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
This chapter provides a comprehensive overview of ultra-wideband communications, starting with its history and background. Next the dis-cussion turns to the concepts behind UWB technology, as well as its advantages and challenges in wireless communications.
In this paper, the Transmission-Line Matrix (TLM) method in the time domain is utilized to determine the group delay of two printed circuit UWB antennas. The first one is a recently developed, new coplanar-waveguide antenna [27], the
1 Introduction. There are multiple techniques for generating UWB signals with various data modulation and randomization schemes. This Annex describes frequency-domain and time-domain measurement techniques of power spectral density for UWB transmissions and for all types of UWB signals.
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
