CTO's comments about the latest magazine

We are publishing this magazine shortly after the first release of a completely new standard – 5G – from 3GPP. Fittingly, many of the articles in this issue relate to what we think is most important in 5G and how to address the new opportunities that it entails.

One of the key reasons for the flexibility provided in 5G is the desire to support industries to use connectivity, virtualization, machine intelligence and other technologies to change their processes and business models as part of the next industrial revolution, Industry 4.0. It is therefore a pleasure to be able to include an article that we have co-written with Comau and the Sant’Anna School of Advanced Studies on the topic of industrial automation.

I hope you find the contents of this issue of the magazine as intriguing as I do. Please feel free to share links to the magazine and/or individual articles via e-mail or social media.

CTO's comments about the latest article

Active Queue Management (AQM) is a well-established technique for managing the frequent and substantial fluctuations in bandwidth and delay that commonly cause delays in networks. Traditional AQM tends to work well in fixed networks, where bottleneck link bandwidth varies little over short time durations. Mobile networks exhibit vastly different properties of fluctuating bandwidth, which requires a more refined approach.

The latest Ericsson Technology Review article presents an innovative concept for virtual AQM. vAQM is centralized and applied per user and per flow and considers the current bottleneck of the link bandwidth to the user. Our testing has shown that vAQM that is centralized upstream, rather than being deployed in the bottleneck nodes as it is in classic AQM, results in a substantial reduction in bufferbloat.

Low latency, high flexibility - Virtual AQM

April 10, 2018

Virtual Active Queue Management is an innovative approach to buffer management that does not require deployment in the network nodes where the buffering takes place. Instead, it is deployed as a centralized network function, which allows for simpler configuration and increased flexibility compared to traditional Active Queue Management deployments.  


Enabling intelligent transport in 5G networks

March 21, 2018

Increasing RAN and mobile broadband service capacity, new 5G-enabled services and the dynamic deployment flexibility of the 5G RAN split architecture are just a few examples of the growing list of demands that the transport network must meet. These demands are particularly evident in the fronthaul portion of RAN, where latency and synchronization requirements are especially challenging. Overcoming the 5G transport challenge requires a level of flexibility that would be very costly without automation. Our proposed solution provides the requisite intelligence and acts as a catalyst for automation, enabling operators to meet the 5G requirements of multiple use cases while simultaneously reducing opex.

Industrial automation enabled by robotics, machine intelligence and 5G

February 15, 2018

The emergent “fourth industrial revolution” will have a profound impact on both industry and society in the years ahead. Robotics, machine intelligence and 5G networks in particular will play major roles in this revolution by enabling ever higher levels of automation for production processes.
