Agreed. There is still a long way to go before this can see the light of day.

I agree Bert22306, we need to know more about this 10dB claim because it looks impossible.

It would be interesting indeed. However, we do have Shannon's equation to compare it to, and we do know how close to the Shannon limit other existing techniques come. And we also know that MIMO, under conditions in which multiple propagation paths are very uncorrelated, can give the appearance of violating the Shannon limit, but actually does not.

So, when we get more details, a fair comparison can be made. Anything that is 10 dB better than existing possibilities, aside from MIMO, sounds like it violates the Shannon limit, to me. Aren't we capable of only a couple of dB from Shannon already?

It would be a true breakthrough if it did legitimately violate Shannon's limit, but that wasn't mentioned.

Bandwidth Breakthrough

Reminds me that UWB (Ultra Wide Band) fiesta back in 2002-2005, more than 20 modulation schemes are proposed from a number of startup companies with pretty smart people, but sadly, practically none of them survived. The "most popular" UWB scheme was so-called MB-OFDM, similar to WiFi but using faster keying speed (312.5nsec VS 4usec of WiFi), thus wider subcarrier bandwidth. Anyway, even MB-OFDM UWB did not make breakthrough as proposed Wireless USB standard.

This sounds very interesting, but this is a long road with the corpses of a lot of startups alongside of it. Until they go public with details it is going to be hard to see whose ox is going to be gored by this and if it will actually make it out into the world, and if it does, in what form. There are a lot of players in spectrum that have the capability to buy and bury inconvenient technologies or the political wherewithal to block them.

It seems like a major challenge that companies have to face to have to standardize their communications technology before they cand eploy it and to have to reveal through disclosure much of their advantage to their competitors in the process. It is worth aiming for smaller markets in that case.

A 10 dB advantage over 4096 QAM! Just when you think every clever modulation scheme has already been invented, someone comes up with a new breakthrough that shatters old barriers.

I look forward to seeing how this progresses through standardization & productization.
