Turn performance limitations into Competitive Advantage.


The Pioneers of UHF RFID: The Aerospace Industry
Published on by

Retail RFID seems to get the most limelight in the RFID industry at the moment. And that is not surprising because of its huge tag volumes and growth rates. But there are many other industries that are benefiting from RFID use as well. One of my personal favorites is the aerospace industry. To serve this industry, an ecosystem of RFID technology providers has emerged. In addition, the ecosystem has generated business opportunities for the supporting industry.

National UHF RFID Standards and RFID Performance
Published on by

ISO 18000-63 (6C, EPC Class 1 Gen 2) has been by far the most used UHF RFID standard for several years. There have been some competing standards such as Tagidu, IP-X (tag-talks-only) and ISO18000-62 (6B), but they are nowadays rarely used in new applications. However, new RFID standards still emerge: for example in Brazil, SINIAV has created a protocol aimed for vehicle tracking applications, and in China, a new UHF standard, GB/T29768-2013 has been recently published.

There are several chip and tag manufacturers working with these new standards. Why do these national RFID standards exist? And what does it mean for performance testing?

The Convergence of UHF RFID and NFC
Published on by

I saw my first combined UHF RFID-NFC apparel label at a trade show several years ago. I remember wondering what the reason for this combination was. After all, UHF RFID is primarily used in the business-to-business world of retail: supply chains, inventories, point-of-sale, etc. NFC on the other hand is used in the business-to-consumer interface: in retail, primarily brand enhancement. Could there be a reason to combine these two technologies?

Tagged-Item Grading Helps Retail UHF RFID Projects
Published on by

Retail and the retail supply chain are among the biggest users of UHF RFID technology. However, retail RFID projects are not the most simple ones. Items in retail come in all shapes, sizes and materials. They are shipped in different boxes, and stored and displayed on all kinds of racks, shelves and tables. Also different readers are used in different applications: logistics tracking, inventory count, RFID EAS, POS, and so on. I have been involved in a number of retail RFID projects, and I have seen how complicated the performance optimization can be.

GS1 Tagged-Item Performance Protocol (TIPP) was developed to help retail RFID by making buying and selling tags easier. But what do the TIPP guidelines mean, and what kind of testing is required?

How to Improve Efficiency of the R&D Team in UHF Tag Design
Published on by

Being responsible for sales of RFID performance measurement solutions, I’ve had the privilege of meeting with several companies and their design professionals around the world using very different methods for measuring UHF tag performance. Which is the best method then? I’d say it depends on your requirements – for a single basic measurement you may use various methods and even a simple method can be sufficient. However, if you are looking for a way to improve the throughput and efficiency of your R&D team in tag design the differences in methods are huge. So, where does the efficiency come from?

Why UHF RFID Tag Developers Should Use Wide Band Performance Testing
Published on by

RFID reader frequencies are controlled by governments and limited to narrow frequency bands that vary around the world. When the performance of an UHF tag is evaluated, focusing only on the narrow reader frequency bands is misleading. I have seen in several RFID projects, how the tag performance in field conditions is different from what is expected, leading to delayed projects and expensive re-planning. Testing in a wide frequency band is needed to get the correct information about and good visibility into UHF RFID tag performance. Read more about wide band testing and what it reveals from UHF RFID tag performance!

Is Now the Time for Passive RFID Sensing?
Published on by

One of the hot topics at this year’s RFID Journal Live! trade show in San Diego was passive RFID sensing. The show featured several new sensor products from companies like RF Micron, Smartrac, Phase IV Engineering, Farsens, and many others. But what is passive RFID sensing all about? And should you already be working with it?
