Chapter 366 Research and Development, Testing the Big Brother
In the following days, work in the laboratory entered an unprecedentedly busy stage.
Li Yang led the team to work day and night to solve one technical problem after another.
From signal modulation to circuit design, from battery optimization to antenna improvement, every link embodies their wisdom and sweat.
One night, when everyone else had gone back to rest exhausted, Li Yang was still standing in front of the lab table, concentrating on debugging a complex circuit board. His eyes were a little red from working for a long time, but his eyes were still firm.
Suddenly, an indicator light on the circuit board lit up, and Li Yang's eyes lit up. He quickly picked up the microphone connected to the circuit board and whispered, "Test, test."
A clear echo came from the other end of the microphone: "Received, signal clear."
Li Yang showed a gratified smile on his face. This was the first time they had successfully achieved wireless voice transmission. Although the distance was still short, it was undoubtedly an important breakthrough.
At this moment, Zhang Guoqiang pushed the door open and walked in. Seeing that Li Yang was still working, he couldn't help but shook his head and laughed: "Mr. Li, why don't you rest so late?"
Li Yang turned around with a tired but excited smile on his face: "Guoqiang, you're just in time. We just made an important breakthrough, come and listen."
He motioned Zhang Guoqiang to pick up another microphone, and then he walked to the other end of the room. "Hello, Guoqiang, can you hear me?" Li Yang's voice reached Zhang Guoqiang's ears through the radio waves.
Zhang Guoqiang's eyes widened in surprise: "This is amazing, Mr. Li! Is this a wireless phone?"
Li Yang nodded with a proud smile on his face: "Yes, although we can only communicate within a very short distance now, this is an important start. Next, we will continue to optimize the design to improve the transmission distance and signal quality."
Zhang Guoqiang said excitedly: "That's great, Engineer Li. I will report this good news to my superiors right away."
Li Yang waved his hand: "Don't worry, Guoqiang. We still have a long way to go. This is just a small success, and the real challenge is still ahead."
He walked to the window and looked at the night sky in the distance. The moonlight shone on his face, reflecting a resolute outline. "We not only need to develop a usable wireless phone, but also build a complete communication network. This requires a large number of base stations, a complex signal processing system, and many technical problems to be solved."
……
The lights in the laboratory stayed on until late at night. Li Yang and his team experienced countless challenges and setbacks during the development of wireless phones. Every moment of persistence laid the foundation for future changes.
Li Yang stood in front of the experimental bench, holding a new type of circuit board in his hand, his brows furrowed.
Inside the laboratory, the air was filled with a strong smell of tea. The walls were covered with densely packed sketches and formulas, and there were a lot of discarded materials scattered on the ground.
The team members were all working hard, some were debugging equipment, and some were pondering the formulas on the whiteboard.
"The stability of signal transmission is still not enough." Li Yang muttered to himself, his eyes fixed on the circuit board in his hand, as if trying to find out what the problem was.
"Mr. Li, look here." A young engineer, Xiao Wang, came over with a new antenna design in his hand. "I adjusted the angle of the antenna slightly, which can effectively reduce signal interference."
Li Yang took the drawing, looked at it carefully for a moment, and nodded.
"This design is good. Let's give it a try." He turned around and handed the blueprint to the technician next to him, and instructed: "Make another set of samples according to this plan."
At the same time, another engineer, Xiao Li, was struggling to figure out how to reduce the power consumption of the equipment.
The table was filled with various circuit boards and chips, and his face was full of fatigue. He scratched his hair, and suddenly an idea flashed in his mind, and he hurried to Li Yang.
"Mr. Li, maybe we can try using a new type of low-power chip, which can significantly extend the battery life."
A glimmer of hope flashed in Li Yang's eyes, and he patted Xiao Li on the shoulder. "Okay! Your idea is very good, go and experiment right away."
The whole team is working towards a common goal. They know that any negligence in a detail could lead to a total failure. Countless experiments and failures have almost worn down their will, but every time a new idea comes up, the flame of hope is rekindled in everyone's eyes.
"The power consumption problem has been solved, but the appearance design is not ideal enough." Li Yang pointed out at the meeting, his eyes swept over each team member, his expression serious and determined. "We need to design a design that is both ergonomic and memorable."
Designer Xiao Chen immediately took over the topic. He sketched out several different appearance designs, combined with the popular industrial design style at the time, trying to find the best balance between beauty and practicality. "Mr. Li, I think this curved design is more ergonomic and more comfortable to hold in the hand."
Li Yang looked at the sketch, thought for a moment and nodded. "Not bad, let's improve the details, the key is to grasp the user's usage habits." He believed that details determine success or failure, this mobile phone should not only be practical, but also be loved by people.
……
Finally, after countless days and nights of hard work, the various components were developed one after another. Li Yang led the team into the final assembly stage. In the production workshop, the roar of machines came one after another, and the technicians were concentrating on carefully assembling each component together.
Li Yang personally stood on the assembly line, watching every detail of the operation. Whenever he found anything that did not meet the standards, he would immediately point it out and ask for readjustment. The assembly work did not allow for any sloppiness, because this mobile phone carried too many expectations.
"Be careful not to let any welding points become loose." Li Yang reminded from time to time while inspecting.
After the assembly was completed, the team immediately began debugging. Each mobile phone was placed on the test bench, connected to various measuring instruments, and the engineers were busy testing various functions.
"The call quality is good, but there is some noise." Xiao Wang frowned during the test and looked up at Li Yang.
Li Yang walked to the test bench, picked up a microphone, and listened carefully to the noise in the call. "Well, the signal in this frequency band may be interfered with. Adjust the parameters of the filter and try again." He gave the order calmly, but he was not at ease.
Battery life is also a major problem. Repeated tests have shown that although a new low-power chip has been adopted, the battery durability still does not meet Li Yang's expectations. "The battery design needs to be further optimized." He reiterated at the meeting, his eyes as firm as iron.
Zhang Guoqiang took out his pipe, put it in his mouth, and took a puff. The smoke lingered between his worried brows. "Engineer Li, time is running out. Can we try another plan?"
Li Yang pondered for a moment and suddenly slapped the table. "We can try a dual-battery parallel design, or use battery materials with higher energy density." He didn't have time to wait, he knew that only by continuous experimentation could he find the best solution.
A few days later, the new battery design finally passed the test, and the battery life was significantly improved. Li Yang finally smiled, but he knew that the next debugging work still needed to be done.
In the laboratory, Li Yang's team conducted multiple tests on the mobile phone. They invited some volunteers to try it out, and the volunteers excitedly picked up the mobile phone and felt the new experience brought by this revolutionary product.
"It's amazing!" A volunteer holding a mobile phone was full of surprise. "The call sound is very clear and the operation is very convenient."
Li Yang stood aside and nodded with satisfaction, but he was not satisfied with this. He knew that the laboratory environment was limited after all, and only in a real environment could the performance of this device be truly tested.
Thus, a more comprehensive test began. Li Yang led the team members out of the laboratory and into every corner of the city. They shuttled through the city center with tall buildings, entered dark and narrow tunnels, and even climbed the surrounding mountains. They held their cell phones and carefully recorded every detail, fearing that they would miss any factors that might affect the signal.
"The signal is a bit unstable between tall buildings." Xiao Li said to Li Yang anxiously while standing on the rooftop of a skyscraper.
Li Yang stared at the mobile phone in his hand, frowning. "Maybe the metal structure of the building is blocking the signal. Adjust the antenna angle and try to optimize the transmission algorithm."
After repeated adjustments, they finally made the signal stable even in complex urban environments. During the test in the mountainous area, the signal was sometimes strong and sometimes weak, which put the team members in a dilemma. However, Li Yang did not give up. He led the team to test back and forth on the mountain road, and finally successfully solved this problem by fine-tuning the antenna angle and further optimizing the algorithm.
"Engineer Li, now we can rest assured." Zhang Guoqiang stood on the top of the mountain, looking at the city in the distance, and breathed a sigh of relief.
Li Yang wiped the sweat from his forehead and nodded. "But we can't let our guard down yet. We need to do more testing to ensure that it can work stably in any environment."
……
One morning, the laboratory received a notice that several senior leaders would come to inspect the development progress of the mobile phone. Li Yang immediately organized the team to prepare for this important inspection.
