This tutorial traces UWB technology through history, regulations, standards, system implementations and commercial applications. Methods of generating and modulating UWB signals are described and set in the context of UWB proposals for IEEE802 Standards. UWB antenna, radiation, and propagation phenomena, including unique behavior in multipath are presented in contrast with narrow band radio. Examples of UWB link margins including data throughput versus range and system data capacity (up to 2 Gb/s) are compared with conventional and much higher power 802.11a/b systems. The future of UWB is a mix of wireless communications, precision positioning and radar. UWB can enable an accurate indoor adjunct to GPS with centimeter accuracy. Discussions of applications show that UWB capabilities make possible delivery of location-specific content and information, tracking of high value assets, security systems and various automotive and interesting home based "location awareness" systems.
