Emulation des Funkkanals und des Transponders in UHF-Mautsystemen

SummaryUHF-RFID (ultra high frequency – radio frequency identification) systems have gained importance for road tolling applications. They allow for low-price and batteryless transponders but rise several technical problems. This article shows how these problems can be identified and solved by means of emulating the radio channel's and the transponder's behavior.ZusammenfassungFür Mautanwendungen werden vermehrt UHF-RFID(ultra high frequency – radio frequency identification)-Systeme eingesetzt. Neben den Vorzügen des kostengünstigen und batterielosen Transponders bringt ein solches System jedoch eine Vielzahl technischer Problemstellungen mit sich. Dieser Artikel zeigt, wie diese mittels Emulation des Funkkanals sowie des Transponders analysiert und gelöst werden können.
