Rfid Frequency Range

An rfid tag consists of a tiny radio transponder.

Rfid frequency range.

Rfid range is fundamental. If you re planning to use rfid you need to know what distance it will work over. The rfid range limit changes for each technology. 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. 125 134 khz low frequency lf an extremely long wavelength with usually a short read range of about 1 10 centimeters. Our active rfid range is 1km but passive rfid range is generally under 12m. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.

The frequency range along with other factors strongly determines the read range attachment materials and application options. A radio receiver and transmitter. High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content. There are three main frequencies within which passive rfid tags operate.

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. Typical hf rfid applications include tracking library books patient flow tracking and transit tickets.
