"In general, the advantages of the magic lamp Internet application are widely used and there is no electromagnetic radiation!"

Obviously, Gao Ning accepted Li Baoqiang's statement, not to mention, the magic lamp is still very appropriate.

Gao Ning told Li Baoqiang that compared with the currently popular IFI and optical fiber, lighting Internet has obvious advantages.

"The first is that the speed is fast, the spectrum of light Internet access is 400~800thz, and the current wireless Internet access is between 2~5GHz, and the former is tens of thousands of times higher than it."

Gao Ning said that this means that the lights have more bandwidth and higher speeds, and that their network setup requires little to no new infrastructure.

Compared with wireless Internet access, lighting Internet access is more economical.

At present, wireless Internet access relies on invisible radio wave transmission, the power of equipment is increasing, and local electromagnetic radiation is bound to increase, which has become an invisible "killer".

Because the light Internet uses the common visible light in life, it does not produce electromagnetic waves and does not contain radiation, so it does not cause any harm to the human body.

It is precisely because there is no electromagnetic interference that the lighting Internet can also be used in special scenes such as aircraft cabins and operating rooms, making space-ground communication possible.

In addition, the behavior of "rubbing the net" will also be terminated by the light on the Internet.

"Where there's light, there's a network signal. Turn off the lights and the internet is gone. No one else can rub your net. ”

Gao Ning said that because wireless signals can pass through walls, it may cause insecurity of network information. Security risks such as information leakage are "swept away" in visible light communication.

There's more to the Internet than meets the eye.

If the technology is mature, as long as there is an LED light, in the high-speed rail and restaurant, you can watch high-definition videos on your mobile phone, order food or call service;

It can also be used in places where radio waves cannot propagate well, such as underwater, so that the launching operation can also ensure smooth communication;

Perhaps the light Internet technology can also be applied to the lighthouse, which can send information such as the safety of the sea area to the distant ship, so that it can avoid risks and sail safely.

Of course, lighting Internet access may also be used in intelligent transportation.

In the future, LED street lights on both sides of the road can be used to send traffic information to passing cars at any time.

If two cars get too close together, there will also be a warning to avoid colliding.

It is precisely because of the advantages of lighting that the space research and development center decided to industrialize the scientific research results.

"The layman looks at the excitement, and there are a lot of technical problems in it. For example, increasing the rate is not so simple. ”

Gao Ning explained that the bandwidth of LED visible light is only 20M, and how to increase the transmission rate by increasing the bandwidth of LED is a difficult point.

"The response rate of the existing devices is almost close to the limit, and increasing the rate requires the use of new material devices and new system architectures."

"The next step is to improve the LED chip, using new technologies and materials to design the LED chip, so that it can meet the basic needs of lighting and play the role of a communication light source."

Pointing to the two black boxes, Gao Ning said that the transmission and reception systems of the light Internet are very large, and these two systems are made to the size of wireless network cards, which is the most ideal state. Chip miniaturization of existing systems will be the focus of her next research.

"In the next step, we will go all out to make chips. We have a leading algorithm to increase the rate, and if the chip is developed again, the lighting Internet technology will be more mature. However, because the production cost of chip integration is very expensive, it also needs the attention and investment of the Federal Space Research and Development Center. ”

Gao Ning said solemnly to Shangguan Yang, which could be regarded as a response to Shangguan Yang's question at the beginning.

"It's okay, it has to be supported, strongly supported!" Before Shangguan Yang could speak, Li Baoqiang was the first to speak.

Gao Ning stared at Li Baoqiang strangely, and then looked at Shangguan Yang.

I have long heard that the husband of Shangguan Yang's master is the chairman of the Federation, could it be that this black uncle is......

Heck, I still call him uncle, really.

Gao Ning's little face turned red all of a sudden.

"Hehe, researcher Xiao Gaoning, you can rest assured, your invention is very practical and promising, and the R&D center will fully support you to improve it and put it into production as soon as possible!"

Shangguan Yang smiled and reassured Gao Ning.

Gao Ning happily said goodbye to Shangguan Yang and Li Baoqiang, and deliberately glanced at Li Baoqiang before leaving.

Today I can be regarded as meeting the President of the Federation, the great leader, and I am so proud.

Looking at Gao Ning's healthy and agile figure, Li Baoqiang was very pleased, there are talented people in the Jiang Shang generation, and a generation of new people has replaced the old ones.

Li Baoqiang crossed his waist with his left hand, waved his right hand, and said in Hunan dialect: "The world is yours and ours, but in the final analysis, it is yours." You young people are full of vigor and prosperity, like the sun at eight or nine o'clock in the morning. Hope is in you. The world is yours. The future of the Earth Federation is yours! ”

"Hehe, you, now the shelf is getting bigger and bigger, but it's a little Handan toddler, it's not like that, you're still too young, wait until you're sixty years old to say that, it's still like that!"

Shangguan Yang couldn't help but smile and slapped Li Baoqiang again.

Li Baoqiang pretended to be injured: "Alas, I dare to beat the chairman of this federation, and the family law is serving!" ”

Fortunately, there was no one around, otherwise Li Baoqiang and Shangguan Yang would not dare to flirt like this.

Several agents laughed secretly in the corner, hehe, the chairman of the Federation is also an ordinary person, not as cold-blooded and ruthless as the legend says.

After laughing, Shangguan Yang said: "The technology of lighting the Internet is very interesting. Technological advances sometimes exceed people's imagination. 30 years ago, we would not have imagined that today's smartphones would be like this. But at the same time, it can take a long time for a new principle to become practical. For example, the fiber Raman amplifier was also a practical product 80 years after the principle was discovered.

The federal government must attach great importance to scientific research investment, which is related to the rapid development of the federation and the future of the federation! ”

Li Baoqiang also put away his smile and thought thoughtfully.

This visit to the Aerospace R&D Center has given Li Baoqiang a deeper understanding of the rejuvenation of the country through science and education.

VTOL small airliners are parked on the apron of the space center.

After inspecting the Universe R&D Center, Li Baoqiang and Shangguan Yang exchanged experiences while walking to the tarmac outside the door.

In today's world, the Federation has entered the space age, and scientific and technological innovation has played a major role in this period.

It is undeniable that those alien technology products have indeed given some inspiration and assistance.

Then the use of extraterrestrial technology and its transformation into actual effectiveness can only further illustrate that the level of science and technology education in various countries in the previous life played a key role.

If those incomplete alien antiques fall into the hands of people with no culture and no scientific research ability, they can only be a waste.

"After returning this time, I would like to propose that the federal government introduce measures to create a good cultural environment that respects knowledge and talent; strengthening the education system; Establish an effective system to support ......"

Li Baoqiang said his idea contemplatively, Shangguan Yang lowered his head and listened, and the agents and security guards gradually relaxed their vigilance in this leisurely environment.

Greeted by scientific researchers returning from a walk in twos and threes, a scientific researcher was obviously thinking about his thoughts, and lowered his head and bumped into Li Baoqiang's arms.

Li Baoqiang hurriedly dodged, suddenly felt a sharp pain, and looked closely, there was a bright table knife stuck in his chest.
