This is a time proven mathematically based theorem. Claiming they have done it is one thing, telling us how is another. If they really have then they must have it patented by now so no need to keep it secret.
I can tell you right now how to get more data through a 6 MHz TV channel; up the modulation order to 256 VSB or 256 QAM. The problem with that is the SNR has to be higher. As I remember from testing a PSK demodulator in the lab, 256 QAM needed an SNR of around 30 dB for error-free demodulation. If you think getting better than 15 dB for 8VSB OTA reception is problematic, try 30 dB.
Almost no one would receive any stations.
When I read this stuff my skeptical antennas go up. I want to know how something will work in the real world. This reminds me of some guy I read years ago who said that stations on the same frequency don't interfere with each other. Radio waves pass through each other with no interference so there's no reason why you can't have multiple stations using the same frequency. Of course in the real world we have to use actual radio receivers and they have no ability to discriminate between one set of radio waves and another using the same frequency. No receiver exists that I know of that can lock onto one signal and completely ignore the others. If such a receiver could be engineered then there would be no frequency shortage.
Maybe Perlman found a way to do this.
It was painfully short on any useful details, there really was NONE!
The worlds reaction will be like the caveman looking up and seeing an airplane overhead, saying nothing about his first ride.
When you go to town take your laptop with you and visit a WiFi hot spot or a local library if text explanations do not suffice.
No patent. They had to use Ham Radio Bands
for testing and their testing limit was ~ 30 miles from the transmitter which was as far as they wished to drive. FCC would not grant a testing license. (50 Miles suggested would work)
The first hour part you should be able to prove works by your experience via satellite going to:http://www.onlive.com/
As far as the BS level, this was a lecture at "Columbia University"
and what he has done before was truly well documented by examples in movies.
The limitations of the Shannon-Hartley theorem were explained away by "He asked the wrong question"!
I wish that more could be said, but what you and I want to hear was not in the presentation.
That does not take away from my suggestion to go to town and watch it.
The audio quality is not good so headphones or a very quiet spot is recommended.
The wireless information was mainly in the Q&A at the very end and the audio quality was really bad for the questions from the audience.
I listened to the lecture a second time and the long build up is painful if all you are wanting is the wireless part, but it is necessary to accept his credentials well documented by past successes to just not dismiss the wireless breakthrough.
Redacted, read parts of patent and understood very little but no carrier comment was mis-spoken or not understood in contex by me.
Good luck to anyone reading the patent, the figures are missing and as patents are not meant to be read, few will understand much like me.
Wait for the video that really describes this and what actually is built.
