The market value of SoftBank Group, Uber’s biggest stakeholder, has decreased by $16 billion following Uber’s disappointing initial public offering.
Nokia announced today it is working with Rakuten to build a new mobile network in Japan. Nokia will provide full turnkey services to plan, manage, deploy and integrate cloud RAN, AirGile cloud-native core network technology and several Nokia software functions.
Headquartered in Tokyo, Japan, the Rakuten Group offers more than 70 services in e-commerce, fintech, digital content and communications to more than 1.2 billion members across the globe. Rakuten will leverage its experience as an IT company and its membership base of more than 100 million users in Japan as it enters the market as a Greenfield mobile operator and digital service provider.
Rakuten's distributed cloud network, along with Nokia and Rakuten's work to automate the network build and deployment process, will help reduce network operation costs and enhance operational efficiencies.
Nokia will provide turnkey deployment and integration of the new radio network leveraging a 'zero footprint' site approach with remote radio heads connected to cloud RAN software on the edge cloud, to speed deployment and network scalability.
Nokia is working with Rakuten on several underlying core functions to maximize automation, AI and machine learning to reduce the cost of operations to a fraction of legacy networks.
The network will be deployed across Japan - including Tokyo, Osaka and Nagoya - and use Nokia Cloud RAN, AirScale radios (remote radio heads) and the Nokia AirGile cloud-native core, incorporating technologies such as Nokia IP Multimedia Subsystem, Session Border Controller and Telco Application Server for the fast roll-out of services such as Voice over LTE.
Rakuten and Nokia are completely aligned on the Future X network vision and it is being implemented in Rakuten's brand new mobile network operation in Japan. The building of the network is underway and user trials in Tokyo have already begun.
Yoshihisa Yamada, Representative Director and President of Rakuten Mobile Network, Inc. said: "We are delighted to work with Nokia on co-creating and deploying an open virtualized radio access network. Together, we have managed to disaggregate the current RAN platform by separating hardware and software, and implementing the Radio software as a Virtual Network Function running on Rakuten Cloud Platform (RCP)."
John Harrington, head of Nokia Japan, said: "This is a groundbreaking deployment that is at the forefront of cloud native technology and digital transformation in Japan. By combining the latest technology in cloud and automation with Nokia's hardware, software and services, Rakuten will emerge as the first Japanese service provider to use a full cloud-based service model."
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."
The European Union and Japan finalized common rules to protect personal information, and launched what they called the “world's largest areas of safe data flows”. Firms can transfer data now that the executive European Commission finds that Japanese law offers “a comparable level of protection of personal data,” the commission said.
“This adequacy decision creates the world's largest area of safe data flows,” EU justice commissioner Vera Jourova said, referring to an area of more than 600 million people. “Europeans' data will benefit from high privacy standards when their data is transferred to Japan,” the Czech commissioner said. “Our companies will also benefit from a privileged access to a 127 million consumers' market,” she added.
Jourova said the arrangement "will serve as an example for future partnerships" on data flows and set global standards.
The two sides cleared the final hurdle by agreeing on supplementary rules. These cover the protection of sensitive data, the exercise of individual rights and the conditions under which EU data can be further transferred from Japan to another third country.
Japan's independent data protection authority (PPC) and courts can enforce these rules covering Japanese firms that import data from EU.
Tokyo gave Brussels assurances that any use of personal data for law enforcement and national security purposes would be “limited to what is necessary and proportionate.” Access by public authorities for these reasons would be “subject to independent oversight and effective redress mechanisms,” the EU executive said.
The two sides agreed to a mechanism to investigate and resolve complaints from Europeans over data access that Japan's independent data protection authority will run and supervise. The decision complements the EU-Japan Economic Partnership Agreement, which takes effect in February to become the world's biggest trade deal.
Chinese telecommunications behemoth Huawei has moved swiftly to terminate the contract of an employee who has been arrested in Poland amidst claims he was spying for China.
Huawei executive Wang Weijing was detained by Polish authorities on Friday, following a lengthy investigation that was conducted by Poland’s special services. It is believed that Weijing is a director for the Polish branch of Huawei.
It’s the latest setback for Huawei’s brand globally following the high-profile arrest of the vendors’ CTO, Meng Wanzhou in Vancouver in December. She is fighting extradition to the US, where she stands accused of fraud relating to business activity in Iran.
The Chinese vendor robustly defended its CTO following her arrest and demanded her immediate release from jail. However, Huawei has wasted no timing in trying to distance itself from this latest scandal in Poland by announcing it has fired the employee in question for harming the company’s global reputation.
In a statement given to the Global Times, Huawei said that Wang Weijing was arrested for ‘personal reasons’ and said the incident caused significant damage to the company at a time when it’s under intense scrutiny regarding security.
Huawei cited management rules in company contracts and said it was left with no decision but to terminate its employer relationship with Wang Weijing immediately. Poland has claimed that they firmly believe the Huawei executive was spying for China.
China’s Foreign Ministry responded quickly to the claims made by Polish authorities and expressed that it was ‘highly concerned’ by the arrest. The latest controversy is something Huawei really could’ve done without.
US President Donald Trump is expected to issue an executive order which would ban US companies from working with Chinese vendors ZTE and Huawei over the alleged risk both pose to national security.
In addition to this, Australia and Japan have blocked Huawei from participating in the construction of their super-fast 5G networks, whilst the UK and New Zealand are also considering banning the vendor from the rollout of its 5G networks.
EU spokeswoman Maja Kocijancic refused to "speculate" when asked Friday if there were any concerns about Chinese retaliation.
"We are aware of the reports and we will be indeed in touch with the Polish authorities for further information," she told reporters.
The Japanese government has announced that it will ban telecommunications equipment manufactured by Chinese vendors Huawei and ZTE amidst fears about cybersecurity.
Continental, Ericsson, Nissan, NTT DOCOMO, OKI and Qualcomm Technologies, announced plans to carry out their first Cellular Vehicle-to-Everything (C-V2X) trials in Japan. The objective is to validate and demonstrate the benefits of C-V2X using direct communication technology defined by the 3rd Generation Partnership Project (3GPP) in their Release 14 specifications.
The trials are designed to show the enhanced range reliability and latency benefits of C-V2X direct communications operated in 5GHz band. Additionally, the C-V2X trials are designed to demonstrate the complementary benefits of network-based communications utilizing LTE-Advanced (LTE-A).
The trial results will help develop the ecosystem by providing inputs to the relevant stakeholders, including ITS-related organizations and government agencies, as we prepare for the connected car of the future and the industry’s evolutionary transition towards 5G New Radio (NR), the new global cellular standard being defined in 3GPP.
While complementing other Advanced Driver Assistance System (ADAS) sensors, such as radar, lidar, and camera systems, C-V2X provides non-line-of-sight (NLOS) low latency awareness with longer range and cloud capabilities, and is designed to extend a vehicle’s ability to see, hear and communicate further down the road, even at blind intersections.
C-V2X radio technology, a state-of-the-art cellular technology, is being validated for global deployments, and leverages the upper layer protocols developed by the automotive industry over years of research to support new advanced end-to-end use cases. C-V2X direct communications provide enhanced range and reliability without relying on cellular network assistance or coverage.
Preparation work is well underway with the trial expected to begin in 2018 and the use cases are designed to focus on Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I) and Vehicle-to-Pedestrian (V2P) direct communications, as well as Vehicle-to-Network (V2N) operations over cellular network-based wide area communications with cloud access.
For the field trials, Continental will utilize the Qualcomm® C-V2X Reference Design, which features the Qualcomm® 9150 C-V2X chipset with integrated Global Navigation Satellite System (GNSS) capability to build connected car systems and integrate the systems into Nissan vehicles.
Nissan will perform V2X use case selection and develop test scenarios with key performance indicators (KPIs) for C-V2X technology validation. OKI, one of the leading companies in ITS, will bring their expertise in roadside unit (RSU) infrastructure and applications to demonstrate V2I as a viable technology for advanced traffic applications by integrating the Qualcomm® 9150 C-V2X chipset into their RSU.
Ericsson will join the V2N use case discussion, considering a combination of direct communication and LTE-A network technologies. NTT DOCOMO will provide an LTE-A network and V2N applications to demonstrate the benefits of complementary use of network-based communications for a variety of advanced automotive informational safety use cases.
“We are pleased to be working alongside such a dynamic group of forward-thinking companies to demonstrate the capabilities of C-V2X technology in the first announced Japanese trials,” said Nakul Duggal, vice president of product management, Qualcomm Technologies. “With its direct communications capabilities, C-V2X is ideally suited to be an important factor in facilitating enhanced safety consciousness and driver assistance. This Japan trial is a milestone in the global deployment of C-V2X technology which is expected to be featured in production vehicles by 2020.”
Japanese telecommunications provider NTT DOCOMO announced that it succeeded in 12-channel MMT (MPEG Media Transport) transmissions of 8K video using 5G mobile technology during a test conducted on November 1 at its Yokosuka R&D center in collaboration with Sharp Corporation.
Transmission of compressed 8K video, the next generation of ultra-high definition video, requires a data rate of 80 Mbps on average per channel. In the case of current LTE mobile technology, it is difficult to achieve such a data rate for the stable, multiple-channel transmission of 8K video.
In the recent test, however, ultra-high speed, large-capacity 5G communications using MMT technology successfully transmitted stable multi-channel 8K video with a high bit rate to multiple devices.
Radio waves for wireless communications are constantly influenced by obstacles such as buildings, trees and terrain, as well as reflective objects, so reception errors are inevitable. In the recent test, however, an 8K video receiver with error detection/correction function was used in additional to error correction performed in the wireless layer of the 5G wireless transmission equipment, enabling the 8K video to be displayed with minimal disturbance.
NTT DOCOMO provided the 5G wireless system and video content while Sharp provided the ultra-high definition video transmission/display environment using 8K decoders and 8K displays. Also, the Japan Broadcasters Association supported 8K video encoding and MMT encoding.
Going forward, NTT DOCOMO plans to further test 8K video transmission via its 5G system, targeting commercial services for sports, surveillance, etc. that would deliver high-definition video with MMT-enabled synchronization to diverse devices and displays.
Japanese telecom provider NTT DOCOMO announced that – in a joint trial conducted with MediaTek, a Taiwanese semiconductor company – it has successfully developed a chipset to increase the spectral efficiency of mobile devices by up to 2.3 times compared to existing LTE technology.
The chipset combines DOCOMO's non-orthogonal multiple access (NOMA) radio access technology and MediaTek's multi-user interference cancellation (MUIC) technology, which is required to achieve NOMA.
NOMA multiplexes signals at a base-station transmitter to leverage the increased signal processing capacity of user devices and cancel interference among multiplexed user signals. MUIC removes interference from other users when a base station transmits a signal to a number of users simultaneously.
During the trial, three smartphone-sized devices embedded with the chipsets, each placed in a different location, received data that was transmitted simultaneously from a base station using the same frequency, while the transmission power of the signal transmitted to each device was adjusted.
Using the developed chipset, each device successfully eliminated interfering signals intended for the other devices and received only the intended data, resulting in up to 2.3 times greater spectral efficiency than that of single-user Multi Input Multi Output (MIMO).
DOCOMO is forging ahead with its development of 5G technologies, aiming to increase the signal processing capacities of user devices in populated urban areas and standardize 5G's radio interface and improve spectral efficiency.
Going forward, DOCOMO said it will continue to collaborate with world-leading vendors in its research and development of commercial 5G communications devices and services scheduled to launch in 2020.
iPhone-maker Apple is being sued by a Japanese software company over its ‘animoji’ feature in its latest iPhone X smartphone. The Tokyo-based company Emonster took Apple to a federal court in San Francisco, saying it holds the US trademark on the term ‘animoji’ and that Apple’s use of the word is a blatant infringement.
The iPhone X, scheduled for release in November, features the ability for users to animate facial expressions of ‘emojis’ by utilizing facial recognition technology. The feature was touted as a “great experience” by Apple’s chief marketing officer, Phil Schiller, during the launch of the iPhone X on Sept. 12.
According to the lawsuit made by Emonster, chief executive Enrique Bonasea said the company launched an animated texting app in 2014 called Animoji and registered a trademark on the product, Reuters reported. The lawsuit added that Apple would have been fully aware of the Animoji app because it’s available for download on Apple’s App Store.
Emonster said: “Apple decided to take the name and pretend to the world that ‘Animoji’ was original.” The Japanese firm is seeking damages (unknown amount) and a court order to block Apple from using the term ‘animoji’.
Apple is also locked in a legal battle with chipset maker Qualcomm, with the iPhone maker objecting to Qualcomm’s business model of requiring partners to sign patent license agreements before purchasing chipsets.
The United States International Trade Commission (ITC) commenced an investigation into Apple, Qualcomm recently announced, to examine whether Apple engaged in unfair trade practices by importing and selling certain mobile electronic devices, including iPhones and iPads that infringe one or more claims of six Qualcomm patents.
