Rfid Frequency Range

The frequency range along with other factors strongly determines the read range attachment materials and application options.

Rfid frequency range.

A radio receiver and transmitter. 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. 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.

There are three main frequencies within which passive rfid tags operate. Rfid distance range depends on interferance and wave length. 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. Each rfid frequency range is different.

Typical hf rfid applications include tracking library books patient flow tracking and transit tickets. Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. 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 range is fundamental.

The rfid range limit changes for each technology. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.
