Description: ThingMagic is shipping a Linux-powered RFID reader-based on a software-defined radio (SDR). The company says the Mercury4 can read any RFID tag format, including those not yet invented, and can be adapted to meet regional regulations. Additionally, it can read 266 million tag-instructions per second.
The Device uses a software-defined radio (SDR) to read RFID tags. The SDR is based on a Texas Instruments DSP chip running a proprietary RFID stack called 'MercuryOS'. According to ThingMagic, the Mercury4 reads all variants of EPC Class 1 and 0, including the new "rewriteable" Class 0 tag, as well as ISO 18000-6B and UCODE EPC 1.19. The unit's digital signal-processing software can be updated as needed to support additional RFID radio protocols as they emerge, such as EPC Generation 2 and ISO 18000-6A, the company says.
SDR also enables Mercury4 to support multiple frequencies, and regional regulatory variations, ThingMagic said. The first release of Mercury4 supports North American UHF regulations, but subsequent versions will support HF, European UHF, and Japanese UHF options.
