Fan Xiaofan blinked, then took out a piece of paper and demonstrated it to Shi Moyun.
"If we set up a signal station here, using a sailboat sailing at sea as an analogy, wouldn't the magnetic field be detectable and the signal received within a certain radius of a sailboat? ... The coverage area of such a signal station is limited, but what if it covers multiple layers?"
Shi Moyun was somewhat surprised. It turned out that some incredible research could actually be explained by the most ordinary principles in the end.
Fan Xiaofan then said with a smile, "However, there's no rush. We need to get the most basic facilities up and running first, then these won't be a problem later..."
Shi Moyun, who was holding the paper and deep in thought, subconsciously glanced at Fan Xiaofan...
"Although mobile phones will bring great convenience to people if they are studied, we have not yet perfected their foundation. It is like building blocks. If the base is not well built and we only think about the view from the top, it will be like a house without a foundation, which is easy to collapse."
"So what you mean is?"
Shi Moyun coughed twice. Honestly, it was all because he was too excited when he heard about this project in the office that day, and for a moment he didn't think as thoroughly as Fan Xiaofan. Of course, he would never admit it.
After all, he still needs to save face as a vice dean.
"It's electricity. Electricity isn't widely used these days. Many villages still use kerosene lamps for lighting, and they have to carefully count their kerosene coupons. As for mobile phones, even the most basic hand-cranked telephones don't have high coverage. Many villages and even work units only have one..."
Shi Moyun's brows furrowed more and more as he listened. He should have thought of this earlier than Fan Xiaofan.
But perhaps it was a case of "why not eat meat porridge?" He grew up in Beidu from a young age, and everything he was exposed to was the best environment, whether at home or in the research lab. In this respect, he never felt troubled...
"Now I think that sending educated youth to the countryside may not necessarily be a bad thing."
Shi Moyun couldn't help but sigh, "When people are in one position for a long time, even if they work hard, they often overlook what the people really need."
When Emperor Hui of Jin learned that the people were starving, he kindly offered suggestions. Little did he know that the people couldn't even get enough grain, so how could they possibly have meat?
The following day, Shi Moyun made a special trip to learn about the electricity situation. She was shocked to find that even in Beidu, the most developed city, electricity coverage was not widespread and the cost was high, making it unaffordable for many people. They were still using the oldest lighting methods.
As for telephones, as Xiao Fan said, even the worst hand-cranked telephones are probably only found in important units. In residential areas, it's considered good if there's one in a large courtyard.
If this is the case in the capital, what about the rest of the country?
In those days, having a flashlight in your home was considered an extremely precious item.
Nowadays, flashlights don't use rechargeable ones, but rather batteries, so they're used with great care and are carefully stored away unless absolutely necessary.
They're all just for show.
Having learned this much, Shi Moyun knew that the mobile phone that had stirred his emotions was indeed a good thing. However, just as Xiao Fan had said, before that, they needed to solve the most pressing electricity problem for everyone in their daily lives...
