  • Multi-Channel Signal Generation Applications with R&S®SMW200A – Overview

    The R&S®SMW200A vector signal generator has the outstanding ability to simultaneously generate up to eight independent signals from a single instrument. The advanced multi-channel architecture allows realizing even complex applications like MSR, carrier aggregation, MIMO or enhanced interference scenarios with a minimum of effort.This application note gives an overview of common multi-channel application examples and how to equip the Rohde & Schwarz signal generator R&S®SMW200A appropriately.

  • LTE- Advanced (3GPP Rel.12) Technology Introduction White Paper

    This white paper summarizes significant additional technology components based on LTE, which are included in 3GPP Release 12 specifications. The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of commercial networks is strongly increasing around the globe. LTE has become the fastest developing mobile system technology ever. As other cellular technologies LTE is continuously worked on in terms of improvements. 3GPP groups added technology components according to so called releases. Initial enhancements were included in 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10 a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. Therefore LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12.

  • LTE Location Based Services Technology Introduction White paper

    LTE Location Based Services (LBS) involve the process of determining where a device is located. Global Navigation Satellite System (GNSS) based solutions are highly accurate and the technology of choice for absolute position accuracy, providing the device has a good line-of-sight, but this is not always the case. A device can be in a highly dense urban environment with reduced satellite visibility or indoors with very low signal levels.These limitations of GNSS systems have meant that LTE cellular based alternatives have been developed within 3GPP Release 9 and onwards.They are described in this white paper.

  • WLAN Traffic Offload in LTE

    This whitepaper provides an overview of the WLAN offload in LTE as standardized by 3GPP, as well as the enhancements for Wi-Fi standardized by IEEE and the Wi-Fi Alliance. It also describes access methods in the joint network, treats the security, and describes IP mobility. In addition network discovery and selection are explained.

  • Narrowband Internet of Things

    As part of Release 13, 3GPP has specified a new radio interface, the Narrowband Internet of Things (NBIoT). NB-IoT is optimized for machine type traffic. It is kept as simple as possible in order to reduce device costs and to minimize battery consumption. In addition, it is also adapted to work in difficult radio conditions, which is a frequent operational area for certain machine type communication devices. Although NBIoT is an independent radio interface, it is tightly connected with LTE, which also shows up in its integration in the current LTE specifications.In this whitepaper we introduce the NB-IoT technology with an emphasis on the tight connection to LTE.

  • Testing of LTE beamforming

    LTE is becoming the predominant wireless technology. Among several new features of this standard, the multiple input multiple output (MIMO) technology offers various advantages.It improves the throughput, extends the reach, reduces interference and improves the signal to interference plus noise ratio (SINR) with beamforming. LTE supports various modes in order to optimize the transmission settings.An LTE MIMO base station consists of a baseband unit, a remote radio head (RRH) and an array of up to eight antennas. The RRH upconverts the digital signals of the baseband unit into analog signals for each antenna.

  • Enabling smart macro network enhancements

    Rohde & Schwarz mobile network testing solutions enable operators to efficiently increase network capacity via hardware-related, capacity-enhancing features such as antenna tilt optimization, carrier aggregation, 4x4 MIMO and 6-sector sites.
