This paper presents a method for modeling and evaluating a new NB-IoT (Narrowband Internet of Things) system in a combined multi-domain simulation environment. Due to the complex analog and digital components of the communication system, accurate modeling is crucial to understanding system behavior. Realistic modeling examples are used with a new simulation method for an in-depth study of the RF transceivers, advanced modem technology and non-ideal hardware.

Get prepared for 400Gb/s and all the new evolving standards on your path to 400Gb/s - in core fiber networks and data centers, for electrical and optical interconnects. Tackling this data rate comes along with novel test challenges and requirements. The Keysight 400G poster, titled “Master 400G,” provides insights into the new parameters that have been defined for judging signal quality under tightening conditions. Gain insight from Keysight industry experts on a wide range of topics from 5G and Electronic Warfare, to Radar Fundamentals, The Calibration Game, and more with 5 technical posters to help smarten up your lab and office walls.
This white paper introduces some of the fundamental theory behind beamforming antennas. In addition to these basic concepts, calculation methods for radiation patterns and a number of simulations results, as well as some real world measurement results for small linear arrays are shown. Due to the bandwidths likely to be employed in such applications, a non-standard way of graphical representation is proposed.
The most effective wireless researchers have something in common: they understand the complexity of looking at standards, what their competitors are doing, and how-to work towards 5G development for their organization.
Our complete guide will provide an overview and update covering: PHY and MAC layers addressed in RAN 1 and RAN 2; ITU requirements; anticipated timelines towards a 5G future; early non-standard 5G releases; and a look at current 5G trial deployments. This resource guide reflects up-to-date 5G specifications as of June 2017.

In 5G, the use of massive MIMO is a revolutionary idea. It has major implications for development and implementation within the 5G ecosystem. It also affects the set of tools you'll need to characterize and validate these highly complex systems. To help you accelerate from idea to reality, our latest 5G application note reviews the MIMO process, outlines the challenges to implementation, and presents solutions for simulation, design and test of massive MIMO systems.
What is a Network Analyzer? One of the most common measuring tasks in RF engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites.

Everywhere you look today, 5G is at the center of conversations about exciting new technology. Recent announcements from Mobile World Congress 2017 in late February indicate that 5G is already here. The truth is that 5G isn’t here yet, but we are getting closer. The past year has been busy in all aspects of the communications community, from the work on the standardization process to updates from regulatory bodies to our understanding of the channel for new proposed millimeter wave (mmWave) frequencies to the new technology under development that will turn 5G into a commercial reality. Last year, I wrote a paper called “mmWave: The Battle of the Bands” to provide an overview of the technologies being proposed for mmWave frequencies. In this paper, I’m building on that information by examining mmWave for communications and presenting an update to the question on everyone’s mind: What is 5G and when will it be here?
