In the fierce military competition between China and the United States, not only have both China and the United States greatly increased their budgets in military input, but all kinds of new weapons have begun to emerge one after another, making this stage another golden age in the history of the development of the world's military industry. Although all this has put the whole world in a more dangerous state until a new balance is reached, new weapons are always accompanied by new technological inventions and creations, and they are also greatly promoted in civilian products.

Duke, as the butterfly that triggered this huge military race, has profoundly changed the world.

Stepping into the new year, SAL's heavyweight product, a new generation of wireless communication products, was successfully developed.

On January 8, 2021, the large demonstration hall of more than 2,000 square meters of SAL headquarters was crowded, and all the bigwigs in the domestic communications industry, including the Minister of Information Industry, the chairman of the three major operators and the CEO of a major communication equipment manufacturer, were all present, because today SAL is going to hold a new generation of wireless communication product launch conference.

"Hello everyone, welcome to SAL's S-WiNet Super Wireless Communication Product Launch, and you will see a revolutionary new wireless technology!" The spotlight shined on Cai Siqiang's whole body a little hot, but he didn't feel it at all, because he was very excited today.

"SAL's S-WiNet solution, approved by the Ministry of Information Industry, has started an experimental network in Chengdu, and today it will start its first public trial operation in the presence of all guests!" Cai Siqiang went straight to the topic after a simple opening remark, pressed the button in his hand, and opened the large magic mirror curtain wall in the demo hall.

A huge 68-meter-high base station breaks through the clouds, in an extremely realistic 3D animation, full of a groundbreaking spirit, "This is the S-WiNet base station standing on Longquan Mountain, and today our entire trial operation will be through it to complete the audio and video communication demonstration in several different cities." ”

As soon as Cai Siqiang's voice fell, it immediately caused an uproar among the guests present, a base station covers several cities, this is an unheard of new thing, which one is SAL singing today? For the industry peers present, they were told that SAL would have an important industrial cooperation plan announced today, so they all gathered in Chengdu, but they did not expect SAL to let everyone watch the release of SAL's new generation of wireless communication products before talking about cooperation.

Cai Siqiang didn't pay attention to everyone's commotion, but raised a new mobile phone in his hand and dialed a number, Cai Siqiang quickly switched the screen on the mobile phone wirelessly to the magic mirror curtain wall, "Hello, Mr. Cai!" I'm Jiang Xiaoming, a test engineer, and I'm talking to you in the Sweet City Building" As the voice came out clearly, a real-time video image of a person appeared after the screen shook a few times, and a young and somewhat nervous face appeared in front of everyone.

"Jiang Xiaoming, now please point the camera at the Tiancheng Building" Cai Siqiang said to the young engineer with a smile, after a few slight shakes, the guests present saw the whole picture of the building more than 100 kilometers away, the bustling crowd around the building and the magic mirror curtain wall of the building that was playing the news, all of which showed that it was now completely implementing a full video call.

If you see this, everyone is still a little skeptical, but then each heavyweight guest received an S-WiNet terminal, which can be dialed at will more than 20 built-in numbers, and have live video calls with SAL test engineers near more than 20 famous buildings in different cities around Rongcheng, and at the same time, they can also watch the nearby news broadcast on the big screen, and find passers-by at any time to look at their watches, etc., indicating that SAL does use a new wireless communication technology.

This unique product launch was an instant sensational success. In your tests, the maximum distance that can stably use HD video calls has exceeded 150 kilometers! This means that this new type of wireless communication can also support a transmission speed of 100Mbps at this distance, which is comparable to the transmission rate of 4G networks, but the transmission distance is more than ten times exceeded.

More than ten minutes later, Cai Siqiang interrupted the test work of these almost crazy guests and gave a brief overview of the performance indicators of the new generation of wireless communication:

A single base station can support up to 50,000 voice users, and concurrent data users can also reach 5,000.

Voice users cover a distance of more than 200 kilometers; For high-speed data transmission, the maximum transmission speed is 100Mbps within 150 kilometers, and the maximum transmission speed is 1000Mbps within 100 kilometers.

Support 1000M interconnection between base stations and base stations, that is to say, for remote areas, low-cost coverage can be considered through base station interconnection.

This kind of super wireless communication technology born from Duke's invention and first applied in the military, purely from the point of view of indicators, has fully possessed the function of replacing the existing mobile communication network and home broadband access network, but from the perspective of networking, it is much simpler than the current network, if you want to support large-capacity concurrent data users, you need to connect large-capacity optical fiber to the base station to ensure the demand for big data transmission; However, if it only supports general audio and video communication requirements in remote areas, it only needs to be connected wirelessly between the base station and the base station to quickly establish a communication network.

Moreover, the ultra-long coverage distance and large-capacity user support greatly reduce the number of base stations that need to be built in the entire network, and compared with the original 4G network, the number of base stations required is reduced by at least several times or even ten times, which greatly reduces the complexity of construction, the difficulty of network deployment and the cost of later maintenance.

For the industry bigwigs present, this is the only choice to replace the 4G network, so, after the presentation, everyone suddenly remembered that SAL said an important industrial cooperation plan when invited, and then realized that SAL is planning to be ambitious, and they are ready to promote a new industrial upgrading, such a huge market prospect SAL can not be eaten, so the industry bigwigs present are aware of a huge business opportunity in front of them.

Sure enough, at the industry cooperation meeting held after the demonstration, Cai Siqiang released a fairly extensive industrial cooperation plan on behalf of SAL, ready to work with the domestic communications industry to develop this new wireless communication technology into a new generation of communication standards, and SAL has prepared a package of solutions from core chips to operator services.

In order to promote the development of this new industry faster, Cai Siqiang promised that for domestic manufacturers, the terminal products will be charged patent fees at one percent of the selling price, and the system products will be charged at five percent of the selling price.

That is, since 2G/3G/4G, the domestic manufacturers who have been exploited by most of the core patents of wireless communications in Europe and the United States have finally ceased to be controlled by them, and SAL has signed a package of licensing agreements to solve the biggest problem that plagues everyone's development.

However, Cai Siqiang is not disappointed because of the low-cost patent authorization, in this nascent market, he is not ready to make profits through patent licensing, but to start the market with patent concessions, because to build a large network covering the whole country, the total investment in system equipment is almost close to 700 billion, and after the network is completed, the annual consumption on the terminal is conservatively estimated to be more than 200 billion, that is to say, once the market is launched, at least a new market of more than 300 billion will be formed every year. This new market is what Cai Siqiang values.

With SAL's superior product quality and market image, they will undoubtedly occupy most of the mid-to-high-end product market, and the core chips are now provided by Duche Electronics, a subsidiary of SAL, SAL can maintain a leading position in this industry chain for at least more than ten years. That's why SAL launched this high-profile industrial cooperation plan and the original intention of patent licensing.

However, other manufacturers have nothing to complain about, because SAL company will put a new industrial opportunity in front of everyone indiscriminately, if 2G/3G or even 4G everyone is struggling under the patents of European and American manufacturers, now we have a better starting opportunity than European and American manufacturers, one step ahead in the domestic promotion stage, and will get a better position in the future international promotion.

With such excellent product performance, everyone is confident that this will be the international standard for a new generation of wireless communication technology, and it is only a matter of time before it is different.

As for China, Xu Zhe, Minister of Information Industry, highly praised SAL's technical contributions at the industrial cooperation conference, and also expressed his appreciation for SAL's patent licensing plan, hoping that domestic manufacturers can join hands to build this new industry, not only for the upgrading of the communications industry, but also for the domestic economy to create a new growth point. Obviously, the government is happy to see the industrialization of this technology.

If there is one lost person among the industry bigwigs here, it is the chairman of China Mobile, who has just spent hundreds of billions of dollars to complete the construction of the entire 4G network, but after SAL released this new technology, if a new network is built, it will suddenly make their efforts to regain their dominant position in vain.

But now various domestic manufacturers have accepted SAL's technology almost all at once, in addition to them, China Unicom and China Telecom, two operators that are slow to move in 4G, are also very interested in SAL's new wireless technology and have publicly expressed their support.

It's just that in the end, it will be a battle between them who will win this new wireless communication technology, but whoever gets to use these new technologies to build the S-WiNet network of the future will gain a new competitive advantage in the domestic market.

Therefore, in a new wireless century, some people are happy and some are worried.
