The Blurring Lines of 5G

With the implementation of 4G, many companies took liberties in saying they had 4G networks even though they did not meet the performance specifications of the 3GPP standard just so they could be first to market (or at least an early provider). This is already happening now with 5G.

A Look Ahead at Articles for the First Quarter of 2019

Commercial 5G service has been formally launched in the US and Korea with the first smartphones expected before June in 2019 in both countries. 5G has certainly happened faster than expected a few years ago and should enable a year with increased activity in the IoT market. The US Defense budget is healthy in response to an increase in sophistication of the Chinese and Russian defense capabilities with solid-state technology and flexible, software driven platforms being emphasized. So we expect 2019 to be an exciting year on the editorial front with many new innovations given solid financial support in these areas and others.

Measurement Instruments for the Many

Rohde & Schwarz has always been known for high end, very accurate instruments in the high frequency and high speed industry which typically translates into high cost products. Some of these high precision instruments can cost hundreds of thousands of dollars. But did you know that R&S has a portfolio of value class instruments with more than 100 products and 300 accessories? Some new introductions included the R&S®RTB2000 Oscilloscope, the R&S®RTM3000 Oscilloscope, the R&S®RTA4000 Oscilloscope, the R&S®FPC1500 Spectrum Analyzer and the R&S®HMP4040 Power Supply. From their recent release, here is a summary of the new value instrument additions they highlighted.

Why 5G Wireless Technology Will Place a Greater Demand on Cables

Jean-Jacques Sage, Products and Solutions Manager for Telecom Networks at Nexans

The 5G revolution promises astonishing gigabit-per-second data rates and near-instantaneous connectivity. It is projected to have a mass impact across many industries and change the lives of billions of both consumers and suppliers worldwide. Like every generation of new wireless technology, 5G will dramatically increase the speed and volume of data transfer, but this will have more profound consequences than ever before.

Ericsson Mobility Report Nov 2018 Summary

Ericsson has just released their Mobility Report Nov 2018 and on a global level, they predict major 5G network deployments from 2020 and by the end of 2024 estimate 1.5 billion 5G subscriptions for enhanced mobile broadband. They think this will account for close to 17 percent of all mobile subscriptions at that time. Since the report is more than 30 pages, I thought I would extra some of the overview and devices specific data important to the RF/microwave community.

Skin Depth and its Impact on Different RF PCB Structures

Skin depth is often used to describe the behavior of current flow through circuit conductors, i.e., the copper on a PCB, especially at RF/microwave frequencies. Direct current (DC) may exhibit evenly distributed flow through a conductor such as copper, but high-frequency, sinusoidal current experiences changing energy density as it flows through a PCB’s conductors, with areas of lower and higher current density relative to the surface of the conductor.

Let’s Talk 6G

In June, the first 5G specification was finalized as 5G NR phase I (release 15) and next year will see the completion of phase II for the 5G NR specification. 5G started in the U.S. in Oct this year when Verizon released the first commercial 5G service with the deployment of mmWave Fixed Wireless Access service in several cities. AT&T is starting the deployment of the first standards-based 5G mobile service now and T-Mobile plans to start in the first half of 2019. Although it will be several years before 5G becomes prevalent to the consumer around the world, we have to ask what’s next.

Exploring the Future of 5G

By Charles Schroeder

Testing 5G components and devices with over-the-air (OTA) methods instead of the cabled methods currently in use will be necessary to validate the performance of 5G technology. As engineering leaders, we need new test methods to ensure the viable commercialization of 5G products and solutions across many industries and applications.

What We Learned at the 5G Symposium at EDI CON USA 2018

5G mmWave is here!

With 5G mmWave technology already deploying in the US, I was glad to oversee the EDI CON USA 2018 5G Symposium in Oct that included a full afternoon of sessions including topics such as the best RF architectures for 5G, semiconductor tradeoffs for 5G mmWave devices, antenna modeling, simulation of fixed wireless access systems, design of a 28 GHz filter and silicon active antennas for mmWave applications.
