Testing LTE Release 9 Features
LTE – the fastest growing mobile radio standard – had its beginnings in 3GPP Release 8. Initial improvements and new features were implemented in Release 9. This Application Note describes the T&M methods for LTE Release 9 features using Rohde & Schwarz instruments.

Testing LTE-A Releases 11 and 12
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.

Introduction to MIMO
Modern radio communication systems have to provide higher and higher data rates. As conventional methods like using more bandwidth or higher order modulation types are limited, new methods of using the transmission channel have to be used. Multiple antenna systems (Multiple Input, Multiple Output – MIMO) gives a significant enhancement to data rate and channel capacity. This application note gives an introduction to basic MIMO concepts and terminology and explains how MIMO is implemented in different radio communications standards.
