How does read angle affect RFID read range?
The two are separated by some Z distance, and they never touch. In short, you’ll get the best range when you read the tag face-on – the steeper the read angle, the more the read range will decrease. Some RFID tags, such as the embeddable RFID wire tag, have a 360 degree read profile which mitigate the read angle concern.
What is the use of UHF in RFID?
The use of UHF technology spans many markets; including retail, healthcare, life science, pharmaceutical, anti-counterfeiting, transportation, and manufacturing. There are some things to consider when looking at RAIN RFID for your solution.
How to describe the orientation of a RFID tag?
Tag Orientation and Read Angle: In order to explain the tag orientation and read angle, picture an RFID tag lying flat on a stool. Then, picture an RFID antenna on the ceiling facing downward above the stool.
What’s the difference between rain and LF RFID?
Ultra-high frequency RFID technology, also known as RAIN, has an extremely high read range compared to both LF and HF RFID tags. RAIN RFID is a good solution when trying to track multiple products at one time, such as large boxes full of product that is passing through a space, or a cabinet full of inventory.
How much power do you need to transmit a RF signal?
An intensely focused RF transmission from far away might overpower a weaker local RF signal. You need to limit the power you transmit from the antenna and this depends on the type of antenna you use. Regulations in the USA limit the transmit power in the UHF band to 4Watts EIRP.
What’s the range of a low frequency RFID tag?
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.
What’s the maximum range for a skyrfid RFID tag?
There are no limits with SkyRFID! 13.56 MHz. High Frequency (HF) Passive RFID Tags Maximum read distance of 1.5 meters (4 foot 11 inches) – usually under 1 meter (3 feet) and you can use a single or multi port reader plus custom antennas to extend the read range to longer tag read distances or a wider RFID read zone.
