Key Challenges with Massive MIMO

A key underlying technology for 5G, Massive MIMO systems are complex and combine technologies such as beam forming, spatial multiplexing and large antenna arrays. In this short video, technology marketing manager Reiner Stuhlfauth explains the technology and key challenges associated with these systems

Beam Forming Implementation

Beam forming involves an antenna array in which the amplitude and phase of each antenna element is adjusted. In this short video, technology marketing manager Reiner Stuhlfauth discusses the pros and cons of analog, digital and hybrid beam forming systems.

Beam Forming for Pre-5G

Pre-5G will be focused on Fixed Wireless Access. Using an antenna array at the base station, multiple beams can be created to direct the power and direction of the signal to a user or group of users. In this short video, technology marketing manager Reiner Stuhlfauth explains these key technology aspects.

Pre-5G vs. 5G: Technology Overview

Primarily designed for Fixed Wireless Access, Pre-5G will leverage many aspects originally introduced with LTE, but with some scaling differences. 5G, on the other hand, is evolving to become a very flexible radio architecture build on OFDMA to accommodate the hundreds of use cases for 5G. In this 12 minute video, technology marketing manager Reiner…

Pre-5G vs. LTE: Technology Overview

Pre-5G is currently being investigated and developed by some companies around the world as means of deploying Fixed Wireless Access (FWA). Pre-5G has many similarities to LTE, but also some key differences. In this short video, technology marketing manager Reiner Stuhlfauth outlines these points.

5G Technology Multiple Access Schemes Resource Spread

As the densification of networks and the need for more capacity continues, new multiple access technologies will be required to provide a high quality of experience to individual users. In this 5 minute video, Rohde & Schwarz Technology Manager Reiner Stuhlfauth discusses underlying concepts and considerations for new multiple access schemes that are being considered…

Characterization of mm-Wave Channel Sounders up to W-Band and Validation of Measurement Results

In this paper, the characterization of mm-wave channel sounders and validation of measurement data are discussed. Suitable procedures and metrics like the dynamic range and the maximum measurable path loss are proposed for this purpose. They are illustrated by using measurement data at 28 and 82GHz from back-to-back measurements in the laboratory as well as…
