KDDI and Samsung prove 5G mmWave works at 190 kmh

KDDI and Samsung Electronics completed a series of 5G tests which demonstrate the viability and performance of 5G millimeter wave mobility solutions while traveling at speeds over 190km per hour.

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 Network 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."

SK Telecom Develops 5G Repeater

SK Telecom ha developed a 5G repeater that improves signals in blanket/shadow areas by amplifying 5G radio signals. The 5G repeater, which is currently in a field trial Gangnam Station in Seoul, could held reduce or elimiate shadow areas of network coverage.  It works by improving the propagation characteristics of radio signals at super-high/above-6GHz frequency bands.

SK Telecom said the Gangnam area in Seoul is one of the most difficult places to plan/build a network due to the presence of a large number of radio wave obstacles and high-density data traffic.

“SK Telecom is moving closer to launching a commercial 5G network by applying key 5G technologies to our 5G trial network in Gangnam, an area with the highest data traffic,” said Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center of SK Telecom.

SK Telecom – setting the pace in the 5G race


SK Telecom, South Korea's leading mobile operator by market share, is one of the big players to watch on the global stage for early 5G commercialisation. In fact, a race is on with local rivals KT and LG Uplus to have the first 5G service running in time for the 2018 Winter Olympics, which will be hosted in Pyeongchang, South Korea in February 2018 - only seven months away. Of course, 5G standards are not complete and won't be in time for the Winter...

SK Telecom commercialises T-MANO NFV

Korea's SK Telecom announced that it has commercialised T-MANO, an NFV MANO (network functions virtualisation management and orchestration) platform that performs integrated management and orchestration of virtualised network equipment and software.

SK Telecom noted that NFV MANO, also termed MANO, provides an architectural framework for managing and orchestrating virtualised network functions (VNFs) and other software components. The new T-MANO solution has been optimised to SK Telecom's network environment, and is based on the ETSI specifications that define the MANO architecture to facilitate the deployment and connection of services as they are decoupled from dedicated physical devices and moved on to virtual machines (VMs).

Prior to the development of T-MANO, SK Telecom stated that it was necessary to develop, build and operate a separate NFV management platform for each network equipment provider due to the fact that each piece of NFV equipment was based on different specifications, depending on the manufacturer.

Leveraging T-MANO, SK Telecom is able to more efficiently utilise its virtualised network equipment by managing service quality and data traffic in an integrated manner, regardless of equipment manufacturer, while improving the overall service quality through responding flexibly to service failures and errors.

The solution also enables the company to significantly reduce the time required to set up new equipment and provide a new service as it can upgrade the whole system at once, as opposed to upgrading each system separately as was necessary previously.

SK Telecom intends to leverage T-MANO to expand the telecommunications infrastructure ecosystem by opening up the APIs of T-MANO so that the industry can use it to build virtualised network equipment or software.

The company will first apply T-MANO to its virtualised VoLTE (HD Voice) routers, and then plans to expand its application to the virtualised LTE evolved packet core (EPC) and additional equipment including MMS Servers. SK Telecom stated that in 2017, virtualised EPC will account for around 80% of newly-deployed EPC equipment, while from 2019 it intends to deploy only virtualised EPC solutions.

In the field of NFV, SK Telecom has also commercialised an international standards-based NFV system orchestrator, named T OVEN, that was unveiled in 2015, and applied NFV technology to its base station equipment in September 2016.

SK Telecom – setting the pace in the 5G race

SK Telecom, South Korea's leading mobile operator by market share, is one of the big players to watch on the global stage for early 5G commercialisation. In fact, a race is on with local rivals KT and LG Uplus to have the first 5G service running in time for the 2018 Winter Olympics, which will be hosted in Pyeongchang, South Korea in February 2018 - only seven months away. Of course, 5G standards are not complete and won't be in time for the Winter Olympics, which means that network planners will be rushing to show off systems that have barely been tested. Sceptics will say that 5G demos at Pyeongchang are likely to be very limited in their footprint and perhaps only 4.5G rather than truly next gen. However, SK Telecom has a track record of being first with many networking technologies, extending back to its earliest days in CDMA.

Background

South Korea's mobile market is one of the most mature in the world. There are three dominant mobile operators: SK Telecom (approximately 49% share), KT and LG Uplus. Mobile penetration has exceeded 110% for years. The majority of users are on subscription-based plans, rather than prepaid, and churn is relatively light compared to other countries.

SK Telecom, part of the SK Group conglomerate (chaebol), was founded in 1984 and has a CDMA network architecture heritage. For its most recently reported fiscal quarter, SK Telecom posted revenue of KRW 4.234 trillion, operating income of KRW 410.5 billion, basically flat from a year earlier, and net income of KRW 583.5 billion, up 2.1 %YoY. As of the end of March 2017, SK Telecom had 21.65 million LTE subscribers, representing a 10.9% YoY growth, and taking up 72.6% of the company's total mobile subscriber base of 29.83 million. ARPU was KRW 34,927 ($31.04), down 2.9% YoY. SK Telecom also operates the Cyworld social network and virtual reality service as well as the Nate-on messaging application.

First in Carrier Aggregation

This week, SK Telecom announced the launch of LTE-A Pro service, which it described as the last stage of LTE evolution. The service footprint covers the main areas of six major cities: Seoul, Busan, Daegu, Gwangju, Daejeon and Ulsan. The initial LTE-A Pro service uses three-band/four-band carrier aggregation (CA) to deliver rates of up to 700 Mbit/s. When 4 x 4 MIMO is added, the service accelerates to 900 Mbit/s. SK Telecom plans to scale up LTE-A Pro further using five-band CA with 4 x 4 MIMO to achieve 1.2 Gbit/s peak rates. The first mobile device to support the LTE-A Pro service is Samsung’s Galaxy S8. An over-the-air firmware update will be needed to support the additional CA bands.

SK Telecom's spectrum resources include 10 MHz bandwidth in the 800 MHz band, 20 MHz bandwidth in the 1.8 GHz band, 10 MHz bandwidth in the 2.1 GHz band, 10 MHz + 20 MHz bandwidths in the 2.6 Ghz band.

Peak speeds of 700 Mbit/s and up on a mobile phone are certainly impressive. Actually, SK Telecom has been delivering a 500 Mbit/s mobile service since June 2016 using 256QAM combined with tri-band CA. Four years ago, in June 2013, SK Telecom launched the  first LTE-A service, which boasted download speeds of up to 150 Mbit/s, which is two times faster than its regular LTE service and 10 times faster than its 3G network. This was achieved using CA across two 10 MHz channels, along with the first Coordinated Multi Point (CoMP) implementation. Samsung's Galaxy S4 handset, which was the latest and greatest model in the summer of 2013, was the starring device for this milestone service launch as well.

Many world capitals today have yet to attain the 150 Mbit/s performance peaks offered in Seoul four years ago. But surprisingly, SK Telecom's LTE adoption rate amongst is 29.8 million mobile subscribers was only 72%, or 21.6 million users, as of March 2017. This means that even for a mobile operator with the most advanced network in the world, a significant percentage of users are laggards when it comes to updating to the latest service.

Recently, SK Telecom gained recognition for two other technology innovations: 5G mmWave Handover and a Green Scheduler with Lean Carrier algorithm. Both advances won Global Telecoms Business (GTB) Innovation Awards last month. The 5G mmWave handover technology, developed with Samsung, supports Gbit/s-level performance using multiple mmWave 5G base stations. The companies used the Ray Tracing method to calculate the optimal location of mmWave base stations. SK Telecom and Samsung also cited their work in 3D beamforming to resolve attenuation of radio signals in mmWave frequencies. The Green Scheduler with Lean Carrier technology, which was developed in partnership with Ericsson, enhances network energy efficiency while reducing signal interference.

With Ericsson, SK Telecom is also known to be working on a 5G connected car program. Earlier this year, SK Telecom, Ericsson and BMW Korea achieved a peak rate of 3.6 Gbit/s for a connected vehicle travelling at a speed of 170 km per hour. To pull this off, the three companies deployed the world largest mmWave 5G trial network using the 28 GHz band. Beamforming and beam tracking technologies were used to optimise the connection to the speeding car.

Leaping ahead in quantum technologies

To further illustrate its interest in pushing technological boundaries, SK Telecom signed separate research partnerships earlier this year with Nokia and Deutsche Telecom focused on quantum cryptography. The first partnership will match SK Telecom's Quantum Key Distribution System (QKD) with Nokia’s next-generation optical transport system. The first prototype was shown at Mobile World Congress in February.

Nokia and SK Telecom are also collaborating on a Quantum Random Number Generator (QRNG), which is seen a key technology for applying quantum cryptography technologies to IoT devices. SK Telecom has developed what it claims to be the world’s smallest 5 x 5 mm CMOS Image Sensor (CIS) based all-in-one, single silicon (ASIC) for providing non-deterministic true random numbers on demand from quantum-shot noise. The plan is to commercialise the technology to enable secure IoT.

SK Telecom's Quantum Alliance with Deutsche Telekom is more open. At this stage, the agreement aims to the channels of communications open between carriers and vendors when it comes to quantum technologies. The official statement from the company, by, Cha In-hyok, EVP and head of IoT business division, states:

    “Committed to building a quantum-safe future, SK Telecom has been actively developing quantum cryptography technologies since 2011. SK Telecom believes that the co-establishment of the Quantum Alliance with Deutsche Telekom will bring us closer to realizing this goal, while also creating new valuable business opportunities in areas including quantum-safe communications, the Internet of Things and big data. It will work together to accelerate the growth of quantum-based cybersecurity technologies and its ecosystem".

Sprint and Samsung test massive MIMO on 2.5 GHz

U.S. operator Sprint, a Softbank company, and Samsung Electronics announced that on the streets of the city of Suwon in South Korea they recently tested massive MIMO on 2.5 GHz spectrum in a real-world environment to support Sprint's efforts to increase LTE Plus wireless capacity and coverage and offer gigabit service to its customers.

During the field testing in Suwon, massive MIMO Samsung radios, equipped with vertical and horizontal beamforming technology, achieved peak speeds of 330 Mbit/s per channel using a 20 MHz channel of 2.5 GHz spectrum. The companies stated that capacity per channel increased approximately four-fold, cell edge performance increased three times and the overall coverage area expanded compared with current radios.

Sprint has deployed 8T8R (8 transmit, 8 receive) radios across its U.S. network, and the test with Samsung was designed to compare the performance of massive MIMO radios with 8T8R radios. The test cases and requirements were jointly developed by Sprint and Samsung and included a variety of performance scenarios involving multi-user and non-stationary testing.

For the tests, Samsung provided the massive MIMO network infrastructure as well as test network design, operation, data collection and processing. Both companies plan to use the results of the testing to prepare for the commercial deployment of massive MIMO in the U.S. and in other markets globally.

Samsung noted that massive MIMO radios involve the use of more antenna elements, for example, 64T64R uses 128 antenna elements, whereas 2T2R/4T4R/8T8R configurations are used in a typical 4G LTE network. The massive MIMO antennas also use advanced horizontal and vertical beamforming technology to focus and transmit cellular signals into targeted locations. This enables more efficient use of spectrum to deliver faster speeds and higher data capacity in high-traffic locations.

Sprint plans to deploy massive MIMO radios with 128 antenna elements (64T64R) using its 2.5 GHz spectrum in cities across the U.S. to increase capacity by up to eight-fold. In March, Sprint became the first U.S. carrier to introduce gigabit-class LTE on a live commercial network with a launch in New Orleans.


In New Orleans, Sprint implemented three-channel carrier aggregation and 60 MHz of 2.5 GHz spectrum, combined with 4 x 4 MIMO and 256QAM higher order modulation to achieve Category 16 LTE download data speeds over a TDD network. With massive MIMO radios using 64T64R, Sprint expects to be able to deliver capacity beyond 1 Gbit/s and reach between 3 and 6 Gbit/s bandwidth per sector.

Dong-Eui University, a leading private university in South Korea, is using Brocade's VCS Fabric technology to virtualize its data center.

The scalable network infrastructure is capable of supporting the high-bandwidth requirements of multiple Virtual Machines (VMs) running on VMware ESXi hosts.

The BROCADE VDX 6740 SWITCHES support up to 64 wire-speed 10 Gigabit Ethernet (GbE) ports, with the units being deployed with an initial 24 active ports and the option to activate more in eight-port increments under Brocade's pay-as-you grow Ports on Demand (PoD) licensing model. Thanks to the embedded VCS Fabric technology, any additional switches connected to the network are auto-configured to become part of the Ethernet fabric, which acts as a single intelligent switch.

In addition to the Brocade VDX 6740 switches, the university has also deployed BROCADE 6510 SAN SWITCHES to support its virtualization program. While these switches provide Gen 5 Fibre Channel (16 Gigabits per second) ports rather than 10 GbE, they mirror the Brocade VDX switches in many respects, offering pay-as-you-grow scalability along with self-learning, self-healing fabric configuration.

Nokia Hits 428 Mbps w TD-LTE with 3-Band CA and 256QAM

Nokia Networks, together with SK Telecom, demonstrated 428 Mbps data transmission using TD-LTE 3xCA with 256 QAM.

The test used a Qualcomm  Snapdragon X12 LTE modem along with Nokia's Flexi Multiradio 10 Base Station and software to aggregate three carriers on the TD-LTE band 41 spectrum (2496 – 2690 MHz).

The companies said this lays the foundation for the introduction of TD-LTE in Korea, with Nokia’s Single RAN Advanced platform as a foundation for SK Telecom.

  • In November, Nokia Networks has achieved a transmission speed of 19.1 Gbps and lower latency using 5G cmWave technology in a trial in South Korea. 
  • The trial used an OFDMA-based TDD system with 4x100 MHz carriers and 8x8 Multiple-Input Multiple-Output (MIMO), enabling eight independent data streams sent between the base station and the user device. In addition, 256QAM modulation enables the sending of eight bits of information per modulation symbol. The scaled OFDM has a shorter symbol length and Transmit Time Interval (TTI) that is expected to achieve a lower latency than with LTE.
