Deeper into the Networked Society

Ulf Ewaldsson

Earlier this year Ericsson launched its new vision: a Networked Society, where every person and every industry is empowered to reach their full potential. Technology leadership is about putting this vision into practice. It’s about developing connectivity technology to be an integral part of the fabric of what we do on a daily basis, whether it is at work, at school, at home, outside, on the way to somewhere or on the way back from somewhere.

The aims of each individual or enterprise are highly varied; people and companies want coverage, capacity, reliability, availability and resilience with an appropriate level of security. The one-size-fits-all network no longer fits well with the need to customize network characteristics to suit user’s needs and what they are prepared to pay for. With cloud technologies, SDN and NFV as a foundation, I see the developments we are working on, moving toward 5G, are focused on the ability to provide connectivity to suit each and every use case.

The traditional way of building services and applications by packaging functionality and data together and ensuring it was secure has worked well for services made and delivered by one vendor. Some could even benefit from being tightly bundled with hardware. But this approach doesn’t lend itself to highly innovative solutions, reusability, fast time to market, and use of generic hardware.

Instead, applications and services are being mashed together from lots of other internet services. The freedom to innovate that this enables however results in security continuing to be one of our industry’s biggest challenges. And as web services and programmable routing technology are deployed on platforms that exploit virtualization, ensuring security becomes even more complex. Trusted computing aims to provide a way to meet the evolving security requirements of users, businesses, regulators and infrastructure owners.

The developments that I would specifically like to highlight relate to handling expected growth in traffic volumes, capacity and machine-type communication.

Building heterogeneous networks is an effective way to expand networks to handle traffic growth. However, the additional small cells included in these networks need to be provided with flexible and cost-efficient backhaul. Our research shows that non-line-of-sight backhaul in licensed spectrum is a future-proof technology in this area.

When it comes to capacity, one of the significant challenges is providing radio capacity indoors. Somewhere around 70 percent of all traffic is generated indoors and our research has resulted in a novel fronthaul solution with a flexible radio architecture. We wanted to address the issue of indoor capacity from an ecosystem point of view, with an emphasis on cost control at every phase. From installation to operation, we aimed to create a special indoor radio that works well in large buildings – a solution that integrates well with outdoor solutions.

Capillary networks offer a smart way to connect the internet of things, but they require some additional functionality. The use cases for machine-type communication vary greatly from one application to the next and so rather than building systems with a one-size-fits-all approach, capillary networks will be designed to fit the application.

All of these developments lead to a network architecture that is more flexible to meet the demands of future use cases.

As always, I hope you enjoy our insights.

OpenStack as the API framework for NFV: the benefits, and the extensions needed

OpenStack as the API framework for NFV: the benefits, and the extensions needed

April 2, 2015

Network Functions Virtualization (NFV) offers a flexible and scalable way to deliver and deploy Virtual Network Functions (VNF) services. Use of virtualization and cloud computing is becoming increasing popular as these techniques can dramatically reduce time-to-market. However, the transformation to VNF services and deployment scenarios needs an API framework – and OpenStack is a suitable candidate. But is it enough, and what improvements are needed?

Setting the future media services architecture

Setting the future media services architecture

February 24, 2015

Many industries are undergoing a transformation, moving away from physical products and communication to virtual products and massive digitalization. The benefits of an ICT transformation that takes advantage of commercially available IT systems, networking equipment, and cloud-based services are many. The media industry in particular stands to benefit greatly. As we move deeper into the Networked Society, media production and consumption will take on a more prominent role in shaping requirements related to network design and performance.

Wi-Fi calling – extending the reach of VoLTE to Wi-Fi

Wi-Fi calling – extending the reach of VoLTE to Wi-Fi

January 30, 2015

Using untrusted Wi-Fi to carry voice and video communication is an opportunity to extend current voice and video calling over LTE (VoLTE/ViLTE) services in, for example, indoor locations where cellular coverage may be spotty. Closely aligned with VoLTE architecture, Wi-Fi calling supports mobility between LTE and Wi-Fi accesses making the resulting user experience a seamless one, and offers a scalable deployment opportunity for network operators.

How do you design a small radio to fit the interiors of large spaces, yet powerful enough to meet future requirements for indoor radio capacity? This was the question we asked ourselves when we began to develop a solution to provide high-capacity radio for indoor environments.

Heterogeneous networks are an effective way of expanding networks to handle traffic growth. However, the additional small cells included in heterogeneous networks need to be provided with backhaul – in a way that is flexible and cost-efficient. Our research shows that non-line-of-sight (NLOS) backhaul in licensed spectrum up to 30GHz is a future-proof technology for managing high volumes of traffic in heterogeneous networks.

Trusted computing for infrastructure

Trusted computing for infrastructure

October 24, 2014

Modern internet services rely on web and cloud technology, and as such they are no longer independent packages with in-built security, but are constructed through the combination and reuse of other services distributed across the web. While the ability to build applications in this way results in highly innovative services, it creates new issues in terms of security. Trusted computing aims to provide a way to meet the evolving security requirements of users, businesses, regulators and infrastructure owners.

A capillary network is a local network that uses short-range radio-access technologies to provide local connectivity to things and devices. By leveraging the key capabilities of cellular networks – ubiquity, integrated security, network management and advanced backhaul connectivity – capillary networks will become a key enabler of the Networked Society.
