  • The challenge of testing 5G antenna performance

    Rohde & Schwarz presents the R&S®ATS1000 antenna test system, a highly accurate solution for testing 5G antennas up to mmWave frequencies in a mobile shielded chamber.

  • LTE and Bluetooth® in-device coexistence with WLAN

    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.

  • LTE UE receiver performance measurements

    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.

  • Antenna Array Testing - Conducted and Over the Air: The Way to 5G

    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.

  • ATS1000: Passive Antenna Measurement and Nearfield - Farfield Transformation

    This application note describes how to measure the antenna pattern of a mm-Wave device in the R&S®ATS1000 shielded chamber. This includes the required calibration of the measurement setup and a possible near field to far field transformation when measuring larger devices.
