| Popis: | This paper describes an intial study of the suscepti-bility to EMI of the wireless technologies which are or will be used in Intelligent Transportation Systems (ITS). In recent literature reliability comparisons between the two newest Radio Access Technologies (RATs) IEEE802.11bd and NR V2X are starting to appear. Yet none of them consider single/multiple frequency EMI as a possible interference despite the fact that these can and will appear in reality. In this paper two simulation methods and a real-life test method, in a reverberation chamber, are proposed to evaluate the reliability of the RATs under these interferences. Single-frequency CW interference evaluation is possible for a limited number of combinations using simulations, but multi-frequency CW simulations are nearly impossible to evaluate due to the large amount of possible combinations. Solutions are proposed to use a smaller test set of combinations. Evaluation of the RATs using simulations can be very useful, but will never reveal the full story how the RAT will react to interference. Therefore, a real-life test method in a reverberation room, or MIMO Antenna measurement system, is proposed trying to cover the full RAT protocol for a similar set of test combinations. |
