Tu Su: "..."

Professor Chen: "..."

Looking at the video on the big screen, which only had a download speed of more than [-] megabyte, the entire classroom suddenly became strangely quiet.

Su Yun spread his hands helplessly, and said: "In fact, I found that the speed of this thing is almost the same as 4G, and the download speed is only a few megabytes per second. On the way back, I couldn't help but fell into a dilemma about life and society. Think big."

"So I immediately contacted the information technology staff at the Academy of Sciences at the time. Coincidentally, that week, the information technology staff happened to be in Beijing, and even more coincidentally, the confidence technology staff The staff member is in our villa area on Sanshun Road, so I stopped by to find this staff member."

"After I inquired about it, the staff told me that I couldn't connect to 5G because China Unicom was still testing in this villa area and it hadn't been opened to users yet. The speed I actually experienced was still 4G speed. .”

Su Yun shook his head and sighed: "Hearing this, my heart is half cold, but the most coincidental thing has come. The test is expected to end on Friday of that week. If it goes well, it will be open on the weekend."

"So two days later, I drove to the villa area on Sanshun Road again, and this time."

Su Yun just left a mysterious smile, and once again called up a video from his mobile phone to the computer, and then lightly clicked the mouse on the computer, everyone who opened the video was stunned.

In the video, there is a software for testing the network on Su Yun's mobile phone, which is directly full from left to right!The highest speed even directly reached 1000Mbps! !
Then there is the speed of downloading the software. It seems that it is almost ten times faster. It is not too late to see what is downloaded, and the download has already been completed!

A total of 215 softwares were downloaded, and it only took less than 1 minute!

Even Professor Chen who was sitting at the back was dumbfounded.

Everyone knows that the speed of 5G will be very fast, which will be many times that of 4G, but not many people have really seen the speed of 5G.

So when they saw this terrifying download speed, everyone was stunned, leaving only a 'shit' expression on their faces.

Su Yun continued: "This thing is really fast. The average download speed is around 700Mbps, and the upload speed is around 80Mbps, which is almost ten times the speed of 4G!"

"At the beginning, I wanted to download a program to check the download speed, but when I downloaded some daily life applications, it was too late for the page with the speed, and the download was over."

"Only when downloading some larger applications, I found that the download speed remained at about 60M/s, and the experience of downloading songs with 5G is better. For a 10M song, the progress bar only has two states: full empty and full, which is simply impossible. Didn't stay in the middle."

"Watching the video with the highest bit rate on various platforms, you can also drag the progress bar at will, which is almost the same as watching it after the cache is finished. The delay of playing games is also stable below 60ms."

Watching Su Yun explaining, coupled with the real download speed on the big screen, everyone listened with gusto. What's more, they took out their notebooks and started to take notes.

Su Yun walked around on the podium with small steps, and continued: "After experiencing 5G all day, I have two biggest feelings. The first is that this thing is really cool to use. Greatly optimize the current network experience."

"The second is that cloud storage is definitely a trend. When this thing is the fastest, the download speed is 90M/s, which has almost caught up with the reading speed of the SD card in the mobile phone. With such a fast network speed, you can save photos and There is almost no difference whether the video is saved locally for viewing, or uploaded to the cloud, and downloaded for viewing when needed!”

Having said that, Su Yun paused for a moment before continuing:
"Finally, after a day of smirking at the test software, the sky gradually darkened, and my excitement about this speed gradually became dull. On the way back, I still fell into big thinking about life and society."

"Think about what we need to do on our mobile phones that require the network? It's nothing more than watching videos and playing games, but these needs are also met under 4G. Of course, the experience with 5G will be better, but there are always some killers. It feels like a chicken with a sledgehammer. There are certainly not a few people who have this kind of thinking."

"In fact, from the first day I got this phone, I searched the Internet every day for what is the use of 5G? Answers always predict VR, AR, autonomous driving for all, and the Internet of Everything."

Su Yun shook his head with a smile, glanced at the audience, and said: "But these always sound too far away and too complicated to implement, so after that, I changed the search method, and I searched for 'what is 4G? Use?', but I set the time in 2018-2019, which is the time when 4G will be commercially available."

"Standing in the future, it is really interesting to see the predictions of the predecessors for the present."

Everyone was slightly taken aback, even Tu Su listened with interest and earnestly.

Su Yun continued: "At that time, most people were complaining that 4G was useless and the tariff was so expensive, but five years later, most people no longer have the awareness of saving data."

"As for the predictions of 4G applications back then, we could indeed see some clues of the future, but they were a little too unimaginative. For example, everyone knew that 4G could watch high-definition videos, but at that time everyone was talking about how convenient it is to watch movies on mobile phones. No one The complete explosion of short videos is predicted."

"For example, we all know that 4G is conducive to the popularization of mobile payment, but the ideal way at that time was to tie a credit card to the mobile phone and then add NFC. No one thought that such a simple and crude method of adding a QR code to the network would really kill cash. "

"For example, we all know that the upload speed of 4G can be used for live video broadcasting, but the idea at that time was to apply it to the professional news field. I didn't expect the era of live broadcasting for all people. Not to mention that there are various e-commerce, food delivery, and taxi-hailing platforms. rise."

"In just five years, 4G and the services it spawned have profoundly changed the lives of each of us, but you may just feel... oh, the Internet speed is a little faster, right?"

Everyone listened quietly, no one made a sound.

They have already predicted that it won't be long before Su Yun's speech will definitely set off a wave of enthusiasm!
"People's predictions about the future cannot escape the limitations of current technology and thinking." Su Yun stepped down from the podium and said, "The most typical example is that if you ask a person 50 years ago, what is the future? What does it look like? He might tell you that the car will run in the sky."

"50 years have passed, and cars have not gone to the sky, but the birth of computers and information technology will definitely change society no less than flying cars."

"It's true for 50 years, maybe it's true for five years."
