Migrating to the 5 GHz Wi-Fi Band Will Advance RTLS and M2M Communications
A crowded RF environment impacts the battery life of Wi-Fi devices significantly—and the first to be affected are those operating in the 2.4 GHz band.
RFID: The Early Years
Radio frequency identification has matured, and its benefits have been proved. Now, it’s time to put the technology in perspective.
What Are the Requirements for ATEX-Rated Passive Gen 2 UHF RFID Tags?
Do such tags pose any ignition hazard, and has testing been performed to determine whether they can be dangerous? —Daniel ——— Daniel, The ATEX Directive, which became mandatory in Europe in 2003, dictates that all electrical and mechanical equipment used near...How Can I Contain RFID Signals So They Do Not Interfere With Other Devices?
And how can I prevent the reading of tags that I don’t want interrogated? —Name withheld ——— Those are often two different issues. There are several ways in which to contain RFID signals. Some companies build Faraday cages, which are typically metal mesh...What Is the Fastest Acceptable or Reliable Response Time for a UHF Reader to Interrogate a Tag?
What would that time be, in seconds? —Name withheld ——— I am unsure what you mean by “fastest acceptable or reliable.” The EPC Gen 2 RFID protocol calls for tags to be read at a rate of 850 times per second under the Federal Communication...Battery Supplier Deploys RFID to Manage Product Inventory
A major automotive battery maker is using Seeonic’s SightWare-Seeniq system, installed on shelving, so that it can view whether its batteries need to be restocked at third-party locations, such as auto repair shops and parts dealers.
