Meanwhile.

The tests do not stop at home, and tests are being carried out in secret in various insensitive regions around the world.

On Pridz Bay in Antarctica, August is a sunny summer in the Northern Hemisphere, while Antarctica in the Southern Hemisphere is a snowy winter.

The icebreaker tore through the ice on the sea and approached Nakayama Station.

Because the ice was so heavy, the icebreaker could only advance to about five kilometers from Zhongshan Station, where it docked and unloaded a large number of supplies.

The expedition team from Zhongshan Station was already waiting for them nearby, and then used a sled cart to pull the supplies back to Zhongshan Station.

In the midst of the blizzard, the convoy withstood the fierce and biting strong winds, leaving scratches on the ice, and only a white expanse remained between the sky and the earth at this time.

The members of the scientific expedition team wore thick down jackets and sunglasses to prevent snow blindness, and the snowstorm became heavier and stronger, and the sky began to darken, and aurora lights appeared in mid-air.

The polar night of Antarctica is shrouding this continent, but the latitude of Zhongshan Station is near 69 degrees south latitude, which is not the highest latitude scientific research station. Scott Station.

Seeing the hazy lights of Zhongshan Station, a group of members of the scientific expedition team breathed a sigh of relief, Antarctica in winter is not only a snowstorm and a polar night, but also a terrifying low temperature environment.

"Whew!" With a white breath, the stationmaster looked at the supplies in the warehouse, and then he breathed a sigh of relief, he picked up the supply list and counted these things.

Suddenly, he found that there were some electronic devices on the list.

[30 mobile phones, 15 notebooks, 6 micro base stations.] ］

"Huh? What are you doing with your phone and laptop? And the base station?" Deputy stationmaster Xiao Nanfeng glanced at the list and asked in surprise.

Antarctica's network is a maritime line that uses satellite communication, and the speed is about 5 M/s, and you can only make phone calls.

Originally, this year, Telecom was going to come to Zhongshan Station to build a 3G base station, but it was suddenly canceled.

Anyone who has been to Antarctica knows that the network here is not only slow, but also intermittent, dropping at every turn, and charging is very expensive, a phone call may cost more than 500 yuan.

Zhang Chengcai, the stationmaster, also looked weird, but after he looked at it, he realized that this was a test project used to test satellite communications.

"Janssen."

"Zhang Zhan, what's the matter?" A spiritual guy in his early twenties sprang out from one side.

Zhang Chengcai patted the box and said, "Give you a task to install these two base stations." ”

"Base station?" When Janssen opened the box, there were two devices similar to routers, as well as some spare parts such as transformers and wires and cables.

He pulled out the manual, installed the two base stations on the east and west sides of Zhongshan Station according to the manual, and then turned on the switch.

"Where's the signal?" Janssen himself has a Nokia mobile phone, but he found that there was no signal at all, and it was still the same after turning it off and restarting.

After taking out the manual and reading it carefully, he realized that this was an experimental specimen and did not support communication other than terahertz.

Hurriedly took out a mobile phone from another box, it was a brand new smartphone, and considering the weather in Antarctica, there was also a pair of touchscreen gloves in the mobile phone box.

After putting on the touchscreen gloves, he found that the smartphone did not have a SIM card socket and did not provide a SIM card, in which case he had to turn to the manual.

"It turns out that the SIM card has been canceled." Yang Sen was talking to himself while following the instructions and directly binding it through his ID card.

After entering the mobile phone interface, this time I finally found that there was a signal.

XK346G…… What the heck? Memory? He looked at the few apps and tried to open the Citizen's House.

Hey? So fast! How can it be?

He didn't believe in evil and opened a video website and played an old movie directly, but the result was very smooth, and there was no lag and buffering at all.

Is it local storage? Yang Sen, who was puzzled, tried to dial the phone at home to see if this satellite communication could work.

A few seconds later.

"Hello? Who?" It's the mother's voice.

He didn't care about exploring the matter of satellite communication, and hurriedly replied excitedly: "Mom, it's me." ”

"Komori?" Mother asked, uncertain.

After talking for more than ten minutes, his mother in China confirmed that the phone was Yang Sen, and after hanging up the phone, he looked at the mobile phone in his hand and was too surprised.

However, he suddenly reacted and hurriedly opened the charge inquiry, don't fool people! After all, he can know very well the cost of the Internet in Antarctica, hundreds of dollars a minute.

[Dear users, since this service is in the trial operation stage, there is no charge for the time being, please fill in the user experience into the series of forms, and the company will continue to improve the relevant services...... ］

"Awesome!" Janssen hurriedly filled out the user experience form.

Then he took his mobile phone and ran over to the stationmaster Zhang Chengcai.

"Janssen, it's installed?"

"Alright." Yang Sen paused and continued: "Zhang Zhan, I found a good thing, you see. ”

After saying that, he turned on his phone, played the movie, and went to other websites.

"This ......" Zhang Chengcai looked at the mobile phone page dumbfounded, who uses the network in Antarctica and who knows, how did this mobile phone do it?

Yang Sen hurriedly explained, Zhang Chengcai and others took out the other 9 mobile phones and 5 laptops assigned to them, and after some trial, they found that this terahertz communication was really awesome.

Everyone hurriedly took their mobile phones to call their relatives in China to relieve their feelings of longing.

In this dark Antarctic ice field, loneliness is a problem that everyone must face, and the emergence of terahertz communication makes them excited, and finally they don't have to endure the expensive and cheating Internet.

However, terahertz communication is not available 24 hours a day, and there is only one group of satellite communication satellites passing through Antarctica, so there are three periods of time when Zhongshan Station cannot receive signals every day, and about 9 hours is a window period.

Even so, Zhang Chengcai and other members of the scientific expedition team are already very satisfied, and this kind of quality network was not even thought about before.

September 12th.

Antarctica was still dark, and under the embellishment of the aurora, Janssen and his three team members drove south in a sleigh car.

Their destination was Mount Tarzan Station, which is located on the south side of Princess Elizabeth Land, at higher latitudes, in the interior of Antarctica.

And Taishan Station is not their final destination, the final destination is Kunlun Station, is it in addition to the United States Amundsen? Outside of Scott Station, the second-highest latitude Antarctic research station.

And Janssen, who braved the snowstorm, found that his terahertz mobile phone could actually receive a signal, and the signal was very strong.

Everyone has to sigh that the motherland's science and technology are changing with each passing day, and even Antarctica, a natural desperate situation, can provide network services.

And it's not just that they are sighing, many of the Chinese ocean-going cargo ships that are being tested, or the people working in Heizhou, feel the power of terahertz communications.

If the density of satellites is larger, it can even cover the whole world and achieve global instant communication.

Through the satellite communication satellite in 915 kilometers of space, the thoughts of distant wanderers are turned into radio waves; and brought the nostalgia of his hometown to the wanderers.

The invisible radio waves bind us to each other.
