"On 16 December 2002, the Rainmaker Technologies' Board of Directors appointed Mark E. Laubach as President and CEO...he was co-founder and CTO of Com21, Inc."

Have you any idea what Mark got wrong when he felt that Terayon's S-CDMA essentially would have no real value? He dazzled me with technical analysis of S-CDMA, though it didn't quite jibe with what I'd come to understand through reading George Gilder.
Now CMTO is way down, TERN is afloat and the first to sell DOCSIS 2.0 products with S-CDMA included. WTM Sherman has put some scathing remarks on this thread about CMTO.
Mark's Rainmaker Technologies has changed its name to Broadband Physics, Inc., and writes as follow:
"Broadband Physics' technology is based on a unique innovation in mathematics and provides the cable operator with a unprecedented significant gain in digital capacity at the same or better cost of today's and tomorrow's traditional silicon solutions. Almost 200Mbps per downstream channel is obtainable with our products as compared to today's almost 40Mbps"

To be critical, if I were proofreading the above, I'd write "AN unprecedented significant gain" instead of "a unprecedented..." I'd write "digital capacity at the same or better cost THAN today's and tomorrow's traditional silicon solutions" rather than " digital capacity at the same or better cost OF of today's and tomorrow's traditional silicon solutions." The "tomorrow's traditional" solutions bit, actually, I would'nt write at all. It is surely pure hype(sounds like what WTM Sherman was saying about CMTO), pretending to outstripe the unknown future today. Granted that Broadband Physics is a private outfit to date and it sounds great to boost Cable Capacity by some 5 times(didn't it used to be claimed as 10 times?). Broadband Physics is Partnered as a Panasonic Research Company, and sounds like a GREAT technology, re: "“We’ve got better mathematics”, says Chief Scientist Bill Miller. “With our technology, the limit moves closer to real world physics for getting the most digital capacity out of the existing cable network.”
Broadband Physics is in the process of completing its development and expects to validate SDM’s performance through engineering field trials early this fall."

The "real world physics" statement above, as I recall, relates to a criticism of Gilder I've read, i.e. Gilder didn't account for real world physics when comparing cable plant to telephone plant(DSL). Well, it seems that Mark probably would have agreed that cable plant has much better inherent capacity, and in any event he is now attempting to greatly improve the real-world capacity of both and more. This is exactly the kind of thing one loves to witness happening in technology/mathematics, and would be the sort of real world advancement in cable plant technology that allways seemed both possible and likely to arrive someday, to me.
But all in all, I'm not sure what to think about the veracity of Mark Laubach. Thoughts?
Here's Mark's very recent article about his Sub Band Division Multiplexing technology:
