Learn about Ultra-wideband (UWB) transmission - the most talked about application in wireless communications.
UWB wireless communication is a revolutionary technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance. This exciting new text covers the fundamental aspects of UWB wireless communications systems for short-range communications. It also focuses on more advanced information about networks and applications. Chapters include: Radio Propagation and Large Scale Variations, Pulse Propagation and Channel Modelling, MIMO (Multiple Input, Multiple Output) RF Subsystems and Ad Hoc Networks. Focuses on UWB wireless communications rather than UWB radar, which has been covered before. Provides long and short-term academic and technological value. Teaches readers the fundamentals, challenges and up-to-date technical processes in this field.

1.1 Fundamentals
1.1.1 Overview of UWB
Ultra-wideband (UWB) transmission has recently received significant attention in both academia and industry for applications in wireless communications. UWB has many benefits, including high data rate, availability of low-cost transceivers, low transmit power, and low interference. It operates with emission levels that are commensurate with common digital devices such as laptops, palm pilots, and pocket calculators. The approval of UWB technology made by the Federal Communications Commission (FCC) of the United States in 2002 reserves the unlicensed frequency band between 3.1 and 10.6 GHz (7.5 GHz) for indoor UWB wireless communication systems. Industrial standards such as IEEE 802.15.3a (high data rate) and IEEE 802.15.4a (very low data rate with ranging) based on UWB technology have been introduced. On the other hand, the Department of Defense (DoD) UWB systems are different from commercial systems in that jamming is a significant concern. Although R&D efforts in recent years have demonstrated that UWB radio is a promising solution for high-rate short-range and moderate-range wireless communications and ranging, further extensive investigation, experimentation, and development are necessary to produce effective and efficient UWB communication systems. In particular, UWB has found a new application for lower-data-rate moderate-range wireless communications, illustrated by IEEE 802.15.4a and DoD systems with joint communication and ranging capabilities unique to UWB.
