Reopening the electromagnetic spectrum with ultrawideband radio for aerospace

Analog radio has been in use for 100 years, but the authors take a different approach to the radio spectrum. Discrete, low-power pulses spread over many gigahertz allow us to manage the spectrum by time, instead of frequency. Time modulated ultrawideband (TM-UWB) radio technology, implemented in Time Domain's PulsON/sup TM/ chip, offers far-reaching impact for new tool sets for the aerospace industry. PulsON/sup TM/ technology is based upon the precise correlation of discrete pulses transmitted across a 2 gigahertz or larger spectrum and processed in the time domain. This ultra-low power digital data stream can be used for voice, data, and video communications and new applications in geopositioning and precision radar surveillance. TM-UWB features ultra-low power, immunity to multipath (Rayleigh fading), spectrum sharing, virtual undetectability, and capacity for very high bandwidth and channelization.
