Rfid Frequency Range

Our active rfid range is 1km but passive rfid range is generally under 12m.

Rfid frequency range.

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. The frequency range along with other factors strongly determines the read range attachment materials and application options. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter. There are three main frequencies within which passive rfid tags operate.

Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. Rfid range is fundamental. The rfid range limit changes for each technology. If you re planning to use rfid you need to know what distance it will work over.

An rfid tag consists of a tiny radio transponder. 125 134 khz low frequency lf an extremely long wavelength with usually a short read range of about 1 10 centimeters. High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content. A radio receiver and transmitter.

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. 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.
