Challenges in 5G User Equipment Design

Future 5G UE equipment will be more complex with many new and existing challenges. In addition to RF challenges, power and battery related issues will also prove challenging. In this short video, technology marketing manager Reiner Stuhlfauth explains these key challenges with a focus on power supply issues

The Evolving Need for Over-the-Air (OTA) testing

As the frequency and complexity of 5G devices increases, the ability to perform conducted measurements will become more difficult. As a result, the ability to make accurate and repeatable measurements over-the-air will be required. In this short video, technology marketing manager will explain why 5G devices will require OTA testing

Introduction to Massive MIMO

Massive MIMO will play a key role in 5G systems. In this short video, technology marketing manager Reiner Stuhlfauth will explain the need for Massive MIMO and how it evolved within mobile communication systems.

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.
