SB QST @ ARL $ARLB013 ARLB013 FCC okays RF identification tags at 433.5 to 434.5 MHz ZCZC AG13 QST de W1AW ARRL Bulletin 13 ARLB013 From ARRL Headquarters Newington CT April 16, 2004 To all radio amateurs SB QST ARL ARLB013 ARLB013 FCC okays RF identification tags at 433.5 to 434.5 MHz The FCC has adopted a somewhat limited proposal to permit deployment of RF Identification (RFID) tags on the 70-cm band at much greater duty cycles than current Part 15 rules permit for such devices. Among other applications, RFID tags are used to track shipments and packing containers. A Third Report and Order (R & O) in ET Docket 01-278--approved April 15 but not yet released--follows a 2000 petition by SAVI Technology to revise FCC Part 15 rules to accommodate such devices in the vicinity of 433 MHz. The ARRL has consistently opposed the proposal, but the FCC just as unfailingly has gone along with it. FCC Office of Engineering and Technology (OET) Chief Ed Thomas said RFIDs provide important public benefits. "This device is designed to increase homeland security at ports, rail yards and warehouses," Thomas told the FCC open meeting. "It will foster the development of more powerful and advanced RFID systems that can identify the contents of shipping containers and determine whether tampering has occurred during shipment." Thomas said the devices also would increase efficiency in shipping operations and inventory control. In requesting Commission adoption, OET's Hugh van Tuyl provided the broad strokes of the Part 15 rule changes, which, he said, would apply specifically to shipping containers "in commercial and industrial areas." In certain cases, he asserted, current Part 15 requirements aimed at preventing interference to licensed services "may unnecessarily constrain the operational range of RFID systems as well as the speed and quantity of data that can be transmitted." The Third R & O would increase the maximum radiated field strength permitted for such devices as well as the maximum permissible duty cycle--from one second to one minute. The longer duty cycle would allow an RFID to transmit the contents of an entire shipping container, van Tuyl said. "We therefore believe there will be no significant increase in the potential for interference to authorized services," he concluded. The Third R & O reflects certain accommodations to the National Telecommunications and Information Administration (NTIA), which expressed "grave concerns" about the proposal in 2002. The R & O limits the operating band for such RFID tags to 433.5 to 434.5 MHz, instead of the 425 to 435 MHz SAVI originally asked for. It further prohibits operation of RFID tag systems within 40 km (about 25 miles) of five government radar sites. Manufacturers of 433 MHz RFID systems would have to register the locations of their system base stations to aid in interference resolution. Since SAVI first approached the FCC in 2000, ARRL has maintained that the RFID tags the company proposed would represent a significant source of potential interference to sensitive receivers and be incompatible with ongoing requirements of incumbent services. More than 130 amateurs filed comments in opposition to SAVI Technology's RFID tags proposal, and most supported the ARRL's position that the proposed rules were flawed and should not be adopted.
