What is the read range of UHF RFID tags?

Ultra-high frequency (UHF) RFID The UHF frequency band covers the range from 300 MHz to 3 GHz. RAIN RFID systems comply with the UHF Gen2 standard and use the 860 to 960 MHz band. While there is some variance in frequency from region to region, RAIN RFID systems in most countries operate between 900 and 915 MHz.

How far away can an RFID tag be read?

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.

What is the maximum range of the RFID module?

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.

What is UHF RFID tag?

A basic UHF RFID tag is comprised of an antenna and the IC. Antenna – A tag’s antenna is unique to that specific type of tag and its job is to receive RF waves, energize the IC, and then backscatter the modulated energy to the RFID antenna. Each IC type is unique, and there are only a handful of manufacturers.

How much does an RFID tag cost?

Generally speaking, active tags are $25 and up. Active tags with special protective housing, extra-long battery life or sensors can run $100 or more. A passive 96-bit EPC inlay (chip and antenna mounted on a substrate) costs from 7 to 15 U.S. cents.

Does RFID require line of sight?

No Need for Line of Sight – Unlike barcodes, RFID tags do not require line of sight scanning and can be read in bulk (e.g., by the pallet). RFID tags can also be read at much greater distances – up to 300 ft.

How long does a passive RFID tag last?

Depending on how often the tag transmits data, the battery can last five to ten years. Passive tags have no battery, so there is no such shelf life to the tag.

How long do passive RFID tags last?

What is the most common RFID frequency?


Frequency Bands Antenna
High Frequency (HF) 13.56 MHz Induction Coil flat 3-9 turns
Very High Frequency (VHF) 433 Mhz – Active Tags Internal Custom Design
Ultra High Frequency (UHF) 860 MHz – 960 MHz Single or Double Dipole
Microwave Frequency 2.45 GHz & 5.4 GHz Single Dipole

What are the two types of RFID tags?

Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).

  • Low-frequency (LF) RFID tags: 30 KHz to 300 KHz.
  • High-frequency (HF) RFID tags: 3 to 30 MHz.
  • Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz.
  • Active, passive and semi-passive RFID tags.

How much does a passive RFID tag cost?

The primary advantage of passive RFID systems is that tags are very inexpensive, ranging from $0.10 to $1.50 per tag. These tags also don’t require batteries, so they last for many years.

Is RFID installation free?

While the RFID stickers themselves are free of charge, motorists will be required to load a minimum amount upon installation.

What is the operating range of a RFID tag?

Far-range UHF RFID tags can read at ranges as far as 12 meters with a passive RFID tag, whereas active tags can achieve ranges of 100 meters or more. The operating frequency of UHF RFID tags ranges from 300 MHz to 3 GHz, and UHF tags are the most vulnerable to interference.

How are UHF tags different from other RFID tags?

UHF tags are serving a different set of applications compared to classic RFID tags. Ultra-High Frequency (UHF) tags, as the name conveys, operate at a higher frequency range to transmit data within a more extended range. These tags carry a few building blocks to serve the purpose of long-range requirements.

What are the challenges of a UHF RFID reader?

The main challenges involved with developing and operating a UHF RFID system reside in the reader and the passive tag, as outlined below. The most important tag limitation is the chip sensitivity threshold. This is the minimum amount of received RF energy that is needed in order to power the RFID chip.

Which is the best antenna for long range RFID?

When paired with our 2.45 GHz readers or 433 Mhz readers and matched with our RFID antennas, optimal gain can be attained, provided even longer reading distances. GAO RFID offers a variety of long range RFID tags with protocols that enable users to track large and high valuable assets across large areas and spaces.
