"This paper contains RF radiated emission and susceptibility data from passive Radio Frequency Identification (RFID) tags and readers operating at 13.56 MHz@ 915 MHz@ and 2.45 GHz. Laboratory test procedures incorporated the methods of RTCA DO-160D (test procedures for aviation electrical/electronic equipment) and DO-233 (test procedures for consumer portable electronic devices (PEDs)). Only one commercially available system was evaluated per established operating frequencies. Purpose The purpose of this paper is to record the RF radiated emissions and susceptibility from selected passive RFID systems operating at 13.56 MHz@ 915 MHz@ and 2.45 GHz. The emissions data (intentional and spurious) includes operation with both ""good"" and damaged tags. In addition@ RF radiated susceptibility tests were performed to determine functionality and inadvertent operation. These tests are limited in scope to the RF radiated emissions of PEDs tested in a controlled laboratory environment per the requirements of RTCA DO-160D@ RTCA DO-233@ and an airplane manufacturer's limit. This paper: ? identifies test units@ ?describes how the tests were conducted@ ? identifies support equipment and instrumentation@ ? includes test data@ and ? provides results."
