One consequence of the pandemic lockdown . due to Covid-19 has in some cases been a significant decrease of traffic volumes from vehicles. At some borders, the decrease of personal car traffic was significantly reduced during the lockdowns in the spring of 2020. Since vehicles can contribute to the background electromagnetic interference environment, it is of interest to investigate if the pandemic lockdown has led to any observable differences in measured background electromagnetic interference levels. Measurements have been done in the civilian GPS-frequency band in the vicinity of the bridge over Öresund, between Sweden and Denmark. A significant reduced level of electromagnetic interference can be seen as a result of the lockdown in the spring of 2020. Furthermore, these measurement results indicate that passenger cars have the largest contribution to the interference in the GPS-band.

The ongoing technical development . towards increased densities of co-located electronic systems together with new unintentional interference sources requires analyses of considerable more complex interference environments than before. To handle such environments, dedicated analysis tools and methods are needed to handle larger amounts of electronic systems as well as measurement data from emission measurements. In this paper, some of these challenges are discussed and examples of possible analysis methods are shown.

Abstract — . The technical development towards the full vision of the Internet of Things (ioT) is expected to reach it´s full potential by the coming 5G wireless technologies. This will open up for so called massive IoT characterized by co-location densities in the order of 200000 devices per km2. This development will affect the area of Electromagnetic Compatibility (EMC) in a number of ways and may even be the most challenging issue for the EMC area since it was born for over 100 years ago. In this paper, some of these new challenges are highlighted and discussed. Furthermore, numerical results from some dense co-location scenarios are presented to show examples of interference challenges to be handled.

Introduction .  The European Union (EU) Horizon2020 project Standardisation of Global Navigation Satellite System (GNSS) Threat Reporting and Receiver Testing through International Knowledge Exchange, Experimentation and Exploitation (STRIKE3) is a new European initiative to support the increasing use of GNSS within safety, security, governmental and regulated applications. One of the objectives of STRIKE3 is the deployment and operation of an international GNSS interference monitoring network to capture the scale and dynamics of the problem, and to work with international GNSS partners to develop, negotiate, promote and implement standards for threat reporting and receiver testing. Both standards are missing across all civil application domains and are considered a barrier to the wider adoption and success of GNSS in the higher value markets.

The use of wireless . technology is increasing rapidly in critical societal functions such as energy production, transport, logistics, banking and financial systems, and industrial and security applications – this despite the fact that civilian consumer wireless technology in general is very sensitive to both unintentional and intentional interference signals. Therefore Electromagnetic Compatibility (EMC) issues are highly important to address. Hitherto only military actors have been able to utilize or take advantage of this sensitivity effectively, but this ability is now spreading to civilian actors, thanks to sophisticated jamming equipment which is now sold openly and inexpensively via the Internet.

In the past . 30 years, more and more devices have started using the US Global Positioning System (GPS) and related global navigation satellite systems (GNSS). This trend contributed to Europe’s decision to create its own system, Galileo, and this began offering initial services at the end of 2016. As well as Galileo, the Indian Regional Navigation Satellite System (IRNSS) now has a full constellation, and there are rapid developments in several commercial industries. So, 2017 promises to be an interesting year for developments in GNSS. Here are a few of the industry changes we expect to see this year…
