Techniques for modulating UWB pulses include Pulse Position Modulation and Pulse Amplitude Modulation.
The FirePRO LDR technology lets current and potential users of IEEE-1394 take advantage of 1000BASE-T (GigE) pulse amplitude modulation (PAM-5) signaling to achieve Gigabit transfers at distances up to 100 meters with CAT 5e, 6 or 7 cables at a fraction of the cost of optical fiber.
QAM enables data transmission at approximately twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error rate (BER) which, in turn, allows the transmission of the data collected to be passed at an increased rate utilizing less RF spectrum.
