The Coming of UWB Technology

September 6, 2022

Ultra-wideband (UWB) is the latest wireless standard moving to mass market adoption, some 20 years after the U.S. Federal Communications Commission authorized low power, unlicensed use of the band from 3.1 to 10.6 GHz. UWB, defined by IEEE standard 802.15.4z, can accurately determine distance and location, even in the presence of noise and multipath. This eBook provides an overview of the technology and explores several of its applications.
