18. Rastreabilidade
• Onde está o meu objecto?
– Track
• Onde esteve?
– Trace
• Quais são os seus componentes?
– Bill-of-materials
• É autêntico?

19. Onde estão guardados os dados?

26. 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

27. IoT applications
• Health monitoring systems
• Distributed awareness to natural disasters
• Improve transportation
– Reduce carbon footprint
• Improve recycling
– Using product lifetime information

29. 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

30. RFID em acção

31. 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

32. Near-field RFID
• LF (Low Frequency): [30 .. 300] kHz
• HF (High Frequency): [3 ..30] MHz
• Inductive coupling
• Load modulation

33. Shower Analogy

34. Far-field RFID
• UHF(Ultra-High Frequency): [300..3 000] MHz
• MW (Microwaves): [2,5 .. 5,8 GHz]
• Wave coupling
• Backscatter

35. Lighthouse Analogy
