UWB is based on a discovery by Larry Fullerton (Time Domain's founder) that single radio frequency (RF) monocycles could be transmitted through an antenna; by precisely positioning these monocycles in time, a matched receiver could recover the transmissions, thus opening up a whole new wireless medium. The technique does not rely on sine waves, does not require an assigned frequency, and transmits data on random low-powered signals that are indistinguishable from noise. Time Domain compares it to sending Morse Code at 40 million dots and dashes per second. The technology can potentially transmit at 1 Gbit/sec. UWB can interfere with other radio signals, so low power is used; but doing so limits the range.
