Active Rfid Frequency Range

Active tags have a very long coverage range exceeding 500 m.

Active rfid frequency range.

The rfid range limit changes for each technology. Frequency range used by rfid technology. 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. Passive rfid the second case concerns passive rfid.

Active rfid systems typically operate in the ultra high frequency uhf band and offer a range of up to 100 m. 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. 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. 1 pet and ranch animal identification.

Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. A radio receiver and transmitter. 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. A modern long range active radio frequency identification system rfid is the best way to make this happen.

Other technologies further information in other articles of this blog make it possible to extend this distance to up to one kilometer. Low frequency lf rfid 125 khz 134 khz. Unlike active tags passive tags do not include any embedded power source. High frequency hf rfid 13 56 mhz.

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. Our active rfid range is 1km but passive rfid range is generally under 12m. Each rfid frequency range is different. Rfid distance range depends on interferance and wave length.

Super high frequency shf requires the use of active rfid tags. Our 433 mhz readers can read battery powered rfid tags from a long range from 20m 100m and have high speed reading capabilities. Its range is in between 30 khz to 500 khz but the exact frequency used by it is 125 khz. 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. By interrogating active tags that continuously broadcast a signal active 4 33 mhz readers are the ideal solution for real time location systems.
