a. There are several commercial companies investigating the technology (Aetherwire, Multispectral, and others are cited in the article) and Intel has a paper cited in the article. Spin off applications from the components needed to make this technology work might include a GPS style system accurate to one meter and a radar technology that would allow seeing through walls for construction, rescue, and (ahem) law enforcement."
Yes, and just think, at the same time you can have your internal organs melt from the lethal doses of gamma rays corsing (sp?) through your body.
(J/K of course, the idea in the parent post would be pretty cool, and I hope no meltage of organs would be involved)
My other sig is funny!
Yeah, but even though you are microwaving your body on a power of 1 you are still microwaving your body. And once you get cancer its too late. The way I look at this is similar to cell phones. If someone gets a brain tumor using a cell phone its their own damned fault. We've all been warned. But if you're affraid of UWB you should really be scared of 802.11a, often with ranges up to 10 miles. Imagine the radiation. Do you think a wireless internet is worth it? I do. *evil grin*
Strictly, there's nothing stopping UWB from operating in the gamma regions.

That's the sound of any credibility you had left going down the toilet.
I like petting kittens.
...better to be thought a fool, than to open your mouth and remove all doubt. You have no clue what you are talking about. It would be pointless to even begin to address the scope of your ignorance in this small forum. sit down, before you hurt yourself. or perhaps, go stick your finger in the nearest light socket, and get a taste of Tesla's influence.
