GuardRFID Field-Trials Solar-Powered RTLS Solution for Hazardous Areas

GuardRFID, a provider of active RFID and real-time location system (RTLS) technologies for industrial environments, has announced that it has successfully completed field trials of its solar-powered and fully wireless RTLS solution. The system is suitable for deployment at remote locations, the company reports, or where power and/or connectivity may not be easily available.

The trial was conducted at a test yard of a major oil and gas exploration company in the West Texas Permian Basin in early December 2015. Since then, according to the company, the solar-powered system has exceeded performance goals that had been set at the beginning of the trial.

GuardRFID's active RFID technology is compliant with the IEEE 802.15.4 standard, the firm reports, and operates at 433 MHz—a frequency band suitable for global consumption and not constrained by local regulatory requirements. The entire trial used Wi-Fi communications for local connectivity within the yard, and a cellular uplink from the yard to one of GuardRFID's enterprise RTLS servers in Vancouver, Canada.

GuardRFID tags, intended for deployment in hazardous areas, are certified for use in the most explosive environments, designated as Zone 0 (IECEx/ATEX classification) or Class1/Div1 (UL/CSA classification). Several such tags, certified as being intrinsically safe devices, are available for placement on personnel, as well as on small or large equipment, GuardRFID reports. These tags operate within a system comprising GuardRFID's infrastructure devices (Industrial Tag Reader – EX, and Industrial Tag Exciter – EX) that also carry IECEx and UL/CSA certifications for use in hazardous environments.

"We have been deploying our RFID/RTLS technology in industrial environments for several years now, but this is the first time we have eliminated all the wiring from a system installation," said Dalibor Pokrajac, GuardRFID's CTO, in a prepared statement. "This six months trial, conducted in an environment which is a true representation of a remote industrial site that lacks electrical power and network connectivity, has truly demonstrated our system's robustness and versatility. This, combined with the highest hazardous area certifications our equipment carries, and the system's compatibility with worldwide regulatory requirements, further enhances GuardRFID's position as a dominant supplier of RTLS technology for large scale industrial enterprises that have a global footprint."
