RFID Tag Comparison Guide: Understanding Broadband Technology

RFID technology is maturing and presenting an array of options for unlocking new business value.

Ten years ago RFID solutions were limited by short read distances and high costs. The advent of passive UHF RFID and the EPC Class 1 Gen 2 protocol shifted the paradigm for users, opening up portal based solutions and global interoperability.

Three years ago Omni-ID expanded the reach of passive UHF by enabling real world solutions for applications that require tags to work on and around metal. Today on-metal tag technology has moved on yet further with an extensive range of different tag shapes, sizes and read distances available to meet the diverse needs of many.

One of the significant milestones of this technical innovation includes the launch of the world’s first truly global on metal passive UHF RFID tags.

This Poses the Question : Regional or Global?

To address this issue Omni-ID has developed an RFID Broadband Comparison white paper to address the following issues surrounding an RFID implementation:

• Will a small scale pilot with a regional tag be sufficient for the life of the asset?

• Is the geographic requirement the only factor in selecting global or regional – or is RF performance equally critical?

.

Regionally tuned tags have a characteristic high peak which affords long read distance over a limited frequency range. Conversely, global tags afford less peak read range but cover the full global 860-960MHz UHF RFID spectrum. Global tags therefore support all geographies in one tag, with a relatively similar performance across all regions.

Plotted on a graph the two responses look very different.
