China's 4G technology to go global

[streetcry]

China's homegrown fourth-generation (4G) telecommunication technology is expected to go global and be widely adopted by 2015, with countries in Africa and Latin America the most likely to use the technology, according to industry experts.

The Time Division-Long Term Evolution (TD-LTE) technology is the next-generation telecommunication standard that China Mobile Communications Co is promoting.

Under ideal conditions, TD-LTE can easily reach download speed of more than 150 megabytes per second, much faster than third-generation (3G) TD-SCDMA technology.

"Many international operators have contacted China Mobile and expressed a willingness to adopt TD-LTE networks," Chen Jinqiao, deputy chief engineer at the China Academy of Telecommunication Research (CATR), told China Daily.

He said the most likely partners in building TD-LTE networks may come from Africa and Latin America, as many countries on those continents have a good relationship with China both economically and politically. "They are more likely to accept China's technology, and TD-LTE may even help them make a leap forward directly from the 2G era to the 4G stage," Chen said.

The sound development of TD-LTE is important. The successful use of the technology in China will increase confidence in the product, remove any doubt overseas operators may have, and encourage them to deploy TD-LTE networks, according to Chen.

Along with a number of other European telecom carriers, Poland's mobile operator Aero2 announced in November that it would build the world's first commercial TD-LTE network as early as this year. China Mobile, the world's biggest wireless operator by subscribers, said 15 TD-LTE trial networks have already been deployed in a number of countries.

Another nine test networks, in cooperation with global telecom operators, will be added during 2011, said Wei Bin, chief of the network research department with the China Mobile Research Institute, at a forum.

However, in mature markets, the promotion of TD-LTE technology will be difficult, since competition from other 4G technologies is harsh, said Chen of the CATR.

China Mobile is pinning great hopes on the new technology, as the company intends to use it to snatch market share both at home and overseas.

Its upgraded version, called TD-LTE Advanced, was selected as one of six international 4G standards by the International Telecommunication Union (ITU) in Chongqing municipality in October.

It's predecessor, TD-SCDMA, failed to achieve that goal because it was inferior to rival 3G technologies such as WCDMA in terms of maturity, according to analysts, and its use was limited to within China.

The globalization of TD-LTE technology is proceeding well, and almost all the major international telecom companies have pushed forward its development, said Tina Tian, chief telecom analyst with Gartner's China office.

Foreign telecom giants such as Ericsson and Alcatel Lucent, as well as domestic companies such as Huawei, ZTE and Datang, have participated in technical trials of TD-LTE technology with China Mobile since the end of 2008.

Moreover, the Ministry of Industry and Information Technology announced on Friday that it had approved wide-ranging tests of TD-LTE technology in six major Chinese cities, indicating that the technology is edging towards the commercial-use phase in China. The six cities are Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen and Xiamen. However, a specific timetable for the pilot was not revealed on Friday.

China Mobile said in a statement on Friday that the upcoming large-scale tests are aimed at exploring the commercial potential of the technology, and to provide impetus for international telecom carriers to adopt and deploy the new network.

Gartner's Tian said that China Mobile may also use the chance to enhance its dominant position in the domestic industry.

"Compared with China Unicom's WCDMA and China Telecom's CDMA2000, China Mobile's TD-SCDMA did not gain the upper hand in the 3G market, so the company has quickened the pace of promoting 4G technology in the hope of maintaining technology superiority," Tian said.

China announces nuclear fuel breakthrough

Chinese scientists have made a breakthrough in spent fuel reprocessing technology that could potentially solve China's uranium supply problem, Chinese television reported on Monday.

The technology, developed and tested at the No.404 Factory of China National Nuclear Corp in the Gobi desert in remote Gansu province, enables the re-use of irradiated fuel and is able to boost the usage rate of uranium materials at nuclear plants by 60 folds.

"With the new technology, China's existing detected uranium resources can be used for 3,000 years," the China Central Television reported.

China, as well as France, the United Kingdom and Russia, actively supports reprocessing as a means for the management of highly radioactive spent fuel and as a source of fissile material for future nuclear fuel supply.

But independent scientists argued that commercial application of nuclear fuel reprocessing has always been hindered by cost, technology, proliferation risk and safety challenges.

China has 171,400 tonnes of proven uranium resources spread mainly in eight provinces -- Jiangxi, Guangdong, Hunan, Xinjiang, Inner Mongolia, Shaanxi, Liaoning and Yunnan.

China is planning a massive push into nuclear power in an effort to wean itself off coal, the dirtiest fossil fuel. It now has 12 working reactors with 10.15 gigawatt of total generating capacity.

China has set an official target of 40 gigawatts (GW) of installed nuclear generating capacity by 2020, but the government indicated it could double the goal to about 80 GW as faster expansion was one of the more feasible solutions for achieving emissions reduction goals.

As such, China will need to source more than 60 percent of the uranium needed for its nuclear power plants from overseas by 2020, even if the country moves forward with a modest nuclear expansion plan, Chinese researchers say.

China wows world with engineering

The country surprised the world with its engineering and technical feats in 2010, when it completed several monumental projects high in the sky, deep in the seas and in-between.

China last year completed 15 successful space launches, including that of its second lunar probe, Chang'e-2, which will determine a site for the country's first unmanned moon landing around 2013.

The Long March launch vehicles also sent five Beidou navigation satellites into orbit. The launches were part of the country's plan to have 12 Beidou navigation satellites form a network covering the Asia-Pacific region before 2012. The system will have 35 navigation satellites by 2020, when it will rival the United States' Global Positioning System.

On the ground, China became a strong player in the global high-speed railway industry in 2010 by innovating upon technologies previously imported from Germany, France and Japan.

The Ministry of Railways announced the nation's high-speed railway network last year reached 7,531 km, becoming longer than any other countries'.

The network's top service speed became the world's fastest at 380 kilometers an hour since the Shanghai-Hangzhou high-speed railway opened in October.

It set new operation speed records twice in 2010.

In September, a China-made fast train reached 416.6 km an hour on the Shanghai-Hangzhou high-speed railway. Two months later, a train on the 1,318-km-long Beijing-Shanghai high-speed railway beat that record by reaching 486.1 km an hour.

Sources with CSR Corp Ltd, a major domestic train manufacturer, said in December that an experimental train is being developed that would challenge the 574.8 km an hour speed traveled by a specially configured version of France's TGV in 2007.

The country also made great achievements in the deep sea, becoming the fifth country to develop deep-diving technology capable of going beyond the 3,500-meter mark.

The domestically developed submersible Jiaolong planted a Chinese flag on the bottom of the South China Sea during a 3,759-meter-deep dive in July.

The vessel, designed to reach a depth of 7,000 meters and operate in most of the planet's oceans, is considered the world's only manned submersible that can theoretically reach those depths. Japan's Shinkai 6500 can dive for 6,500 meters. The other three countries with deep-diving technology are the United States, France and Russia.

And 2010 was the year China overtook the United States in developing the fastest supercomputer.

The Tianhe-1A can perform 2,507 trillion calculations a second and is 29 million times faster than the earliest supercomputers.

In addition, the water level of the largest hydroelectric project, the Three Gorges Dam, had increased to 175 meters as of October 2010, enabling it to generate electricity at maximum capacity.

The slew of mega-projects were made possible by the country's mammoth spending on research and development.

According to the Paris-based Organization for Economic Cooperation and Development (OECD), China's investment in innovation nearly doubled from 34 billion euros ($44.56 billion) in 2006 to 65.7 billion euros in 2009.

That's a big compliment! The Cinese will love it. However Chinese are not the only ones very good at overhyping. I think the Indians and the Americans are masters of the game; master trumpeteers and masters of deceit and deception too! The Chinese have alot to catch up in this department!

Is the important to know who/whose created the 4G. The most important is can anyone market it in affordable price for the consumer if not the product will never take off.

 

[longbow]

A great point! At the end of day it is implementation, how wide it is used and cost. There are many competing systems out there. I doubt if any standout as truly superior. What matters is implementation and number of users. If the system has many users, the company will continue to improve and invest in R&D to improve the technology. Also, with use bugs will be worked out and companies will understand what are the potential issues.

Lets talk about cellphones, with Chinese market + Indian market (Chinese are selling and finance the technology to India) + Brasil + Africa + Latin America this could easily become a standard tech.

The days of pure research without commerical application are over. In the past where you had huge telephone monopolies, the companies could fund a multi billion dollar research facility. This is no linger the case.

Going forward we can see Chinese companies use their size as a result of their huge domestic market to gain international market share.

If you look at the recent $100B trade deal between China and India, you see numerous projects where Chinese firms sell and implement their technology in india and the Chinese banks offer the financing.

The German and Jap banks have been doing the same for years but in this case the Chinese have huge market scale.

Whether its 4G, 5G, 6G or 10G, when it comes, I as a consumer just subscribe and use. :o

Agreed.
China sent a man into space 50 years late and yet rejoiced over the moon (pardon the pun)

 

[zuoom]

have they resolved the power consumption issue already?

last i remember the mobile phone can be as small as the current phones. but it require a power brick to power the thing for long. otherwise battery can only last like a hour or two.

Well, it remains to be seen.

If Qualcom, Motorola, Intel etc discover their design has been copied,
or their patents on LTE and WiMAX tech has been infringed,
( They have literally hundreds of such patents on this technology )
then the China 4G will face tough law suits in USA, Europe, Canada,
Australia, Japan, India and many other places where rule of law is
strict and enforced. even African nations will feel the heat to fall
in line via WTO rulings.

In that case, no matter how competitive the China 4G pricing is,
it will be of no use.

A recent case was the German SAP, which had to pay Oracle
1.4 billion dollars as compensation in a US court ruling for infringing
Oracle's rights.

Chinese jet fighter 'sighting' raises fears over region's military power balance



J-20.jpg (29.01 KB)
2011-1-6 12:02


Photos leaked online appear to show a prototype of China's J-20 stealth fighter jet





A photograph of what is reported to be a new Chinese stealth fighter and "carrier-killer" missile has prompted concerns that a tilt in the balance of military power in the western Pacific towards China may come sooner than expected.

The emergence of the hi-tech weaponry - which would make it more difficult for the US navy and air force to project power close to Taiwan and elsewhere on China's coastline - comes at a politically sensitive time. Later this month, President Barack Obama and his Chinese counterpart, Hu Jintao, will hold a summit in Washington aimed at patching up their differences after a niggling year in bilateral relations.

The photograph, of what appears to be a prototype J-20 jet undergoing runway tests, has been circulating on the internet since last week, fuelling speculation that China's fifth-generation fighter may fly ahead of forecast.

The defence ministry has yet to comment on the image, which seems to have been shot from long-distance near the Chengdu aircraft design institute. The photographer is also unknown, which has added to the mystery about its origins and authenticity as well as the motive of the distributor.

But defence analysts believe this is the first glimpse of the twin-engined, chiselled-nosed plane that mixes Russian engine technology with a fuselage design similar to that of the US air force's F-22 "stealth" fighter, which can avoid detection by radar.


If confirmed, it would be an impressive step forward for the Chinese air force, which until now has largely depended on foreign-made or designed planes. "I'd say these are, indeed, genuine photos of a prototype that will make its maiden flight very soon," said Peter Felstead, the editor of Jane's Defence Weekly.

The J20 is likely to be many years from deployment, but the US defence secretary, Robert Gates - who visits Beijing next week - may have to revise an earlier prediction that China will not have a fifth generation aircraft by 2020.

It is not the only challenge to US superiority in the region. China has refurbished a Ukranian aircraft carrier and wants to build its own by 2020.

A more immediate threat is posed by China's adaptation of an intermediate-range ballistic missile - the DF-21D - to target US aircraft carriers. This project is also further advanced than previously believed.

Admiral Robert Willard, the US navy's commander in the Pacific, warned last month that the weapon - nicknamed the "carrier killer' - had reached "initial operational capability". Faced by this threat US battle groups are likely to take a more withdrawn position if there is a standoff over Taiwan than they did in 1996, when the USS Nimitz sailed through the strait.

"The main implication of China deploying this system is that it would certainly make the US navy pause before deciding to project naval power into the South China Sea region during a time of tension," said Felstead.

But China's ambassador to the UK, Liu Xiaoming, said today that his country had no ambitions to rival US military power in the western Pacific region.

"We do not see ourselves as rivals to the US. We believe the US and China can work together in the region," Liu said, arguing there was a double standard in the west towards Chinese defence spending.

"When China carries out an exercise on its own territory there is a lot of attention, but when the United States comes all the way across the Pacific for exercises with its allies, no one speaks about it in the same way. There is a cold war mentality still. If you develop your defence capability, they [the Americans] are annoyed. But our defence construction is purely for self-defence. China's defence expenditure is still the lowest among the five permament members of the [UN] security council."

China's military advances worry many in the east Asian region who have benefited for decades from the US-policed status quo. In its latest defence white paper, Japan noted that China's military spending had nearly quadrupled over the past decade, while its own shrank by 4% due to a stagnant economy.

Officials in Tokyo have also expressed alarm at the increasingly confrontational approach of Chinese vessels in disputed fisheries. In Washington, rightwing thinktanks and commentators want Obama and Gates to apply diplomatic pressure on China to join the intermediate nuclear forces (INF) treaty and halt its missile buildup.

The photographs of the J20 jet are also likely to prompt calls for accelerated production of F35s - the US's next generation stealth fighter - to ensure air superiority.

The US remains the most potent military force in the western Pacific with 60,000 troops, a military airbase in Okinawa and one forward-deployed carrier fleet.

The US also outspends China on defence by a ratio of six to one, according to the Stockholm International Peace Research Institute. Even so, while China's economy grows rapidly and the US remains sluggish, fears of a shift in the balance of power are likely to grow. It will not happen overnight and worldwide, but China appears to be steadily pushing the US back from its shores in a strategy know as "area denial". The government has not confirmed this approach. Chinese nationalists want their country to be more assertive, but they say the priority is to improve defence of an increasingly wealthy coastal region.

The "area denial" strategy can be seen as China trying to manage its own market and routes to main trading partners such as South Korea and Japan.

"We don't need the US to be the policeman in the west Pacific area," said Song Xiaojun, a former naval officer who now edits military magazines.

"China's priority is to develop its near sea defence, because our economy is concentrated on the coast. But we have to reconsider the concept of 'near sea' to fit a modern age in which military threats can come from far away. China must improve its defences, but that does not mean we are a threat. Only arms merchants would say that to persuade the US to raise military spending. The US is far ahead," he said.

China will not strike first with nuclear weapons: FM

China will always honor its promise not to launch a nuclear first-strike, said Foreign Ministry Spokesman Hong Lei in Beijing Thursday.

"The Chinese government made a solemn promise since the very first day it possessed nuclear weapons not to be the first to use them at any time and under any circumstances," Hong said at a regular news briefing.

He made the remarks to refute media reports saying China is mulling a possible change of its non-first-strike policy.

These reports also said that China was considering the merits of a preemptive nuclear strike for self-defense against another nuclear-armed state if no other options were available.

Hong added that the reports were "totally groundless and have ulterior motives."

 

[longbow]

Has always been the case. China has never really advanced it nuclear weapons and have relatively few of them. Just enough as a deterrent. It is US and Russia that have enough warheads to destroy the world over 10 times!

And just look at the number of wars that the US and Russia have been over the last 20 years!
