What are the advantages of 5g combined with the Internet? Wu Hequan, academician of the Chinese Acad

Today, the '2019 Sohu technology AI Summit' hosted by Sohu technology was held in Beijing. Wu Hequan, academician of the Chinese Academy of engineering and chairman of the future mobile communication forum, said at the meeting that at present, the development of the Internet is in a continuous period between the old and the new. 5g appears at this time. When the consumer Internet needs to be deepened and the industrial Internet needs to start, 5g comes just in time.

Wu Hequan pointed out that 5g's own capabilities have come successively with artificial intelligence, big data, cloud computing and blockchain technology. 5g will play a greater role because of them, and the new generation of technology will be strengthened by 5g.

Wu Hequan said that everyone in mobile communication has gone through the first generation. Cellular cells distinguish users by different frequencies, which is analog. SMA represents 2G, which is digital and time sequential. 3G distinguishes users by different code channels. 4G makes use of the spatial factors of frequency. The peak speed of 4G is 100 megabytes. 5g is a little more advanced than the previous 4G, but not much changed.

"But it's different in more important applications," Wu said. If 4G is consumer oriented, 5g is industry oriented. We say that each generation of mobile communication is 1000 times the peak speed of the previous generation. 5g will reach 20g when it works in the millimeter wave band in the future.

So, what are the benefits of 5g combining with the Internet? Wu Hequan gave the answer. In his opinion, the internet usually perceives data, but only perception is useless, and data analysis needs to be used for artificial intelligence. Big data artificial intelligence is often in the background. There needs to be something between the foreground and background. For some fixed Internet terminals, optical fiber can be pulled, but it is difficult to pull in the field. Most want to use wireless technology. Before 5g, wireless technology can't provide enough bandwidth, connection number and low delay. It's impossible to turn into Internet and artificial intelligence in real time, so artificial intelligence decision-making can't produce real-time efficiency. Now 5g appears, which makes the two seamlessly integrated. AI + IOT becomes aiot, which becomes the intelligent Internet of things. When we almost integrate the cloud capabilities into the terminal, virtualization sinks to the terminal, and the terminal capabilities are greatly enhanced. Aiot uses many technologies to support it, including AI chip development tools and software. With these, 5g can play a greater role.

Through the innovation of wireless network technology, 5g can enhance the ability of high reliability, low delay, wide coverage and large connection of mobile broadband, drive the seamless integration of artificial intelligence and Internet, expand and strengthen the application effect of artificial intelligence. Wu Hequan said that in the future, AI + IOT will be 5g to aiot, AI + it + ot will also be aiot, 5g will play a greater role in industrial production and life.
