The size of a tag also depends on its area of use.
Rfid frequency range table.
Often used for vehicle identification.
Initially rfid tags were.
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.
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.
High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content.
6 765 6.
High frequency hf rfid 13 56 mhz.
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.
Frequency specific details 125 khz.
It can range from less than a millimeter.
Rfid range is fundamental.
To stay informed and take advantage of all of the unique resources rfid journal offers.
Rain rfid is a good solution when trying to track multiple products at one time such as large boxes full of product that is passing through a space or a cabinet full of inventory.
Typical hf rfid applications include tracking library books patient flow tracking and transit tickets.
Ultra high freqency uhf rfid 433 mhz 900 915 mhz.
If you re planning to use rfid you need to know what distance it will work over.
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.
Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.

Low frequency lf rfid 125 khz 134 khz.
Ultra high frequency rfid technology also known as rain has an extremely high read range compared to both lf and hf rfid tags.
Low frequency lf passive rfid tags.
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 band spectrum allocations.
Sometimes referred to as lowfid.
Active passive and semiactive.
These frequencies can be used globally without a license.
