Rfid Tag Frequency Range

Ultra high frequency uhf much of the crossover or comparison between rfid and nfc concerns uhf rather than lf rfid tags.

Rfid tag frequency range.

An rfid tag consists of a tiny radio transponder. If you re planning to use rfid you need to know what distance it will work over. The frequency range along with other factors strongly determines the read range attachment materials and application options. 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.

High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content. Rfid range is fundamental. Low frequency lf passive rfid tags. Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects.

A radio receiver and transmitter. Low frequency lf rfid 125 khz 134 khz. When triggered by an electromagnetic interrogation pulse from a nearby rfid reader device the tag transmits digital data usually an identifying inventory number back to the reader. 1 pet and ranch animal identification.

High frequency rfid or hf systems. Rfid radio frequency identification is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object animal or person. Passive rfid tags have a more limited read range up to around 20m. Gao offers a large selection of rfid tags or transponders using different radio frequencies including active 2 45 ghz active 433 mhz ultra high frequency uhf 865 868 or 902 928 high frequency 13 56 mhz and low frequencies 125 khz and 134 khz that can be read by compatible rfid readers.

Each frequency has its unique benefits that provide customers a way to track assets in even the. Frequency specific details 125 khz. However the range of the low frequency range is limited to a few centimeters. Typical rfid applications using low frequency include access control and tagging of animals.

Typical hf rfid applications include tracking library books patient flow tracking and transit tickets. There are three main frequencies within which passive rfid tags operate. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter. 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.

Passive uhf tags in the frequency band 856 960 mhz are commonly used for asset tracking and inventory management. High frequency hf rfid 13 56 mhz.
