This paper introduces the fundamental theory behind beamforming antennas. In addition, calculation methods for radiation patterns with simulations results, as well as some real world measurement results for small linear arrays are shown. Due to the likely bandwidths in such applications, a non-standard way of graphical representation is proposed.

The software interface is an often overlooked, yet critical item in putting together a test system. It’s not enough for a piece of equipment to work well in isolation. In a production environment it must interact with and take commands from other modules, and in a laboratory setting it must work seamlessly with multiple hosts. Understanding some of the potential interface barriers and how to remove them is an important first step before evaluating any piece of test equipment.

Concrete and confined use cases such as mobile voice in 2G and mobile data in 4G dominated the definition of past cellular technologies. In contrast, 5G introduces a paradigm change towards a user/application centric technology framework that aims to support the following triangle of important use case families. The enhanced mobile broadband (eMBB) use case represents the well-known continuation of the ever-increasing requirement to support both higher peak data rates per user and more system capacity.
