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."

Nokia and KDDI trial 5G on 28 GHz

Nokia and Japanese operator KDDI, serving around 40 million mobile subscribers, announced they have conducted a trial simulating future 5G network demands, providing high-speed, gigabit connectivity inside an apartment block utilising Nokia radio technology on the 28 GHz band.

The trial, conducted between the KDDI Research building and a residential apartment approximately 100 meters away, achieved speeds in excess of 1 Gbit/s over the 28 GHz band, demonstrating how 5G technology can be used inside apartment blocks to meet demand for wireless ultra-broadband including in major cities such as Tokyo, which is estimated to be the world's most densely populated metro area.

The trial with KDDI was carried out in Fujimino City, Saitama Prefecture and represents the first in a series of planned 5G collaborations between Nokia and KDDI following the signing of a Memorandum of Understanding (MoU) in 2016 to develop technologies for a new, faster generation of wireless communications.

The trial specifically involved the Nokia AirScale base station, part of its 5G FIRST end-to-end solution, which provided coverage and connectivity to the apartment block. In addition, Nokia AirFrame provided a commercial platform to enable the cloud RAN and support the transmission of streaming data.




  • Last December, Nokia announced that KDDI had deployed its Motive Service Management Platform (SMP) to enhance customer care by streamlining and speeding the resolution of issues for its mobile subscribers. Nokia Motive SMP enables KDDI to improve the detection, troubleshooting and resolution of issues when subscribers use online self-care tools. KDDI was to deploy Motive SMP across its service areas in Japan via Amazon Web Services (AWS).

NEC teams with Red Hat for trial of KDDI next generation enterprise platform

NEC announced that it contributed to a successful trial of a next generation enterprise platform by KDDI of Japan, a telecommunications and ICT solution provider serving around 40 million domestic mobile subscribers and over 2,000 large enterprises, in collaboration with Red Hat K.K.

NEC noted that as adoption of 5G and IoT services increases, it anticipates that rapid and efficient development and operation of services will be required across a larger number of servers and network infrastructure systems. As part of its effort to deliver this, NEC participated in trials with Red Hat designed to verify the feasibility of KDDI's next generation integrated platform, which incorporates infrastructure and IaaS elements, and its ability to operate with multiple types of systems.

The recent trials with KDDI, which were conducted earlier in 2017, confirmed the feasibility of delivering advanced functionality including:

1.         The use of open cloud technology to deliver quality, reliable system infrastructure for telecommunications carriers.

2.         Integrated management of multiple services using simplified infrastructure, flexible services and efficient operations.

3.         The maintenance and replacement of servers and storage devices without service interruptions.

4.         The provision of advanced monitoring utilising distributed technology developed by the KDDI Research Institute.

NEC stated that the trials were based on the Red Hat OpenStack Platform, which was used to create an open cloud environment, with the infrastructure implemented and managed by NEC. NEC plans to continue working with Red Hat to help deliver the performance needed for KDDI's next generation platform.

KDDI Picks Ciena for JIH Cable Upgrade

KDDI has selected Ciena for the Japan Information Highway (JIH) submarine cable upgrade project.

Ciena’s GeoMesh submarine solutions will be used to provide high-capacity 100G services on KDDI's 3,000km link from Miyazaki-to-Okinawa and Shima-to-Okinawa.

Since 1999 KDDI’s JIH submarine cable has been providing connectivity to the Japanese main islands. The upgrade will add significant capacity on this vital network route.

KDDI to Invest US$270M in New Data Centers in Tokyo, Osaka

KDDI will invest US$270 million (28 billion yen) in building two new TELEHOUSE data centers in Tokyo and Osaka. The company cites a growing demand for data center space in Japan.

TELEHOUSE OSAKA 2 and TELEHOUSE TOKYO Tama 3 are scheduled to open in August 2015 and February 2016 respectively. TELEHOUSE Osaka 2, in the center of Osaka city, will offer 700 racks of tenancy space with up to 30kVA (designed) per rack. Both facilities will offer high-density colocation services enabling the hosting of heavy load IT infrastructure. TELEHOUSE Tokyo Tama 3 will be located on the existing Tama data center campus, 30km from the Tokyo city center in a highly guarded surrounding. The five storey building will offer 1,300 racks of tenancy space with up to 42kVA (designed) power supply to racks, the highest in Japan and 5 times industry average, with a designed PUE 1.31 making it one of the most energy efficient data centers in Japan.

These additional facilities will take the total amount of global TELEHOUSE data center space to 371,000 sqm provided by 46 sites across 13 countries/territories and 24 major cities.
