I'll have to take a look at this and get back to you.

Sorry for the delay in responding, but I've been busy with other projects. I took a brief look at the site you mentioned, time-domain.com . I'm not sure I accept all their claims but I will make a few comments.

First, I don't think they are violating the Shannon-Hartley limit, something IAS has claimed. There are 2 ways of increasing the bps (bits per second) of a signal, one of which is to increase the power, and the other way is to increase the bandwidth of the signal. (They mentioned using UWB [ultra wide-band] signals, so they are doing the latter.)

Second, UWB technology is already being developed for other purposes. For example, if my memory is correct, the Defense Advanced Research Projects Agency (DARPA) is doing a UWB radar project code-named Mountain Top at a remote location on the White Sands Missile Range in New Mexico. DARPA's objective is to build a radar to detect low-observable ("stealth") aircraft and missiles.
