[[DWM is in the final stages of testing]]

What happened to the prototype they were supposed to show back in June of 1996? If you've followed this company, you know that the SEC has charged Neldon Johnson and others with stock fraud -- see sec.gov because they put out a lot of hype before the demo that never happened, where they claimed they had a 6,000,000 bps modem that would work over unmodified phone lines. The SEC probably has a strong case, because they don't do things in a frivolous fashion.

I still contend, as I did around the time of the "un-demo" several years ago, that you won't get more than 56 Kbps out of an unmodified phone line (POTS), and that's already been done. IAUS has claimed that they can violate the known laws of physics and break the Shannon-Hartley limit as well as get around the Nyquist sampling criterion. To paraphrase IAUS, "You'll believe it when you see it!" which simply hasn't happened. If you could actually buy DWM equipment, I could buy any modem IAUS might produce and test it in the extensive labs at work with proper test equipment, including BER testers, packet generators, protocol analyzers, spectrum analyzers, etc.

There are technologies that will get more speed out of copper phone lines, like xDSL (see adsl.com but they require that the phone companies change their equipment down at the central office, thus negating the claim of higher speeds over unmodified phone lines.

But then again, what do I know? Oh yeah - I almost forgot that I work as an engineer at a company that actually builds equipment that phone companies buy!
