Principles of UWB vTime Domain - Extremely short pulses - Very low duty cycle vFrequency Domain - Ultra wide spectrum - Low power spectral density - Acceptable interference with other users
UWB is a wireless communication technology characterized by transmitting data by transmitting a continuous pulse signal in a very short period of time [1]. Initially, Ultra-Wideband technology was primarily used in radar and military commu-nications to play an important role in stealth operations and precision ranging [2].

UWB is an IEEE 802.15.4a/z standard technology optimized for secure micro-location-based applications. It enables distance and location to be calculated indoors or outdoors with unprecedented accuracy – within a few centimeters – by measuring the time it takes radio signals to travel between devices. Along with centimeter-level
The use of very short RF pulses. Since short pulses have very wide frequency bandwidth, it is termed “Ultra WideBand” or “UWB”. FCC defines UWB as a 10 dB bandwidth > 500 MHz or > 20%. TDC’s systems are typically > 2 GHz and > 60%. Actual UWB Pulse and Its Spectrum.
