Robert Cain says:
Remember that a "modem" such as we are used to is a much more complex device (at least the firmware, and you do pay for that :-) than what is required for simply modulating and demodulating a fixed rate, framed bit stream.
Perry E. Metzger sez: This is embarassingly wrong, Robert.
Please embarass me. Do you always approch things with the hostility I am sensing, Perry? I've heard this about you but this is the first time I've run into it myself. :-)
Have you actually looked at one of the Rockwell chipsets in real use, Robert? They have "all in one" solutions these days. Getting cheaper than what they sell is almost impossible -- you cannot achieve savings by "leaving things out" because there is nothing available to leave out. With the cost of a codec to do something like QCELP and the chip to do the encryption, you are going to be at least as expensive as a normal modem anyway just for the parts to manage that component of the work.
Yes, every chip set and DSP on the market in excruciating detail. It was only recently that I realized that I could use a simpler, cheaper solution. I'm an EE as well as programmer and I've actually got bills of materials and schematics for this. I'm not guessing.
I'd be very suprised to see your price predictions come true. I'd be less suprised to see a secure voice product becaue the mechanisms to build such things are well understood and hardly revolutionary.
And I'll be very happy to surprise you when the political dust has settled, when I am satisfied that a patent filing isn't going to be stamped so that even I can't look at it or talk about it legally and when I find the bucks to patent it and build one. I keep saying I won't argue and then I do. :-) Time for me to put up or shut up. I've tested these waters to my satisfaction and from the feedback here believe that my solution is still non-obvious (until you see it :-) So, I'll be back to discuss this further when I can freely.
