NEC announces successful transmission of live 8K video using 5G

In conjunction with France’s largest television station, France Televisions, NEC successfully transmitted footage of the recent French Grand Slam tennis tournament at Roland-Garros.

The demonstration used NEC’s VC-8900 8K material transmission encoder to transmit high-definition live 8K video of the tournament to 8K video monitors and 5G smartphones and tablets at a location within the tournament’s venue.

The NEC’s VC-8900 8K material transmission encoder utilises real-time video compression technologies to make it possible, along with the use of high-bandwidth 5G technology.

Significant step forward

It’s a significant step for the future of how we’ll consume live television with 8K the natural step following 4K footage. It also builds upon NEC’s efforts last January which had them working together with Japanese telecommunications firm NTT DOCOMO and Tobu Railway, where they conducted video transmission tests through 5G base stations that support 4.5GHz and 28GHz bands.

In this case, the test used an 8K live video sample of a steam locomotive transmitted from a 5G base station installed along the railroad tracks to a 5G mobile station connected to an 8K display inside the moving train. It also used pre-recorded VK video content to confirm the effectiveness of 5G in the transmission of data-dense video content.

Moving from one display to multiple smartphones and tablets at Roland-Garros is a big step forward in NEC’s plan for revolutionising how we consume media in future.

“Building on the success of this initiative, NEC will further promote the realization and expansion of next-generation broadcasting services using high-definition video in 2020 and beyond,” explained Takeshi Inoue, General Manager, Broadcast and Media Division of NEC.

While no other plans have yet been announced for what NEC is set to do next, it’s clear that such tests are paving the way towards a future where 8K video footage is more readily accessible and potentially enhancing what we’re able to see when attending major events.

NEC uses 5G to contribute to remote medical examination trials


NEC Corporation today announced its contributions to field trials in remote medical examinations using 5G. NEC provided a base station system as part of comprehensive 5G demonstration experiments carried out by NTT DOCOMO, INC., the Wakayama Prefectural Government, and Wakayama Medical University and hosted by the Ministry of Internal Affairs and Communications.

Wakayama Prefecture is a mountainous, sparsely populated region of Japan, with limited access to advanced medical institutions. Moreover, the medical offices located there are often understaffed and doctors are frequently required to see patients who are outside of their expertise. Therefore, the Wakayama Prefectural Government established a remote medical support system (a video conference system that uses an Internet connection) which connects 13 prefectural medical institutions and Wakayama Medical University, allowing doctors to receive advice from specialists, even in towns in mountainous areas. However, the system frequently met with problems, including unclear images and transmission delays. 

In order to address these issues, verification tests have been conducted with an optical cable to establish a remote medical examination service utilizing 5G to connect Wakayama Medical University and Hidakagawa Kokuho Kawakami Clinic, which is about 30 km from the university. As part of this, NEC set up a massive-element Active Antenna System (AAS)base station system supporting a 28 GHz band to create a 5G wireless network.

In this experiment, large-capacity 5G transmission enabled real time communication and sharing of images taken by a 4K close-up camera, high-definition echocardiographic (echo) video and MRI images using a 4K video conference system between Wakayama Medical University and Kokuho Kawakami Clinic.

Participants included doctors from the dermatology, cardiovascular internal medicine and orthopedic surgery departments of Wakayama Medical University and its hospital. Benefits of the experiment included the use of high-definition large-screen monitors, making it possible to easily view the condition of a subject in minute detail. Further, because of the realistic feeling of the reactions and expressions during a doctor’s interview, it became possible to communicate with patients more personally, supporting the progress of the medical examinations and reducing the burden on medical staff and patients.

“Ultra-high-speed 5G communications are often associated with the entertainment industry. However, these trials showed us that 5G can play a role in solving social issues, such as reducing regional disparities in the delivery of health care. We plan to create new business models and value by continuing to take advantage of 5G technologies in collaboration with ICT vendors, and a wide variety of companies and organizations in the near future,” said Jun Mashino, Senior Research Engineer, 5G Radio Access Network Research Group, 5G Laboratory, NTT DOCOMO.

“The remote medical examinations system, where valuable advice can be delivered by medical specialists, will likely become a reliable support system for inexperienced doctors who are newly dispatched to remote areas. I also believe that the system can be utilized for providing emergency medical care, such as by using small-sized echo cameras to transmit high-speed video images of patients at disaster sites or at the site of an accident. We plan to continue improving the quality of rural medical services by proactively adopting cutting-edge technologies,” said Takashi Yamano, M.D., Ph.D, Department of Cardiovascular Medicine Community, Medical Support Center, Wakayama Medical University.

“In the field trials, it was as if the medical specialist at the prefectural medical university was right there next to me as we watched the same video of the patient’s affected area. Getting the opinion of a medical specialist provides patients with the advantage of a highly reliable examination, while the doctors are provided with the opportunity to acquire specialized knowledge. I truly hope that this kind of cutting-edge medical service spreads outside our prefecture,” said Naoki Hirabayashi, M.D., Director, Hidakagawa Kokuho Kawakami Clinic.

“In this demonstration experiment, we are honored to have contributed to the efforts to improve medical services in sparsely populated, mountainous areas by utilizing high-speed and large-capacity 5G wireless technology. We will continue to improve the performance of 5G technology and contribute to the provision of new medical services in cooperation with NTT DOCOMO and Wakayama Medical University,” said Seiji Kondo, General Manager, Wireless Access Solutions Division, NEC Corporation.

NEC’s massive-element AAS base station system adopts a fully digital control system, which improves the precision of beamforming. The fully digital control system enables simultaneous beamforming in multiple directions from a single massive-element AAS unit, which efficiently implements high-speed and high-capacity communication without interfering with adjacent users through spatial multiplexing.

NEC will continue its efforts to develop a massive-element AAS base station system that delivers high speed, high capacity, and massive connectivity, aiming for the practical use of 5G technology. As in this remote medical examination, NEC cooperates with telecommunications carriers and partners alike, aiming for the creation of new services and businesses through the utilization of 5G.

  • *This trial was conducted by NTT DOCOMO under a project commissioned by Japan’s Ministry of Internal Affairs and Communications to examine the technical specificationsfor 5th generation mobile communication systems that can realize a data communication speed exceeding 10 Gbps in densely populated areas.

Climbers to get free Wi-Fi on Mount Fuji


Following a raft of requests, free Internet access will be available on Mount Fuji starting July 10 in a bid to bring more overseas tourists to Japan’s highest peak.

Working with telecommunications carrier NTT Docomo Inc., Yamanashi and Shizuoka prefectures will set up Wi-Fi hotspots at eight locations on the mountain, including three cottages around the summit and a general management center and a resort facility at the fifth station in Yamanashi Prefecture.

The free Internet access will be available at the fifth station from July 10 through Sept. 14 and around the summit between July 10 and Sept. 10, according to the Yamanashi prefectural government.

Climbers who are extremely slow could be out of luck, however. The free Wi-Fi will be available for 72 hours from the first login.

The service will be available to all hikers, but the two prefectures are more focused on attracting climbers from overseas through e-mail and social media.

“We hope people will use the service not only to tell about the attractions of Mount Fuji to people abroad but also to obtain weather and other information to ensure their safety,” said an official at the Yamanashi prefectural government’s tourism promotion division.

Yamanashi and Shizuoka prefectures plan to distribute 70,000 brochures and special cards in foreign languages at the mountain’s fifth and sixth stations to show tourists the predetermined passwords and steps to access the Wi-Fi service.

According to Yamanashi prefectural officials, the number of overseas visitors to the mountain has been increasing every year. An estimated 40,000 to 50,000 foreign tourists hiked along the Yoshidaguchi course last year.

However, many climbers from the United States and Europe have said they wanted to use the Internet to share their experiences while on the mountain, the officials said.

Docomo, EE and Nokia stress role of LTE on path to 5G

Nokia, EE and NTT Docomo see 5G as an evolution of 4G, with many of the proposed technology changes able to be deployed alongside existing technology implementations.

Speaking at an event in London yesterday, Phil Twist, VP of networks marketing at Nokia, noted that while work on new 5G radio technology is underway, “there are as many changes that go on inside the network as there are in the new radio interface that will become 5G”.

“Actually, if 5G is in its research stage now in terms of radio, it is well beyond the research phase in terms of the network architecture and how you would need to build networks. It does build quite a different network architecture to the ones that are in service today. Because we can see this, because we know what we need to do with this, we can start working towards this type of architecture now,” he continued.

This sentiment was echoed by Mansoor Hanif, director of radio access networks for UK LTE pioneer EE. “We can and will apply many, if not all, of the 5G innovations over 4G. We will only do it when it makes sense for our customers. I think that 99 per cent of the things you see are doable over 4G. Which ones it makes sense for our customers to bring forward, that’s the key question.”

And while NTT Docomo has established a technology leadership position through its early introduction of new technologies, Sadayuki Abeta, director of the radio access network docomodevelopment department for the Japanese operator, also noted that there are advantages to considering 5G development alongside 4G.

“Of course, we need to reduce the cost for 5G. Maybe at the beginning, we do the interworking with 4G, we have already nationwide coverage for 4G, and where we have some hotspot areas, or event areas, we can use 5G. We don’t need to deploy 5G nationwide at the beginning, we can introduce it when we want,” he said.

EE’s Hanif said that the operator’s motivation for its network evolution is to win a “global race”, but that it’s “not between us and Docomo, or us and SK Telecom”.

“There’s a global race between customer expectation and customer experience. Why is that so difficult? It’s not because we are bad at what we do, but because customer expectation is constantly rising, it keeps moving,” he said.

“What will solve that puzzle of getting ahead of customer expectation? Will it be 5G? Will it be 4G? I don’t really care, what I’m really keen on, here in the UK at least, is that we get there as soon as possible,” the executive continued.

Radio evolution
With 5G radio evolution being where much of the heavy lifting still needs to be done, Docomo’s Abeta noted that in terms of requirements for the new technology, much of the demand is an evolution of what has gone before.

“Some requirements already exist every time we upgrade, for example higher data rates, lower costs, higher spectrum efficiency. With 4G, we added lower latency. Those traditional requirements, of course, we need to improve, so we set higher requirements for 5G. But with 5G, we have new requirements,” he said.

These new needs, he continued, are related to the need to support new use cases resulting from the internet of things, which will see a massive number of devices connected to the network, with different needs in terms of latency, bandwidth and power.

But as yet, it is not clear what spectrum will be available for 5G networks. Docomo is already working on trials with multiple vendors, part of which is “trying to understand the characteristics of each band,” Abeta said.

Docomo is working with Nokia on millimetre wave pilots, using frequencies in the 70GHz band. Nokia’s Twist said: “One of the things we are looking at particularly with centimetre wave and millimetre wave, one of the reasons for going there, is because there are broad swathes of spectrum at that frequency which is not being used for other things.”

Small cells
For the UK market, EE’s Hanif said that in terms of radio technology, the first home is likely to be small cells – with the reason being somewhat prosaic.

“It’s hugely expensive to do macrocell upgrades. That will influence the way we approach 5G, because the last thing I want to do is go and swap out more antennas, speak to all the landlords, renegotiate the rights again – the kind of thing you normally do every 15 to 20 years,” he said.

“The timing is such in the UK that all the big operators are right now going through this massively difficult, painful and expensive upgrade programme. I can’t see us having the appetite to go and swap those antennas out again anytime soon,” the executive continued.

Mobile Edge Computing

EE’s Hanif EE-log-Nov-2014 was vocal in his support for Mobile Edge Computing, where computing capabilities are pushed closer to the radio access network (and, in turn, closer to subscribers), enabling low-latency and high-bandwidth access to content, applications and services.

“You’re putting the computing power and the value right where the customer needs it the most,” he said.

But as yet EE’s engagement with Mobile Edge Computing has been limited because “not all of our network is Nokia” – the vendor was an early proponent of the technology through its Liquid Applications portfolio.

“Is this going to work across our whole network? We don’t want to discriminate against our customers based on which base station they are under,” he said.

The technology has now picked-up wider industry support, with vendors such as IBM, Intel and Huawei joining Nokia, and NTT Docomo and Vodafone among the members of ETSI’s mobile edge computing working group.

DOCOMO to Offer Japan’s First eSIM for M2M Devices

NTT DOCOMO, INC., a personalized mobile solutions provider for smarter living, announced today it will offer Japan’s first Embedded Subscription Identity Module, or eSIM, a new type of SIM that works on mobile networks of various international operators, for M2M Devices.

DOCOMO’s eSIM, which is able to register phone numbers and other subscription-identity data of DOCOMO and other international operators in machine-to-machine (M2M) devices, such as connected automobiles, industrial equipment and many more, will be available to business customers from June 30.

Conventionally, connecting a M2M device to a local mobile network requires a SIM offered by the operator. DOCOMO’s new eSIM, however, will enable a single embedded SIM to load subscriber identities issued by multiple mobile operators. This will simplify manufacturing and inventory-management tasks over operator-specific SIMs, a major advantage for transnational M2M enterprises and solution providers. Also, subscriber identities stored in the eSIM will be interchangeable as the user moves from country to country with their M2M device, leading to enhanced operability.

DOCOMO’s eSIM will be available as a M2M solution for corporate customers using the docomo M2M Platform in Japan.

The eSIM is an emerging technology in the global M2M industry. DOCOMO, a member of GSMA, has been actively involved in the establishment of an eSIM global standard, which was officially released in December 2013. Going forward, DOCOMO is committed to offering advanced M2M services to support Japanese and international business customers.



NTT Docomo models smart clothing and aims for 2014 launch

Japan’s NTT Docomo is plotting a move into smart clothing at the back end of this year – and is using Mobile Asia Expo to demonstrate how potential new products will work, the operator has told Mobile Asia Daily.

The clothes are created from material that enables bioelectrical signals to be stored and then processed in the cloud.  Docomo is looking for applications in the sports and healthcare markets to commercially exploit its work.

For instance, the clothing could record heartbeats and electrocardiograms and forward them to a system which manages the data remotely. This application opens up significant markets in the health sector such as patients with chronic ailments or the elderly. At the other end of the health spectrum, quantified self-movement is another possibility, as well as runners and other athletes.

Docomo is planning to offer services based on some of the smart clothing features within the next year, probably as soon as December 2014.

This week’s event will also see the operator demonstrating its M2M platform which is already used by several sectors, including automotive and construction.  It is also looking to branch out into other sectors.

Much M2M activity is focused on the enterprise but Docomo is also offering consumer services such as car navigation systems or pet monitoring services.

Finally, Docomo’s Mobizen service will be on show which allows users to remotely link their PCs and smartphones to transfer data and control applications. The service is designed for sales management and information distribution.

A separate demonstration of the related Smartphone Anshin Remote Support will show a screen being shared with users so that a Docomo helpdesk operator can remotely provide operational support.
