Everybody in China knows that data transfer rates here, even between domestic servers and clients, are appalling. At present, China ranks 71st in the world for broadband connection bandwidth, with the average connection offering only one-fifth of the average bandwidth of connections in the US (generally between 20 and 25 Mbps). With typical home connections being between 1 and 2 Mbps, using the internet in China often feels like going back ten years from what customers in Japan, the US, and the EU are generally used to.

Not only is the internet slow, however- it’s also expensive. A study released by the Hangzhou Metropolitan Express on December 23rd revealed that fifty percent of China’s 150 million broadband users are currently paying more than their counterparts in other countries for broadband service. 1Mbps of bandwidth in China runs an average cost of US$13.13- three times higher than Vietnam, four times higher than the US, 29 times higher than South Korea and a mind-blowing 469 times higher than Hong Kong!

Fortunately, there are signs that relief is on the way. Miao Yu, head of the Chinese Ministry of Industry and Information Technology, has announced that the ministry intends to bring average broadband bandwidth in China’s urban areas to 20 Mbps by 2015, with a serious push to lower access costs and increase average bandwidth before the end of 2012.

“China’s broadband bandwidth is relatively behind the level of many countries, and with an unreasonably high price. We aim to invest heavily to improve it by 2015,” he said on December 26th.

But questions remain as to why China remains so far behind in the bandwidth race to begin with (especially when other Asian high-tech powerhouses- especially the Hong Kong SAR- are so far ahead). One obvious candidate that has been put forward is the state-owned China Telecom/China Unicom duopoly, which some, including the state’s National Development and Reform Commission (NDRC), believe have been preventing potential competitors from entering the market and potentially providing superior (or at least competitive) services. While the NDRC has launched an investigation to see if this is a cause, it seems unlikely that the state-sanctioned duo will let go of their death grip on the country’s high-speed internet access any time soon.

China’s first integrated wind-solar power demonstration project has been completed and put into operation on December 25 in Zhangbei county of north China’s Hebei province, according to a source at North China Grid Co., Ltd, constructor of the project.

The project is the largest new energy project in the world that integrates wind power generation, solar PV power generation, power storage and intelligent power transmission,
said Zhao Yuzhu, deputy general manager of North China Grid.

With an initial investment of 3.3 billion yuan, the project is currently equipped with installed capacity of 100-megawatt (MW) wind power, 40-MW solar PV power and a storage capacity of 20 MW.

The power plant realizes complementary use of solar power and wind power by generating electricity through solar PV power during the daytime and electricity through wind power at night, which has enhanced the utilization rate of wind turbines by 5-10 percent, noted Zhao Yuzhu,

Meanwhile, with the power storage and intelligent power transmission, the project is to break down the bottleneck of the China’s new energy development in areas of grid connection, according to Zhao.

Solar power has already become an essential part of China’s strategy for sustainable development, and is also key to Zhangbei county’s plans to develop its economy. The sunshine in Zhangbei is abundant and its duration is quite long. The total sum of radiation measured there can peak at 5860 mega joules per year, while 2994.7 hours’ radiation can be used, making Zhangbei an ideal place to develop the solar power plant. To speed up the development of solar energy resources, the county continues to consolidate its position as the leading industry of wind power bases and diversify its way of developing into a more comprehensive strategy, relying on multiple energy sources to continue to strengthen the development of solar and wind power and attract investment.

For this project, BYD, a large Chinese manufacturer of automobiles and rechargeable batteries, has teamed up with the State Grid Corporation of China (SGCC) and constructed what they think is the world’s largest battery energy storage station.

“This large utility-scale project, located in Zhangbei, Hebei Province, combines 140 Mega-Watts of renewable energy generation (both wind & solar), 36 Mega-Watt-Hours (MWh) of energy storage and a smart power transmission system,” the news release notes.

“BYD’s battery energy storage system provides a solution for the realization of energy storage in the smart grid that improves renewable energy efficiency by 5%-10%.”

BYD provided “energy storage batteries in arrays larger than a football field” for the project and state that the entire project is worth over $500 million USD.

“This State Grid project demonstrates a solution and will be the model of development for China’s new energy resources,” Xiu Binglin, Deputy Director of the National Energy Administration, said.

China's 6MW offshore wind turbines.

"Shanghai offshore project first to order Sinovel 6MW turbine

China’s Sinovel has won a tender to supply 17 of its 6MW wind turbines to an offshore demonstration project in Shanghai port.

The wind farm, to be developed by Huaneng Renewables, is Sinovel’s debut commercial order for the 6MW model and will be the first in Asia to use such large turbines.

The move represents a milestone for China’s wind power industry, says Celia Sun, managing advisor at Make Consulting in China.

Chinese turbine manufacturers are working to rapidly scale-up their turbines for offshore wind farms, an area seen as less competitive than the saturated onshore market and with good growth prospects.

Sinovel was the first to complete a 6MW prototype, installing it off the coast of Jiangsu province last year. The company’s 3MW turbines have been in operation at the 100MW Shanghai Donghai Bridge wind farm since 2010.

“Sinovel has always been at the forefront of China’s offshore wind power development," says senior vice president Tao Gang.

The new offshore project comes at a crucial time for Sinovel, China’s top turbine maker. Preliminary data for 2011 wind farm installations shows that the firm is losing market share to fast-growing United Power and Ming Yang.

“With the Chinese industry entering a period of consolidation, the company is under pressure to defend its leading position. This is a sign that it is still out in front,” says Sun.

The Beijing-based turbine manufacturer has also made clear its ambitions to dominate the global market and has put significant emphasis on developing larger turbines to catch up with industry leaders.

These include Suzlon-owned REpower which has already installed 6MW turbines onshore and is currently building the Nordsee Ost offshore wind farm for RWE with its 6MW machine. Siemens also has an onshore 6MW prototype in operation and has agreements to install the model in trial projects this year. ......................................................................"

Top gear: China's Huawei outmuscles Swedish rival
Please, Log in or Register to view URLs content!


When Huawei Technologies posts its annual results in April, they will likely show the unlisted Chinese firm has overtaken Sweden's Ericsson as the world's top-selling telecoms equipment maker.


As with solar panel maker Suntech Power, another Chinese manufacturer that is a world beater yet little known beyond the Great Wall, it's been a rapid rise to the summit.

And, as the pace of global spending on telecoms equipment slows -- on the switches, hubs and base stations that connect networks -- Huawei has been building serious growth in new areas such as smartphones and its MediaPad tablet PC.

Globally, Huawei already ranks sixth in mobile phone sales.

Privately-owned Huawei was founded in the southern boomtown of Shenzhen by CEO Ren Zhengfei just 25 years ago, after he left the People's Liberation Army as part of a scaling down of the world's largest military force.

Now 68, Ren, who was named the fifth most powerful Asian executive by Fortune in 2011, was involved in military technology development for the PLA before setting up Huawei with just 20,000 yuan ($3,200).

Annual sales are forecast at around 200 billion yuan ($31.7 billion), around two-thirds of which, some $21 billion, are from telecoms gear, putting it ahead of Ericsson's 2011 network sales of $19.8 billion. Ericsson, which has a market value of more than $31 billion, has led the mobile telecom equipment market for at least the past decade.

GEAR GROWTH SLOWS

Global spending on telecoms equipment is forecast to grow 6.9 percent this year to $444 billion, slower than last year's 7.7 percent growth, dented by Europe's debt crisis and the generally weak economy that has checked spending in the IT sector, according to IT research firm Gartner.

Ovum, a UK research firm, sees a similar trend, with growth in telecom operators' spending slowing to 5.5 percent in 2012 from 12.2 percent last year.

About two thirds of Huawei's revenues come from selling telecoms gear -- where it also competes against Nokia Siemens Networks GmbH, Alcatel Lucent and ZTE, another Chinese firm.

As well as consumer gadgets, Huawei has pushed aggressively into selling routers and switches to corporations in the so-called enterprise sector, a growing $35 billion market dominated by Cisco Systems and Hewlett-Packard.

"There's a lot of price pressure now (from the Chinese firms) and this is going be tough for Ericsson," said Bill Rojas, an analyst at research firm IDC.

Some analysts, however, say Huawei needs to build strong channel partners -- distributors and systems integrators -- over the next 3-5 years if it's to compete in the enterprise sector.

"The market is wide open, this is anybody's game," said Matt Walker, an analyst at Ovum, referring to the telecoms market. "I know some observers will see a conservative growth outlook, think it means a tight price climate, and conclude that this favors Chinese vendors. I don't see this."

"Huawei and ZTE are positioned well in both these markets, but so are others," he said. "Services may be a big part of it."

Ren's background with the Chinese military has often been cited as hindering Huawei's progress in telecoms technology in North America, though the company has repeatedly denied having links with the armed forces.

Last year, Huawei backed away from buying U.S. server technology company 3Leaf's assets, bowing to pressure from a U.S. government panel, and in 2008, it gave up on a bid for U.S. networking equipment company 3Com. In 2010, some Republican lawmakers raised national security concerns about Huawei's bid to supply mobile telecoms equipment to Sprint Nextel Corp.

GEAR TO GADGETS

The real future growth driver for Huawei, and ZTE, also based in Shenzhen, is likely to be in red-hot consumer gadget markets, helping take up some of the slack in telecoms.

Huawei's consumer devices -- dongles, mobile phones and tablets -- now bring in almost a fifth of its revenues and these sales are powering ahead at 40 percent, the company said last month, twice the growth seen in 2010.Huawei had sales of $6.8 billion in its consumer business last year, and is moving up the value chain by selling more of its feature-filled IDEOS and Vision smartphones.

A key advantage here is price.

Huawei's new Ascend smartphone sells at around $400, much cheaper than the most basic Apple iPhone 4S, which costs around $650 in Hong Kong stores. The phones are increasingly available at stores in glitzy Chinese malls and have featured at a Milan fashion show.

"Chinese users prefer mid-range smartphones as they are more affordable than the expensive high-end ones, and have a much better user experience than low-end phones," microblogger Hu Yang wrote on Sina Weibo.

"Let's hope Huawei introduces more such mid-range smartphones in the future, (though) I hope Huawei improves its software capabilities in smartphones as mine still has some bugs that aren't resolved."

As sales grow rapidly, Huawei hopes margins won't be compromised.

Its overall gross profit margin rose to 41.9 percent in 2010, from 39.6 percent, while, at Ericsson, gross profit margin declined to 35.1 percent last year from 38.2 percent in 2010.

"We are trying to have a strategy that doesn't revolve around price," said a Huawei executive, who declined to be identified as he was not authorized to speak to the media.

"Over the last 2-3 years, we have been focusing more on value, like customization, support and systems integration."

Other new growth areas Huawei is looking at include fourth generation (4G) Long Term Evolution (LTE), an upgrade from 3G technology that promises faster data downloads."Huawei is very competitive in LTE products. They're going to take away more market share," said IDC's Rojas.Huawei has clinched more than three dozen fourth generation LTE contracts globally with major operators such as Japan's Softbank Corp, and sees sales of LTE equipment doubling next year, a senior executive said in November.

The Chinese firm, which employs more than 110,000 staff worldwide, has been offering solutions to operators that will help ease network migration with its singleRAN (radio access network) technology.

As part of a branding and image drive, Huawei also bid, unsuccessfully, to set up a phone network in London's Underground during this year's Olympic Games.

Huawei's Asian base, particularly in its home market, may also prove beneficial, both for its telecoms gear business and device sales.

"The good thing is that Asia still needs to catch up with network deployment. The demand is there," said another Huawei executive, who also asked not to be named.

"It may not be the same growth rate as before, but it's still quite significant compared to other parts of the world."

What makes this even more impressive is this is achieved despite having virtually the entire US market denied to them through protectionist measures and phoney security concerns.

Chinese development of domestic microprocessors for high performance computing seems to be ramping up. The Godson-3B and ShenWei SW1600 CPUs were the first out of the gate, with the latter chip powering a Chinese petascale supercomputer. Waiting in the wings is the FeiTeng processor, an architecture that could be the one that takes Chinese supercomputing into the exascale realm.

Although, there is not a lot of information publicly available on the latest FeiTeng chip, at one time it was being promoted as "the world's first 64-bit stream processor dedicated for high-performance science computing."
The architecture, which is variously known as the FeiTeng, YinHe, the YinHe FeiTeng, and the FT64, has been developed at the National University of Defense Technology (NUDT) in Hunan Province. The design work culminated in its first implementation under the FT64 moniker in 2007.

According to a paper presented at the International Symposium on Computer Architecture in 2007 (ISCA 2007) and published by the ACM that year, the FT64 architecture and instruction set was specifically designed with high performance computing in mind. The instructions are of the VLIW persuasion and nearly half of them apply to 64-bit FP operations. Not surprisingly, about 36 percent of the die is devoted to arithmetic operations.

This first-generation FeiTeng was implemented on 130nm process technology and, at 500 MHz, delivered a peak performance of 16 gigaflops. While that's nothing to get too excited about today, keep in mind that the FT64 is nearly five years old. What's more impressive is that the chip consumed a mere 8.6 watts of power, which would yield an energy efficiency of about 1.8 gigaflops/watt.
The current top of the line NVIDIA GPU in the Tesla M02090, built on 2011-era 40nm technology, delivers about 2.9 gigaflops/watt.

Like its GPGPU cousin, the FT64 was meant to run as a coprocessor, driven by a host CPU. The ACM paper describes an HPC system board that had one host driving eight FT64 and communicating with each coprocessor via an on-chip host interface. Like the GPU-CPU systems of today, FT64 memory and host memory are separate.

The FT64 designers also came up with a stream programming language called SF95, which extended FORTRAN95 with 10 compiler directives to exploit the architecture. The compiler was used to benchmark the FT64 against an Itanium 2 using nine science application kernels (FFT, EP, MG, Swim, CG, Laplace, Jacobi, GEMM, and NLAG-5). Except for the CG kernel where the FT64 had just a tenth of the Itanium's performance, the stream processor was between 1 and 2.5 times faster than the Itanium on the other kernels, and 8 time faster on FFT.

However, a somewhat different picture of the architecture emerged, based on a seminar delivered last month (December 2011) at the National University of Defense Technology. The seminar abstract is provided here:

YinHe FeiTeng (YHFT) series high-performance general-purpose CPUs, aimed for high-performance computing, are developed by school of computer, National University of Defense Technology
. The first generation of the YHFT CPU adapts the EPIC (Explicitly Parallel Instruction Computing) architecture. Its ISA (Instruction Set Architecture) is fully compatible with Intel Itanium2. The second generation is based on the SoC (System-on-Chip) architecture. It is composed of a general-purpose CPU and a stream processor, which is the world's first 64-bit stream processor dedicated for high-performance science computing. The processor has been successfully used in the YinHe high-performance supercomputer system as an accelerator. The research results are published at ISCA 2007 and IEEE TPDS. The third generation of the YHFT CPU is a multi-core processor. Its ISA is fully compatible with SPARC. It supports floating-point SIMD (Single Instruction Multiple Data) and multi-chip interconnection to enhance parallel processing and constitute a SMP (Symmetric Multi-Processing) system directly. The first version of this multi-core processor has been used on the TH-1A PFLOPS supercomputer systems, and the ongoing upgraded version will be taped out in the next year and used in the next generation of the TH supercomputer system.
According to this, the FT64 was actually the second generation of the architecture and was deployed in some fashion in one of the YinHe (Galaxy) supercomputers in China -- presumably this one, although theoretically there could be an even lower-profile YinHe machine in existence somewhere else.

The third generation of the FeiTeng architecture sounds more like a conventional, standalone CPU, rather than a stream accelerator per se. The reference to this latest chip being used in the TianHe-1A supercomputer, with upgraded version due to be deployed in the next generation TH machine, is especially interesting. At 4.7 peak petaflops, the NUDT's TianHe-1A is currently China's most powerful machine, but is powered by Intel Xeon and NVIDIA Tesla parts.

It's not clear how big a role the upgraded FeiTeng chips will play in the next generation TH machine, but the NUDT has not been any more loyal to chip manufacturers, than its US counterparts. In 2010, the NUDT used Intel Xeon and AMD's Radeon GPUs for its first generation petascale machine, the TianHe-1. The following year they switched to NVIDIA GPUs for the TianHe-1A.

Given China's desire to develop and use indigenous microprocessors for its HPC sector, it wouldn't be too surprising to see FeiTeng processors replace both Intel and NVIDIA parts in a future NUDT supercomputer. Obviously, supercomputing centers in the country are experimenting a lot with microprocessors, although at this point are willing to use just about anything that maximizes performance. But it's almost certain that China would want its first exaflop machine to be entirely built with domestic technology, including, of course, the microprocessors.

There is no need to build a stair when there is already one available. The limitations of traditional Photolithography and steppers have already been identified, all that's left to do is to perfect the current process to reach the maximum potential. The west has already established a system to gradually increase the completion rate of the procedures, there is no need to waste resources doing the same thing.

Perhaps not and they may not need to enter the US market :) ... remember it also works both ways, I highly doubt it that any US telecommunication company would enter Chinese market :)

I am sure the US has been doing it for sometime to implant something to foreign communication eqps and satellites made by the US. And it backfires them and thought other (read China) would do the same to the US. The analogy is like a thief would be suspicious for any policeman nearby him/her
