Rfid Frequency Range

Typical hf rfid applications include tracking library books patient flow tracking and transit tickets. High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content. 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.

Importance Of High Frequency Rfid Reader Rfid Frequencies Readers

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.

Rfid frequency range.

Rfid range is fundamental. The rfid range limit changes for each technology. 125 134 khz low frequency lf an extremely long wavelength with usually a short read range of about 1 10 centimeters. Rfid distance range depends on interferance and wave length.

Our active rfid range is 1km but passive rfid range is generally under 12m. An rfid tag consists of a tiny radio transponder. The frequency range along with other factors strongly determines the read range attachment materials and application options. There are three main frequencies within which passive rfid tags operate.

A radio receiver and transmitter. If you re planning to use rfid you need to know what distance it will work over. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter. Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects.

Each rfid frequency range is different. 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.
