The R&S®DST200 RF diagnostic chamber is the ideal environment for RF analysis during development. It supports a wide range of radiated test applications for wireless devices and fits on any R&D lab bench, where it can be used at all times during the product design and optimization phase. The R&S®DST200 effectively assists in achieving high first-time pass rates during final type approval, which saves time and money.

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.

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 "Millimeter-Wave Beamforming: Antenna Array Design Choices & Characterization" 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.

Modern mobile phones can support cellular and noncellular wireless communications standards at the same time. This means, however, that the subsystems must operate in very close proximity to each other within a single device (in-device coexistence). The resulting high level of reciprocal leakage can at times cause considerable interference.This application note employs preliminary theoretical analysis and demonstrates how the problems of indevice coexistence can be measured.For german version please visit http://www.rohde-schwarz.de/appnote/1ma255.

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.
