You are right that "Exceptional claims require exceptional proof."

You are also right that at this time, due to contracts with the private side
investors, the project details can not be made public. After all, when a
group of companies take a look at a research project grant proposal and
decide to give a consortium of schools several million $ to do the research,
they are not doing that because they are the proverbial "Good Corporate
Citizens"... They want to make money on the deal. More precisely, they
EXPECT to make money on the deal.

I don't think (I hope) that the investors will boil me in oil for saying
that Sunday, some of the grad students were working in the Faraday lab and
reached a 5 second burst of 125 Mbps over a 30 meter run in the 10 GHz band
with a 3 db bandwidth of 145 KHz. This has not been verified or replicated
as of yet by another team. Also note that the signal is very, well, messy,
with an unfiltered 65 db bandwidth closer to 145 MHz. However, they used a
fairly sharp band-pass filter when they measured their throughput... At
least according to the report that was sent to me last night.



Note that when this started out, you said:

In about 1989 there was a local ham (now SK named Frank whose last name and
call I can not remember now) who came to me with a design for a device that
would plug into a 100BaseT NIC and generate low power (about 50 mW as I
recall) at either 70 cm or 23 cm. He wanted my input on the protocol stack
(networking is my thing). Effectively, the device simply sent and received
TCP/IP over an RF Ethernet link. He had built a pair of prototypes that
worked very well. He then built a simple amplifier to get the RF up to about
10 watts and it worked very well between his house and mine, about 8 miles
apart, on J-Poles. We were able to get about 80 Mbps at 23 cm.
...
I wish that I still had the schematic for the prototype that he gave me, but
over the course 15+ years and 3 cross-country moves, I have misplaced them.
It would need significant updating... The prototypes were xtal controlled
and did not use SS. I would think (I am a network engineer, not RF or
electronics!) that the system could benefit from DDS, DSP, and SS
procedures.



This seems somewhat different than the "university research project".

Why the change in story?
