Japan’s 5G network tests ARM chips and claims power consumption drops • The Register

NTT Docomo and NEC have conducted tests showing that ARM-based Graviton2 processors consume 72 percent less power compared to X86 chips while running NEC’s 5G core software as part of the NTT Docomo 5G network.

The two companies said they have completed a trial to test the power efficiency and performance of AWS Graviton2 processors used in key elements of the 5G core network operated by the Japanese telecom company.

NEC provides the 5G core network systems and base stations (5G radio units (RUs)) plus central units and distributed units for the 5G standalone services that NTT Docomo launched commercially in Japan last year.

According to the two companies, their trial tested performance in a 5G core hybrid cloud environment and used AWS Graviton2 processors and NTT Docomo’s Network Function Virtualization (NFV) infrastructure. In this proof-of-concept configuration, the use of Graviton2 chips enabled an average 72 percent reduction in power consumption, they claim.

Having completed this first phase, the companies are now planning to conduct a second phase of testing to test the 5G core network functions running on AWS outposts equipped with Graviton2 processors deployed at NTT Docomo’s premises.

AWS Outposts is a kind Cloud in a Box Solution that AWS customers can deploy on their own premises.

That Graviton2 was introduced by AWS to its cloud infrastructure in 2020. It’s a 64-core processor based on Arm’s Neoverse N1 design, clocked at 2.5 GHz.

NEC claimed that the Graviton2 processors deliver a big leap in performance and help reduce the carbon footprint of IT workloads through energy efficiency.

The company also said that many telecom workloads need to reside on edge infrastructure with performance and space constraints, and Graviton2 offers efficiency with low cost, low power consumption and a small hardware footprint.

Naoki Tani, EVP and CTO of NTT Docomo’s R&D Innovation Division, said in a statement the company is pleased to have achieved a significant reduction in power consumption for its 5G core network.

“We will continue proof-of-concept collaboration with NEC and AWS to provide our customers with green and disaster-resistant 5G network services in the future,” he said.

Adolfo Hernandez, AWS VP and GM for the Telecom Industry business unit, said in a statement, “AWS is committed to building a sustainable business for our customers and the planet and is excited about the energy savings that Graviton2 offers in telecoms.

“We look forward to continuing to work with NTT DOCOMO and NEC to further expand the use of cloud and AWS technologies to advance sustainability and resiliency goals.”

The Japanese infrastructure giant has been tapped to fill the Huawei-shaped hole in the UK telco market in 2020, with tests of OpenRAN technology taking place in Wales in partnership with NEC as part of the NeutrORAN project. It was completed earlier this month Experiment with its 5G Massive MIMO tech in France’s experimental 5G standalone network.

According to that Global Mobile Suppliers Association, at least 19 operators in 15 countries/territories are said to have launched public 5G SA networks. Another four have deployed 5G SA technology but have not yet launched services or only tentatively rolled out. Most current deployments are NSA or non-standalone applications piggybacked on 4G infrastructure.

According to the GSA, several Chinese operators have rolled out standalone 5G, including China Mobile, China Telecom and China Unicom. In October 2021, SoftBank Corp. first Japanese operator to launch an SA network. ®
