NTT DOCOMO and NEC Corporation have completed a test to evaluate the energy efficiency and performance of AWS Graviton2 processors across major parts of the 5G core network (5GC).


The testing indicated a 72% decrease in power usage when compared to existing x86 processors while utilizing NEC’s 5GC software running on AWS Graviton2. The study examined performance in a 5GC hybrid cloud environment using AWS Graviton2 and the Network Functions Virtualization (NFV) infrastructure installed locally by DOCOMO..


These findings promote the creation of a hybrid cloud environment for telecommunication networks in the future, allowing mobile carriers to offer their users better networks that are disaster-resistant.


Following the end of this first phase, the companies will perform a second phase experiment on DOCOMO’s premises to verify the 5GC network operation on AWS Outposts equipped with Graviton2 processors.


Naoki Tani, Executive Vice President, Chief Technology Officer, Executive General Manager of the R&D Innovation Division of NTT DOCOMO, said: “We are delighted to announce that we achieved significant reduction of power consumption of 5GC thanks to NEC’s advanced, cloud-native 5GC software and AWS’s innovative and highly efficient Graviton2.”


“The significant power reduction achieved through this trial indicates a big step forward in commercializing environmentally friendly, sustainable, next-generation mobile infrastructure,” commented Atsuo Kawamura, Executive Vice President, NEC.


Adolfo Hernandez, Vice President and General Manager Telecom Industry Business Unit at AWS: “AWS is committed to building a sustainable business for our customers and the planet, and is thrilled to see the power savings Graviton2 delivers in telecommunications. 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.”
