[this is where my knowledge about radio > *really* fades]. Life is never that simple. The total emissions of UWB are pretty low but their spread across the wide frequency range makes them incredibly low on any frequency - so very unlikely to interfere. The total emissions across the set of frequencies as a sum (with emphasis on some frequency ranges such as 2.4-2.5GHz) apparently matters much more than the emissions at one frequency for things like human exposure.
