VALLETTA, July 14 (Xinhua) -- Malta and Chinese technology giant Huawei signed a memorandum of understand (MOU) on Saturday that will improve Malta businesses via 5G, especially digital infrastructure for smart cities.

The agreement, which was signed by Huawei Technologies Italia CEO Miao Xiaoyang and Maltese Parliamentary Secretary for Digital Economy Silvio Schembri, comes two years after Malta and Huawei signed another MOU that had seen the company test its flagship 5G internet connectivity in Malta.

Speaking at the signing event, Miao said that Malta had already been included in Huawei's global 5G program, noting that the technology would offer greater bandwidth and facilitated mass connections that could eventually be harnessed to create smart cities.

Miao said Huawei wanted to invest more in Malta, particularly in the security and green energy sectors, among others, which he said 5G connectivity could be the key.

Schembri said that through the MOU, Huawei would be committing itself to sustaining academic research with a focus on addressing real world challenges related to public safety, video analytics, data processing and IT systems.

The MOU would also create opportunities through education, starting with an ICT training program for Maltese students at Huawei's training centre in China.

Schembri said he was very happy that Huawei had selected Malta to test its "avantgarde 5G technology", stressing that the collaboration had been of great benefit to both sides.

Schembri said he was also very happy with the excellent relationship that had developed over the last two years between his country and Huawei, adding that the relationship would continue to be strengthened in the years to come.

"We believe it is now time to take the relationship a step further. We believe your expertise in this sector will enhance our ecosystem by entering into further collaboration with our local operators, businesses and citizens," said Schembri.

Huawei May Beat Samsung to 5G in Its Own Backyard
By Sam Kim
July 16, 2018, 4:00 AM GMT+8

While Samsung Electronics Co. has become synonymous with technology in South Korea, a controversial rival could upstage it in the race to build fifth-generation wireless networks in its own backyard.

Huawei Technologies Co., the Chinese company slammed in the U.S. Congress as a security threat, is in the running to supply equipment to all three of South Korea’s national mobile carriers. At stake: initial contracts that could be worth 10 trillion won ($9 billion).

As South Korea pushes to become the first nation to roll out 5G networks, suppliers from around the world are vying to sell switches, base stations and other gear needed to make them work. While Samsung is best known for its smartphones and memory chips, having its equipment shut out of the most advanced wireless networks in its homeland would be a setback for a company that has suffered a number of recent black-eyes.

Huawei has grown to become the largest network gear maker and is pushing deep into 5G technology, investing heavily in research and becoming one of the biggest holders of patents. Its prospects came into focus earlier this year when President Donald Trump blocked Broadcom Inc. from buying Qualcomm Inc. as the U.S. cited risks that the deal could help the Chinese company take the lead in developing next-generation networks.

“Huawei has been aggressive and started development earlier than others,” Park Jin-hyo, executive vice president of SK Telecom Co., said in an interview. “We are looking with an open stance and no bias whatsoever.”

While aware of security concerns surrounding Huawei, Park said South Korea’s largest carrier is looking at other factors including technology and costs, adding the firm wouldn’t be considering the Shenzhen-based company if it fell short of global security standards.

Why U.S. Politicians Are Scared of China’s Biggest Tech Company

SK Telecom and smaller rivals KT Corp. and LG Uplus Corp. have more than 56 million subscribers, a number greater than the country’s population of just 51 million. Cost is a critical factor in deciding their equipment needs after they agreed last month to fork out 3.6 trillion won for 5G wireless spectrum.

LG Uplus has expressed willingness to choose Huawei while SK Telecom and KT are weighing the Chinese company as well as Samsung, Nokia Oyj and Ericsson AB. This week, the country’s technology minister is scheduled to meet with the heads of Korea’s three wireless carriers to go over their 5G rollout blueprint -- a confab at which Huawei will almost certainly come up.

The appeal of 5G technology comes down to its ability to transmit data fast enough to aid the operation of self-driving cars or download feature-length movies in seconds.

While Samsung has never had a huge share of the global market for wireless network gear, it has always been able to rely on hometown support. In Huawei, it faces a competitor that can undercut it on price but also seeks to emulate its reputation for customer service.

“Huawei’s appeal is its price competitiveness,” said Kim Hyun-yong, an analyst at Ebest Investment & Securities Co. “And it has a lead with its 5G devices developed well enough to be put to work immediately.”

Still, questions remain about Huawei and security. The company was founded in 1987 by a former Chinese military officer and it says it’s now owned by workers. But the U.S. has accused it of maintaining close links to the government and enabling spying by the mainland. It’s effectively been blocked from selling network equipment to the biggest U.S. carriers and struggled to get support for its mobiles in the country.

Security allegations resonate in South Korea, which is a U.S. ally hosting almost 30,000 American troops but at the same time needs China’s support to remove nuclear arms in North Korea. Petitions have appeared on the South Korean presidential website seeking to ban Huawei from the country, which after becoming the first major market to reach full 4G coverage wants to extend that to 5G.

Huawei didn’t respond to an emailed request for comment. Samsung declined to comment.

Huawei’s success in winning network contracts has seen it push heavily into consumer devices and it’s now the third-largest smartphone vendor, behind only Samsung and Apple Inc. While Samsung still enjoys a lead over Huawei in smartphones, that edge is shrinking. The maker of Galaxy phones had a 21.9 percent share while Huawei had 10.8 percent last year, according to TrendForce.

5G is important to Samsung, which seeks to boost its profile as a supplier of networking equipment by doing well in countries tapping the next-generation spectrum early, such as South Korea and Japan.

Samsung is already being challenged in its components businesses as Chinese rivals seek to catch up in televisions and memory chips, two sectors where the Suwon-based company is the world’s biggest.

“Supplying 5G equipment in a country that’s going to be the world’s first to go 5G has enormous symbolism to it,” said Hong Een-kee, a professor of wireless communications at Seoul’s Kyung Hee University. “Huawei stays competitive globally because it has a solid grip at home. Imagine what it’d mean if a South Korean company lost in its own backyard when it’s trying to raise its own share of the global market.”

Source: Xinhua| 2018-07-23 16:39:06|Editor: ZX


BEIJING, July 23 (Xinhua) -- China has granted the official greenlight for virtual telecom operator businesses after piloting the practice for almost five years.

The Ministry of Industry and Information Technology has issued official licenses to 15 private virtual telecoms to resell internet access, the ministry said in a statement released Monday on its website.

These virtual operators, including Chinese tech giants Alibaba and Xiaomi, do not maintain the network infrastructure but rent wholesale services like roaming and text messages from the country's three major telecom infrastructure operators China Mobile, China Unicom, and China Telecom.

In a move to further open up the telecom sector, China started to issue pilot licenses in 2013 to private companies to allow them to offer repackaged mobile services to users. A total of 42 Chinese enterprises received pilot licenses to operate virtual telecom businesses.

Granting virtual telecom operators official licenses is aimed at encouraging mobile telecom business innovation and improving the sector's overall service quality, the statement said.

Beijing enters 5G era
China.org.cn, August 14, 2018

At 10 a.m. on Aug. 13, Beijing officially entered the 5G era as a live video was projected onto the big screens in the Beijing Unicom Building.

The new generation wireless data network is being introduced by China Unicom, one of the major telecommunications carriers in China. According to a staff member at the company's Beijing branch, the 5G network could be used to transmit 4K high definition (HD) signals, with sharpness 16 times higher than what could be transmitted through 4G. The staff member said 5G-capable mobile phones will become available in the first half of next year, and China Unicom will begin recruiting field testers.

According to a person in charge at the Beijing branch, China Unicom has built four 5G base stations in Beijing, and it is aiming to finish building experimental networks for testing, application incubation, and business promotion by the end of this year. The 5G base stations will first cover some key areas in the Chinese capital such as its subsidiary administrative center, the new airport, Chang An Avenue, Finance Street, the International Horticultural Exposition Area, and the 2022 Winter Olympic Park. The Beijing International Horticultural Exposition will be the first event in the city to use the 5G network.

According to reports on China's timetable for developing the 5G network, the country plans to kick off test runs this year, pilot commercial uses in 2019, and realize large-scale commercial expansion in 2020. To compensate for the small number of 5G base stations at the beginning, 4G and 5G networks will coexist for a couple of years in Beijing. This means that telecom companies will continue to service 4G mobile phones, and that 5G-capable phones will be backward-compatible with 4G signals.

Officials from the Beijing Municipal Communications Administration said that they have worked out schemes to speed up the overall planning and construction of 5G capabilities in Beijing. Meanwhile, the Beijing Municipal Commission of Economy and Information Technology will be working to promote the 5G information and communication industries by supporting network carriers to develop 5G model applications for driverless vehicles, healthcare services, industrial networks, smart cities, and ultra HD videos. Already, the Beijing branch of China Unicom has started collaboration with Baidu and other companies in such fields as driverless vehicles and big data.

WUHAN - High-speed 4G network has been installed in an iron mine 500 meters deep in Central China's Hubei province to improve mining safety and production efficiency.

"Miners are able to send photos, videos and voice messages from underground via 4G network, so that experts can give instructions and solve problems from the control center," said Sun Baoping, an engineer at Chengchao mining company, a subsidiary of Wuhan Iron and Steel Group.

Most Chinese mines now use 2G networks for underground telecommunications, which can not meet the needs for the use of more information technology in the mining industry, Sun said.

Sealed barrels were used to contain optic cables to avoid spark-triggered explosion in gas-rich mine shafts, and antennas were integrated and kept in remote radio units to stay away from dusts and enhance signal, said Zhang Liang from China Mobile's Ezhou city branch.

So far 4G signals have covered three tunnels of the iron mine, providing better telecommunication service, improving the efficiency of production and emergency rescue, and facilitating the use of "intelligent mining" technology in the future, Sun said.

Huawei helps Italian telecom carrier launch first 5G base station
The launch of the first 5G base station in Italy, which featured Chinese telecom equipment producer Huawei's end-to-end (E2E) 5G equipment, marked a milestone in 5G cooperation between China and Europe.

It also served as a rebuttal to some Western countries' ban on Chinese devices over alleged security concerns, an expert said.

Huawei helped Italian telecom carriers TIM and Fastweb launch the country's first 5G base station in compliance with 3GPP standards and put it into commercial use, according to a statement on Huawei's website on Tuesday. The station uses Huawei's E2E 5G equipment.

The partners also demonstrated several user cases as part of their cooperation, including smart city and transport uses, virtual reality and augmented reality, as well as smart culture and tourism, the statement noted.

Xiang Ligang, chief executive of telecom industry news site cctime.com, told the Global Times Wednesday that the partnership shows the huge potential of cooperation between China and Europe in the 5G industry.

Chinese firms have participated in the construction of 4G networks in many countries and "developed a deep understanding of the local situation."

"European carriers, taking account of the cost and their limited budget, will expand their 5G networks based on 4G infrastructure. So choosing a long-term partner could help the local operators to transit more smoothly from 4G to 5G," Xiang said.

Bids from Chinese firms, compared with other rivals, are more cost-effective while ensuring competitive technology as well as responsive and good services, Xiang said.

Xiang added that the collaboration demonstrates the safety of Chinese telecoms equipment.

"Otherwise, why would Italy choose to work with a partner that would allegedly 'threaten its national security'?" Xiang asked, suggesting that the US and Australia should not politicize business deals.

Huawei ships 10,000 5G base stations globally
By Wang Yi Source:Global Times Published: 2018/11/21 22:43:41

China expected to lead development of next-generation services: analysts

Domestic technology giant Huawei has urged operators to trust its fifth-generation (5G) vision as it has shipped over 10,000 base stations globally, which experts said shows that China is expected to lead the game in 5G network development, because all links in the nation's industry are strong.

Huawei has told operators its 5G connections have achieved milestones in development and commercialization is also accelerating.

"154 mobile operators in 66 countries and regions around the world are conducting 5G technical testing or field testing. Huawei has shipped more than 10,000 5G base stations to customers around the world," said Ken Hu, rotating chairman of Huawei, at the Huawei Mobile Broadband Forum (MBBF) in London on Tuesday, according to the press release Huawei sent to the Global Times Wednesday.

"5G is still in the testing phase now, and large-scale commercialization is expected in the second half of 2019," Xiang Ligang, chief executive of Chinese telecoms industry news website cctime.com, told the Global Times Wednesday.

"The number of 10,000 5G base stations is just a beginning. By 2025, millions of 5G base stations are expected to be built across the world," Xiang said.

"According to GSMA figures, 110 markets in the world will deploy 5G facilities," said Hu at the MBBF. "5G innovation is bringing information and communications technology to a whole new level. Revolutionary change is expected to be seen in all walks of life in the coming 5G era."

GSMA, or GSM Association, is a trade body that represents the interests of mobile network operators worldwide.

Xiang said that transformation caused by 4G has already been reflected in all walks of life, and the 5G world will be more intelligent. All things will be connected by the network.

"China is already leading 4G development," Xiang said. "We have witnessed and lived through the great transformations of bicycle-sharing, online car-hailing and mobile payments, which are all based on 4G technology."

"5G is ready in three key areas of availability, economy and application," Hu said. "However, 5G has met obstacles in terms of spectrum and site resources."

Hu called for governments across the world to coordinate and open wide bandwidth 5G spectrum and make more public resources available for site deployment.

Governments are expected to support 5G development, Xiang said, because the technology will benefit economic development and social management.

Liu Dingding, a Beijing-based technology analyst, agreed that spectrum and site resources will not be a problem holding 5G development back.

"The same concern of resources waste and overlapping construction was raised when the 4G era came, but the resources distribution was optimized in the end.

"Because the advantages outweigh the disadvantages, governments and relevant departments will offer support."

As some countries, like the US or Australia, have already banned Chinese companies from their 5G infrastructure building effort, MBBF has attracted operators and partners from Europe, the Mideast and the Asia-Pacific, according to the Huawei press release.

In terms of 5G technology development, China and the US are at about the same level, Xiang said.

"Huawei has not entered the US market, but in the future, it may have a chance to get into Australia," Xiang said. "Even in the US, there are operators and consumers who want to buy Huawei's equipment and devices."

China's 5G development is promising, because all links in the industry are strong, Xiang noted. "We have good telecom operators, device manufacturers and mobile internet developers."

"Take 5G mobile phones as example. Chinese companies will lead the game, and based on the open information, Huawei is the first company in the world that has delivered 10,000 5G base stations," Liu said.

New technology developed at CityU saves at least 4.5% of energy in mobile networks
Kenix Wong

​

(From left) Mr Stephen Chau, Dr Eric Wong Wing-ming, and Professor Henry Chung Shu-hung.

A research project conducted by the Department of Electronic Engineering (EE) at City University of Hong Kong (CityU) has developed technology that can optimise mobile network design and reduce the energy consumption of the base stations by a minimum of 4.5%. If all the base stations in Hong Kong adopt this technology, the energy saved could be enough for at least 5,000 households per year as electricity.

As it is estimated that the energy consumption of the base stations will increase due to high volume data in future, the team has started to look at ways of applying this newly developed technology for the new mobile network in the near future.

“Base stations account for 70 to 80% of total energy consumption of a mobile network. They contain radio transceivers which maintain communication between the network and the mobile users through radio links. Most of the time, many base stations are not heavily loaded even though they consume a lot of energy. Hence there is huge energy waste, especially during low-traffic hours,” explained Dr Eric Wong Wing-ming, Associate Professor at EE, who leads the research.

“Everyone knows it is energy-saving to let the transceivers go into sleep mode, a low-energy-consumption mode, when not in use during low-traffic hours. However, the sleep mode of the base station causes a reduction in the total available capacity of the network, and so the quality of service may be degraded. Hence, we need to decide how to halt and how many transceivers that we can halt so that the quality of service would not be sacrificed from a macro and systematic perspective,” said Dr Wong.

With funding from the government’s Innovation and Technology Fund (ITF) and technical support from SmarTone, the team has developed technology to efficiently evaluate the trade-off between quality of service and power consumption in a cellular network with the base station sleeping. The new technology estimates power consumption based on realistic traffic data and energy models, and then evaluates the quality of service by using the accurate and computationally efficient analytical technique called Information Exchange Surrogate Approximation for Cellular Networks (IESA-CN), which has also been developed by the team.

​

Dr Wong explains how the new technology can help save the energy consumption of the base stations.

“The advantage of IESA-CN is that it is much faster in computation than using computer simulation, a traditional evaluation means to assess the quality of service,” explained Dr Wong. “In terms of computational efficiency, the running time of IESA-CN (about 0.2 second) is over 50,000 times faster than that of simulation (about 3 hours). Given its reasonable level of accuracy, our proposed IESA-CN can be used for searching for optimal solutions to trade-off between power consumption and quality of service in cellular networks.”

With several rounds of testing at different scales of base stations, Dr Wong said the new technology could help save energy consumption of the base stations by at least 4.5% while maintaining service quality at a satisfactory level. The team estimated that if all the base stations in Hong Kong adopt this technology, the energy saved could be enough for at least 5,000 households per year as electricity. He added that the software could help mobile network operators optimise the network design and hence save energy consumption based on the service quality they want to provide.

“As a leading mobile network operator, SmarTone has been supporting academic research and promoting the development of novel technology in the utilisation of network resources to pave the way for future network development, and to contribute to environmental protection,” said Mr Stephen Chau, Chief Technology Officer of SmarTone. “In providing technical support to the Department of Electronic Engineering at CityU through the ITF project, we can get a more accurate picture of the electricity consumption characteristics and patterns of the base stations. This will enable our technical team to attain higher energy efficiency when planning network resources in the future, and to promote green energy.”

Dr Wong pointed out that in the near future, the number of the base stations and the consequent energy consumption would increase when the new generation of mobile network is adopted. The problem of energy waste, as compared with that of the 3G and 4G networks, will be even more serious. The team is now conducting research to enhance the application of this newly developed technology. Dr Wong believed that the capacity of the new technology to save energy would be even more notable when it is widely adopted in the new mobile network.

China steps up deploying IPv6-based network

2019-05-04 09:32:25 Xinhua Editor : Mo Hong'e

China is accelerating the deployment of the Internet Protocol version 6 (IPv6)-based network, according to the Ministry of Industry and Information Technology (MIIT).

China will launch a special campaign to upgrade the network infrastructure, improve IPv6 service and make the terminal equipment better support IPv6, said an official with the MIIT. "We decided to finish transforming 13 internet backbones to the IPv6 network by the end of 2019."

The country will strengthen the security in the IPv6 network and support relevant companies and institutions to carry out research on the prevention of risks in the IPv6 network in emerging industries, including the Industrial Internet, Internet of things and car networking, the ministry said.

The IPv6 is considered the next generation of the internet, allowing much higher theoretical limits on the number of IP addresses than the current IPv4 system.

China in 2017 issued a plan to encourage large-scale adoption of the IPv6 network. According to the plan, by the end of 2025, network and terminal devices will fully support the adoption of IPv6 in China, and it will have the largest number of IPv6 users in the world by the end of 2025.

中国新一代物联网开始落地建设

新一代物联网（以下简称“物联网”）是全球第二套计算机通讯网络系统，能全球兼容运行互联网，是由我国多个机构历时20多年潜心研发和实用化而来。我国已经自主建成物联网1条母根，13条主根（N-Z根），开始向全球提供IP地址，并能全面寻址、域名解析，实现跨国界、跨语言、跨系统的通信。

2014年12月4日，经过世界各国多年竞争博弈后，ISO/IEC国际标准组织在其发布的未来网络国际标准中（国标委外函[2014]46号）正式确认：由中国主导未来网络的《命名与寻址》、《安全》等核心标准的制定，并由中国拥有核心知识产权。目前，中国新一代物联网是唯一符合“国际未来网络标准”的计算机通讯网络，代表着新一代互联网的发展方向。值得注意的是，由于英文只有26个字母，分别被中美各13条根服务器占用(首字母索引)，导致世界上难以产生第三套计算机通讯网络系统。

新一代物联网抛弃了传统互联网的底层架构及缺陷，其网址基本长度为256位（预留至1024位），其中保留128位用于兼容互联网，实际新增2^128个有效网址，能满足未来700年发展的网址需求。未来太空移民时，再启用预留的网址。物联网采用先认证再通讯、地址可加密等新技术，有效解决互联网的安全架构缺陷。

新一代物联网真正实现了万物互联（Internet of Things 简称IoT），其能为带电的物分配一个专属静态IP地址，可通过网络进行解析和联结；也能给不带电的物分配一个专属的物联网编码（RFID电子标签），可通过网络进行解码和查询。我们可以把物联网编码理解为一个简单的IP地址，其对应的是一串简单文本构成的信息链。例如一个苹果，消费者扫一扫其物联网编码，就能显示这个苹果相关的种植、施肥、采摘、包装、售价、发货、运输、签收、购买者、相关日期等信息链。一些厂家宣称已研发出不用IP地址的IoT，这些都是伪IoT，原理无非是构建一个类似聊天群的通讯系统，为每个设备分配一个号，通过添加好友的模式进行物物联结。这些伪IoT只能在自己的软件系统内运行，一旦跨系统，就无法互联。

我国建设和使用物联网，不仅可以节约巨额的互联网使用费，还可以向全球输出更具性价比的物联网服务，进入互联网最具价值的领域，获取巨大的经济利益。随着物联网的建设和使用，我国将能对网络进行大幅度提速、降费，惠及广大人民和企业，极大促进我国网络应用市场和相关产业的蓬勃发展。

由于互联网是虚拟的，极其容易被利用进行违法犯罪活动和网络攻击。近年来，利用互联网虚拟特性进行诈骗的事件层出不穷。另根据中国国家互联网应急中心抽样检测显示： 2011年，有近5万个境外IP网址作为木马或僵尸网络控制服务器，参与控制了我国境内近890万台主机，其中有超过99.4%的被控主机，源头在美国。新一代物联网通过先认证再通讯、网络地址加密等新技术，可以有效打击电信诈骗和抵御网络攻击。未来基于区块链技术的数字经济（如国家数字货币）的关键应用，目前还只有新一代物联网具备支撑能力。

截止目前，新一代物联网在系统技术、知识产权、国际标准、国家政策、软硬件、服务能力等方面都已充分准备就绪。新一代物联网商用平台已经落地，开始为商用物联网提供根服务、IP地址发放、域名解析等底层网络服务。

新一代物联网应用

新一代物联网“.chn”已得到国家机构、国企等带头应用，并获得北斗系统、诚平商城等平台实用化验证，打破了国外对全球定位、精准授时、互联网根服务等核心技术的垄断。诚平商城是原产者专属的物联网+新电商，以物联网产品编码为去假存真手段，以线下60万个社区和村级服务站的大学生为抓手，为原产者电商赋能，让5亿原产者直供产品多卖钱，让12亿消费者直采商品少花钱，很快将形成十万亿级的无假货新电商生态圈。物联网的商用序幕已经拉开，物联网产业开始进入蓬勃发展的新时代。
