NTT DOCOMO successful outdoor trial of AI-driven wireless interface with 3 partners
NTT DOCOMO has successfully executed the world’s premier outdoor field trial of real-time transceiver systems leveraging artificial intelligence (AI)-driven wireless technology, a critical advancement for sixth-generation (6G) mobile communications (AKA IMT 2030).
Conducted in collaboration with parent company NTT, Inc. (NTT), Nokia Bell Labs, and SK Telecom Co., Ltd, the field trials were held across three sites in Yokosuka City, Kanagawa Prefecture. The results validated that the application of AI optimized system throughput (transmission speed), achieving up to a 100% improvement over conventional, non-AI methods under identical environmental conditions, effectively doubling communication speeds.
Wireless communication quality can be compromised by fluctuations in radio propagation environments, leading to unstable connections. To mitigate this challenge, the partners developed “AI-AI technology,” which applies AI to both the transmitting and receiving ends of the wireless interface. This system dynamically optimizes modulation and demodulation schemes based on prevailing radio conditions, facilitating stable communication across diverse use cases. The efficacy of this technology had previously been confirmed in indoor environments.
The recent field trials aimed to verify the technology’s stable performance in complex outdoor settings, where radio conditions are subject to greater variability from factors such as temperature, weather, and physical obstructions.
This innovative AI wireless technology was evaluated across three distinct outdoor courses with varying propagation conditions, including the presence of obstacles and terminal mobility:
- Course 1: A public road featuring gentle curves, with a test vehicle traveling up to 40 km/h.
- Course 2: An environment with partial signal obstructions.
- Course 3: A road with minimal obstructions, with a test vehicle traveling up to 60 km/h.
In all test scenarios, the technology demonstrated its ability to compensate for signal degradation, confirming enhanced communication speeds. Specifically, in the highly complex propagation conditions of Course 1, the AI-AI technology yielded an average throughput improvement of 18% and a maximum increase of 100% compared to traditional methods.
These findings enable higher-speed data transmission for users and allow network operators to enhance spectrum efficiency and deliver superior quality of service (QoS). The successful outdoor validation marks a significant milestone toward the practical implementation of 6G systems, which promise a combination of high wireless transmission efficiency and reduced power consumption. NTT DOCOMO remains committed to refining this technology under a wide range of conditions and accelerating R&D efforts toward 6G realization, while simultaneously collaborating with global partners on 6G standardization (in 3GPP and ITU-R WP5D) and deployment.
This new technology will be featured at the NTT R&D FORUM 2025 hosted by NTT, scheduled from November 19–21 and November 25–26, 2025.
These three AI-wireless field trials represent the latest joint effort stemming from the collaborative AI research partnership of DOCOMO, parent NTT, Nokia Bell Labs, and SK Telecom Co, which was established at Mobile World Congress (MWC) in February 2024.
NTT Docomo has forged additional 6G alliances with a range of partners, including Ericsson, domestic Japanese suppliers Fujitsu and NEC, and testing specialists Keysight Technologies and Rohde & Schwarz.
This year has seen an increase in partnerships among Korean and Japanese operators. Earlier this month, KDDI‘s research partnership with Nokia Bell Labs was announced, focusing on achieving 6G energy efficiency and enhanced network resilience. Samsung and SoftBank entered into a memorandum of understanding (MoU) last month to co-develop prospective next-generation technologies, encompassing 6G, AI-driven Radio Access Networks (AI RAN), and Large Telecom Models (LTMs).
In a separate MoU signed in March, KT‘s and Samsung’s collaboration was formalized to jointly advance 6G antenna technology. Additionally, KT has maintained a separate research engagement with Nokia centered on semantic communications research.

SK Group and AWS to build Korea’s largest AI data center in Ulsan
Amazon Web Services (AWS) is partnering with the SK Group to build South Korea’s largest AI data center. The two companies are expected to launch the project later this month and will hold a groundbreaking ceremony for the 100MW facility in August, according to state news service Yonhap.
Scheduled to begin operations in 2027, the AI Zone will empower organizations in Korea to develop innovative AI applications locally while leveraging world-class AWS services like Amazon SageMaker, Bedrock, and Q. SK Group expects to bolster Korea’s AI competitiveness and establish the region as a key hub for hyperscale infrastructure in Asia-Pacific through AI initiatives.
AWS provides on-demand cloud computing platforms and application programming interfaces (APIs) to individuals, businesses and governments on a pay-per-use basis.The data center will be built on a 36,000-square-meter site in an industrial park in Ulsan, 305 km southeast of Seoul. It will be powered by 60,000 GPUs, making it the country’s first large-scale AI data center.
The facility will be located in the Mipo industrial complex in Ulsan, 305 kilometers southeast of Seoul. It will house 60,000 graphics processing units (GPUs) and have a power capacity of 100 megawatts, making it the country’s first AI infrastructure of such scale, the sources said.
Ryu Young-sang, chief executive officer (CEO) of SK Telecom Co., had announced the company’s plan to build a hyperscale AI data center equipped with 60,000 GPUs in collaboration with a global tech partner, during the Mobile World Congress (MWC) 2025 held in Spain in March.
SK Telecom plans to invest 3.4 trillion won (US$2.49 billion) in AI infrastructure by 2028, with a significant portion expected to be allocated to the data center project. SK Telecom- South Korea’s biggest mobile operator and 31% owned by the SK Group – will manage the project. “They have been working on the project, but the exact timeline and other details have yet to be finalized,” an SK Group spokesperson said.

The AI data center will be developed in two phases, with the initial 40MW phase to be completed by November 2027 and the full 100MW capacity to be operational by February 2029, the Korea Herald reported Monday. Once completed, the facility, powered by 60,000 graphics processing units, will have a power capacity of 103 megawatts, making it the country’s largest AI infrastructure, sources said.
SK Group appears to have chosen Ulsan as the site, considering its proximity to SK Gas’ liquefied natural gas combined heat and power plant, ensuring a stable supply of large-scale electricity essential for data center operations. The facility is also capable of utilizing LNG cold energy for data center cooling.
SKT last month released its revised AI pyramid strategy, targeting AI infrastructure including data centers, GPUaaS and customized data centers. It is also developing personal agents A. and Aster for consumers and AIX services for enterprise customers.
Globally, it has found partners through the Global Telecom Alliance, which it co-founded, and is collaborating with US firms Anthropic and Lambda.
SKT’s AI business unit is still small, however, recording just KRW156 billion ($115 million) in revenue in Q1, two-thirds of it from data center infrastructure. Its parent SK Group, which also includes memory chip giant SK Hynix and energy firm SK Innovation, reported $88 billion in revenue last year.
AWS, the world’s largest cloud services provider, has been expanding its footprint in Korea. It currently runs a data center in Seoul and began constructing its second facility in Incheon’s Seo District in late 2023. The company has pledged to invest 7.85 trillion won in Korea’s cloud computing infrastructure by 2027.
“When SK Group’s exceptional technical capabilities combine with AWS’s comprehensive AI cloud services, we’ll empower customers of all sizes, and across all industries here in Korea to build and innovate with safe, secure AI technologies,” said Prasad Kalyanaraman, VP of Infrastructure Services at AWS. “This partnership represents our commitment to Korea’s AI future, and I couldn’t be more excited about what we’ll achieve together.”
Earlier this month AWS launched its Taiwan cloud region – its 15th in Asia-Pacific – with plans to invest $5 billion on local cloud and AI infrastructure.

WSJ: 5G in South Korea has not lived up to expectations
Four years ago, South Korea led the world’s biggest rollout of 5G, promising a huge increase in network speeds that would help usher in a flurry of new technologies such as autonomous cars, augmented reality and remote surgeries. South Koreans are still waiting for that to happen.
In 2022, South Korea’s average 5G download speed was 896Mbps -roughly six times that of the country’s average 4G download speed and more than double the 5G speeds of the United Arab Emirates and the U.S., according to the Korea Telecommunications Operators Association, a trade group. Despite those achievements, the network has fallen short of what was promised.
South Korea’s three major mobile carriers—SK Telecom, KT, and LG Uplus—advertised speeds up to 20 times faster than 4G LTE as they rolled out the new service, one of the world’s first commercial 5G networks, in April 2019. But, so far, such speeds can be achieved only on localized networks with limited coverage, and aren’t being pursued for wider use. Many consumers in South Korea were left underwhelmed by the minor improvements in speed and spotty connections. The network’s quality and speed have since improved with technologies such as “standalone 5G” (5G SA) that runs on its own network infrastructure rather than relying in part on those of 4G. Still, subscriber growth for 5G service has been slower than it was for 4G, and many of the visionary services talked about in the country haven’t come around.
South Korea’s nationwide 5G network experience has improved since the new network’s introduction, and driven more data usage. But technical hurdles and cost constraints have limited the ability to offer on a wide scale the type of 5G capable of even faster speeds, according to industry analysts and some of the South Korean carriers themselves.
Some of the difficulties stem from the frequencies at which radio waves travel. Countries around the world have enabled their 5G networks on different frequency bands, with most choosing low- or mid-frequency bands. South Korea’s main telecom firms developed their public 5G networks on the 3.5-gigahertz band, a mid-frequency band.
At the same time, 5G can be enabled on the high-frequency bands supporting millimeter wave, the type touted at 5G’s inception that can provide more-extreme boosts in speed. But a significant downside is that millimeter waves don’t travel well across long distances and through obstacles such as trees, buildings and glass. Thus, networks with the highest speeds are more challenging and expensive to deploy at scale.
South Korean telecom firms chose not to use the 28-gigahertz band, a high-frequency band supporting millimeter waves, in deploying nationwide 5G networks. Under this network environment, the latest smartphones currently sold in the country also do not come with the antenna system supporting this band.
The three telecom firms recently lost their licenses for the 28-gigahertz band after they didn’t meet the mandatory set number of 5G base stations using that band that needed to be built in order to keep the licenses. Now, the government is looking to grant 28-gigahertz licenses to nontelecom entities looking to use the band for 5G services in locations they deem as fit.
In May, South Korea’s Fair Trade Commission collectively fined the country’s three carriers about $24.8 million for allegedly using misleading advertising that exaggerated the speed of their 5G networks at their launch. The promoted speeds were a target that couldn’t be achieved in everyday usage environments, the South Korean FTC said in its decision.
South Korea’s apparent retreats in millimeter-wave 5G development put the country’s 5G leadership at risk, says a recent report from OpenSignal, a mobile-analytics company that monitors and analyzes the global telecom industry.
- LG Uplus says that the 28-gigahertz band’s properties made it costly and technologically difficult to deploy at a mass scale, and that the company would continue to work on improving the quality of its 5G services.
- SK Telecom says it will continue improving its 5G services, though it notes that South Korea boasts the world’s top 5G services in terms of speed and coverage and that consumers are using more data at lower costs.
- KT declined to comment.
This doesn’t mean the millimeter-wave band has lost its commercial appeal. Today, it is being used around the world—albeit in only a handful of cases—to enable ultrafast 5G in a fixed area, such as a sports arena, airport or smart factory, industry analysts say. Major telecom operators in the U.S. and Japan are using high-frequency mmWave bands for Fixed Wireless Access (FWA) or as one of the ways of enabling their 5G networks in dense urban locations, though coverage made available through these bands is limited to small areas and line of sight communications.
In South Korea, meanwhile, the 28-gigahertz band is being used to support some private 5G networks serving specific needs. One network, for example, supports autonomous robots at a local tech company and another assists augmented-reality technologies in surgery. Special licenses were issued in both cases. The 28-gigahertz band also is being used inside parts of Seoul’s subways, a government-led project that involved the three telecom companies. But whether that network will continue to operate, given the revocation of the three carriers’ 28-gigahertz licenses, remains to be seen.
At its beginnings, 5G was touted as a technology that would usher in a new era of smart cities, autonomous driving and holograms. But even in South Korea, where 5G adoption is higher than elsewhere, those new services are being pursued but haven’t taken off widely. Low market demand, the limited availability of devices that would support 5G as well as regulatory barriers all made it difficult for related services to go mainstream, said SK Telecom, the largest of South Korea’s three telecom firms, in a rare 6G white paper that outlined some key takeaways from 5G.
That is partly a chicken-and-egg problem, says Julian Gorman, head of Asia-Pacific for GSMA, a trade association for mobile carriers. Developers are often reluctant to invest in new products for a developing technology like 5G, especially the type using millimeter waves on the high-frequency bands. In turn, telecom providers see a weaker business rationale for investing aggressively in widespread millimeter-wave 5G coverage, he says.
The usage scenarios presented at 5G’s inception were more of a demonstration of the technology rather than solid proof that there was a business need to do so, Gorman says, adding that the 5G ecosystem is still trying to determine what types of new services and technologies are wanted in the market.
The lack of 5G killer apps also feeds into a bigger trend: 5G has been a harder sell than 4G. That’s mainly because URLLC does not meet the advertised ITU-R M.2410 performance requirements. So there are no mission critical, ultra low latency/real time applications that can use 5G.
In South Korea, the number of 5G subscribers surpassed 30 million in April this year, roughly four years after 5G’s initial introduction. But with 4G, that same milestone was reached after about 2½ years, according to data from the Ministry of Science and ICT (information and communication technology).
That is a trend echoed globally as well. As of 2022, about 32% of smartphones in circulation worldwide were 5G-capable, but just 45% of those phones were activated on a 5G network, down from 55% a year earlier, according to Omdia. This partly shows that more people are upgrading to 5G phones without necessarily choosing a 5G plan, in addition to 5G not being available yet in some places, it said.
“People are simply not ready to pay more for 5G, because they’re totally content with 4G,” which many consider sufficient for doing things like streaming video, says De Renesse of Omdia. “Many still ask, why would I pay more for doing the same thing?” he says.

South Korea’s antitrust regulator said it had imposed a total of 33.6 billion won ($25.06 million) in fines on three domestic mobile carriers for exaggerating their 5G network speeds. The Korea Fair Trade Commission (KFTC) said the three South Korean firms – SK Telecom Co Ltd, KT Corp, and LG Uplus Corp – had also unfairly advertised that they were the fastest relative to their competitors.
“The three telecom companies advertised that consumers could use target 5G network speeds, which cannot be achieved in real-life environment … companies advertised that their 5G network speed was faster than competitors without evidence,” the KFTC said in a statement.
In support of ongoing civil lawsuits filed by consumers, the advertisements released by the three mobile carriers have been presented by the regulator to a local court.
SK Telecom and KT Corp declined to comment. A spokesperson at LG Uplus said the company is reviewing the sanctions.
The KFTC imposed a fine of 16.8 billion won on SK Telecom, 13.9 billion won on KT and 2.8 billion won on LG Uplus.
There were 30.76 million 5G network users in South Korea in June, accounting for about 38% of the total 80.23 million mobile subscriptions in the country, according to data from the Ministry of Science and ICT.

In a paper issued last week, SK Telecom states correctly the industry is far from achieving its 5G goals even four years after commercialization. There were “misunderstandings” about network performance and problems such as device form factors and lack of market demand, it said. “A variety of visionary services were expected, but there was no killer service,” the paper stated. “We should have taken a more objective perspective,” it added. In particular:
A variety of visionary services were expected, but there was no killer service Even at the time when preparing for 5G, services such as autonomous driving, UAM, XR, hologram, and digital twin had appeared and expected, but most of them did not live up to expectations. We should have taken a more objective perspective. For example, whether 5G technology alone could change the future, or whether the overall environment constituting the service was prepared together. If so, the gap between the public’s expectations for 5G and the reality would not have been large. 3D video, UHD streaming, AR/VR, autonomous driving, remote surgery, etc. are representative services that are not still successful presented by the 5G Vision Recommendation. Most of them are the result of a combination of factors such as form factor constraints, immaturity of device and service technology, low or absent
market demand, and policy/regulation issues, rather than a single factor of the lack of 5G performance.
The authors concluded that instead of expecting that the new technology alone could create successful services, it would have been more effective to have collaborated with partners to build a broader 5G ecosystem.
Gap between 5G Vision Recommendations and customer expectations:
Although the usage scenarios and capability goals presented in the 5G Vision Recommendation are future goals to be achieved in the long term, misunderstandings have been created that can lead to excessive expectations of 5G performance and innovative services based on it from the beginning of commercialization. To prevent this misunderstanding from recurring in 6G, it is necessary to consider various usage scenarios of 6G, set achievable goals, and communicate accurately with the public. In particular, there were issues raised about the maximum transmission speed of 20Gbps, which was considered an icon of 5G key performance indicators. As 3G evolved into LTE, the radio access technology also evolved from WCDMA to OFDMA, and with the introduction of CA and multi-antenna technology, it became possible to use a much wider bandwidth than 3G. This can be seen as a ‘revolutionary’ improvement. On the other hand, 5G is considered as an ‘evolutionary’ improvement that supplements the performance of LTE based on the same radio access technology, CA, and multi-antenna system technology. Due to this, it was difficult to implement the increase in transmission speed shown in LTE in 5G at once. Moreover, the difference in technology perception was further revealed in the initial stage of 5G commercialization. Early commercialization was promoted for 5G, however, 5G required more base station compared to LTE to build a nationwide network due to frequency characteristics, requiring more efforts in terms of cost and time.
SK Telecom has made significant efforts to expedite 5G nationwide rollout, but customers wanted the same level of coverage as LTE in a brief period.

South Korea has 30 million 5G users, but did not meet expectations; KT and SKT AI initiatives
South Korea is arguably one of the leading countries that has deployed 5G. According to the Ministry of Science and ICT, the country had 29.6 million users as of this March, and given that number of subscribers has increased to around 500,000 per month up to now, it is more than likely that as of early May, there are 30 million 5G users. This milestone comes four years after 5G became available in smartphones in the country in April 2019 (based on 3GPP Release 15 specs).
South Korea started 2G code division multiple access (CDMA) services in 1996 and 3G wide CDMA in 2003, starting the cell phone era. This allowed South Korean telecommunication companies to expand abroad. The launch of WCDMA also allowed Qualcomm and Samsung to become leaders in application processors and smartphones, respectively, today. Then in 2011 came 4G long-term evolution (LTE) services. This truly enabled smartphones which could now stream videos in real time. South Korean wireless network operators SK Telecom, KT and LG Uplus became board members of GSMA, the global telecommunications suppliers organization.
Expectations were high for 5G. The government and telcos claimed in marketing before launch that 5G will be, compared to 4G, 20 times faster, 100 times better simultaneous access and 10 times shorter delays. They claimed new augmented reality, virtual reality, 3D content and IoT services would be introduced. However, the reality after 5G launched was quite different and none of the promises were kept.
According to the Ministry of Science and ICT, 5G download speed on average was 896.10Mbps as of October. Upload speed was on average 93.16Mbps. This was only faster by 5.9 times and 2.8 times faster, respectively than 4G LTE in the same month.

5G coverage was also only around 33.1% of the country, which means on a national level, most people were using non-standalone 5G services (5G NR with LTE infrastructure and EPC).
Spending to obtain 28 GHz mmWave spectrum has effectively ended. KT and LG Uplus had their spectrum cancelled in December; SK Telecom is also expected to lose theirs within the year (SEE UPDATE BELOW)! Without spending on 28GHz, there will be no “20 times faster 5G.” The country’s Fair Trade Commission is expected to penalize the three South Korean telcos for violating advertisement laws.
………………………………………………………………………………………………………………………………………………………………………………..
On the positive side, 5G is being combined with AI. KT announced the commercial launch of a new solution, which it calls its “5G Infrastructure Intelligent Control Solution”, that is based on artificial intelligence (AI) technology. The South Korean network operator noted that this solution is designed to control 5G infrastructure with the aim of making that infrastructure more efficient and stable.
KT’s new solution is equipped with AI technology to detect abnormalities in the status of networks and equipment in real-time. By comparing dozens of equipment quality data in real-time with pre-learned data, the new solution can determine whether the equipment is abnormal or not with a single indicator, KT said. Also, the solution also displays the status of access and core equipment in five stages, making it easy to “intuitively check the equipment and the degree of abnormality” that occurred, the Korean telco added.
The company highlighted that companies and institutions without expertise in network management can use KT’s 5G solution to operate 5G networks without any “burden.” KT said it has already implemented the solution in four institutions, including Bundang Seoul National University Hospital, Samsung Seoul Hospital, Korea Aerospace Industries Co., Ltd. and Navy Headquarters.
“When KT’s 5G specialized network testbed is established, it will be possible to perform a one-stop service for testing equipment for 5G specialized network, interworking with terminals, and conducting network trial operation and inspection. It is expected to greatly reduce the cost and technical burden of companies considering the introduction of a 5G specialized network,” KT said.
“SK Telecom (SKT) is stepping up efforts on all fronts to transform itself into an AI company,” CFO Kim Jin Won told a results briefing Wednesday. Its strategy is to grow through partnerships with local and global top-tier AI companies while also continuing to develop its own AI technology.
SKT has been trialing generative AI in its A. (pronounced “A-dot”) service, built on its own technology and capable of holding complex conversations and developing long-term memories. Last month the telco invested 15 billion Korean won (US$11.4 million) in local startup Scatter Lab, which has used deep learning to create a chatbot that can hold empathetic conversations. SKT wants to work with Scatter Lab to develop an AI agent that can have human-like conversations with A. customers. The two companies also aim to develop a hyperscale language model equipped with emotions and knowledge domains.
May 15 2023 Update:
On Friday, May 12th South Korea’s Ministry of Science and ICT cancelled SKT’s 28 GHz 5G license. The Korean network operator’s major rivals KT Corp and LG U+ had their 28 GHz licences cancelled last year for the same reason, but SKT held on to its concession by the skin of its teeth and escaped with a warning.
“It is regrettable that this result has finally come about despite the government’s active efforts so far,” said Choi Woo-hyuk, director of radio wave policy at the Ministry of Science and ICT, in a Korean language statement confirming the licence withdrawal.
The three South Korean mobile operators each acquired 800 MHz of 28 GHz spectrum, alongside 3.5 GHz frequencies, in 2018, with the band being available for use by the end of that year. The licence conditions required them to deploy 15,000 base stations using 28 GHz within three years. But an investigation on the part of the last year Ministry showed that the telcos had built only 10% of the number of sites they had committed to, which led to it pulling the licences of the worst offenders: KT and LG U+.

3 South Korean mobile operators to share 5G networks in remote areas
SKT Develops Technology for Integration of Heterogeneous Quantum Cryptography Communication Networks
SK Telecom (SKT) today announced that for the first time in the world, it developed a technology that allows for integrated control and operation of quantum cryptography networks by integrating networks composed of equipment from different manufacturers via software-defined networking (SDN) and distributing quantum keys in an automated manner.
So far it was impossible to connect and operate quantum cryptography communication networks of different companies and countries. However, with SKT‘s new technology, quantum cryptography communication networks of diverse manufacturers, mobile operators and nations can be interconnected and co-operated.
The company said that it completed verification of the technology on the Korea Advanced Research Network (KOREN), a non-profit testbed network infrastructure operated by the National Information Society Agency (NIA) to facilitate research, test and verification of future network leading technologies and related equipment.
Based on the results of development and verification of the technology, SKT has been actively promoting standardization by sharing the case with global telcos.
To set international standards for the integration of quantum cryptography communication networks, SKT proposed two standardization tasks – i.e. ‘Control Interface of Software Defined Networks’ and ‘Orchestration Interface of Software Defined Networks for Interoperable Key Management System’ – to the European Telecommunications Standards Institute (ETSI), and they were chosen as work items by the ETSI industry specification group for QKD (ISG-QKD) in March 2023.
If approved as international standards, they will provide a technical basis for creating a large-scale network by interconnecting quantum cryptography communication networks built by many different operators. SKT plans to continue developing additional technologies for interworking of services between different operators/countries, as well as management of service quality.
Through these efforts, the company expects to strengthen the competitiveness of domestic companies and boost the quantum cryptography ecosystem both home and abroad.
Meanwhile, at this year’s IOWN Global Forum Workshop, SKT presented ‘Quantum Secure Interconnection for Critical Infrastructure,’ covering use cases for next-generation transmission encryption technology and proposal for a proof-of-concept (PoC) of quantum cryptography in All-Photonics Network (APN). The company also showcased its quantum cryptography communication technologies at 2023 MWC Barcelona.
“The two standardization tasks approved as work items by ETSI will boost the expansion of quantum cryptography communication in the global market,” said Ha Min-yong, Chief Development Officer of SKT. “We will work with diverse global players in many different areas to create new business opportunities in the global market.”

From SDxCentral:
Quantum cryptography communication transmits each bit of information as a single photon of light, which encrypts that information against eavesdropping or decryption. Telecom operators and vendors have been working for several years on integrating that level of encryption into networks.
For instance, Toshiba and the Tohoku Medical Megabank Organization at Tohoku University used quantum technology in 2018 to hit one-month-average key distribution speeds exceeding 10 Mb/s over installed optical fiber lines. They also used the technology to monitor the performance of installed optical fiber lines in different environments.
Toshiba later partnered with U.K.-based operator BT on using QKD across to secure a network transmission.
SK Telecom also has a long quantum history, including work with Swiss-based strategic partner ID Quantique, which focuses on quantum cryptography communication technology.
Industry trade group GSMA last year announced its Post-Quantum Telco Network Taskforce focused on supporting the industry’s creation of a roadmap to secure networks, devices and systems across the entire supply chain.” That work was initiated with IBM and Vodafone, and has since gained more than 45 members.
Lory Thorpe, GSMA Post-Quantum Telco Networks chairperson and head of IBM Consulting’s Telco Transformation Offerings, told SDxCentral last month that the core objective of the taskforce is to ensure the implementation of the right requirements and standards in a timely manner to avoid being “late to the party.” Thorpe explained the initial problem statement was “around how do we support the telco ecosystem to navigate the path to quantum safe.”
“When you look at where cryptography is used in telco systems, it impacts basically all of the different systems. But it also then impacts all of the standards that underpin these systems as well,” she said. “We’re advocating that people start planning, not panicking, but at least planning because … this isn’t something that just happens overnight.”
SK Telecom inspects cell towers for safety using drones and AI
SK Telecom, South Korea’s largest wireless carrier, announced on Tuesday that it’s developed a new cell tower safety inspection system using drones and image analysis artificial intelligence (AI). The newly-developed image analysis AI model checks the status of nuts and bolts by analyzing images taken by drones.
Cell towers with antennas for sending and receiving telecommunications signals are installed across the country, with their maximum height estimated at 75 meters. Since cell towers require regular maintenance to prevent accidents that can be caused by deterioration such as corrosion or loosening of nuts and bolts, specialized personnel had to climb them to inspect their condition with their bare eyes.

Now with an intelligent safety inspection system in place, not only can SK Telecom prevent accidents due to aging cell towers, but it can also ensure the safety of workers by minimizing the need to go up the cell towers. Moreover, the company can drive up work productivity through the application of an AI model that automatically identifies defects by analyzing images taken by drones.
Previously, safety inspectors had to study around 100 images to complete the inspection of one cell tower by inspecting multiple images taken by drones. With the adoption of the new AI analysis model, SK Telecom has been able to reduce the time required for the process by 95%, while increasing the reliability and consistency of the analysis results.
The company says, going forward, it will enhance the system even further by adding inspection items such as wind pressure safety/inclination. It will also look to improve the AI model and link the application with the safety management system.
In addition to drone-based cell tower inspections, the telecom company is actively applying AI to other areas of its network, including equipment error/anomaly detection, power cost reduction, and work completion inspection.
Park Myung-soon, SKT’s vice president and head of Infra DT Office, said: “By building an intelligent safety inspection system that can complement the existing visual inspection, we have secured greater safety for workers. We will continue to make efforts to achieve AI transformation of our telecommunication networks, while focusing on developing our field workers into experts who can develop and operate AI.”

SK Telecom launches its metaverse platform ‘ifland’ in 49 countries and regions
SK Telecom (“SKT”) today announced that its metaverse platform ‘ifland’ simultaneously launched in 49 countries and regions throughout the world. With the global launch of ifland, SKT will actively utilize K-pop content, develop attractive content with overseas partners, and strengthen communication features to shape ifland into a global leading social metaverse platform.
The global version of ifland supports English, Chinese (Traditional Chinese, Simplified Chinese) and Japanese, and is available for both Android and iOS smartphone users. The existing ifland app will be upgraded to the new global version. For instance, the app will automatically activate in the Korean mode when accessed from Korea, and the global mode when accessed from overseas countries.
This global expansion of ifland comes after SKT launched its existing Korean language service in July 2021. Since then, it has experienced 8.7 million downloads in its first year of operation. As of October 2022, Ifland had 12.8 million users.
Under the slogan, “The New Way of Socializing,” ifland will deliver a differentiated communication experience within the metaverse.
SKT will effectively expand ifland’s global reach through partnerships with major telecommunications companies in each continent. The company is working with e& (formerly known as Etisalat Group) in the Middle East, Africa and Asia, and Singtel in South East Asia.
On November 18, 2022, SKT signed a memorandum of understanding (MOU) with NTT Docomo, the largest mobile operator in Japan, to cooperate in areas of content, technology and service to further advance their metaverse services. Through the MOU, the two companies will forge strategic partnership in three key areas –metaverse, mobile network infrastructure and media business. They will also create greater synergies by cooperating with other SK ICT affiliates like SK Hynix and Contents Wavve (a joint venture between Korean terrestrial broadcasters KBS, MBC, and SBS and SKT).
First, SKT and NTT DOCOMO will work together in the areas of content, technology and service to further advance their metaverse services. SKT has been operating its metaverse service ‘ifland’ since July 2021, while NTT DOCOMO launched its metaverse service in March 2022.
Partnership discussions with other telecommunications companies are also underway. Together with its overseas partners, SKT plans to develop specialized features tailored to each different region. They will also promote various metaverse-related events and business cooperation, including joint production of popular local content.

Moreover, SKT plans to offer content targeting the “MZ generation (Millennials and Generation Z)” through partnerships with diverse players including overseas universities and international brands.
Early this month, SKT signed a memorandum of understanding (MOU) with Thailand’s Bansomdejchaopraya Rajabhat University (BSRU) and Korea’s Dong-ah Institute of Media and Arts (DIMA) – which is providing a variety of programs including ‘Teen Teen Audition’ in ifland since the beginning of this year – to create a global metaverse campus. SKT will actively support BSRU and DIMA to overcome the limitations stemming from the physical distance between the two schools through ifland.
In addition, the company is working with Birger Christensen, a Copenhagen-based fashion company with over 150 years of history, to launch digital skins for avatars in ifland within this year to enable the MZ generation to better express themselves.
SKT has also updated key features of ifland. The company opened a global lounge within ifland to help those new to the metaverse to experience the new world with greater ease, and introduced avatars of many different colors.
In addition, to facilitate communication between hosts and participants of gatherings in ifland, SKT applied features like ‘one-on-one direct messaging’ and ‘3D speech bubble.’ ‘Live voting’ feature was also introduced to check the opinions of participants in real time, and ‘ifme motion sharing’ feature was adopted to apply the user’s facial expressions to his/her avatar.
To celebrate the global launch of ifland, SKT will be showcasing a wide variety of live K-pop content every week. Original metaverse K-pop content titled “The Fan Live Talkon” will target K-pop fans overseas, with over 50% of content provided in English. Every week, ifland will offer live content related to K-pop – e.g. auditions for K-pop trainees and nurturing of K-pop idols – for global fans to enjoy.
Within this year, through ifland’s SNS account, SKT plans to hold events to give out diverse artists’ goods and gifts to overseas users who participate in the meet-ups of K-pop content.
Meanwhile, ifland has surpassed 12.8 million of cumulative users as of October 2022, which represents a four-fold increase compared to 3 million early this year thanks to differentiated content offerings like original metaverse content.
“Since its launch in Korea in July 2021, ifland has grown rapidly to become the best social metaverse in Korea by attracting users of diverse age groups as well as many different organizations,” said Yang Maeng-seok, Head of Metaverse Office at SKT. “Now, we will go beyond Korea to expand our reach in the global market to take customers metaverse experience to the next level.”
List of countries in which ifland launched:
Argentina, Azerbaijan, Belgium, Brazil, Cambodia, Canada, Chile, Denmark, Deutschland, Finland, France, Ghana, Greece, Hong Kong, India, Indonesia, Ireland, Italy, Japan, Jordan, Kenya, Lebanon, Macau, Malaysia, Mexico, Myanmar, New Zealand, Norway, Palau, Poland, Portugal, Qatar, Rwanda, Singapore, Spain, Sri Lanka, Sweden, Switzerland, Taiwan, Thailand, the Dominican Republic, the Netherlands, the Philippines, the United Arab Emirates, the United Kingdom, the United States, Tunisia, Turkey, Vietnam

SK Telecom, Samsung, HPE and Intel MOU for 5G NFV Technology Evolution; ETSI ISG-NFV?
Who needs the ETSI ISG on NFV? Apparently, no one BUILDING 5G INFRASTRUCTURE! Founded in November 2012 by seven of the world’s leading telecoms network operators, ETSI ISG NFV became the home of the definition and consolidation for Network Functions Virtualization (NFV) technologies. Yet there is very little, if any, commercial deployments based on their specifications. In particular, the greatly promoted ETSI NFV management and orchestration (NFV-MANO).
SK Telecom today announced that it signed a Memorandum of Understanding (MOU) with Samsung Electronics, Hewlett Packard Enterprise (HPE) and Intel for cooperation in the commercialization of an evolved 5G network functions virtualization (NFV) platform.
Under the MOU, the four companies will jointly develop evolved NFV technologies for 5G network infrastructure, establish a standardized process for adoption of NFV, and develop technologies that can harness the capabilities of the virtualized network. Together, the companies will be able to reduce the time required to validate and integrate technologies from various vendors as well as verify them within the network. This will result in a more rapid introduction of new innovative technologies that enhance end user experience.
Mobile operators will be able to benefit from a significantly reduced time-to-market for the latest 5G services such as augmented reality (AR) and virtual reality (VR) through the NFV platform. Previously, they had to install each new hardware equipment or upgrade existing ones to introduce a new service.
The four companies will realize an evolved 5G NFV platform by applying Samsung’s 5G solution based on technologies from Intel and HPE to SK Telecom’s 5G network. To this end, Intel will provide its latest technologies, including Intel Xeon Processors, Ethernet 800 Series Network Adapters and Solid State Drives, and HPE will provide HPE ProLiant Servers to Samsung Electronics for early development and verification purposes. SK Telecom plans to establish a process for 5G network virtualization, which includes interconnecting its 5G core network to Samsung’s virtualized 5G solutions.
“Through this global cooperation, we will secure a solid basis for commercialization of an evolved 5G NFV platform and provide more innovative services to our customers,” said Kang Jong-ryeol, Vice President and Head of ICT Infrastructure Center of SK Telecom. “Going forward, we will continue to develop new technologies for 5G NFV evolution to play a leading role in realizing communication services of the future.”
“Together with SK Telecom, HPE and Intel, Samsung will lay the groundwork for network virtualization to allow SK Telecom to swiftly apply Samsung’s virtualized solutions on partner hardware platforms. As more operators look to virtualized networks, this collaboration will serve as an exemplar of transforming legacy networks to virtual networks,” said Roh Wonil, Senior Vice President and Head of Product Strategy, Networks Business at Samsung Electronics. “With proven success in 5G commercialization, we will continue to extend our 5G leadership, allowing customers to experience immersive 5G services.”
“Industry collaboration is essential to accelerate the rollout of 5G networks,” said Dan Rodriguez, corporate vice president and general manager of the Intel Network Platforms Group. “The joint work between SK Telecom, Intel, HPE and Samsung will be instrumental in helping SK Telecom implement the latest technologies and new capabilities in a faster and more agile way, ultimately delivering new innovative services to their end users.”
“We are pleased to be providing telco optimized infrastructure for this collaboration with SK Telecom, Samsung and Intel”, said Claus Pedersen, vice president, Telco Infrastructure Solutions, HPE. “HPE believes that the future of 5G lies in open, interoperable software and hardware innovation from different vendors. This is yet another proof point that HPE is the leading open infrastructure provider for 5G, helping telcos to deploy 5G services faster, on secure telco optimized platforms.”
