Advantages
The combination of larger spectrum, lower power and pulsed data means that ultra-wideband causes less interference than narrowband radio designs while yielding low probability of detection and excellent multipath immunity.
This wide spectrum signature also provides UWB with even greater advantages like very precise range information, which could be used for security purposes in a WLAN/ WPAN environment, as well as a strong capability in sustaining very high levels of interference from other narrowband devices.
In addition, UWB systems are much less complex, allowing for significantly lower cost and smaller size, since they don't use any RF/IF conversion stages, local oscillators, mixers and other expensive SAW filters common to traditional radio technologies. Broad consumer adoption of wireless networking technology can finally become a reality thanks to ultra-wideband.
