Maxwell and Hertz are names familiar to nerds and ham operators alike, and contributors to the knowledge base that Guglielmo Marconi mined for his well-earned successes. When Marconi began experimenting with spark-gap radio transmitters, he fabricated a device that produced radio noise, his “signal,” over a wide range of frequencies. His Morse Code transmissions eventually gave way first to amplitude modulation, then FM and increasingly more sophisticated encoding techniques. He also inadvertently created an early form of what has become an increasingly important communications method, ultra-wideband (or UWB) transmission. In the past twenty years, UWB radio frequency technology has become a key technological problem solver for wireless communications, positioning determination, and remote sensing applications.

Implementation is relatively simple, and because UWB is not based on continuous wave (CW) transmission, as are conventional RF techniques for information transmission and reception, it does not use the relatively large power requirements of CW transmission systems. UWB is also less susceptible to deliberate jamming and incidental multipath interference, while providing better masking of in-channel radio emissions by ambient RF noise. This has made it ideal for military applications, but consumers and the home networking market will also benefit from this relatively new approach to wireless connectivity. Will UWB become a most valuable player in the commercial, consumer, and military marketplace or just a blip on the timeline of wireless evolution?
