(Fall 2012) Life Expectancy of Various RFID Tags (Active/Passive)

1,051 views

Published on

The purpose of this project is to conduct a literature review of different case studies to understand how the predicted life expectancy of RFID tags compare to their life expectancy in real world applications. The project researches some of the factors that affect the life expectancy of different RFID tags and some of the applications of different RFID tags across industries. Finally, the project also analyzes how would someone choose the right type of RFID tag based on the given requirements.

(Fall 2012) Life Expectancy of Various RFID Tags (Active/Passive)

  1. 1. LIFE EXPECTANCY OF VARIOUS RFID TAGS (ACTIVE/PASSIVE) The purpose of this project is to conduct a literature review of different case studies to understand how the predicted life expectancy of RFID tags compare to their life expectancy in real world applications. The project researches some of the factors that affect the life expectancy of different RFID tags and some of the applications of different RFID tags across industries. Finally, the project also analyzes how would someone choose the right type of RFID tag based on the given requirements. Dhruv Chhabra, Jason Widgery, Michael Brockly, Stephen Elliott OVERVIEW: • Issues affecting Active Tags: • Physical tag damage • Battery Life • Energy Consumption • Read Cycle • Operating Frequency • Transmission Range • Environment • Temperature • Moisture • Gaussian Noise • Burst Noise • Issues affecting Passive Tags: • Physical Tag Damage • Environment • Read/Write Cycle • Substrate ISSUES AFFECTING TAG LIFE: CONSTRAINTS: • Maxwell’s Equations: • Physical Constraints: • Hardware material limitations • Design limitations • Static power consumption • Dynamic power degradation • Range or Frequency practicality/effectiveness • Antennae field or design • Packaging • Environmental Constraints: • Temperature • Moisture/Humidity • Backscatter • Multiple tag • Noise • Fundamental Constraints: ACTIVE V/S PASSIVE TAGS: Active: Tags that contain a battery and their life cycle depends on the battery and its use Passive: They receive power externally and have limited processor performance *Part 1: Active And Passive Rfid: Two Distinct, But Complementary, Technologies For Real-time Supply Chain Visibility. Savi Technologies PASSIVE PASSIVEACTIVE SUPPLY CHAIN Manufacturers/ Suppliers Transportation/ Supply/ Theater Depots/TDCs POEs/PODsDistribution Centers/Depots Customers COMMON RFID APPLICATIONS: • Conversion charge electric field relationship • Result of magnetic flux due to non-existence of magnetic mono pole • Temporary change in electromagnetic field due to change in electric or magnetic field to form a self-propagating wave and speed within a medium Paine, Richard.
