Hi synchro: The Time Domain ultrawide band wireless technique is completely different from CDMA. It relies on the transmission of extremely short pulses, which are so short that they can be resolved among multipath arrivals. Some of the impulse radio schemes do not rely on any modulation of any kind to generate the pulses, which removes a lot of the complexity in transceiver design. I have not followed the patent dispute with LLNL carefully, but my perception is that the key developments in impulse radio did not originate from LLNL, but from Bob Scholtz and his research group at USC. He has a form of association with Time Domain (consultant or more), so that I am very skeptical about the validity of LLNL patent claims. As you may have noticed the FCC is considering the allocation of spectrum for impulse radio.

Hi synchro - check out the new SI thread about Time Domain. Lots of good information. Would welcome your participation. Regards, Phil Subject 27357

I like the technology concept, but I do not appraise patent projects without even the near prospect of significant products. Time Domain speaks of use in cellular phones in ten years. That is another way of saying they don't have the slightest idea. Companies that stress patents (ie, the ability to stop other companies from doing the hard work of implementation) tend to be lawyer intensive and turn me off. Time Domain apparently has some uses in sensors, though, and its wideband, low power does fit my "wide and weak" paradigm.
