7. Radio
• ISM radio bands
– Frequencies differ in world regions
• Europe, Americas, and Asia
• LF/HF RFID or UHF RFID?
– Operating principles are different
– Near-field far-field boundary
• Lambda / 2 PI
14. 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. Conclusions
• RFID is a set of technologies
– No “one-size-fit-all” tag and reader
• All readers cannot and read all tags at all times
– RFID middleware challenges
• All readers should not read all tags at all times
– RFID security challenges
• RFID allows things and places in the physical world to
automatically generate data
– An Internet of Things
