  20. 20. The Internet of Things [Elgar Fleisch 10]• Machine-centric• Connects low-end devices• Trillions (1012) rather than billions (109) of nodes• Universal Identification – EPC• Universal Addressing – IPv6
  21. 21. IoT applications• Health monitoring systems• Distributed awareness to natural disasters• Improve transportation – Reduce carbon footprint• Improve recycling – Using product lifetime information
  22. 22. RFID• Automatically identify tagged physical objects• Collect attributes such as location and time.• Information systems can keep up-to-date – Greatly improve business processes – Data is dispersed
  23. 23. RFID em acção [Roussos06]
  24. 24. Tag categories• Passive or battery-less – Use only power provided by the RFID reader’s signal – Smaller, more flexible – $ 0.20• Semi-passive or battery-assisted – Use a battery to boost response signal – $5• Active or battery-powered – Have additional processing capabilities and autonomy because they have more power e.g. sensors – Longer range – $ 30
  25. 25. Near-field RFID• LF (Low Frequency): [30 .. 300] kHz• HF (High Frequency): [3 ..30] MHz• Inductive coupling• Load modulation
  26. 26. Shower Analogy
  27. 27. Far-field RFID• UHF(Ultra-High Frequency): [300..3 000] MHz• MW (Microwaves): [2,5 .. 5,8 GHz]• Wave coupling• Backscatter
  28. 28. Lighthouse Analogy
  29. 29. Other RF technologies[ How stuff works ] [ PWKits ]
  30. 30. RFID tags •UHF(Ultra-High Frequency): [300..3 000] MHz •MW (Microwaves): [2,5 .. 5,8 GHz] •Wave coupling•LF (Low Frequency): [30 .. 300] kHz •Backscatter•HF (High Frequency): [3 ..30] MHz•Inductive coupling•Load modulation
