EETE: How could it look from a technical perspective?
Steffen: Such devices are currently measured with a robotic arm that moves along the antenna beam. That is very time consuming. You can of course pack a large number of sensors into a test chamber, but that is no less expensive. If you have a spherical test setup, you of course need the same number of receivers as sensors. Plus there are many challenges in production, development and research. In the research phase there is no time pressure when taking measurements so you might be able to afford a robotic arm, but it's a different story in production.
EETE: In addition to 5G, one of the most prominent current trends in radiocommunications is the Internet of Things (IoT), which frequently runs via wireless connections and will require new wireless communications standards. How does this impact your business? Does it open up new business opportunities for you?
Steffen: Considering that there are more machines than people on this planet, IoT should actually boost our business. However, the modules that are to be used for this are often based on technologies that are already available. GSM, for example, is still very widespread. IoT applications
