2 2 Why UHF (860 MHz )? UHF operation power magnetic field UHF vs. inductive Longer read range Small antenna (50 MHz, 20 GHz. Mobile-phone-size reader Reading independent of direction and orientation. Interrogation field can be focused. Faster communication UHF tag works also on metal when needed Far away, the power transmitted by radio waves decays as 1/r 2, whereas that of magnetic field as 1/r 6. distance [m] power [W]

3 3 US Embassy (Suurlähetystö) Sound Waves Wall First passive RFID sensor application by the Soviet Union in the 70's) (Ensimmäinen Neuvostoliiton sovellus) High Microwave Power > 10 W 10 m - 20 m RFID communication is based on back scattering

4 4 Laminate Microchip Antenna ● Readers - Radio Frequency transmitter (power + communication) - Emits power levels similar to cell phones - Operates at unlicensed RF frequencies - Can uniquely communicate with many tags in the field at the same time (anticollision) - Can share the band with other wireless technologies ● Tags - Composed of a small microchip and antenna - Are powered from radio waves – no batteries - Have field read/writeable memory - Communication is based on back scattering - Have a communication range up to 10 m - Can be read without line of sight - Can be made for 100M/yr - Number of unique codes unlimited Power + data Communication by back scattering PASSIVE UHF RFID TECHNOLOGY
