RTLS Comparison: 802.11 vs. Time of Arrival (TOA)

Subject Matter Expert Rod Saunders talks about his experiences implementing 802.11 Wi-Fi and Time of Arrival (TOA) based real time location systems, including:

  • installation time
  • system accuracy
  • system accuracy
  • tag battery life and
  • total cost of ownership.

BAP RFID - Battery Assisted Passive RFID

Traditional Passive RFID Tags rely on gathering energy from the RFID Reader's signal to wake up the integrated circuit (IC) and provide the backscatter required for identification. BAP RFID tags contain their own integrated power source, which is most commonly a battery. It’s very important not to confuse BAP tags with Active RFID Tags. Active tags transmit a beacon at a defined interval. BAP tags do not transmit. The range is improved because no energy needs to be harvested from the reader to power the chip and all of the captured energy can be used for backscatter.

Why RFID Reader Sensitivity is Critical When Using BAP RFID Tags

Since our first BAP (Battery Assisted Passive) RFID benchmark tests in 2009, RFID Network engineers have received dozens of calls from people complaining that BAP tags perform no better than 20¢ passive labels. While they're both passive RFID, they are designed in very different ways. In nearly every situation, the problem is the RFID reader being used does not have high sensitivity. Obviously, some RFID readers perform better than others, but this is especially true when working with BAP tags. In this video, intended for our technical viewers, we talk with Dean Kawaguchi who sits on the ISO RFID committee to understand why reader sensitivity is critical when working with BAP tags.

EID Tags - Electronic Identification Ear Tags for Cattle Identification

Using RFID for Animals, Food and Farming will grow 307% from $1.17 billion in 2011 to $4.09 billion according to IDTechEx. CattleIdentification.org and The RFID Network have put together a comparison of EID (Electronic Identification Device) tags or RFID ear tags for use on cattle. We tested a variety of EID tags using both ISO 11784 and ISO 11785 and ISO/IEC 18000-6C / GS1 EPCglobal C1G2 standards.

ABS, NEMA and IP Ratings : About RFID Radio Frequency Identification

Do you know what ABS, NEMA and IP Ratings are? Do you know what IP-67 means?

A NEMA rated RFID Equipment box made of ABSAcrylonitrile butadiene styrene (ABS) is a thermoplastic used to make light, rigid, molded enclosures. One of the most common ABS products is Lego™ building blocks. There are RFID tags that are encased in ABS to improve impact resistance, toughness, and water/heat resistance. ABS products are typically given a NEMA or IP rating for durability.

NEMA (National Electrical Manufacturers Association) has established a range of standards for electrical equipment enclosures.

The IP (Ingress Protection or International Protection) Rating is defined in international standard IEC (International Electrotechnical Commission) 60529.

Both rating systems classify ...

Adhesives and RFID Tags : About RFID Radio Frequency Identification

Do you know the 3 different types of adhesives typically used by RFID tags and RFID labels and why they are important?

adhesives.jpgFor an RFID label, the cohesion breakage of the adhesive must be strong enough to keep the tag on the backing, but only until a person or label applicator removes it. Then parts of the adhesive remain on the back of the tag so that it can be affixed to an item, typically at room temperature.

Antennas : About RFID Radio Frequency Identification

What's the difference between a linearly polarized antenna and a circular polarized antenna? Here's the detailed explanation.

Unlike water waves, electromagnetic waves are not influenced by gravity, and the electric field can point in any direction in the plane perpendicular to the direction of propagation. Because human beings are gravitationally challenged, it is most common to orient linearly polarized antennas either vertically or horizontally. It is also possible for the direction of polarization to be time dependent. For example, the electric field can rotate around the axis of propagation as a function of time, without changing its magnitude, producing circularly polarized radiation
