RFID Breaks Speed Records for Tolling Solution

Kathrein and Tönnjes used a German racetrack to test and demonstrate the effectiveness of UHF RFID tag reads at speeds greater than 220 kilometers per hour, utilizing Kathrein's readers and software and Tönnjes' IDePLATE tags.

Technology companies Kathrein Solutions and Tönnjes have completed a test of Tönnjes' IDePLATE and IDeSTIX tags with Kathrein's reader and software platform, and have captured tag reads at speeds of more than 220 kilometers per hour. They did so for an audience of existing and prospective customers, in order to illustrate how effective the latest iteration of their technology is. The companies also demonstrated a new tag designed for motorcycle headlamps.

Kathrein Solutions is a German Internet of Things (IoT) company that provides RAIN RFID solutions. Tönnjes makes vehicle-identification solutions, including its IDePLATE license plates with integrated RFID tags, and its IDeStix adhesive tags that can be applied directly to a vehicle's windshield. While the companies are providing their passive UHF RFID-based technology for a handful of government agencies, they wanted to demonstrate what the system was capable of, so they scheduled a test at Germany's Sachsenring racetrack, in the city of Chemnitz, and invited potential customers. Approximately 90 guests from 30 countries watched the testing take place.

During the test, the partners operated vehicles in a variety of scenarios, tracking their movements using tags and readers designed for electronic vehicle registration systems and electronic toll collection. Each vehicle had an IDePLATE on the front and rear, as well as IDeSTIX tag on the windshield or motorcycle headlamp, and installed Kathrein's RRU4500 readers around the track. Read data was managed by Kathrein's CrossTalk software platform. "We've done testing before," says Thomas Brunner, Kathrein's head of IoT solutions business line, "but never invited customers to attend, so this was our opportunity to demonstrate the robustness of the system."

The testing consisted of heavy trucks, cars and motorcycles. As they circled the track, Kathrein reader antennas captured each tag's unique ID number and updated the software accordingly. They tested the tags in crowded environments, in which vehicles follow closely behind each other on the track, as well as on vehicles travelling at high speeds and on changing lanes. Moreover, they tested the newest product: the motorcycle headlamp tag.

Kathrein acquired NoFilis three years ago (see Kathrein Group Acquires NoFilis) and has since leveraged the automatic-identification software from that acquisition to offer solutions using its own UHF readers and antennas for the automotive, industrial, logistics, tolling and parking sectors. The company has been offering end-to-end solutions for roadside vehicle identification, or for outdoor access control at such locations as parking lots and garages. "One important market for us, with Tönnjes as partner," Brunner, "is vehicle identification for governments, while also providing a solution with a government transponder for tolling."

Traditionally, tolling companies have offered active 5.8 GHz transponders requiring a battery to transmit data, but Kathrein has moved into the market of providing passive RFID technology compliant with the ISO 18000-63C standard, with Tönnjes as its global partner for government-mandated electronic vehicle identification. Tönnjes' tags employ NXP Semiconductors' UCODE DNA chipset, which supports up to two 128-bit AES authentication keys. They are stored in the tag IC's internal memory and can be pre-programmed and locked. These cryptographic keys can be used either for tag authentication or for privacy protection.
