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."

evidence that the US didn't plan 9/11?

Can anyone give me any evidence that the terrorism was not the act of the US government? Or, for "innocent until proven guilty", that it was the act of someone outside the US government, the prime suspect in terms of being the only entity immune to its own intelligence services.

Explanation of why passenger lists didn't have the named hijackers would be a good start.

Thanks.

Contraceptives. If this doesn't make you sterile nothing will.
