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.
Ericsson, PS Solutions Corp. (affiliated with SoftBank Group Corp.), and CKD Corporation, a supplier of actuation products, are collaborating on an update to “e-kakashi”, a platform which applies artificial intelligence (AI) and Internet of Things (IoT) technologies into agricultural processes. First introduced by PS Solutions in 2015, the second-generation “e-kakashi” platform will launch in March 2018.
“True collaboration is the only way to bring real automated IoT uses cases to life,” said Mikael Eriksson, Head of Ericsson Japan. “The combination of PS Solutions’ experience, applications and insight in the industry, along with the advanced features provided by Ericsson IoT, will create positive change for agriculture."
An IoT scarecrow with an AI brain
The Japanese word kakashi translates to scarecrow, but PS Solutions' “e-kakashi” does much more than frighten off pests. With a powerful combination of AI, IoT and cloud technology, “e-kakashi” is designed to maintain an ideal environment for almost any crop to grow in. Japanese manufacturer CKD Corporation, a pioneer in actuation, provides the electro/pneumatic devices that allow the IoT machinery to be controlled remotely.
Easy onboarding of agricultural IoT machinery
The “e-kakashi” platform can easily integrate new IoT devices as agriculturalists need them. Through the Zero Touch Onboarding functionality of the Ericsson IoT Accelerator platform, devices are immediately accessible after installation. No physical control panels are needed, as all functions are handled in the cloud.
Zero Touch Onboarding, which allows devices to be onboarded to the IoT Accelerator platform and then managed through their lifecycles with ease, uses the Open Mobile Alliance Lightweight Machine to Machine (a protocol from the Open Mobile Alliance for machine-to-machine or IoT device management) and smart objects from The Internet Protocol for Smart Objects (IPSO) Alliance. These are complements to cellular IoT connectivity.
PS Solutions will use Ericsson IoT Accelerator’s building blocks with SoftBank’s cellular connectivity, which is also powered by Ericsson. Incorporating data on variables such as temperature, humidity and precipitation, “e-kakashi” uses AI to automatically optimize growing conditions. For example, to maintain the ideal temperature for growing tomatoes, “e-kakashi” adjusts greenhouse ventilation accordingly.
Using an intuitive app from PS solutions with comprehensive data visualization, the “e-kakashi” user can modify the AI-based standard settings to apply their own professional know-how.
The current solution monitors temperature, humidity, CO2 and other conditions, and guides what actions to take next based on the AI engine. With the support of analytics from Ericsson IoT Accelerator, the next generation of “e-kakashi” will enable higher automation by connecting with actuators.
Ericsson expanding IoT possibilities in Japan
Ericsson IoT Accelerator gives operators a low cost, reliable method to support enterprise IoT with a large number of connected devices.
With the rapid growth of IoT, there are great opportunities for operators to expand revenue with new services. PS Solutions' parent company, network operator SoftBank, has partnered with Ericsson to expand networks and increase IoT revenue streams in Japan. In April 2017, SoftBank began rolling out Ericsson solutions to support the deployment of cellular IoT services across Japan.
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.
Japan’s SoftBank and Huawei Technologies Japan teamed up to demonstrate various potential use cases for a 5G network to SoftBank’s business partners. The use cases included ultra-high throughput, ultra-low latency transmission, and edge computing.
The demonstration included real-time UHD video transmission using ultra-high throughput, remote control of a robotic arm using ultra-low latency transmission, and remote rendering via a GPU server using edge computing. The real-time UHD video transmission demonstrated throughput of over 800 Mbps. Also, the remote control of the robotic arm demonstrated an ultra-low latency one-way transmission of less than 2ms.
SoftBank is planning various experiments to study 5G technologies and is endeavoring to launch 5G commercial services around 2020.
Real-time UHD video transmission
For the real-time UHD video transmission demonstration, a UHD camera was installed inside the demonstration room to capture outdoor scenery. The data from this camera was then compressed in real-time using an encoder and transmitted through the ultra-high throughput 5G network to a UHD monitor via a decoder, where the original data was recovered.
In this demonstration, the scenery of the Odaiba Tokyo Bay area was successfully displayed on the UHD monitor using the ultra-high throughput provided by the 5G network. This technology can be applied to various industries, including tele-health or tele-education.
In the immersive video demonstration, scenery was captured by a 180-degree camera equipped with four lenses pointing four different directions installed in the demonstration room, and captured scenery was distributed to smartphones and tablets over the 5G network.
Four separate cameras were set up to capture the scenery in different directions, and the video images captured by these cameras were stitched together to generate a 180-degree panoramic video image that enabled multiple simultaneous camera views.
Then the video image was compressed and distributed to smartphones or tablets in real-time over the 5G network, which gives users a truly realistic user experience. Coupled with a 5G network, this technology can be applied to virtual reality (VR) or augmented reality (AR).
Remote control of robotic arm with ultra-low latency
For the remote control of robotic arm with ultra-low latency demonstration, a robotic arm played an air hockey game against a human in this demonstration. A camera installed on top of the air hockey table detected the puck's position to calculate its trajectory.
The calculated result was then forwarded to the robotic arm control server to control the robotic arm. In this demonstration, the robotic arm was able to strike back the puck shot by the human player on various trajectories. This technology can be applied to factory automation, for example.
Remote rendering by GPU server
Remote rendering by GPU server was also demonstrated. Rendering is a technology used to generate videos or images using computers with GPUs (Graphic Processor Unit). This technology is used for generating HD videos in computer games or for CAD (Computer Aided Design).
The rendering consumes a large amount of computing resources. Therefore, HD computer games or HD CADs were not executable on tablets or smartphones on their own. However, edge computing technology provided by the 5G network allows us to enjoy HD computer games or HD CADs on tablets or smartphones.
A GPU server located near a 5G base station performed rendering and the image generated by the GPU server was sent to the tablet over the ultra-high throughput and ultra-low latency 5G network. This technology can be applied to check the CAD data at a construction site with a tablet or to enjoy an HD game application on a smartphone.
Japan launched its third geo-positioning satellite into space on August 19, bringing the country closer to its goal of implementing a global positioning system (GPS) like the United States, to provide information for auto-piloting and also national security purposes.
An H-2Q rocket carried a geo-positioning satellite into orbit after a week-long delay, Japan’s government said, due to a technical malfunction. More satellites will be launched by the end of the year, the government said, to begin providing accurate position information by April next year.
Japan’s minister in charge of space policy, Masaji Matsuyama, said in a statement, “With the success of the third satellite, we have made another step closer for having signals from four satellites in the future.”
Mitsubishi Electric Corp. manufactured the satellite and was sent to space by Mitsubishi Heavy Industries Ltd. The government has set a target for 2023 to increase the number of its geo-positioning satellites, to make its system independently operational in case the US GPS becomes unavailable for some reason.
