5g networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: virtualization & massive mimo. this white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (ota) test methods, which result from applying massive mimo antenna technology.this white papers complements the white paper (1ma276) from rohde & schwarz, which introduces fundamental theory behind beamforming antennas and provides calculation methods for radiation patterns, a number of simulation results as well as some real world measurement results for small linear arrays.

lte user equipment (ue) receiver performance has significant impact to cellular radio network coverage and capacity. it determines the maximum data throughput across the air interface between the lte base station (enb, evolved node b) and the mobile network subscriber ue, thus it determines the total capacity across the air interface. therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.this paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (ota) measurements.

in wireless communications, an antenna is an essential device made of conductive metal that transmits or receives electromagnetic radio waves. as the main enabler of wireless communications, antennas must satisfy a number of challenging parameters such as a wide frequency range, flat gain curves and high mechanical stability, so that they can support an ever increasing range of applications.wireless communications testing requires over-the-air (ota) test systems with various antenna types that serve different system functions. a variety of basic antenna designs have become established over time. these include standard gain horn, vivaldi, patch and array antennas. each has unique features that make them ideal for a specific application.test antennas /probes, link/communications antennas and calibration antennas are used in ota test systems.
