Electronic Vehicle Identification (EVI) tags are a perfect match to RAIN RFID (UHF RFID) technology. Once a vehicle is tagged, the possibility to identify the vehicle remotely enables a lot of applications and services. While the vehicle tagging is of high interest, it is not the easiest task. In the past few months I have worked with some vehicle tagging projects and learned that the application requires some special attention from technology providers.Read more →
Combine identification, sensors, low cost and years of life time together and you certainly end up with a disruptive mixture that is set to boil over in the near future. RAIN RFID sensors may not be a huge market just yet, but we can see many companies putting a lot of development effort on them. Read on to see an introduction to the six topologies that I’ve seen utilized so far.Read more →
What do you do if, one morning, a new light with some strange symbol is suddenly lit on your car’s dashboard? You probably pull over and start browsing the car owner manual. You may be a little worried. Did I do something wrong? Can I fix this myself or does the car need to be serviced? How long will I need to survive without my car? The same way your Tagformance, the RFID test system that you typically use every day, may have a problem you need to solve. You may already be an experienced user or maybe you have just recently started to work with the system. When a new error message pops up, or you get unexpected measurement result, it’s just like with your car. What’s wrong? Should I contact Voyantic Technical Support?Read more →
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?Read more →
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?Read more →
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.
