Want to learn more about UWB? ExtremeTech just published a big article about this technology:
We'll examine this phenomenon from both a historical and technical perspective. UWB is a technology based on physics and requires some mathematics and computer science to understand, but technology can be considered in a broader context.
It should be noted that this article is from the perspective of the WiMedia implementation of UWB. WiMedia® is the de-facto standard radio platform for ultrawideband (UWB) wireless networking. With efficient power consumption and high data rates, WiMedia UWB has been selected by the Bluetooth SIG and the USB Implementers Forum as the foundation radio of their high-speed wireless specifications for use in next generation consumer electronics, mobile and computer applications. Over 200 international member corporations and research institutions support the nonprofit WiMedia Alliance, developing specifications, certification tests, and educational programs.
