  • Selected TecSpecs:
    • Data Transfer Rate: 100Mb/s, should reach 500Mb/s by 2004
    • bit-like RF signals, one single wave
      • frequency and pulse duration are thus trivially linked
    • has no dedicated (carrier) frequency
      • also called "carrier free" or "base band" radio
    • Power: ~1mW
    • Pulse spacing: 25-1000 ns on pulse to pulse basis, based on channel code
    • Bit coding: monocycle sent 100ps early: 0 -- 100ps late: 1
  • Frequency band under discussion with interest groups (manufacturers) and FCC
    • See FCC 02-48 report, April 22, 2002
    • Probably >2 GHz for data transfer
    • special requirements for other applications at lower frequencies (imaging)
