NTT DOCOMO & SK Telecom Release White Papers on Energy Efficient 5G Mobile Networks and 6G Requirements
- Possibilities to achieve greater energy savings based on energy consumption levels measured in the two companies’ respective base stations
- Technical analysis of candidate energy-saving technologies, including both hardware and software
- The roles that operators and equipment vendors should play, including the need for greater coordination, in the effort to achieve greater energy savings
For 6G, the paper reviews requirements and challenges including specific performance levels and implementation scenarios, focusing on technical issues of particular importance to mobile operators:
- Performance requirements and implementation scenarios for each frequency band, taking into account the characteristics of each frequency
- Issues concerning coverage and devices in high-frequency bands
- Standardization for migration to 6G architecture and application of cloud-native / open architecture
Going forward, NTT DOCOMO and SKT will continue to collaborate in various technical fields, aiming to enhance the competitiveness and operational efficiency of 5G as well as support the global standardization and technical verification of 6G. They will also collaborate with global telecom operators on 6G standardization and R&D with the goal of building a global ecosystem that encompasses advanced industries and technologies.
“The white papers carry a significant meaning as they mark the first tangible result since entering into a strategic partnership with NTT DOCOMO last year,” said Yu Takki, Vice President and Head of Infra Tech Office of SKT. “Based on our experience and knowhow in 5G, we will continue to collaborate with world-leading operators such as NTT DOCOMO to lead 5G evolution towards 6G.”
Takehiro Nakamura, Chief Technology Architect, NTT DOCOMO, said: “We are delighted to jointly announce two white papers on green mobile networks and 6G requirements as our collaborative achievements with SKT started in November 2022. We will continue to enhance cooperation among the two major Asian mobile operators and promote superior concepts and innovative technologies to the world for the 6G deployment.”
SK Telecom and AWS launch 5G edge cloud service and collaborate on other projects
South Korea’s #1 wireless network operator SK Telecom (SKT) has launched a 5G edge cloud service in partnership with Amazon Web Services (AWS). ‘SKT 5GX Edge’ uses AWS Wavelength at the edge of SKT’s 5G network. SKT said that SKT 5GX Edge will enable customers to develop mobile applications that require ultra-low latency.
With SKT 5GX Edge, applications are connected to ‘AWS Wavelength Zones’, which are located at the edge of SK Telecom’s 5G network, making it unnecessary for application traffic to hop through regional aggregation sites and the public internet.
SKT 5GX Edge with AWS Wavelength is expected to enable SK Telecom’s enterprise customers and developers to build innovative services in areas including machine learning, IoT, video games and streaming using the AWS services, APIs, and tools they already use.
SK Telecom and AWS started operating the first AWS Wavelength Zone in South Korea in the central city of Daejeon (140 kilometers south of Seoul) earlier this month. They plan to expand the SKT 5GX Edge infrastructure to other parts of the country, including Seoul in 2021.
SK Telecom has been cooperating with AWS since February of this year to deploy AWS Wavelength Zones on SK Telecom’s 5G network and worked with 20 enterprise customers to test the service.
SKT and AWS are actively cooperating in the area of non-face-to-face services as demand grows due to the pandemic. The two companies have been working with video conferencing solution provider Gooroomee to build an environment where two-way video conferencing and remote education services are provided without delay, and have realized a service with a latency of less than 100 milliseconds for multiple simultaneous sessions.
“With AWS Wavelength on SKT’s 5G network, customers in South Korea can develop applications that take advantage of ultra-low latencies to address use cases like machine learning inference at the edge, smart cities and smart factories, and autonomous vehicles – all while using the same familiar AWS services, API, and tools to deploy them to 5G networks worldwide,” said Matt Garman, Vice President of Sales and Marketing, AWS.
“In collaboration with AWS, SK Telecom has successfully integrated private 5G and edge cloud. By leveraging this new technology, we will lead the efforts to create and expand innovative business models in game, media services, logistics, and manufacturing industries,” said Ryu Young-sang, President of MNO at SK Telecom.
SK Telecom and AWS also report that they have been working to improve operational stability of autonomous robots and efficiency in remote monitoring and control. Together with Woowa Brothers, the operator of food delivery app ‘Baedal Minjok,’ the two companies have completed tests of applying the 5G MEC service to outdoor food delivery robot Dilly Drive. Meanwhile, work continues with local robotics company Robotis to test run autonomous robots in the 5G cloud environment.
SK Telecom and AWS have also signed an agreement with Shinsegae I&C and Maxst to build an AR navigation and guidance system in the Coex Starfield shopping mall in Seoul. They are also working on potential use of the 5G cloud service with Deep Fine, an AR glass solution developer, and Dabeeo, a spatial recognition service provider. With the National IT Industry Promotion Agency (NIPA), SK Telecom has launched an open lab to develop realistic contents optimized for the 5G network and to support the growth of the related ecosystem.
Collaboration is also ongoing with Looxid Labs, a provider of real-time analysis for eye-gaze tracking and brain wave data, to develop services on the 5G MEC for a senior citizen center in Busan.
SK Telecom and AWS are also cooperating in the area of non-face-to-face services as demand grows due to the COVID-19 pandemic. The two companies have been working with video conferencing services provider Gooroomee to develop an environment where 2-way video conferencing and remote education services are provided without delay, and claim they have achieved a service with a latency of less than 100 milliseconds for multiple simultaneous sessions.
