BENEFITS OF BACKSCATTER TAGS OVER “ACTIVE” TRANSMITTER TAGS
• Lower cost, simpler circuitry
• Longer battery life
• Stealthier (safer in sensitive environments, e.g., airplane)
• No transmitter tags can be used worldwide due to licensing issues, spectral
pollution, etc.
TAG BLOCK DIAGRAM
The following diagram illustrates the design of the battery-powered backscatter
tag.
Applications for 2450 MHz Battery-powered Backscatter
Tag/Reader Systems
A variety of applications have already been identified that can benefit from the
use of battery-powered backscatter tags and readers, including the following:
• Long range identification
• Vehicle-asset tracking
• Supply chain automation
• Time temperature monitoring
• Tamper detection (safe/secure supply chain)
• Security/ access systems
• Sensor monitoring
• Immobilizer / beeper / LED (can control outputs)
• Passive tag data storage for hierarchical asset tracking systems
• Location capability has been proven
