Savi, DoD Contract Brings Cellular Connectivity, Mobility to Asset Management
The U.S. Department of Defense has signed its latest RFID-IV contract with Savi as the sole provider for updated technology, including hybrid RFID and cellular tags, lighter infrastructure kits and interrogation capability for RFID transponders when readers are unavailable.
Jun 18, 2018—
The U.S. Department of Defense (DoD) has signed a one-year extension to the fourth contract in a series—RFID-1, -II, -III and -IV—to improve wireless monitoring capabilities of assets in transit, storage and use around the world. The latest contract, with a $102 million ceiling during a five-year period, is intended to increase the flexibility and capabilities of its wireless technology systems to track assets in transit and in the field.
The system's sole provider is supply chain solutions firm Savi Technology. The extension contract (#W52P1J-14-D-0014) extends through April 2019 and dictates that Savi provide its RFID-based hardware and middleware to the DoD and other agencies.
Since 2013, Savi has provided approximately 95 percent of the DoD's RFID-related contracts, totaling $800 million (see U.S. DoD Reaffirms Commitment to Savi as Sole RFID-IV Provider). The contract extension, Johnston says, is designed to take advantage of improvements in technology, as well as enable better tracking in remote locations where it's impractical to install permanent RFID technology infrastructure. As part of the contract, Savi will also provide training and professional services.
"The DoD uses Savi's technology to power the world's largest and most complex supply chain," Johnston states. "Our transponders are placed on every container and pallet that is shipped into and out of the international area of responsibility," while the company's readers capture the tag data and transmits it to the DoD's dedicated network, known as the RF-ITV system, which feeds into multiple other logistics command and control systems.
At many locations, military personnel currently set up a temporary reader portal where tagged items flow through a specific area, so that goods in transit—or that are being received or shipped—can be captured. The portals come in kits, with the intention of being set up at sites anywhere around the world, to capture data and then forward it to the RF-ITV network. Savi's kits consist of a ruggedized laptop, a handheld RFID reader, a fixed reader (using active 433 MHz transmissions compliant with the ISO 18000-7 standard) and antennas, as well as an iridium modem with a satellite and cellular connection.
The DoD or some other agency then attaches Savi active RFID transponders to assets. As each tagged item approaches or passes through a specific gateway, within a distance of about 300 feet, the gateway reader wakes it up, after which is transmits its unique ID number, which is linked in the agency's software to a particular asset. "Our portable deployment kits allow for rapid deployment of logistics in transit visibility capability," Johnston explains, "by providing a complete system where infrastructure doesn't exist."
One shortcoming of this solution is that tags can only be captured when they come within range of a reader. However, the new version of Savi's tags can provide cellular transmissions as well. Savi also makes low-cost cellular transmitters without RFID functionality, for scenarios when only cell-based data is required.
