  1. IPv6 Enabled IndoorPositioning System Mentor: Ralph Droms Asfak Rahman KINO

  2. IPv6 Enabled IndoorPositioning System What is kio? • Accurate and low cost indoor positioning applications • kio is utilizing Ultra-wide band (UWB) radio communication technology and Time-of-Flight (ToF) • kio's positioning error is below 30cm/1feet • kio system contains of anchors for ToF triangulation, nodes for moving object, network border router and optional wireless network monitors • It is possible to achieve node ranging rate over 10Hz  • Communication between radios is based on IEEE802.15.4-2011-UWB MAC standard supporting both ranging and IPv6 compliant data exchange

  4. IPv6 Enabled IndoorPositioning System Why UWB?

  5. IPv6 Enabled IndoorPositioning System Why UWB? Shorter frame TX time comparing to other radios more ranging per second For ALOHA, 97% of treansmissions are likely to succeed without collisions if total air utilisation is under 18%

  6. IPv6 Enabled IndoorPositioning System Our UWB Radio Mode: 850 kbps Channel = 4 Bandwidth = 1331.2 MHz Pulse repetition frequency = 64MHz Preamble length = 256 Preamble length acquisition Chunk Size = 16 Preamble code = 17 PHR mode =127octets TX Power = -41 dBm/MHz @900MHz Update rate = 12 Hz (complaint with 5% LDC regulation) • Mode: 110 kbps • Channel = 4 • Bandwidth = 1331.2 MHz • Pulse repetition frequency = 64MHz • Preamble length = 1024 • Preamble length acquisition chunk size = 32 • Preamble code = 17 • PHR mode = 127octets • TX Power = -41 dBm/MHz @900MHz • Update rate = 12 Hz (complaint with 5% LDC regulation)

  7. IPv6 Enabled IndoorPositioning System Software : • Contiki-OS • uIP 6LoWPAN stack • RPL routing • UDP • HTTP IP enables monitoring kios from anywhere IP positioning web application
