Outline
  • RFID Equipment
  • RFID PERFORMANCE MEASUREMENT
  • Algorithms
  • Evaluation
  • Application
rfid equipment
RFID Equipment
  • The Impinj UHF Gen 2 Speedway Reader
  • Impinj\'s Monza RFID tag
effect of displacement from antenna axis on read range
Effect of displacement from antenna axis on read range
  • Tag move away from the antenna axis the read range decreases
effect of distance from antenna on allowed displacement from axis
Effect of distance from antenna on allowed displacement from axis
  • The tag moves farther from antenna , the allowed displacement from

axis also increases

proportionally

algorithms
Algorithms
  • Person-object differentiation
  • Object ownership
  • Zone identification
  • Person identification
tag belong to person or object
Tag belong to person or object?

Object move only when carried by a person

transition=?

Define a suitable threshold person

problem
Problem?
  • An object belong to an active person might well exhibit far more movement than a sedentary

>

co movement
Co-movement
  • The movement of a tag is compare with the movement of other tags at the same point

object ownership
Object ownership

co presence
Co-presence
  • For each object , we simply keep track of the amount time .
zone identification
Zone identification
  • Individual workspace
  • Shared workspace
  • Reserved shared workspace
  • Common area
person identification
Person identification

Logging

  • Tag id of person person identity

object interaction
Object interaction
  • If environment is stable , the RSSI from the tag would also be stable
  • If object is picked up , this would change its distance and its orientation ,thereby causing the RSSI of its tag change
  • Differ at least 10 dBm interacted
