Impulse radio
Impulse radio involves generating a broadband pulse that varies over extremely short periods of time, and using filters to extract only the usable frequency component for transmission.
 Digital divide
Refers to economic differences between those people or regions with good access to information and communications technology, and those people or regions with poor access.
Radio frequency. High-frequency signals sent and received using antennas in wireless systems.
A pulse is a temporary change in a signal, either increasing or decreasing in comparison to a reference state.Short-pulse refers to a pulse that varies for a short period of time.
 Indium-phosphide high electron-mobility transistor (InP HEMT)
Invented in 1979 by Fujitsu Laboratories researcher Takashi Mimura (currently a Fellow at Fujitsu Laboratories Ltd.), this is a transistor made of compound semiconductors featuring excellent speed and noise characteristics. Using an indium-phosphide (InP) substrate results in higher speed and lower noise than with conventional gallium-arsenide. This is considered useful in high-speed communications and millimeter-band image sensors.
