| The message could be encoded in carrier waves, modulated signals like those of AM or FM transmissions, or in pulses that would carry further given the same amount of energy. Unlike conventional wireless systems, which use narrowband modulated carrier waves to transmit information, Ultra-Wideband transmits over a wide swath of radio spectrum, using a series of very narrow and low-power pulses. Electronic phase modulation of this kind will work well with fairly long-term processes, but electronic carrier waves have fairly low frequencies. |
