The Special International Committee on Radio Interference(abbreviated CISPR from the French name of the organization, Comitéinternational spécial des perturbations radioélectriques) is concerned withdeveloping norms for detecting, measuring and comparing electromagneticinterference in electric devices. CISPR’s principal task is at the higherend of the frequency range, from 9 kHz upwards, repairing standards thatoffer protection of radio reception from interference sources such aselectrical appliances of all types, the electricity supply system,industrial, scientific and electromedical RF, broadcasting receivers (soundand TV) and, increasingly, information technology equipment (ITE).

Abstract
The electromagnetic energy source used by wireless communication devices in a vehicle can cause electromagnetic compatibility problems with the electrical and electronic equipment on board. This work is focused on the radiated susceptibility (electromagnetic susceptibility [EMS]) issue and proposes a method for quantifying the electromagnetic influence of wireless radio frequency (RF) transmitters on board vehicles. The key to the analysis is the evaluation of the relation between the electrical field emitted by a typical Bluetooth device operating close to the automobile’s electrical and electronic systems and the field level specified by the electromagnetic compatibility (EMC) directive 2004/104/EC for radiated susceptibility tests. The chapter includes the model of a closed circuit structure emulating an automobile electric wire system and the simulation of its behaviour under electromagnetic fields’ action. According to this a physical structure is designed and implemented, which is used for laboratory tests. Finally, simulated and experimental results are compared and the conclusions obtained are discussed.
