  • No infrastructure support, commodity phones
  • Real-time measurement

– Low measurement time: <=100ms – High measurement frequency: > 10 times/second

  • Accurate

– Centimeter level accuracy

  • Robust

– Mobility: Up to 4m/s hand-to-hand speed – Environment noise: talking, laughing, shouting, walls, …
