"In general, the magic lamp Internet application has the advantages of wide range of uses and no electromagnetic radiation,"

Obviously Gao Ning accepted Li Baoqiang's statement, let alone, the magic lamp goes online, it is still very appropriate.

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

"The first is high speed. The spectrum for lighting Internet access is 400-800thz. The current spectrum for wireless Internet access is between 2-5ghz. The former is tens of thousands of times higher."

Gao Ning said that this means that the lighting Internet has greater bandwidth and higher speed, and its network settings require almost no new infrastructure.

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

The current wireless Internet relies on invisible radio wave transmission. As the power of equipment becomes larger and larger, local electromagnetic radiation is bound to increase, which has become an invisible "killer".

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

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

In addition, the behavior of "using the Internet" will also be terminated by the Internet.

"Wherever there is light, there is a network signal. If you turn off the light, there will be no network at all, and others will not be able to access your network."

Gao Ning said that because wireless signals can pass through walls, network information may be insecure, and potential security risks such as information leakage can be "swept away" in visible light communications.

The imagination about lighting Internet is not limited to the above.

If the technology matures, as long as there is an LED light, you can watch high-definition videos, order food or call services on your mobile phone in high-speed trains and restaurants;

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

Maybe the lighting Internet technology can also be applied to lighthouses. Lighthouses at sea can send information such as the safety level of the sea area to distant ships, so that they can avoid risks and sail safely.

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

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

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

It was precisely after seeing the advantages of lighting on the Internet that the Universe R&D Center decided to industrialize scientific research results.

"For laymen, there are many technical problems involved. For example, increasing the speed is not that simple,"

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

"The response rate of existing devices is almost close to the limit. To increase the rate further, new materials, devices and new system structures are required,"

"The next step is to improve the LED chip and use new technologies and materials to design the LED chip so that it can function as a communication light source while meeting the basic needs of lighting."

Pointing to the two black boxes, Gao Ning said that the transmitting and receiving systems for lighting Internet access are very large. It is ideal to make these two systems the size of wireless network cards. Miniaturizing the chips of the existing systems will be her next step. The focus of further research.

"Next we will go all out to make chips. We have a leading speed-increasing algorithm. 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 will also require a federal universe. The attention and investment of the R&D center,”

Gao Ning said solemnly to Shangguan Yang, which was also his response to Shangguan Yang's question at the beginning.

"This is no problem. We must support it and strongly support it," Li Baoqiang was the first to express his position before Shangguan Yang could speak.

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

I have long heard that Master Shangguanyang’s husband is the Federation Chairman. Could it be that this black uncle is...

Heck, I even called him uncle, really.

Gao Ning's face suddenly turned red.

"Haha, researcher Xiao Gaoning, don't worry, your invention is very practical and promising. The R&D center will fully support your improvement and put it into production as soon as possible."

Shangguan Yang gave Gao Ning a reassurance with a smile.

Gao Ning happily said goodbye to Shangguanyang and Li Baoqiang, and took a special look at Li Baoqiang before leaving.

Today I met the president of the Federation, a great leader, and I am so proud of him.

Seeing Gao Ning's healthy and agile figure, Li Baoqiang was very pleased. There were talented people in the previous generation, and a new generation replaced the old one.

Li Baoqiang put his left hand on his hips, 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, just like the sun at eight or nine o'clock in the morning. Hope I place my trust in you, the world belongs to you, and the future of the Earth Federation belongs to you,"

"Haha, you, your arrogance is getting bigger and bigger now, but it's a bit like a toddler, it doesn't look like that. You are still too young. If you say that when you are sixty, it will still look like that."

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

Li Baoqiang pretended to be injured: "Oh, how dare you beat the chairman of this federation, I will take care of you,"

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

Several agents snickered in the corner, haha, the Federation Chairman is also an ordinary person, not as cold-blooded and ruthless as the legend says.

After laughing for a while, Shangguan Yang said seriously: "The technology of lighting Internet is very interesting. The development and progress of science and technology sometimes exceed people's imagination. 30 years ago, we would not have thought that today's smartphones would be like this, but at the same time, a new It may also take a long time for the principle to become practical. For example, fiber Raman amplifiers only had practical products 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 looked thoughtful.

This trip to the Aerospace R&D Center gave Li Baoqiang a deeper understanding of rejuvenating the country through science and education.

A small vertical take-off and landing passenger aircraft is parked on the apron of the space center.

After inspecting the Space R&D Center, Li Baoqiang and Shangguan Yang walked to the tarmac outside the door while exchanging their thoughts. The two always thought:

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

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

So the use of alien technology and its transformation into actual effectiveness can only further prove that the level of science and technology education of various countries in previous lives played a key role.

If those incomplete alien antiques fall into the hands of people with no culture or scientific research capabilities, they can only be trash.

"After returning this time, I would like to propose that the federal government introduce measures to establish a good cultural environment that respects knowledge and talents; strengthens the construction of the education system; establishes an effective institutional support..."

Li Baoqiang talked thoughtfully about his ideas, Shangguan Yang lowered his head and listened, and the agents and security guards gradually relaxed their vigilance in this leisurely environment.

Facing them were scientific researchers returning from a walk in twos and threes. One researcher was obviously thinking about something, and he lowered his head and bumped into Li Baoqiang's arms.
