Chapter 115 H-Link Communication Base Station
Before the shock of the audience had subsided, Su Chen had already moved on to the next segment.
He slightly raised his hand, signaling for silence, and then spoke as the LED screen switched images:
"The adaptive channel tracking technology just demonstrated solves the problem of 'precise signal delivery'—ensuring that every bit of communication energy is delivered precisely to the target without being wasted."
"But the challenges facing low-altitude communication go far beyond this."
Su Chen's voice became even more composed:
"As is well known, the low-altitude flight environment is extremely complex. Obstruction and reflection from urban buildings, electromagnetic interference from high-voltage power lines, spectrum congestion from various civilian wireless devices… these factors combine to make the low-altitude communication environment more than ten times worse than ground-based communication."
Traditional communication solutions typically operate on a single frequency band, such as 2.4GHz—which offers strong penetration and wide coverage, but limited speed. Furthermore, this band is crowded with WiFi routers, Bluetooth devices, and microwave oven radiation, causing severe interference.
"For example, 5.8GHz has a large bandwidth and high speed, making it suitable for high-definition image transmission, but its penetration is weak, and the signal attenuates drastically when it encounters buildings that block it."
Su Chen paused here, looking at the audience members nodding frequently below the stage, a smile appearing on his lips:
"But is the weak penetration of 5.8GHz really just a drawback?"
This statement surprised many people at the scene.
Many of you here work in the drone industry, and in your minds, the stronger the penetration of communication signals, the better. Weak penetration means connection loss due to obstruction, and limited flight range—how could that be an advantage?
Su Chen smiled, and then uttered a point that made many people suddenly realize something:
"Weak penetration means your signal won't penetrate into adjacent airspace. In urban low-altitude environments, there might be a dozen drones from different companies performing missions simultaneously in a single building. If all drones use low-frequency communication with extremely strong penetration, their signals will interfere with each other, severely degrading the communication quality of the entire airspace."
"The weak penetration of 5.8GHz signals creates natural spatial isolation—your signal won't interfere with drones in the next building, and their signals won't interfere with yours. In the dense urban low-altitude environment, this is actually a huge advantage!"
"I see!"
Han Shijie, sitting in the third row of the VIP section, had a look of sudden realization on his face.
As the head of Xingyao Technology, his team of engineers has been working in the field of communication modules for more than a decade, but no one has ever thought about the "disadvantages" of the 5.8GHz band from this perspective.
Indeed, everything exists for a reason. The choice of frequency band is not simply a matter of high or low, superior or inferior; it requires making the optimal combination based on the application scenario!
Su Chen's technical vision is indeed unmatched by ordinary people!
"so--"
Su Chen's voice rose by half a tone:
"Next, I will demonstrate the second core technology of the H-Link communication framework—air-to-ground cooperative networking technology!"
"Air-Ground Cooperative Networking Technology!"
Upon hearing this name, Chen Jiaming's eyebrows twitched.
He suddenly realized that what Su Chen was going to do was much bigger than he had imagined—if adaptive channel tracking solved the problem of "point-to-point communication", then air-to-ground collaborative networking solved the problem of "communication architecture of the entire airspace"!
This is not just a product; it's a complete set of airspace communication standards!
The large screen switched again, displaying a new set of test data and animated demonstrations.
The animation depicts a low-altitude urban scene: dozens of drones fly simultaneously at different altitudes and in different directions. Multiple H-Link base stations are distributed on the ground, interconnected via a wired backbone network.
And then the crucial part appeared—
Each H-Link base station communicates simultaneously on three frequency bands:
900MHz band: Used for ultra-long-distance command control and status feedback. It has extremely strong penetration and lower bandwidth, but it is stable and reliable. It can maintain a stable control link even at a distance of five to eight kilometers.
2.4GHz band: Used for medium-distance data transmission, balancing coverage and transmission rate, suitable for telemetry data and low bitrate video backhaul.
5.8GHz band: Used for high-speed data transmission over short distances, supporting the backhaul of high-definition image transmission, point cloud data, and real-time AI inference data, with speeds reaching hundreds of megabits per second.
What's most impressive is that these three frequency bands don't simply operate independently, but are managed uniformly by the intelligent scheduling algorithm of H-Link base stations.
When the drone is flying at close range, the base station automatically switches the high-definition image transmission data to the 5.8GHz band for the highest speed. When the drone flies further away, the base station seamlessly downgrades the image transmission to 2.4GHz, while switching critical control commands to 900MHz to ensure uninterrupted communication. When the drone enters an obstructed area, the algorithm automatically selects the optimal frequency band combination within milliseconds to ensure uninterrupted communication.
The entire process is fully automated, and the drone operator does not need to perform any operations!
"Next, please look at a set of actual measurement data."
As soon as Su Chen finished speaking, a complete comparison data table popped up on the big screen.
The audience erupted in another uncontrollable gasp!
Because the data discrepancies in the table are simply too great—
Effective communication distance:
Traditional 2.4GHz image transmission solution: 1.5-2 kilometers
4G DTU relay: Depends on base station coverage, approximately 3 kilometers in urban areas.
A certain brand's high-end image transmission system: 3.5 kilometers.
LDCL standard module: 4 km
H-Link Pro (Tri-band Synergy): 8.2 km
H-Link Lite (Tri-band Synergy): 6.5 km
End-to-end communication latency:
Traditional 2.4GHz solution: 150-220ms
4G DTU relay: 120-300ms (extremely fluctuating)
High-end image transmission for a certain brand: 80-100ms
LDCL standard module: 90-130ms
H-Link Pro: 8-15ms
H-Link Lite: 12-22ms
Simultaneous control of the number of drones (single base station):
Traditional plan: 1-3 aircraft
A certain brand's solution: 1 aircraft (point-to-point)
LDCL standard module: 5-8 units
H-Link Pro: 40 units
H-Link Lite: 20 units
Electromagnetic interference resistance (out of 10 points):
Traditional 2.4GHz solution: 3 points
4G DTU Repeater: 5 points
High-end image transmission for a certain brand: 6 minutes
LDCL standard module: 6 points
H-Link Pro: 9.2 points
H-Link Lite: 8.5 points
Upon seeing these figures, the nearly one thousand people in the audience fell into a brief silence.
Then came an explosive round of applause!
"This is insane! This is absolutely insane!"
Chen Weiguo was so excited that he slapped his thigh. His colleague next to him—a boss who made power line inspection drones—had already stood up excitedly.
An effective communication range of 8.2 kilometers! What does this mean? It means that when his agricultural drone is operating in mountainous and hilly areas, he no longer has to worry about losing contact after crossing a hill!
A single base station can simultaneously control 40 drones! What does this mean? It means that large-scale drone swarm operations have become a reality at the communication level for the first time! Previously, one pilot could only control one drone; now, one operator, working with an H-Link Pro base station, can simultaneously command an entire swarm!
Communication latency of less than 15ms! What does this mean? It means that every command from the ground operator arrives almost in real time, and the remote control operation of the drone will have the same instant response as a game controller!
Cheng Weiyuan, sitting in the front row, had become extremely serious.
As the deputy director of Huawei's Low-Altitude Intelligent Connectivity Lab, he knew all too well what these data meant. Huawei's lab had only been established for two months, and their first prototype solution had a communication latency of around 85ms, an order of magnitude lower than Hongyuan's level.
Hongyuan already has mass-produced hardware products.
This gap... is at least a year and a half. Su Chen's previous judgment was correct, but Cheng Weiyuan did not expect the gap to be so large.
As you can see—
Su Chen's voice rang out again, calm and confident:
"Our H-Link air-to-ground communication base station surpasses all current solutions on the market in all core indicators. And the foundation of all this is our independently developed H-Link 2.0 low-altitude communication protocol standard."
"The H-Link 2.0 standard is backward compatible with all mainstream drone communication protocols currently on the market, including but not limited to the LDCL standard, proprietary image transmission protocols from mainstream manufacturers, and standard 4G/5G data links."
In other words, you don't need to replace your existing drones! You only need to deploy an H-Link base station on the ground, and all your existing drones can immediately benefit from the H-Link communication framework!
"Of course, if your drone is equipped with a native H-Link communication module—which is the third product we're releasing today—then you'll get the full performance of the H-Link 2.0 standard!"
The applause erupted once again.
Su Chen slightly raised his hand, and the screen switched to the price page of the two base stations.
H-Link Pro air-to-ground communication base station: 2999 yuan
H-Link Lite air-to-ground communication base station: 999 yuan
Upon seeing these two prices, the entire audience was initially stunned, then erupted in even more enthusiastic applause and cheers than before!
999 yuan!
H-Link Lite is only 999 yuan!!!
It's worth noting that the cheapest professional-grade ground base station on the market that can achieve stable long-distance communication costs at least 15,000 yuan, while a complete set of LDCL standard communication modules and matching ground equipment costs at least 30,000 yuan!
And Hongyuan's H-Link Lite—H-Link Lite whose performance crushes all traditional solutions—is only 999 yuan?!
Even the H-Link Pro, which boasts even more terrifying performance, is only 2999 yuan!
This pricing is practically a massacre of the entire telecommunications equipment industry!
Chen Weiguo was so excited he almost stood up. The power company inspector next to him was already pulling out his phone: "Where do you think we can buy them after the press conference? The official website? I'll order twenty!"
"Don't rush, don't rush, I haven't finished yet." Chen Weiguo said this, but his own hands were trembling slightly.
At 999 yuan per unit, a team of twenty people equipped with several units, along with the flight control module from the Flying Bird platform, completely solved their communication problems for plant protection operations in hilly and mountainous areas! How much loss due to loss of communication can be saved in a year? 100,000? 200,000?
Su Chen is simply a savior for small and medium-sized business owners like them!
Meanwhile, Liu Boyuan, the technical vice president of Hangxindatong, who was sitting in the back corner, looked extremely grim.
999 yuan. Hongyuan has priced the H-Link Lite at 999 yuan.
Hangxindatong charges 40 million yuan to license its LDCL to a company (the price after Su Chen cut it down), and the licensed company charges 30,000 yuan for a set of LDCL communication modules and equipment.
Hongyuan now offers a communication solution with performance several times higher than the LDCL standard for only 999 yuan.
This isn't competition; this is a devastating blow.
Liu Boyuan glanced down at his phone; He Zhiqiang had just sent a message with only two words: "Continue."
He continued recording with a bitter expression.
"These two H-Link base stations will be available for pre-order immediately after the launch event, with the first batch of 3,000 units to be shipped before August 15th."
Su Chen's voice sounded remarkably calm amidst the excitement of the entire audience:
"You can place your order through Hongyuan Intelligent's official website, the Feiniao Open Platform official store, and the Hongyuan flagship store on JD.com."
Before he could finish speaking, his tone suddenly became meaningful:
"Finally—we'll be releasing our last product of the day."
The entire audience's attention was instantly drawn to its peak.
Everyone knows that the third product is the flight control and communication integrated module with a dense chipset—this is the real trump card of today's press conference!
Su Chen smiled slightly, and the palm-sized module on the big screen was magnified and displayed, with every chip and every interface clearly visible.
"This product is the world's first low-altitude flight core module that integrates a flight control processor, H-Link 2.0 communication baseband, adaptive channel management engine, and BeiDou/GPS dual-mode navigation."
Its name is—
Su Chen pointed to the large screen, and three large characters slowly appeared:
Asuka S1
"Asuka S1?"
Many people at the scene showed subtle expressions after hearing the name.
Because of the name "Flying Bird," it has acquired a very distinct label in the entire drone industry—that is, a high-performance, cost-effective flight control platform for small and medium-sized enterprises. The basic version costs 499 yuan, the professional version costs 699 yuan, the enterprise version costs 999 yuan... The name "Flying Bird" is almost synonymous with "cheap and easy to use, but not high-end."
Now Su Chen is also calling this product, which integrates multiple cutting-edge technologies and is clearly positioned as a flagship product, "Flying Bird"?
Sitting in the middle of the audience, a young entrepreneur making aerial drones couldn't help but mutter to the person next to him, "This product is really amazing, but isn't the name a bit off? 'Flying Bird S1' sounds like it's from the same series as their basic flight controller that costs 490 yuan..."
"Exactly," someone nearby whispered in agreement. "If I used this module to make a high-end product and told the client that the core technology was 'Flying Bird,' wouldn't the client's first reaction be that I used that cheap 490 yuan thing?"
"Besides, the name 'Flying Bird' itself isn't very good. Other companies' 'FlightCore' and 'SkyLink' sound so high-end, while our 'Flying Bird' sounds like a sparrow..."
Similar discussions arose from the audience.
Many people admire the technology and performance of the Asuka S1, but have reservations about its name.
In their view, Su Chen is a genius in product development, but he is clearly lacking in brand naming skills.
Is this flagship product, which integrates adaptive channel tracking, air-to-ground cooperative networking, and the H-Link 2.0 protocol, called "Flying Bird S1"?
How can anyone maintain such a high-class image?
They could already imagine this scenario: at a high-end industry exhibition, when they proudly showcased their flagship drone equipped with the Flying Bird S1 and introduced to customers that "our core module comes from Hongyuan's Flying Bird series," a subtle expression would surely flash across the customer's face...
"Asuka? You mean that flight controller that costs 490?"
Then all the carefully crafted high-end image collapsed instantly.
But despite the complaints, everyone present understood that the name was just a facade, and the product was the core.
If the performance of the Flying Bird S1 is as powerful as Su Chen demonstrated, then even if it were called "Shovel No. 1," people would still rush to buy it.
Meanwhile, Su Chen on stage seemed completely oblivious to the whispers about his name from the audience.
He simply smiled slightly, and then said something that made everyone prick up their ears:
"I'll show you the full specifications and pricing of the Asuka S1 later. But before that—"
Su Chen's gaze swept across the entire venue, and under the watchful eyes of hundreds of expectant people, a slow smile curved his lips:
"I have some special news to announce."
The entire room fell silent instantly.
Everyone held their breath.
Even Xia Kanghao, who was expressionless in the back corner, slightly raised his eyelids.
Meanwhile, Zhou Zhenguo of Lianchuang Group, who was sitting in the middle of the third row—a man who had traveled thousands of miles back from the United States after changing his flight—finally revealed a knowing smile.
Because he knew that what Su Chen was about to announce was the real bombshell of today's press conference.
