This application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863. The included software sequence performs decoder/encoder calibration, connection setup for the UE under test and subsequent speech quality analysis.

This document describes the direct test mode mechanisms for testing Bluetooth Low Energy devices and explains how the direct test mode connection is established. The R&S CMW uses a USB port for the direct test mode connection while the Equipment under Test (EUT) may provide a USB port, a serial port or even a 2-wire UART interface for this purpose. Installing or assigning the right driver for the EUT is the main configuration task on the R&S CMW. For EUTs with USB port, the R&S CMW provides a Bluetooth Low Energy USB driver which has to be assigned to the connected EUT.

This document describes the adaptive frequency hopping mechanism for improved signaling performance in Bluetooth Basic Rate and Enhanced Data Rate devices.The R&S CMW provides this feature for remote operation in TX, Loopback and Connection test mode. Thereby the R&S CMW acts as a master, while the Equipment under Test (EUT) represents the slave(s) of the piconet.

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.

LTE is under continuous development. Release 10 (LTE-Advanced) introduced carrier aggregation (CA) as the primary enhancement. Releases 11 and 12 add several new components to LTE. Some are enhancements to existing features (such as improvements to CA), while others are completely new concepts, such as coordinated multipoint (CoMP).This application note summarizes the Rohde & Schwarz test solutions for LTE-Advanced according to Releases 11 and 12 using vector signal generators, signal and spectrum analyzers and the wideband radio communication tester.
