RFID frequency ranges

1. The RFID frequency spectrum

RFID is considered as a non specific short range device. It can use frequency bands without a license. Nevertheless, RFID has to be compliant with local regulations (ETSI, FCC etc.)

oLF : 125 kHz - 134,2 kHz : low frequencies,

oHF : 13.56 MHz : high frequencies,

oUHF : 860 MHz - 960 MHz : ultra high frequencies,

oSHF : 2.45 GHz : super high...

Using the memory of the RFID chip

As seen with the unique identifier, information can be stored in the RFID chip's memory. Due to the cost of tags and the communication throughput permitted by most standards, RFID chip memories are rarely larger than ten kilobits. 

This is a long way off the storage capacity currently offered by the smallest...

1. The components of a RFID system

RFID Interrogator: These devices are radiofrequency (RF) emitters which activate the TAG passing near the antenna in order to supply the batteryless tag and send commands to these tags. A simple command consists of asking the tag its unique identifier for an inventory purpose. The frequencies used by RFID interrogators depend on the application and performance in terms of read range and/or...

Features of RFID tags

RFID SAW tags (Surface Acoustic Wave) do not have integrated circuits.

Today they only represent a small part of the market ( a few %).

They are read-only transponders and do not include embedded energy. They are...

Introduction to the RFID

1. Definition of RFID

For many of us, using a key to start a car, a card to access a building or room, using ski lifts on a winter sports holiday and validating a bus or underground ticket have become part of our daily routine. Without always realising it, we use automatic data capture technology that relies on radio-frequency electromagnetic fields. This technology is...
