Manuel Mielke discovered his passion for radio receivers while sitting in a Vodafone drive test van for several months, running network scans with scanners from Rohde & Schwarz. This was during his studies at the University of Applied Sciences in Regensburg, Germany. Today – an electrical engineering degree with a major in wireless communications and a stint at antenna specialist Kathrein later – Manuel finds himself “driving” the R&S scanners: as Product Manager Drive Test Scanners, he defines and shapes their specifications to help customers introduce new radio network technologies and features quickly and efficiently.

Electromagnetic field measurements in 5G: Overview and concepts (part 1)

What is different about 5G NR from a technology perspective? In layer 1, it is the heavy use of beamforming and frequencies above 3 GHz. Beamforming is used to overcome the increased path loss, especially at 3 GHz and above. However, beamforming and frequencies above 3 GHz have raised a large number of discussions among the population, especially about electromagnetic…
