The rfid range limit changes for each technology.
Active rfid frequency range.
If you re planning to use rfid you need to know what distance it will work over.
Unlike active tags passive tags do not include any embedded power source.
Its range is in between 30 khz to 500 khz but the exact frequency used by it is 125 khz.
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.
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.
1 pet and ranch animal identification.
High frequency hf rfid 13 56 mhz.
Our active rfid range is 1km but passive rfid range is generally under 12m.
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.
Rfid range is fundamental.
An rfid tag consists of a tiny radio transponder.
Super high frequency shf requires the use of active rfid tags.
A radio receiver and transmitter.
Active tags have a very long coverage range exceeding 500 m.
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.
Our 433 mhz readers can read battery powered rfid tags from a long range from 20m 100m and have high speed reading capabilities.
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.
Frequency range used by rfid technology.
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.
Rfid distance range depends on interferance and wave length.
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.
Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects.
Low frequency lf rfid 125 khz 134 khz.
