KDDI, a leading telecommunications operator in Japan, is deploying Nokia's G.fast solution to apartments and multi-dwelling units (MDU) buildings to deliver ultra-broadband services to customers.

Reducing the need to install new fiber, Nokia's technology will enable KDDI to use existing copper lines in MDU buildings to deliver 830Mbps combined uplink and downlink speeds to customers.

To support customers' ultra-broadband needs, Japanese operators are using fiber where possible along with new technologies like G.fast for a large number of MDU locations where copper is already installed.

Developed by Nokia Bell Labs, G.fast uses vectoring technology to effectively reduce cross-talk interference that typically impacts data speeds over copper networks. 

Providing support for Japan's VDSL2 specifications, Nokia's G.fast solution will minimize the impact to existing VDSL systems and enable operators to quickly upgrade their high-speed internet service to gigabit class through a simple CPE (customer premises equipment) replacement.  

KDDI has been deploying Nokia's G.fast solution and has started its rollout of 'au Hikari MDU Type G'.

Teresa Mastrangelo, principal analyst at Broadband Trends said: "G.fast continues to be a preferred choice for operators seeking to deliver gigabit broadband services to MDUs as it eliminates many of the issues found with FTTH deployments such as building types and access.  However, in Japan, deploying G.fast can be just as challenging as fiber due to the unique VDSL ecosystem and standards in place. 

As one of the few vendors capable of supporting both the global and local Japanese VDSL standard, Nokia has been able to help KDDI capitalize on the benefits of G.fast and seamlessly scale and migrate their network with minimal disruption.  This win is another great example for how G.fast technology is being used to quickly address customers need for greater broadband speeds."    

Shigenari Saito, Administrative Officer, General Manager, Network Technology Development Division, Technology Sector, at KDDI said:

"KDDI already provides 10Gbps service for our 'au Hikari' FTTH customers, but the speed we can provide has been limited to 100Mbps service for MDUs where fiber is difficult to deploy.  Nokia's G.fast solution enables us to connect existing 100Mbps users and new G.fast users under the same DPU (distribution point unit).  This gives us the flexibility and economical path to meet the customer's demands for higher speed.  Our decision to deploy Nokia G.fast is based on our long-term relationship and Nokia continues to be our long-term partner for delivering technology innovations."

Sandra Motley, president of Nokia's Fixed Networks Business Group, said: "Operators looking to quickly roll out new ultra-broadband services are increasingly adopting multi-technology strategies that allow them to maximize the use of both fiber and copper technologies. This is particularly true in some cases like inside an apartment building, where more traditional Fiber-to-the-Home solutions can be very challenging to deploy. We are excited to be working with KDDI to deploy our G.fast solution to deliver fiber-like speeds that will enhance the way customers experience their broadband services."

KDDI and Samsung break record in high-speed 5G mobility test

Written on Sunday, 17 September 2017 08:59

Japanese telecom operator KDDI and Samsung Electronics announced the completion of a comprehensive set of 5G tests which demonstrate the viability and performance of 5G millimeter wave mobility solutions at speeds over 190km per hour which is the fastest record in the world. The successful results highlight the potential and capability of 5G to support a wide variety of future service scenarios.

The demonstration, which took place at 'Everland SPEEDWAY' in South 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").

"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."

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).

"It is becoming increasingly important that we accelerate our focus on 5G's ability to meet a growing number of performance metrics,” said Woojune Kim, Senior Vice President and Head of Next Generation Strategy in Network Business at Samsung Electronics. “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 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.

Japanese telco KDDI has deployed a new solution, Kentik Detect, for real-time network operations and planning efficiencies. With Kentik, KDDI gains the ability to make faster operational decisions and frees up engineering teams to spend more time on business innovation.

Telecommunications operators invest billions of dollars on their networks each year to maintain and enhance their service offerings and remain competitive. As part of that investment, network planning is a business-critical function that can significantly increase a telecom operator’s ability to meet customer expectations, capitalize on new market opportunities, and ultimately drive profits.

Rich network data is a key part of effective planning and can inform operators in determining when to launch new services and how to find more cost-efficient ways to deliver higher performance to customers. Yet, most telecom operators struggle to take advantage of their massive streams of network telemetry data.

“At KDDI, we strive to be continuously innovative across our entire organization. However, for our network engineers, that ability was previously held back by the amount of time the team was spending on tracking down answers about our network,” said Toru Maruta, general manager of the IP Network Dept. at KDDI. 

“Given the sheer scale and complexity of our network and the amount of data it generates, network planning analyses often took days to compile. Using Kentik Detect, our team can now access a rich dataset that offers valuable insights about our network within seconds. Kentik gives us the answers we need to build a better network.”

One of the most distinguishing aspects of Kentik Detect that caught KDDI’s attention is the solution’s powerful, intuitive visualization of complex data. Using the Kentik solution, KDDI’s network engineers can easily pivot between visualizations to get multi-dimensional analyses of their network in real time.

 “For the world’s leading telecommunications operators likes KDDI, being able to derive value from their own rich network data is a competitive advantage,” said Avi Freedman, co-founder and CEO of Kentik.

“Organizations that use the fastest, most comprehensive data analytics will drive revenue and performance, and can turn their data into powerful insights that drive better business decisions for them and for their customers. KDDI is one of our fastest-moving customers, and we look forward to our continued partnership as they roll out additional services enabled by network traffic intelligence from their Kentik platform.”

Unlike traditional appliance-based network monitoring tools, Kentik’s software-as-a-service (SaaS) big data network traffic intelligence platform is highly scalable, flexible and fast. With Kentik, telecommunications providers, ISPs, enterprises, and web companies can improve operations, optimize capacity, resolve anomalies, automate DDoS defense, and protect applications and service performance.
