Nokia back in 5G Game and Vying for Open RAN & 6G Success

Nokia announced their 5G progress at Global Analyst Forum 2021. In a blog post, Tommi Uitto, President of Mobile Networks at Nokia wrote:

“We bet on the right horse choosing Nokia” a customer shared his feedback in a recent meeting after my update on Nokia’s 5G portfolio. We’ve received similar recognition from other customers too: “Congratulations on the catch-up in 5G,” “We of course monitor our customers’ experience and in Nokia-supplied networks it has been excellent,” “Nokia is back in 5G.”

The new 5G portfolio we’ve launched this year continues our promise to deliver and further improve the performance of our networks:

  • We’ve launched our new AirScale radios, including the industry’s lightest high-power, 400MHz 32TRX Massive MIMO. These radios contribute to our 50 percent reduction in power consumption of Massive MIMO radios from 2019 to 2023.
  • Our AirScale baseband is the industry benchmark for flexibility and capacity. It also comes with significantly improved energy efficiency, reducing the baseband power consumption by up to 75 percent. This also contributes to our commitment to halve base station power consumption by 2023.
  • We’re on track to power our full portfolio with latest ReefShark System-on-Chips by the end of 2022.
  • And this year, we brought together our software to a common development trunk, meaning updates to software from 2G to 5G in a single release, bringing our customers the speed and quality they need.

Where we are now is the result of hard, focused execution on our strategic priority to build 5G technology leadership and improve our portfolio competitiveness over the past three years. Coupled with industry-leading SON and network management, as well as digitalized services boosting the speed and quality of deployments, we have a good racehorse now.

Here is a short video from Tommi:

One of the other interesting area that he covered was on Open RAN, or O-RAN as Nokia prefers to use  it. Quoting from the blog post:

Preparing for the future opportunities starts now. Undoubtedly, one key focus area continues to be Open RAN. Nokia is the leading contributor in the O-RAN Alliance and our new AirScale portfolio is already O-RAN ready, supporting our efforts to develop cloud-based, open approaches to building networks. This is all happening in tight cooperation with our customers like NTT Docomo, or Deutsche Telecom with whom we just announced opening a new open lab "i14y" to accelerate network disaggregation and Open RAN. There are many steps to build the O-RAN ecosystem, and we expect this to develop over the coming years but would not expect real commercial deployments before 2023 (perhaps earlier for some trials).

And of course, no discussion is complete nowadays without mentioning 6G:

Network efficiency and optimization utilizing 4G/5G slicing, AI/ML and continuously improving energy efficiency are also key focus areas as we continue to enhance our offering, on the runway to 5G Advanced and ultimately 6G towards the end of the decade. Although it’s early stages on the 6G journey, we envision it to bring massively more capacity, adaptive AI interfaces and deep learning techniques. But when the time of 6G comes, we should not assume we’ll get to start from a “clean slate”. Our customers will want to ensure a seamless evolution of architectures, chipsets, software and 5G/6G platforms. It’s going to be an exciting evolution from 5G to 6G.

The slides from the Analyst Forum is available here.

Matthew Baker, Head of Radio Physical Layer and Co-existence Standardisation at Nokia recently spoke about Nokia's vision of 5G-Advanced. Here is his talk:

Demos from Ericsson's Radio Tech Day 2021

Ericsson's Radio Tech Day is a cyclical meeting intended for the telecommunications industry and technical staff of operators in Poland. Engineers share projects, describe best practices and learn from each other's experience. During the conference, the latest solutions in the field of radio and core technology, both in the field of software and hardware, as well as the achievements of start-ups cooperating with the company, are presented.

The following video is from the recent event held last month:
