Two RFID companies have announced 433 MHz hardware that they claim is the first to comply with a relatively new open air-interface protocol—IEEE 802.15.4f-2012. Omni-ID’s new Power 415 tag integrates a passive EPC Gen 2 ultrahigh-frequency (UHF) inlay with an active 433 MHz transponder compliant with the IEEE standard, while Guard RFID Solutions’ Tag Reader Receiver (TRR) has been newly updated to interrogate active 433 MHz tags via the open standard. The two companies each independently tested the interoperability of the reader and the tag last month, and found that the products work well together. During testing, both firms employed Guard RFID’s AllGuard RTLS and Security software, while Omni-ID also used its own software to manage the collected read data. The 2012 release of the IEEE 802.15.4f standard provided potential users of 433 MHz active RFID tags with the option of building a system based on the open standard that could mix and match products from different vendors. This, however, requires that vendors release such technology using the standard. There are 2.4 GHz RFID readers and tags already available that comply with the IEEE 802.15.4f standard, as...
