Crowded frequency spectrum has led to renewed interest in ultrawideband (UWB) radio technology. With a growing number of wireless electronic devices occupying finite bandwidth, UWB technology, also known as impulse radio, offers the potential to share the available bandwidth with broadband, low-power pulses. Such pulses can communicate not only large amounts of information across short distances, but directional information much like the radar systems that they mimic. If implemented properly, UWB radios can coexist with conventional wireless radio systems, appearing much like background noise to those other systems...
