Rewriting the Technological Scenario

At the end of November, Meng Qian received an invitation letter, went to Yanjing to participate in a meeting, WiMAX has recently been boring for these companies, and China is impossible to react, different companies, different characters, different experts, different experts. Leaders will also have their own ideas.

So, at the end of November, the Ministry of Science and Technology, the Ministry of Information, Ministry of Information, the Development and Reform Commission, and three departments took the lead in opening a meeting, convene five major operators in China and more than ten business representatives and more than ten related experts to discuss discussing WiMAX. thing.

At the meeting site, Meng Qian found that the dispute was very large.

The first is the five major operators, because the needs of the five operators at this time are actually distinct, so the demand for WiMAX technology is different.

From today's statement, Huaxia Telecom, Huaxia Netcom, Huaxia Tietong three companies are supported, especially Huaxia Tung Tong, because Tiemong does not have mobile network business, so Tietong wants to rely on WiMAX in.

The Unicom used the European 3G standard and the mobile movement using the Chinese 3G standard is not too interesting to WiMAX.

Meng Qian listened to it quietly, and all the ideasides of operators were actually from their own profit point.

I know the attitude of the five operators. The leaders began to ask the experts' opinions. Similarly, the difference between the expert group is also large.

A letter is a representative of Ms. Cao Shumin, a big god expert in Huaxia Communications, and they are not optimistic about WiMAX.

Ms. Cao Shumin said, "From the technology itself, WiMAX technology seems to be very mature, but if you want to develop WiMax as 4G, it is not mature, even the basic norms can't do, serious lack of admission Power, billing, operation, etc.

Netcom is done by WiMAX technology test, and it should be clear that the entire WiMAX project is not available. Even a basic solution is not. "

Another party immediately made an objection. "You said that WiMAX is not 4G, and how to explain 3GPP LTE to low mobility broadband access, including similar bandwidth, data rate, and spectral efficiency indicators, low mobility Optimization, etc.

And we can see that the LTE technology route and WiMAX are actually very similar. In terms of wireless interface, it is used to use SC-FDMA. Downlink uses OFDMA, network structure, all of the NodeB is directly accessed into the packet network, simplifies Network hierarchy, etc.

Our Huaxia is now driving TD-CDM-OFDM solutions, but it is difficult to see our program is very difficult to Europe. In this case, why don't we directly choose WiMAX that may be largely commercial next year? "

Cao Limin continued to refute, "Because WiMAX is essentially access technology that can provide ultra-high-speed mobile Internet services, this is impossible to be 4G. What is 4G? If you follow the 3G cognition, then you should be the fourth generation Mobile communication technology. In this case, the revolutionary meaning of 4G should not be reflected in the access layer, and should also be embodied in exchange, control, business, and QoS exceptions.

This is also the biggest difference between 3G relative to 2G. If it is said in a communication technology, only the access level is relatively 3G, I can't accept this a statement such as the next generation of mobile communication technology.

This is the technical white paper of WiMAX, all content is a problem with how to solve the access layer wireless high-speed data access. As for how the data is routed, how to control, WiMAX does not process.

By the way, from our country's development foundation, the international segment assigned to WiMAX internationally is generally allocated in China. . "

Cao Limin's point of view Meng Qian is actually very recognized, but it does not convince the other side, "WiMax is currently based on access, but we have to see the future.

To know that WiMax's development space is very large. First, it has a better broadband mobility in a greater range, which has excellent mobile broadband data service, which will give a better experience for mobile users. Thus, the development and improvement of the network.

And WiMAX can be applied in terms of the last 1 km connection, network backhautment and private network, which can solve low cost broadband access issues in remote areas. Using WiMAX technology to achieve urban wireless access broadband coverage, it can quickly expand user groups, improve information services and applications, which will play a huge impact on our domestic information. "

I can't fight for half a day, everyone is very firm, and the leaders have to come forward to interruption, put their attention to the company, let entrepreneurs talk about their own ideas.

As a result, Hou Weigui relied on the low-key low-key today, and the tacit side looked at Meng Qian.

Meng Qianchi smiled, it is not polite, and turned to see Wang Jianwei, general manager of the mobile group. "Intel has recently been to move."

"I just came before."

"Do he want to make mobile to join the WiMAX camp?"

Wang Jianzhen stunned, I didn't have this thing soon, but they didn't say anyone. In addition to the leadership, no one knows, Wang Jianxu's consciousness follows the leadership to use the eye to exchange I will later asked, "How do you know?"

"I guess." Meng Qian smiled, "Intel said in a press conference yesterday, Huaxia's TD-SCDMA can turn to WiMax, and think that this is a very good development direction, can help us Huaxia quickly breaks through the network construction bottleneck. Lenovo has been to the mobile phone a few days ago, I probably guess what they came to live. "

Wang Jianzhen said very confident, "But we will not give up our own standards."

"Of course we can't give up our own standards, otherwise we have been fighting for the old life, 4G, must not be wronged." Meng Qian said such a sentence, "everyone is also clear, let's develop these two years, everyone The future 4G looks actually has gradually had a more mature concept relative to the past, that is, OFDMA can also solve the same frequency multiplex, everyone is more inclined to use OFDMA as a 4G basis, and its purpose is to avoid high-turn tax.

After all, even the rice companies can't wait to kill Qualcomm, coupled with our wind groups to 4G research and development, we basically determine that the future 4G is largely, it will not be 3G extensions, more likely to be a different New communication technology in 3G foundation.

And from the current development of LET, the main technological of the future 4G has begun to have more and more consensus, but there is a technology. We can't agree with Omi, that is, TDD and FDD, that is, time duplex is still Frequency division duplex.

Perhaps because our performance in 3G is really unlikely, FDD is now significantly more attention, but if we want to have our own 4G standard, if we hope that our 4G is no longer like 3G If we have to find ways to drive the coverage of TDD technology.

So if you want to ask me not to support WiMax, my idea is that Intel said that TD-SCDMA can turn to WiMAX, then I put this order, is it?

WiMAX seems to be turned to TD-SCDMA, and WiMAX can seem to have this road if you want to turn. "

After the failure of WiMAX in that year, the qi and unfamiliar bonused, the WiMAX was found to be turned around, and the best transfer direction of WiMax is the TD-LET in China.

As a result, Huaxia has put his 4G market share, which may also have a certain luck ingredient by WiMAX failure.

But at this time, everyone is still very difficult to accept this statement, and several experts have a few experts to say, and they are say, they are swallowed. From now on the eyes, everyone feels that Meng Qian said It's too crazy, this is to make a wedding dress for China in China. When I was just ready to engage in WiMAX, Meng Qian actually said this, what is it?

In the end, some experts couldn't help but Meng Qian, said that he is in the world.

Meng Qian didn't care, "Of course, I am just a possibility for everyone to learn."

After saying, Meng Qian looked at the leadership, but the leaders looked at Meng Qian's expression, but the heart did not consciously appeared some strange ideas.

Experts in the scene have nothing to translate with Meng Qian, but several leaders who come today with Meng Qian have already exchanged several times.

Although this is very mad, people who say this are Meng Qian ...
