> The technology is real and working here in the lab.  We are currently
> moving digital video MPEG2 packets over a lower speed Field Programmable
> Gate Array (FPGA) implementation.  The modulation is based on Wavelet
> transform mathematics, not Fast Fourier Transforms.  We are a fabless
> ASIC house working on a next generation modem system.
>
> Our application to the cable network space begins with fiber speed
> channels starting at 170Mbps.  The steep stopband nature of modulation
> allows us to package channels directly adjacent in the RF spectrum.
> We will be running at 10bits/Hz/second density.  Taken to the limit,
> the last thousand+ yards of passive coax in an Hybrid Fiber-Coaxial plant
> will have about a 1GHz passband, hence a 10Gbps aggregate data capacity
> with our technology.  The cable operator can choose how much is allocated
> for broadcast programming (will always be the most cost effective way
> to deliver programming), custom bandwidth (for VoD, HDTVoD, business
> bandwidth, e.g. T1's), and shared bandwidth (cable modem style) for
> the most subscriber cost effective.
>
> In the existing RF spectrum of deployed HFC plants, one cannot get to
> 10Gbps overnight, it takes time and revenue streams to finance.  Hence,
> we can be deployed to mine the most effective $'s out of the existing
> HFC RF spectrum in an incremental fashion while completely co-existing
> with current services. The cable operator can "grow" capacity where and
> when the need to.

> I'm in the process of beefing up the technology description on the

> book that Dave co-authored with Stephen Dukes and myself.

> And yes, we are a Silicon Valley startup currently looking for
> additional funding.  This is a great "buy low" time in the market.
