5G E2E network slicing will play a key role for mobile operators by enabling multiple virtual networks to be created within a single physical network infrastructure. Each virtual network will have different service characteristics, referred to as ‘slices’ that allow mobile carriers to create new services and business models.

For instance, within the same mobile network, operators can create a low latency-focused slice dedicated to automated vehicle drivers, while a separate high bandwidth slice can be created for video streamers. Both slices can be provided simultaneously without deploying additional network resources or hindering the quality of service in either case.

For businesses, network slicing can be used to prioritize different performance needs, such as when hospitals must prioritize more bandwidth to emergency room admissions, and less to visitor services.

Through the demonstration, Samsung and KDDI explored the capabilities of 5G E2E network slicing, including verification of the following: low latency, guaranteed throughputs, and the creation of multiple slices. Furthermore, a RAN Intelligent Controller (RIC) that manages radio resources to guarantee required service levels, was demonstrated. Samsung and KDDI aim to standardize E2E network slicing in an international standard organization.

5G E2E network slicing will enable mobile carriers to save on deployment costs with its ability to create distinctive, virtual slices in the same network. Without network slicing, carriers must deploy additional RAN and core to implement new business models, such as smart city applications. Additionally, it will allow quick ramping of new business services by maintaining existing service levels, reducing time-to-market and improving operational efficiency.

“The demonstration provides a foundation that will allow KDDI to offer new 5G commercial services leveraging its 5G commercial networks,” said Toshikazu Yokai, Executive Officer, General Manager of Mobile Network Technical Development Division at KDDI. “Working with Samsung, we will continue to accelerate growth in advanced 5G technologies to benefit our customers.”

“KDDI has been continuously working toward developing a wide range of new 5G use cases that can elevate the everyday lives of our users,” said Yoshiaki Uchida, Member of the Board, Executive Vice President at KDDI. “Together with Samsung, KDDI will continue to explore ways to provide unprecedented experiences by integrating communications and life design.”

“It is exciting to see how 5G technology can transform our lives,” said Youngky Kim, President and Head of Networks Business at Samsung Electronics. “5G is now a reality. We will continue working with KDDI to explore how the technology can be further developed and applied in our homes and cities.”

Real-time transmission of high-volume videos to mobile devices or large screens is expected to take viewing experience to a whole new level in crowded entertainment and sports venues. By allowing simultaneous transmission of high-volume videos, 5G enables what the preceding mobile technologies were incapable of realizing.

By showing that audiences are now able to view sports games from any angle of their choice and at incredible resolution, today’s test verified that the viewing experience has been taken to a whole new level. It will add a much greater depth to the traditional viewing experience on television broadcast.

Free-viewpoint video is a technology developed by KDDI Research that enables users to view a video from any viewpoint via reconstructing 3D model for human objects and background objects such as the stadium field.

KDDI and Samsung Electronics today announced the successful completion of a 5G field trial held in Okinawa Cellular Stadium, a 30,000-person capacity baseball stadium in Japan.

Using Samsung’s 5G end-to-end solutions spanning virtualized core, virtualized RAN, one of the smallest 5G access units, and multiple prototype 5G tablet devices, the trial showcased a live feed of 4K video contents downloaded and streamed simultaneously on 5G tablets supporting the millimeter wave spectrum. This is the first time to test 5G performance using 5G tablets in Japan.

Samsung’s 5G access units with beam-forming technology were installed on a light tower located outside the left field fence to create 5G coverage in the direction of home plate and first and third bases. As a result, the tablets placed on seats in this coverage area were able to have 4K videos downloaded and streamed on them via 5G.

The successful trial results reflect the two companies’ efforts in using 5G technology and ultra-high frequency spectrum (28GHz band in this instance), to redefine user experiences in crowded environments and spotlight a new approach to viewing sports games.

“We have been working closely with Samsung to explore 5G. It is exciting to see how the technology will play out at crowded events to result in the discovery of new business models,” said Yoshiaki Uchida, Senior Managing Executive Officer at KDDI. “The trial is solid evidence of our potential to generate new use cases that will take user experience in sports stadiums to new heights in the 5G era.”

“5G holds the powerful potential to create new user experiences and business models that are more immersive and dynamic than ever before,” said Youngky Kim, President and Head of Networks Business at Samsung Electronics. “Through our collaboration with KDDI, we will stay committed to exploring 5G-driven business models that can be applied in diverse high-demand locations based on a wide range of methods.”

The outcome of this 5G stadium trial connotes advanced connectivity, not only at sports events, but also in a wide variety of crowded entertainment spots, including live music concerts, exhibitions, and international conferences, leading to new viewing experiences. By demonstrating how users will be able to simultaneously access 5G networks and enjoy immersive experiences regardless of their location, today’s accomplishment continues 5G momentum as it enters commercialization stage.

Since 2015, KDDI and Samsung have been working closely to demonstrate the performance of 5G in various real-life scenarios. This includes a multi-cell handover demonstration that took place in February 2017 where the device was mounted on a car that traveled the busy streets of Tokyo (Link), high-speed mobility test with the device attached on a car racing over 200km/hour (124 miles/hour) in Yongin, ‘Everland SPEEDWAY’ in Korea in September 2017 (Link) and the recent successful uplink/downlink handover test that took place on a high-speed train railway in Japan (Link). Samsung’s state-of-the-art technologies including the first commercial ASIC-based 5G modems and mmWave RFICs for compact access units, CPEs and tablets using in-house technology and assets laid down the framework for these demonstrations.

Samsung’s 5G devices, when installed in homes or enterprises, will automatically be recognized by 5G base stations and provided with ultra-fast broadband service of up to 1Gbps, while the network core equipment is responsible for resource management and real-time data traffic distribution.

Central to the initial phase of 5G is the notion of an ecosystem – an ecosystem that covers manufacturers of chipsets, devices and other equipment. Samsung stands out as a key player in the industry with end-to-end solutions that deal with each aspect of this 5G network cycle, enabling early 5G commercialization and stable service quality. This is precisely why Verizon, the largest mobile network operator in the U.S. and an industry leader when it comes to 5G commercialization, has selected Samsung as its vendor.

“What it means for a single company to be able to provide chips, devices and equipment is that it can optimize 5G and bring out the best of this new exciting technology all by itself,” said Tim Baxter, President of Samsung Electronics America. “Beginning this year, we plan on peeling off the layers, one by one, to show how a connected world built by a full 5G commercial product lineup will unfold before our eyes.”

Six Years of R&D Finally Coming to Fruition

Samsung has demonstrated its technological expertise throughout the evolution of communications – from 2G to 3G and 4G. Indeed, the company was the first to commercialize CDMA (Code-Division Multiple Access) during the 2G era. Samsung was also at the forefront of 4G LTE (Long-Term Evolution) innovation as a key vendor in technologically advanced markets such as the US, Japan, Korea and the UK. Its business has now expanded into rapidly developing India, where Samsung is the sole vendor of the country’s 4G LTE nationwide network.

Samsung has been convinced of the potential that the millimeter wave spectrum holds since 2012, and has been investing in 5G R&D ever since. These efforts have resulted in the successful development of beamforming technology that supports directional signal transmission or reception. Based on this achievement, a technology that enables transmission speeds of over 1Gbps and is capable of covering distances of up to 2 kilometers using a 28 GHz band was developed and demonstrated in May of 2013.

In October of 2014, for the first time in the industry’s history, Samsung Electronics took 5G technology out of the lab and demonstrated its use in a vehicle moving at 100 km/h

In 2014, a seamless data transmission speed of 1.2Gpbs was achieved during a demonstration held in a vehicle moving at 100 km/h. It was the time that 5G technology had reached Gbps-level speed in a mobile environment. When the vehicle was stationary, the speeds reached 7.5Gbps, which was another new record.

That was directly followed by the first successful demonstration of 5G handover technology, which has allowed Samsung to further accelerate 5G’s commercialization. Handover is regarded as a critical technology for networks as it signifies seamless coverage for smart devices when a user moves between base stations. In March of 2016, Samsung became the first in the industry to successfully accomplish a multi-cell handover demonstration by achieving Gbps-level connectivity while a vehicle moved across three 5G base stations at 25 km/h.

In September of 2017, Samsung demonstrated seamless connectivity with a vehicle traveling at over 200 km/h, as well as a successful handover with a vehicle moving at 192 km/h. These remarkable achievements proved that the application of 5G on high-speed trains was a feasible concept.

Around this time, Samsung also successfully proved the capabilities of a 4G-5G intertwined network that binds together three spectrums by linking a 4G LTE network that utilizes the 2.6 GHz band with a 5G network that uses the 28 GHz and 3.5 GHz bands. Interworking between different-generation networks is recognized in the industry as a prerequisite for fostering 5G commercialization.

Accelerating the 5G Era with Operators Worldwide

By nature, telecommunications service can only begin once an operator has acquired the rights to use a particular spectrum from its government and established infrastructure with its vendor. It is absolutely crucial that the service allows multiple users to simultaneously enjoy seamless connection anywhere and anytime. 5G commercialization is no exception to this rule; cooperation between operators, equipment vendors and device manufacturers is a must.

Samsung has been focusing on intensifying its technical and business bonds with operators in markets with advanced 5G adoption such as Korea, the US and Japan. The US is the first country to have acquired the 28 GHz spectrum, and it plans on launching FWA (fixed wireless access) service using 5G technology in the second half of this year. Samsung is in the midst of carrying out 5G trial services in key US cities together with Verizon and has already deployed 5G networks in seven of the eleven cities – Sacramento included – where Verizon provides its service. To add to the list are the 5G trials being carried out in Indiana with AT&T, as well as another with T-Mobile.

Korea is quickly gaining recognition as a testbed for the latest technologies. In September of 2017, together with the Korean telecommunications operator SK Telecom, Samsung successfully demonstrated, for the first time ever, how 4G and 5G networks can interwork with one another.

Japan has targeted the year 2020 for 5G commercialization, to coincide with a large-scale sporting event that will be held in Tokyo. Together with the country’s leading operator, NTT DOCOMO, Samsung successfully demonstrated the 5G technology in a vehicle traveling at high speed in November of 2016. With KDDI, another key operator in Japan, Samsung conducted a 5G demonstration on a Tokyo highway in February of last year. In December of the same year, the joint efforts extended into a 5G test held on a high-speed train.

Also collaborating with Samsung to accelerate 5G commercialization is the French operator Orange. Together with Korea Telecom and Verizon, Samsung has also established the specifications required for 5G trial services in Korea, as well as commercial FWA service in the U.S.

“Samsung has always been an active promoter of international cooperation with its 5G total solutions at the root,” said Wonil Roh, Vice President and Head of the Technology Strategy Group, Networks Business, Samsung Electronics. “These experiences are a validation of why operators worldwide find Samsung to be the most ideal partner for 5G network establishment.”

KDDI and Samsung Electronics have successfully completed the first 5G demonstration on a moving train traveling at over 100 km/hour (over 60 mph). This was achieved along a section of track where the distance between two stations was approximately 1.5km (nearly 1 mile). During the demonstration, the companies achieved a successful downlink and uplink handover as well as a peak speed of 1.7 Gbps.

The tests were carried out from October 17^th through the 19^th in the city of Saitama in Japan, near Tokyo. For the tests, Samsung’s 5G pre-commercial end-to-end solution was used, which is composed of a 5G router (CPE), radio access unit (5G Radio), virtualized RAN and virtualized core.

The demonstration leveraged capabilities driven by 5G, such as high throughput, low latency and massive connections, which verified potential services and use cases that would be highly-beneficial to passengers and operators of high-speed trains. This could pave the way to vastly improved backhaul for onboard WiFi, superior passenger infotainment and increased security and analytics.

In addition to a successful downlink and uplink handover at more than 100km/hour (over 60 mph), 8K video was downloaded via the CPE installed on-board, and a 4K video, filmed on a camera mounted on the train, was able to be uploaded.

“In collaboration with Samsung, KDDI has opened up the possibility for new 5G vertical business models, such as a high-speed train. With 5G expected to bring railway services to a whole new dimension, the success of today’s demonstration in everyday locations such as a train and a train station is an important milestone indicating 5G commercialization is near,” said Yoshiaki Uchida, Senior Managing Executive Officer at KDDI. “To fulfill our aim to launch 5G by 2020, KDDI will continue exploring real-life scenario experiments for diverse 5G use and business cases together with Samsung.”

“The potentials that 5G holds is powerful enough to transform the landscape of our daily lives,” said Youngky Kim, President and Head of Networks Business at Samsung Electronics. “The success of today’s demonstration is a result of our joint research with KDDI, which we will continue to pursue as we explore next generation networks and use cases This will include research on diverse spectrums and technologies, as well as new business models and applications.”

Since 2015, KDDI and Samsung Electronics have been closely collaborating to demonstrate 5G millimeter wave performance in various scenarios. This includes a multi-cell handover demonstration that took place in February, where the device was mounted on a car that traveled in the busy streets of Tokyo (Link), and a high-speed mobility test with the device attached on a car racing at 200km/h in Yongin, Korea in September (Link).

We provide a multitude of services, including mobile phone services, fixed-line communication, and data centers, thus making us the optimum one-stop solution provider for everything telecommunications and IT environment related.

The demonstration, which took place at ‘Everland SPEEDWAY’ in Korea, involved a battery of individual tests to examine the performance of Samsung’s end-to-end 5G mmWave technology. Specifically, as a vehicle accelerated from 0 to 205km per hour on the race track between multiple 5G base stations, the test measured and evaluated a variety of metrics, including handover interruption time, uplink and downlink throughput stability, and latency stability (or “jitter”).

In addition, KDDI and Samsung also demonstrated a successful handover scenario, with Samsung’s 5G device attaching to the 5G base station as it approached the service area, and successfully being handed over to the target cell at a speed of 192km per hour (GPS speed).

Woojune Kim, Senior Vice President and Head of Next Generation Strategy in Networks Business at Samsung Electronics, said, “It is becoming increasingly important that we accelerate our focus on 5G’s ability to meet a growing number of performance metrics. Until now, peak bandwidth has been the common refrain, and certainly a big component of the future of 5G. However, the test we conducted with KDDI will help us build a more diverse portfolio of future 5G use cases.”

“The trial successfully showcased stable performance under high-speed mobility conditions which will dramatically increase the service experience of users in vehicles,” said Akira Matsunaga, Senior Director, Mobile Network Technical Development at KDDI. “We will continue our joint efforts with Samsung to test next generation technology to unprecedented levels and discover new service cases.”

The test achievements build upon a string of mobility-related successes over the past several years. In February of this year, Samsung and KDDI successfully demonstrated 5G handover capability in an urban city environment at speeds of up to 60km/h on public roads. Both companies are in discussion with 5G trials for multiple 5G service cases.

One of the most exciting prospects of 5G technology is the potential for new and highly specialized service scenarios that go beyond traditional smart device connectivity. 5G’s ability to deliver on this promise is directly tied to its ability to meet the unique performance needs of a wide number of increasingly-connected industries, from Smart City IoT to Connected Cars and more. Samsung also continues to actively explore the potential for 5G-driven services under common high-speed scenarios.

The 5G handover was successfully carried out in a test divided into two scenarios. First, a 5G device mounted on a vehicle that travelled at a speed limit of 60km/h drove between two 5G base stations on a metropolitan expressway.

The second scenario was designed to verify the characteristics and performance of the 28GHz spectrum in Line of Sight (LOS) and Non Line of Sight (NLOS) environments. At the LOS environment, the vehicle drove through the heart of the city and as a result, a maximum throughput of 3.7Gbps was achieved. This is especially the case with highly dense metropolitan areas such as Tokyo, packed with skyscrapers as well as a myriad of obstacles of various materials from glass and concrete to wood and metals.

“We are pleased to have proven the feasibility of 5G mobility service in Tokyo, one of the densest cities in the world,” said WooJune Kim, Vice President and Head of Next Generation Strategy at Samsung Electronics. “Through today’s demonstration, we have proven that challenges that are likely to occur at highly dense metropolitan areas can be successfully overcome when the right technologies are implemented. Together with KDDI, we look forward to taking steps toward the realization of 5G-driven services.”

Handover between 5G base stations is a required element to maintain a seamless data connection during a user’s movement between base station coverage, making it a critical enabler of 5G commercialization. As 5G communication technology utilizes beam forming technology that tightly focuses radio waves into narrow beams, both the device and base station need to rapidly search for the optimal beam combination, calculate the ideal radio signal, and seamlessly relay data traffic between base stations.

Ever since the deployment of KDDI’s commercial CDMA network in 2002, Samsung has been closely cooperating with the operator through to the latest LTE-A technologies. The two companies have extended and strengthened their partnership in order to tackle the challenges and potentials of 5G, an area that Samsung has been focusing its research on since 2011.
