I very much hope I'm wrong but it sounds pretty fishy to me. When the guy in the audience asked the question about what modulation this new radio uses he got a marketing babble answer unworthy of a university audience. Working in sensor networks we could really use one of these breakthrough technologies and in the past year or two I've heard at least three vendors give the exact same pitch but as of today there's no…

Also, transmitting 30 miles. Is this an unlicensed frequency?

They have developed on amateur frequencies since the FCC denied them an experimental license.

So, 5.8GHz or 2.4GHz or 900MHz, or what? Are the 40s (MHz) still available?

I wonder how this beats the curvature of the earth, or is it being bounced of the ionosphere, or penetrating through the earth?

It is either a lost work of Tesla or a bad version of this Douglas Rushkoff novel...

The are using amateur radio to test their new radios because that is the only license that they (and almost anybody) can get in the United States. He explains this in the video. They didn't want to go to a country more open to testing, so they used what they could in the US.

They are using the HF (3–30 MHz), VHF (30–300 MHz) or UHF (300–3,000 MHz) range because that is what the amateur radio license allows. http://en.wikipedia.org/wiki/Amateur_radio_licensing_in_the_...

They are not beating the curvature of the Earth. If their claims are true, they are doing something other than frequency modulation. The electromagnetic signal is not RF so it interacts with large bodies (Earth) differently. There is no way to know if that is true until they demonstrate.

I think the meaning of 'law' has been lost here. When I was doing my masters in Info./Comm theory I remember coming across a much ridiculed paper that claimed to break Shannon's law. It was pretty funny but of course I can't find it now since a google search only turns up hits for this.

Can you really call something like Roomba a revolution? I've met a single person in my life with a Roomba. People everywhere still sweep manually.

You have to look at it context - not every market works as quickly as the consumer tech market.

In the vacuum cleaner market there have been two major revolutions in the last 30 years.

The first was the Dyson. It was launched in 1986 and has slowly taken over the high end vacuum cleaner market.

The Roomba seems to be following a similar path. I know a few people who use it, and it has been a huge success for the company.

Sounds like interferometric based MIMO from the description. Not breaking Shannon's law in that case.

It is, I've been doing a bit of poking around in the patent applications filed by this guy recently and that seems to be the gist of it. Unlike normal MIMO though, only the base station has multiple antennas, the mobile stations have one antenna each. This leads to the downstream bandwidth being much higher than the upstream, but given that video is going to drive mobile bandwidth growth that is ok. Basically what's…

Can get the pdf here. Nice, Mvandenbergh! http://www.google.com/patents?hl=en&lr=&vid=USPAT741... and here http://www.google.com/patents?hl=en&lr=&vid=USPATAPP...

Dyson has taken over the consumer end of the market. Professionals do not use Dyson. Dyson doesn't have anything high end.

I see most of those as "revolutionary" applications of existing technologies/hardware. When I said hardware maybe I meant "technology"?
