IBM and Ericsson on Monday announced a research breakthrough that could accelerate the launch of 5G communications networks and support new mobile enterprise and user experiences enabled by very high data rates, including IoT, connected vehicles, and immersive virtual reality.

The companies have created a compact silicon-based millimeterWave (mmWave) phased array integrated circuit operating at 28GHz that has been demonstrated in a phased array antenna module designed for use in future 5G base stations.

2017 has been described as a defining year for 5G. More countries and governments are opening up new frequency portions of the electromagnetic spectrum, including portions known as millimeter wave bands, which are more than 10 times higher than the frequencies currently used for current mobile devices, offering a new source of bandwidth for cellular networks that are being made available for 5G networks.

Scientists at IBM Research and Ericsson reached their breakthrough as a result of a two-year collaboration that set out to develop phased array antenna designs for 5G. IBM’s expertise in highly integrated phased array mmWave IC and antenna-in-package solutions, together with Ericsson’s expertise in circuit and system design for mobile communications, helped the team reach several new technological milestones.

Thomas Noren, Senior Advisor, Business Unit Network Products, Ericsson, says: “There has been a lot of encouraging progress in 5G standardization last year including the beginning of live field trials. Big efforts in research and development are key to this and our collaboration with IBM Research on phased array antennas can help operators to effectively deploy radio access infrastructure necessary to support a 5G future. New use cases and applications that span human machine interaction, Virtual Reality, smart home devices and connected cars will depend on innovative technologies that can bring the promises of faster data rates, broader bandwidth and longer battery life to reality.”

“The development of this 5G millimeterWave phased array is an important breakthrough, not just because of its compact size and low cost, which make it a very commercially attractive solution for network equipment companies and operators, but its potential to unleash and inspire brand new ideas and innovations we haven’t yet imagined, thanks to a fully networked society,” said Dr. Dario Gil, Vice President of Science & Solutions, IBM Research.

Making 5G A Reality
The first release of the 3GPP 5G specification is targeted to be ready by 2017/2018, but there has already been much progress in the industry with field tests and demonstrations of new user experiences and capabilities made possible by the higher bandwidth, lower latency, greater density and lower energy requirements of 5G networks.

5G is expected to support data rates exceeding 10Gbps in certain scenarios. New capabilities are designed to allow users to download a full-length HD movie in seconds, provide very high bandwidth and uninterrupted live streaming experiences in highly dense environments such as sports or concert venues, experience ‘life-like’ response times to enable remote surgery or fully immersive virtual reality experiences, as well as see battery life of 10 years for remote cellular devices that may be part of IoT environments.

The Phased Array Antenna Module Breakthrough
For future 5G phased array deployments to be commercially viable the size, weight, cost and performance of the component are important factors.

The IBM and Ericsson team’s result, the world’s first reported silicon-based mmWave phased array antenna module operating at 28GHz, is a significant step towards meeting this challenge. The module, which consists of four monolithic integrated circuits and 64 dual-polarized antennas, measures approximately 2.8” by 2.8”, or about half the size of a typical smartphone. Achieving this compact form factor is necessary to support the vision of this technology’s widespread deployment, especially in indoor spaces and dense downtown areas.

Another performance advance reported by the team is the demonstration of concurrent dual-polarization operation in transmit and receive modes.

This capability enables one phased array antenna module to form two beams simultaneously, doubling the number of users to be served at the same time and so improving the overall value and economics of the technology.

A major hurdle for the use of mmWave signals in mobile communications is achieving sufficient range between radios to support target applications. At 28 GHz, each antenna is tiny and individually would support short communication distances, but combining multiple such tiny antennas not only increases the range but also enables steering of signals in specific directions. The IBM and Ericsson team’s phased array design supports beam-steering resolution of less than 1.4 degrees for high precision pointing of the beam towards users.

IBM Communications Circuits & Systems Innovation
IBM Research has a long history designing and developing integrated circuits and phased arrays, and were pioneers of the first monolithic mmWave radio in 2006. In 2013, the team presented results of a highly integrated mmWave phased array transceiver for both mobile communications and radar imaging applications that laid the foundation for this latest scientific work.

The IBM scientists have also explored how mobile handsets will communicate at new mmWave frequencies, showing a path for how mmWave 5G radios could be implemented in mobile phones.

A paper describing the IBM Research and Ericsson team’s work, “A 28GHz 32-Element Phased-Array Transceiver IC with Concurrent Dual Polarized Beams and 1.4 Degree Beam-Steering Resolution for 5G Communications,” will be presented on February 7 at the 2017 International Solid State Circuits Conference in San Francisco.

Defending the Foundations for Connectivity

Published

By Engr. Gbenga Adebayo

In 2001, when the first GSM call was made in Nigeria, how many of us would have envisaged the digital world that we live in today?

Defending the Foundations for Connectivity

Gbenga Adebay, chairman, ALTON

The pace of growth and the rate of adoption of telecoms solutions in Nigeria has been revolutionary. It is a globally acknowledged case study that we should be proud of and a clear demonstration of what can be achieved.

Almost all of us today are reliant on the network connectivity that it has enabled in different shapes and forms. From the simple need to communicate with loved ones, to the digital platforms that enable our access to and consumption of entertainment, financial products and other critical services.

Our reliance on these systems is becoming more and more acute, whether it is citizens, governments, or corporations.

System downtime is increasingly disruptive and offline manual redundancies are often in the advanced stages of being phased out. The pace of this transition is not slowing down. With the core infrastructure in place, innovation is driving the exponential growth of services that ride on it. From the fully adopted social media that has changed the way we interact, to the emerging Artificial Intelligence (AI) revolution.

While this innovation is enabling exciting new possibilities, there is a tendency to focus on those opportunities, to the detriment of the core infrastructure on which it rides.

It is imperative that we retain a focus on the optimisation of that infrastructure and enable continued investment in its development.

We have seen how the transition from 2G, through to 3G, 4G and 5G have each enabled the development of more and more sophisticated solutions.

The continued development of core infrastructure has to be sustainable, and over the last few months we have begun to see the challenges that the operators that provide it are facing.

Both MTN and Airtel have declared significant foreign exchange (FX) losses in Nigeria, and the stress is not linked to them alone.

The entire ecosystem is battling with a range of challenges that must be addressed. If we fail to do so, the downstream impact on innovation will be severe. Telecoms infrastructure requires a base level of investment to maintain its current capabilities, and significant additional investment to expand and grow. It is capital intensive and that capital has to be generated through sustainable business models.

At the heart of the challenge the industry faces is the issue of rising costs.

Recent financial losses are directly linked to the cost of operating towers that rely on inputs like diesel, which have increased significantly as the Naira has depreciated.

The provisions large telecom companies have had to make, and the consequent losses and impact on their reserves is a red flag.

It tells us that business as usual is not sustainable. If we continue as we are, then those companies will struggle to continue to invest in and maintain existing services.

But those costs are not the only challenge. General cost inflation, multiple taxation, regular and damaging vandalisation of infrastructure and the costs associated with regulatory compliance all help contribute to the high cost of operations.

We cannot continue to follow a path that asks those companies to simply accept those rising costs. It is no longer sustainable, and we have reached an inflection point.

This is a critical moment for the industry.

How we approach and resolve it will define the future of Nigeria’s digital economy.

If you want to be able to enjoy the benefits that digitisation brings. If we want the infrastructure that enables AI and helps us drive growth, then we must take action now.

Cost-reflective tariffs, like it or not, are simply non-negotiable. We have seen the impact of price controls in other segments of the economy, like power.

If providers cannot operate sustainable business models, then they stop investing. When that happens, the existing infrastructure starts to crumble.

For power, a consumer can choose to take ownership of the solution by buying a generator, or a solar panel.

For fuel, the government can step in as the provider of last resort and manage a subsidy regime that mitigates the impact on the population. Those options are not available in the telecoms sector. There is no self-help solution.

We fully understand and appreciate the financial stress that Nigerians are experiencing today. The cost of living is the single most significant factor in most people’s daily lives.

But those people are still able to enjoy the benefits that connectivity brings, at the price they paid before these challenges became so acute.

Imagine a future in which the gains of the last twenty years are reversed. Nigeria, and Nigerians simply cannot afford it. The pain that we would feel under those circumstances would be exponentially worse.

We need to find a long-term, sustainable and manageable solution to this problem. Prices will need to rise, but action needs to be taken in a measured way, through sustainable conversations and partnership with the government. It is time to address this head on.
