RFID Helps Cordes & Simon Document Shipments
The German logistics provider is using a system that integrates bar codes, video surveillance and RFID to track the locations and movements of packages within its warehouse.
Aug 24, 2007—Logistics provider Cordes & Simon (COSI), part of German transport network group System Alliance, has installed a tracking system that integrates bar codes, video surveillance and RFID to quickly locate a package while it's still in the company's warehouse or call up recorded images of it after it has left. The company installed the system during the construction of its newest warehouse in Villingen-Schwenningen, in southern Germany, which opened in May, one of six warehouses the company operates.
Cordes & Simon needed a system that would help the company automatically locate a missing package and document when a shipment arrived and left the warehouse. The company met with ESEG E.U.R.O. Security Group, which provided video recorders and systems integration, while Ubisense provided RFID technology. They spent about six weeks getting the system fully deployed, according to says Ubisense's sales and marketing vice president, Terry Phebey.
The warehouse has 22 Ubisense 7000 Sensor readers, deployed at a height of 5 meters throughout the warehouse, for receiving the transmissions from a distance up to 160 meters (500 feet). They measure the elevation and azimuth (angle) of the transmission from the tags as well as the time distance of arrival (TDOA) of transmission between several readers, thereby determining the location of each tag within 15 centimeters. Transmissions are received and then sent to the system server about three times a second via an LAN cable.
