• UWB signals are not as affected by multi-path as narrowband signals, due to shorter pulse widths. • It has high data rates. • It has increased security (low probability of detection) due to low spectral power density. • Signals transmitted below the noise floor can be recovered due to inherent processing gain. These signals will be invisible to narrow band users allowing for more efficient use of the spectrum. • It has multi-path resolution leading to • It allows Multiple User Access for a given portion of the spectrum.
