Security and UWB

How secure is the Ultra Wide Band (UWB) wireless technology I'm hearing more about lately?

UWB was designed with security in mind. In fact, its signal is supposedly indistinguishable from regular RF noise due to its pulse sequencing technology. It communicates in very short bursts (measure in picoseconds or trillionths of a second), so a receiver has to know exactly when to listen in order to pickup the signal -- something that, at least for now, cannot be easily performed using "outside" equipment. It also has interference and jamming protection built-in with the way it transmits signals across a broad frequency spectrum. In addition, it has built-in encryption and physical security through its location sensing technology.
