An active RFID system can read tags from 1,500 feet away or more, as the tags broadcast a signal and the systems are designed for longer-range applications.
What is long range RFID reader?
These long range readers are used to interrogate active RFID tags that use the 2.45 GHz and 433 MHz frequencies. Most of the long range RFID readers have an omni-directional antenna which gives a good read range of up to 338 feet (100m), while some of them have an option to attach an external antenna.
Is RFID long range?
RFID is a contactless technology that can operate over a range from a few centimetres to several metres, using frequencies of 120 to 150 kHz (Low Frequency, or LF), 13.56 MHz (High Frequency, or HF) and 860 to 960 MHz (Ultra-High Frequency, or UHF).
How do I increase the range of my RFID reader?
- Antennas. Higher-gain antennas get more power from RFID readers compared to lower-gain antennas.
- Polarization. Polarization talks about the type of electromagnetic field the antenna produces.
- SOAP Method. SOAP stands for size, orientation, angle and placement.
- Reader Settings.
- Shorter Cables.
What is the maximum range of RFID?
Generally speaking RFID tag maximum read distances are as follows: 125 kHz. and 134.3 kHz. Low Frequency (LF) Passive RFID Tags -read distance of 30 cm (1 foot) or less - usually 10 cm (4 inches) unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal.
