In some respects, UWB technology goes back to the dawn of radio and Guglielmo Marconi's early spark-gap transmissions.
在有些方面，UWB技术回到了无线电初现曙光和马可尼的早期火花隙发射的时代。

Spark plugs only ignite the fuel mixture near the sparkgap, reducing the combustion efficiency, and the metal that makes them up is slowly eroded as they age.
