Ultra Wideband Overview
UWB definition Spectrum, 3.1 – 10.6 GHz Large bandwidth, low power, short distances Uses Gaussian Pulses.
Frequency Spectrum
UWB History
History First used in 1901 Gugleilmo Marconi transmitted Morse code using spark-
gap radio transmitters 1960s to 1980s restricted to government use 1998 FCC legalized for commercial use
Previous Work
Senior Project 2007 done by Jarred Cook and Nathan Gove. Goal was to create a scaled down UWB transceiver.
Research done by other members of the scientific community.
