The electrification . is an ongoing technical paradigm shift in the auto industry. In this change, wireless power transmission (WPT) for electrical vehicle (EV) charging is a new enabling feature to wirelessly transfer power. However, its potential impact on other systems has not been investigated in depth. As aggravating circumstance, the frequencies for WPT-EV are also used by radio communication systems or services. Since WPT-EV is a new technology, there is a lot of work going on in the world in evolving the technology itself, but also in investigating interference in other systems and setting emission limits. There is, for example, a working group within the ITU-R that is examining the possible impact of WPT-EV on the radio communication services operating in the same or adjacent frequencies. There are several proposed frequency bands for WPT-EV with different characteristics.

This article addresses . the situation when you believe that all EMC aspects are under control since you have applied regular EMC standards the way you normally do – and then you get surprised by finding that you have electromagnetic interference (EMI) in the field operation, causing troubles for your customers. And even worse: your customers get the surprise first before you know anything, leaving you in the hot spot of explaining why this is happening.

Offprint from strategic outlook 8 . . Many of today’s vital societal functions rely on electronic control systems and wireless communication systems, such as GPS, mobile phones, and Wi-Fi. Cyberattacks with malicious code have become frequent, but since wireless communication systems and unprotected electronics can also be sensitive to electromagnetic (EM) threats, such as jammers and microwave weapons, intentional EM interference constitutes a tangible threat to civil defence capabilities and their potential to support military defence. It is therefore important that EM threats are considered in the risk and vulnerability analyses that authorities, municipalities, county councils, regions, and private enterprises with operations within civil defence are obliged to perform on their undertakings, especially concerning operative capability during a heightened state of alert.

The rapid increase . of wireless systems in safety- and security applications gives a need for automatic monitoring of electromagnetic interference in the vicinity of critical applications. Depending on the actual application of the wireless service, such monitoring might for instance be motivated for safety or security reasons. For efficiency reasons, such automatic monitoring techniques also need to be both cost efficient and relatively easy to use for the operator. The latter requires decision support in terms of methods for automatic analyses and classification of the collected interference data. In this article, the possibility of using Artificial Intelligence for these needs is discussed and exemplified.

The development within . the next generation of mobile technologies is going on for 5G. At the same time, research has already started for the future 6G. This research is in its initial stages and no agreements about key technical parameters and standards have yet been done. However, some suggestions on general principals and goals have been published from different actors. It is therefore interesting to see how these visions will affect the area of Electromagnetic Compatibility (EMC) in a larger sense.

The use of wireless applications . is continuously increasing in the society. Together with the overall increased use of electronics in general, the total electromagnetic environment is increasing around wireless systems. The effect of interference does not always appear as interruption in communication, but can appear as more or less gradually performance degradation for the user. In this article, some of these interference consequences are discussed and examplified.

Wireless connectivity . in cars is becoming more and more important. The functionality of the cars depends on a reliable wireless communication, e.g., for safety systems, infotainment, traffic warnings and updates of software and maps. To ensure that the desired and required wireless communication is achieved, extensive testing needs to be performed. Today a lot of the testing is done with drive-tests out in the field. However, this is both expensive and can only be done late in the development process, which makes it hard to modify the product.
