Comparison of the typical rfid read range according to frequency band passive tags while table 1 compares the read range of passive tags note that there are actually three rfid tag types.
Rfid frequency range table.
Rfid range is fundamental.
1 pet and ranch animal identification.
If you re planning to use rfid you need to know what distance it will work over.
Rfid frequency band spectrum allocations.
Ultra high frequency uhf is the itu designation for radio frequencies in the range between 300 megahertz mhz and 3 gigahertz ghz also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter one decimeter radio waves with frequencies above the uhf band fall into the super high frequency shf or microwave frequency range.
Read distance of 30 cm 1 foot or less usually 10 cm 4 inches unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal.
Back to table of contents the first rfid application was the identification friend or foe system iff wiki rfid wizard wars.
Active passive and semiactive.
Ultra high freqency uhf rfid 433 mhz 900 915 mhz.
Typical hf rfid applications include tracking library books patient flow tracking and transit tickets.
Low frequency lf rfid 125 khz 134 khz.
125 134 2 khz and 140 148 5 khz.
It can range from less than a millimeter.
Sometimes referred to as lowfid.
The size of a tag also depends on its area of use.
Up to 1 2 metre.
Frequency specific details 125 khz.
High frequency hf rfid 13 56 mhz.
Only rfid journal provides you with the latest insights into what s happening with the technology and standards and inside the operations of leading early adopters across all industries and around the world.
These frequencies can be used globally without a license.
This depends on rf transmit power the receive sensitivity the surroundings how much water is present the orientation of the tag frequency of operation and the care that s gone into designing the products planning and installing the system.
Ultra high frequency rfid technology also known as rain has an extremely high read range compared to both lf and hf rfid tags.
Initially rfid tags were.
To stay informed and take advantage of all of the unique resources rfid journal offers.
Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.

This paper provides a survey on radio frequency identification rfid technology.
High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content.
