Chapter 365 Radio Chapter Thoughts
As Li Yang and his team walked into the communications laboratory, a tense and excited atmosphere filled the air.
The young researchers gathered around a huge device, their eyes gleaming with victory.
Li Yang walked forward quickly and carefully observed the flashing indicator lights and the constantly jumping data on the equipment.
"We succeeded, Mr. Li!" a middle-aged researcher with a thick beard said excitedly, "We successfully increased the signal transmission distance to 50 kilometers, and the signal quality is 30% higher than before!"
Li Yang nodded and a relieved smile appeared on his face.
This was indeed a significant improvement, but he knew in his heart that there was still a long way to go before a real breakthrough.
His eyes swept across the busy figures in the laboratory, and suddenly, a bold idea flashed in his mind.
"Everyone," Li Yang's voice made everyone stop what they were doing, "We have made great progress in wired communications, which is great. But have you ever thought about what it would be like if we could get rid of these cables and achieve true wireless communication?"
The lab suddenly fell silent, and everyone was attracted by Li Yang's words. Zhang Guoqiang frowned and said thoughtfully: "Engineer Li, are you talking about... wireless phone?"
Li Yang's eyes lit up. "Yes, it's a wireless phone. Imagine if we could talk to others anytime and anywhere, regardless of geographical location, how much it would change our lives and work!"
He walked over to the whiteboard, picked up a marker and started drawing. "We need to develop a portable wireless communication device that is small enough to carry with you. At the same time, we also need to build a base station network with wide coverage to ensure stable signal transmission."
Li Yang's words instantly made the atmosphere in the laboratory boil. The researchers discussed excitedly and put forward their own ideas and suggestions. Zhang Guoqiang looked at Li Yang thoughtfully. He knew that this seemingly crazy idea might completely change the way of communication in the future.
At this moment, a young researcher suddenly asked: "Mr. Li, is the wireless phone you are talking about like the walkie-talkie we use now?"
Li Yang smiled and shook his head. "No, Xiao Wang, our goal is much greater. Let me tell you about the development of wireless communications."
He walked to the window and looked at the sky in the distance, as if he saw the scene of the future.
The history of wireless communication can be traced back to the end of the 19th century when people began to use wireless telegraphs, but the real mobile communication started with the wireless walkie-talkie in the 20s.
Wireless walkie-talkies were mainly used for military communications. They were bulky and needed to be carried on the back. In the late 50s, Bell Laboratories in the United States developed the first generation of cellular mobile phone systems, which was an important milestone in the development of mobile communications.
However, it was the "big brother" that appeared in the early 80s that really made mobile phones enter the lives of ordinary people. Although it was still very heavy, it could be put in a suitcase and carried around.
Li Yang walked back to the whiteboard and drew a rough shape of a "mobile phone" on it.
"This is just the beginning. As technology develops, communication devices will become smaller and lighter, and their functions will become more and more powerful. In the end, we will see truly portable mobile phones that can easily fit in your pocket."
His eyes sparkled with wisdom, as if he had already seen the future.
In the 21st century, mobile phones will no longer be just tools for making calls. They will become multi-functional mobile terminals that can be used to surf the Internet, take photos, watch videos, and may even become indispensable smart assistants in our lives.
Everyone in the lab was fascinated by what Li Yang was saying. Although they could not fully understand the future that Li Yang described, they could all feel the infinite possibilities it contained.
Li Yang took a deep breath and pulled his thoughts back to reality. "But now, we have to start from the basics. Our goal is to develop the first generation of wireless phones."
He turned to face the team, his eyes full of determination and expectation. "To achieve wireless communication, we need to solve several key problems. The first is the transmission and reception of signals. We need to develop equipment that can transmit voice signals over long distances. The second is the allocation and management of frequencies. We need to establish an effective frequency usage mechanism to avoid signal interference."
Li Yang walked to the whiteboard and began to draw a simple network structure diagram. "The most important thing is that we need to build a base station network. Each base station is responsible for sending and receiving signals within a certain area. When a user moves from the coverage area of one base station to another, the system must be able to automatically switch to ensure that the call is not interrupted."
He stopped writing and turned to face the team. "It goes without saying how difficult this task is, but I believe that as long as we work together, we will succeed. Now, let's get started."
As soon as Li Yang finished speaking, the whole laboratory was in an uproar. The researchers were discussing excitedly, and they all put forward their own ideas and suggestions. Zhang Guoqiang walked up to Li Yang and whispered, "Engineer Li, I'm afraid this project will require a lot of manpower and material support."
Li Yang nodded, a hint of determination flashing in his eyes. "Yes, we need more support. Guoqiang, go report our plan to your superiors and see if we can get more resource support."
Zhang Guoqiang nodded solemnly and left the laboratory. Li Yang took a deep breath and walked to a blank design table. He picked up a pencil and began to sketch the prototype of the first generation of wireless phones on paper.
First, Li Yang drew a rectangular shell, about the size of a shoe box. "The shell must be strong enough to protect the electronic components inside," he said to himself, "and the heat dissipation problem must also be considered."
Then, he began to design the internal structure. "The antenna is the key," Li Yang muttered to himself, drawing a retractable antenna on the blueprint, "We need a retractable antenna that can ensure signal strength without affecting portability."
Li Yang's pen moved quickly on the paper, and soon he sketched out a preliminary internal structure diagram. "The battery is another difficulty," he frowned and thought, "We need a battery with a large enough capacity but not too heavy."
Just then, a young researcher came over. "Engineer Li," she said hesitantly, "I was wondering if we could use nickel-cadmium batteries? They have a higher energy density than lead-acid batteries and can be recharged repeatedly."
Li Yang's eyes lit up. "Good idea!" He looked at the young researcher approvingly. "Nickel-cadmium batteries are indeed a good choice. However, we still need to consider how to extend the battery life."
He marked the location of the battery on the drawing and began to design the circuit. "We need an efficient signal processor," Li Yang said, drawing continuously with his hands, "it must be able to quickly convert voice signals into electronic signals and perform encryption processing."
Li Yang stopped writing and carefully examined his design. "There is another key issue," he pondered, "that is how to implement call switching. When a user moves from one base station coverage area to another, we need to ensure that the call is not interrupted."
He walked to the whiteboard and began to draw a simple network structure diagram. "We need to design a central control system," Li Yang explained, "which is responsible for coordinating the work of each base station, monitoring the location of each user in real time, and switching calls when necessary."
At this moment, Zhang Guoqiang walked in with an excited expression on his face. "Engineer Li, good news! Our superiors attach great importance to our project and have agreed to increase investment and dispatch more researchers to support us."
Li Yang nodded, a pleased smile on his face. "Great, with this support, our research and development work can be accelerated." He turned to the other people in the laboratory, "Ladies and gentlemen, our task is arduous and glorious. We not only have to develop the first generation of wireless phones, but also lay the foundation for future development. Let us work together to create history!"
There was a burst of warm applause and cheers in the laboratory. Everyone's face was filled with pride and anticipation, knowing that they were participating in a great cause that could change the world.
Li Yang took a deep breath and looked at the design again. He knew that there were still countless difficulties and challenges waiting for them. But he firmly believed that as long as they persevered, they would eventually succeed and write a new chapter for Yan's communications industry.
