Advances in RFID technology can help Army logistics managers more closely track equipment and supplies in transit.
As weapons, ammunition, supplies, and vehicles flow on the battlefield, the US military needs better material tracking methods. The Enterprise Information Systems Project Executive (PEO EIS) is working with partners and Transportation Command to collect the need for the next generation of operational visualization capabilities.
At the heart of today's transportation tracking is radio frequency identification (RFID), which allows logisticians to tag and track shipments. But RFID also has its limitations: it requires a lot of infrastructure and cannot be deployed around the world. With the widespread use of active RFID, RFID technology has taken a big step forward. Instead of manually scanning a single item, proactive RFID uses a fixed scanner to monitor the entire batch of supplies. However, active RFID is not an ideal solution. It includes a dome-shaped reader connected to the power supply and Ethernet. Each reader costs thousands of dollars, plus the wires and communication lines that connect these readers and the cost of maintenance, making it a large engineering investment. In addition, active RFID devices are not suitable for today's highly flexible expeditionary operations.
Satellite-readable RFID tags provide a solution because they can expand the military's coverage without additional costs. But the cost of using satellites is high.
Savi has proposed a new solution that will use widely available cellular signals as a new means of capturing and communicating with RFID information. In the past three or four years, Savi has conducted early experiments on cellular mobile RFID in Africa and has successfully used cellular technology. Switching to cellular technology is not complicated: you only need to add a cellular module to an existing RFID tag, and then programmatically cause the module to automatically report the location status to the military's operational visualization server. High-value items may be reported once an hour, while regular supplies can be set to be checked daily or every few days to save battery power in RFID tags. The location and status of the material can be viewed in more detail using a cellular system than a fixed checkpoint.
