Active Rfid Frequency Range

An rfid tag consists of a tiny radio transponder.

Active rfid frequency range.

A radio receiver and transmitter. Our active rfid range is 1km but passive rfid range is generally under 12m. Our 433 mhz readers can read battery powered rfid tags from a long range from 20m 100m and have high speed reading capabilities. 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.

Low frequency lf rfid 125 khz 134 khz. Rfid distance range depends on interferance and wave length. The prices of active rfid tags range anywhere from 20 to 100 depending on the tag s ability to withstand harsh conditions and other key functional features of the tag. High frequency hf rfid 13 56 mhz.

Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. We know that the radio frequency range is from 3 khz to 300 ghz but the rfid generally uses radio frequencies in ranges within the radio frequency rf band categorized as below. Rfid range is fundamental. 1 pet and ranch animal identification.

Other technologies further information in other articles of this blog make it possible to extend this distance to up to one kilometer. In general active tags are used on large objects such as rail cars big reusable containers and other assets that need to be tracked over long distances. 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. Given the required investment of an active rfid system active tags are usually reserved for tracking high worth assets or for items where accurate location tracking is.

Litum iot experts can help design and deliver such a system that suits your needs with sub meter accuracy no matter how big the space. Passive rfid the second case concerns passive rfid. If you re planning to use rfid you need to know what distance it will work over. Super high frequency shf requires the use of active rfid tags.

By interrogating active tags that continuously broadcast a signal active 4 33 mhz readers are the ideal solution for real time location systems. Frequency range used by rfid technology. A modern long range active radio frequency identification system rfid is the best way to make this happen. Its range is in between 30 khz to 500 khz but the exact frequency used by it is 125 khz.

The rfid range limit changes for each technology. Unlike active tags passive tags do not include any embedded power source.
