For the two CEOs are anxious to shut down the 2G network Yang Jie can understand,Telecom and Unicom in the 2G network base station construction is much less than mobile,The vast majority of them are 3G communication base stations using wireless WLAN technology,The impact of shutting down 2G network base stations on these two is not too great,And the number of domestic 2G network users is not too much,The total amount is less than 10 million,Mainly some "old people。

"I think there is no need to be in such a hurry to shut down, in fact, the 2G network occupied by the 2G network occupies some relatively high-quality network frequency bands and is transferred to 4G and the Internet of Things later, and the deep cultivation of spectrum resources is the best choice. ”

Yang Jie said with a smile.

"Internet of Things?"

Huo Zhenrong asked with some confusion.

"Not only our company is researching narrowband Internet of Things technology, but also overseas telecom giants are laying out in this field, and up to now, we have basically realized the data interconnection between people. From the early days of text messages and voice calls, to the current pictures, videos, video calls, and even simultaneous online games, any form of data has become very simple to transfer instantly from person to person. ”

Yang Jie said: "The next step is to connect the equipment and equipment, and strive to achieve the Internet of Everything, our group has also begun to research and develop narrowband Internet of Things technology very early in this regard, and the technology in this regard has begun to mature, and has developed low-cost narrowband Internet of Things chips and modules, which have now begun to be used in the products within our group company, mainly for product tracking, intelligent meter reading and industrial production management." ”

"Now we mainly use this technology within the group company, and we will continue to optimize and improve the product technology, and when the application is mature, we will begin to promote it to various market segments. ”

Yang Jie is not in a hurry to promote this aspect, and will not start to promote it on a large scale until all aspects of narrowband Internet of Things technology are mature.

This set of technology only began to appear in 95 years, Yang Jie from John Bull domestic acquisition of this narrowband Internet of things technology team, this technical team has been researching for three or four years, these years he has been providing research and development funds to this technical team, the domestic technical team began to develop specific application areas on the basis of these technologies.

Huaxing Group has always been the first to use its own product technology, in the process of use constantly find problems and solve problems, they dare to be this guinea pig, through two or three years of use after the product technology is also mature, and then to the market to introduce improved and optimized product technology.

Huaxing Group has now developed the second generation of narrowband Internet of Things technology, and the product technology has been greatly improved compared with the first generation of technology, and it has also established several narrowband Internet of Things networks within the group company.

However, now the narrowband Internet of Things chips and modules established by Huaxing Group itself have reduced the power consumption to a very low level, and the communication distance can also cover a distance of 15 kilometers or even longer, and the communication speed is also very high, but to use the paid frequency band, the system is still very complex, and now the cost of a module has reached 15 US dollars, the cost is still too high, and it can only be used in the company's automobiles, mechanical equipment, aero engines, etc.

Yang Jie knows that the smart home market is the largest Internet of Things application market, but now Huaxing Group wants to integrate the narrowband Internet of Things chip into the embedded processor of these smart homes itself, and there are many technical problems with these manufacturers, and now the cost of these narrowband Internet of Things chips and modules is still too high, at least the price of the chip must be reduced to 2 yuan, and the appearance of the module 3 yuan can be promoted on a large scale.

And smart home actually does not need such a long distance, such a high communication speed, smart home can also choose Bluetooth and WLAN this Internet of Things technology, after all, because Bluetooth uses free spectrum, low power consumption, communication speed can meet home use, the unit price of the module is less than a dollar, the main disadvantage is the short distance.

The WLAN LAN module costs 1 US dollar, uses free channels, has high communication speed, and the distance is longer than Bluetooth, which can reach the order of 100 meters, but there are disadvantages in high power consumption.

The two technologies are inferior to the narrowband Internet of Things technology in remote control, so as long as the cost of chips and modules of the narrowband Internet of Things technology is reduced to a low enough degree, these smart home manufacturers are still willing to purchase, and remotely monitor their own products, can timely understand the status of the product, remind customers to replace the parts of the product, and provide customers with better services.

Yonghan Aviation Technology Co., Ltd.'s products provide such technology, which can understand the status of the engine at any time, and can even predict the life of the product's parts, reminding customers to replace and repair in time, and customers are also very welcome to this business.

This technology is also used in the China Star high-speed train, a large number of sensors are used in the traction system and braking system, and the data of these sensors are connected to the Starlink network through the narrowband Internet of Things on the high-speed train, and the information is transmitted to the control and dispatch center, and these systems can be monitored at any time.

"The number of devices connected to the Internet of Things will definitely far exceed the number of connections between people on the Internet and mobile networks, because all areas will take advantage of IoT technology. ”

Yang Jie said with a smile: "This is a huge market, containing huge commercial value and social value, we have made a rough prediction of the size of this market, the market size of the Internet of Things is very likely to exceed 20 trillion US dollars in 20 years, if the country grasps this industry, it can create trillions of dollars of GDP for our country every year, which is equivalent to the GDP of a medium-sized European country every year." ”

“......”

Zhao Shengji and Huo Zhenrong both opened their mouths wide and were speechless for a while.

"Yang Jie, there is more than one Internet of Things technology, why do you attach so much importance to this narrowband Internet of Things technology?"

Huo Zhenrong asked.

"Indeed, there are now four technical branches on the Internet of Things, narrowband Internet of Things technology, enhanced machine communication technology, low-power wide area network technology, and a sigfox Internet of Things technology, the latter two are their own spectrum resources, and they do not want to share spectrum resources with other countries, so the latter two are destined to be difficult to develop. ”

"Narrowband IoT technology is very similar to enhanced machine communication IoT technology, the latter is stronger than NB-IoT technology in terms of speed, mobility, and voice, but it is much worse than the former in terms of coverage capacity and module cost. ”

Yang Jie said: "In fact, narrowband Internet of things technology can also improve the shortcomings through technical means, these two technologies are not clear, now the industry is also arguing about this, so far there is no consensus, but it has left us enough space for technological development, now our company in this area of technology patents is the most, the main energy is still focused on this in the future." ”
