I'm just learning. I read a bit on UWB and saw that it could transmit audio and video over short distances, like between components in a living room - TV, stereo, DVD, VCR, set top box etc. I thought ZigBee was low data rates - not high ones like for video signals - and low power/long battery life. But if ZigBee does use, or can use, UWB, all the better.
