Whatever happened to UWB? Ten years ago, there was so much talk about UWB, and how it would provide so much bandwidth, etc. And now it's nowhere to be found. One huge advantage of radio is that it can work through walls; "Li-Fi" won't.

UWB is used in the 803.15 WPAN (wireless personal area network) standards.

802.15 WPAN - It's kinda stalled for some time.
And UWB really did get good press with some very promising features / performance back in the day.
If I remember they ended up using it in some system for firefighters that can 'see' through walls, and it might've been used for such a system in the army as well.
But overall UWB didn't deliver on it's promise.

UWB is making steady progress in active tracking systems and passive tracking systems. I work for a company that does active tracking: http://pluslocation.com/.
PLUS is an offshoot of Time Domain, http://www.timedomain.com/. Time Domain does radar; I don't think they do any active tracking (could be wrong though). IIRC Time Domain is the company that did the see-through-walls system.
