Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 497 CDMA, not afraid of electronic jammers!

In the United States, freedom of the press has always been advocated, which means that the scandals of top officials can be exposed, such as the Lewinsky scandal. On the surface, everyone seems to be equal.

In reality... who would dare say a bad word about squid?

Of course, that was a special case. Now, when reporters learned through special channels that the military was going to test civilian mobile phone networks, they rushed to the scene!

Qualcomm's New York office was completely blocked.

Seeing this situation, Evan Jacob and Martin Cooper exchanged a glance. It was clear that they couldn't avoid it. Since they couldn't avoid it, they might as well brag first.

"Martin, you go ahead. After all, you are the father of the mobile phone."

"This CDMA technology wasn't developed by me..."

"You have to do it, hurry up!"

And so Martin Cooper was pushed forward.

"Ladies and gentlemen, please come to the conference room. Our father of the mobile phone will introduce our mobile phone project to you!"

hula la...

A group of people walked into the conference room and looked at Martin Cooper pacing back and forth on the podium.

Click, click!
The reporters' cameras were constantly clicking, and Martin Cooper felt like he was going to go blind.

"Ladies and gentlemen, the most advanced mobile phone communication technology currently is CDMA. In New York, AT&T is responsible for network construction. In our New York City, to provide the best communication service, a total of eight base stations have been built. Qualcomm has launched a brand new mobile phone to support this mobile phone network..."

"Where did this base station technology come from?"

"I'm about to conduct an anti-interference test. Does this mean that this mobile network is suitable for military use?"

With everyone bombarding him with questions, Martin Cooper realized he couldn't answer them anymore.

So, Evan Jacob had no choice but to step forward: "Gentlemen, military matters involve classified information, so I can't say too much. However, I can give a brief introduction: our mobile phone network has very strong anti-jamming capabilities. In half an hour, the military's electronic jamming equipment will be coming over. At that time, you can all test the quality of mobile calls..."

"But we don't have any test equipment!"

"We at Qualcomm will provide one to each person."

Wow…

Watching the reporters disappear quickly with their phones, Evan Jacob was both amused and exasperated. What did this mean? Were these guys just here to get free mobile phones?
These media figures seem to be people you can't afford to offend!

The reporters were scattered throughout New York, their heads gazing at the sky.

Amidst the roar, a Navy EA-6B electronic warfare aircraft flew over.

"ALQ-126B has locked onto the target frequency band!"

"Full-power interference!"

Countless electromagnetic waves were released through five ALQ-99 jamming pods, enough to cover ten bands. Each of them had a maximum power of twenty kilowatts, yet they couldn't even interfere with a small civilian signal.

In that instant, the entire city of New York became an electromagnetic island.

The television screen was filled with static, the radio was crackling, and the walkie-talkie completely stopped working...

The reporters picked up their phones and made calls.

"Hey, honey, I might get off work really late tonight..."

The call quality is excellent and the call is clear!

At this time, many military experts were also conducting tests with mobile phones. Despite the strong electromagnetic interference, the calls could be made normally, the text messaging function was unaffected, and even the data connection could be turned on to access a dedicated network!
The EA-6B electronic warfare aircraft circled New York three times before flying away; otherwise, it would have been criticized!

Qualcomm division.

“It seems our system has withstood the test,” Martin Cooper said, still shaken.

"That's right, this CDMA technology is truly advanced; it can even withstand electromagnetic interference!" Evan Jacob exclaimed with admiration. "Now, our mobile phones will definitely sell even better!"

Sure enough, the whole of America was stunned after the television report that evening.

It's unbelievable that civilian telephones have such good call quality, even unafraid of military electronic jamming devices!
We should buy one of these mobile phones!
When will this network be available in my city?

Everyone was full of anticipation.

As soon as a base station is available, I'll buy one right away!
The United States has the highest consumer spending power in the world, which is why some people in later generations dared to impose tariffs. It's the largest consumer market. However, he forgot that they are also the largest money-printing country. They can buy things with the money they print themselves, which is already taking advantage of the whole world.

As for spending money extravagantly and not being able to pay it back... well, these days creditors are the boss.

Pentagon.

"Our electronic jammers can't even interfere with this kind of mobile communication!" Countless people looked grim.

what does this mean?
Their enemies, once they establish this mobile phone network, will be able to operate without fear of American electromagnetic interference! How will the Americans then utilize their electronic technology advantage in warfare?

“We should completely stop the promotion of this technology!” one person said.

"Hmph, so you think you can stop others from progressing just because you're behind? How can you possibly ban everything! At most, we'll ban European countries. Once Moscow gets that information, they'll definitely give us their full support! Then we won't have advanced mobile phone networks, but we'll have an adversary, you idiot!"

The group was clearly divided into two factions.

Those who want to stop this technological development are a minority. After all, during the Cold War, most Americans were very ambitious. If they were technologically backward, they had to quickly improve their technology!
“I believe our electromagnetic interference technology is outdated! We should develop more advanced electronic jamming machines,” Swift said.

In science fiction, full-band, high-blocking electromagnetic interference sounds impressive, but in reality, it's very difficult to operate and requires too much power!

Needless to say, electronic jamming machines can't even interfere with warships! The only thing that can do that is the sun! Only electromagnetic interference from something as powerful as the sun can disrupt all radio equipment on Earth!

The technology used by electronic jammers is to suppress the target's frequency band by installing a receiver antenna at the tail of the machine. Then, the receiver compares the frequency band with the target's frequency band, selects a suitable jamming pattern, and releases it from its own jamming antenna.

The central processing unit, or CPU, is the hub of this interference system.

“Currently, our jammer’s data sampling rate is too low, not even as fast as CDMA’s. As a result, when we release jamming electromagnetic waves, we cannot suppress the original electromagnetic waves, leading to electromagnetic interference failure,” the engineer present said.

"Then let's upgrade the jammer's performance!"

"Gentlemen, the electronic jammer on the EA-6B is currently the most advanced one that we can develop domestically!" The engineer shook his head: "With our technology, this is the best we can do."

"What do you mean by that? That our technology is still inferior to that of the East?"

"Yes."

The atmosphere in the meeting room became tense again.

The military's electronic jamming capabilities are inferior to those of the East? How can they suppress the East in the future?

"Ahem, everyone, let's talk about electronic interference later. At least the current experiments prove that the Easterners are capable of creating a first-class data link. The foundation for our arsenal ship project is already in place."

With strong transmission capabilities and high anti-interference capabilities, it means that the biggest data transmission problem that has plagued arsenal ships can now be solved!
Since this problem can be solved, then the arsenal ship project should be launched!

Weinberg nodded: "That's right, Burda, you're right. The arsenal ship project can continue, and the ten million has already been allocated."

"Ten million is not enough. Northwestern Polytechnical University needs fifty million to help develop the technology. Moreover, they also need us to open up the weapon interface."

"what?"

Now, some people are unhappy again.

"How can this be!"

"That's right, the weapon interfaces are our core secrets. We absolutely cannot provide them with these. They need to provide us with all the technology!"

"Gentlemen, we've already seen how advanced Eastern technology is. If civilian mobile phones are this powerful, their military versions will only be more so. Do you think they'll provide us with that technology?" Burda said. "This technology is advantageous to us; we must develop it as quickly as possible..."

“Bulda, how about this?” Weinberg said, “For data transmission, we will purchase equipment from the East, but we will handle the data provision on the Aegis warships and the processing of the data received by the arsenal ships.”

Weinberger still knows how to compromise.

Burda nodded: "Okay, I'll go talk to the Easterners." In this way, the Eastern equipment will essentially provide a transmission channel. Everyone just needs to agree on the data interfaces on both sides of the channel. The secrets of the American arms dealers will not need to be revealed to the Easterners.

Eastward, Northwestern Polytechnical University.

During this time, Burda was like a revolving lantern, constantly traveling between the two countries. Even Qin Liang admired him a little. This guy was really dedicated and pure!

“Mr. Burda, what you say makes sense, but... five hundred launch tubes, the quantitative change has already caused a qualitative change, so... do you think that with the United States’ technological level, we can handle the other subsystems? Putting aside everything else, the interchange alone is a huge problem.”

The American MK41 vertical launch system is touted as having incredible capabilities, with its multi-purpose functionality being the main focus of the hype!
It can be matched with all kinds of missiles, including Standard, Sea Sparrow, Tomahawk, Astok, etc., and can even have four missiles in one cell.

However, this isn't something you can switch over easily.

Replacing a missile requires replacing all six of the associated printed circuit boards and the interface equipment of the storage and transportation container, which is extremely complicated. As a result, while Aegis warships boast that they can be mixed and matched, in reality, each launch tube fires a fixed type of missile.

What about arsenal ships?

The launched missiles must be agile!

How did they solve it?

The swapping is just a minor issue; controlling these 500-plus missiles requires complex circuitry! Given the Americans' electronics technology, they would simply scale it up, for example, by transplanting ten sets of control circuits from the Burke-class destroyers, dividing them into ten groups, and controlling them separately.

If we want to launch quickly, interference between the different groups... will likely become a problem.

Qin Liang smiled and said, "Once we move into detailed research and development, there will be a whole host of technical problems to solve. You'll have to come to us for help then. So... right now you can just take the data channel and we can develop it for you for 30 million US dollars. However, I still suggest you give us 45 million. That way, if you encounter any technical problems later, we can help you solve them for free without charging you any extra."

“Okay.” Burda nodded. He also realized that for the arsenal ship to succeed, it had to use Eastern technology!
"Also, regarding the electronic jamming machine..."

"I'm sorry, Northwestern Polytechnical University has not yet ventured into this field."

The Americans want advanced electronic jamming machines? Of course we can't give them that!

After seeing Bulda off again, Qin Baomin asked, "Liangzi, when do you think this old general will come again?"

"Next time it will probably take longer. After all, they only come to us when they encounter problems they can't solve... Dad, I shouldn't have anything to do during this time..."

dong dong!

There was a knock on the door.

"President Qin, Principal Qin, we just received some new information. The South Koreans want to come and inspect our Northwestern Polytechnical University."

South Koreans!
Early 1980s!

Therefore, by the mid-1980s, especially after the 1988 Seoul Olympics, and finally in 1992, formal diplomatic relations were established.

just now……

"We can't make this decision on our own; we need to consult with the capital," Qin Liang said immediately.

It's good for us, but... many leaders' ideas are not easy to change, we have to ask for their opinions first!
The message came back quickly.

"What was the response from above?"

"Let us make our own decision. Whatever choice Northwestern Polytechnical University makes, the higher authorities will fully support us."

This……

Qin Liang was speechless. You're making me do an experiment.

"Let's invite them to visit our new campus of Northwestern Polytechnical University first, and then see what they have to say."

To be honest, Qin Liang didn't have a good impression of North Korea. On the contrary, after establishing diplomatic relations with South Korea in later generations, our economic development actually benefited from their influence.

Of course, South Korea also has its downsides. They actually tried to subvert our aesthetics with effeminate men. Fortunately, we withstood the test. On the parade ground, those iron-willed warriors are the ones who truly represent us.

Northwestern Polytechnical University, new campus.

A group of South Koreans got off the bus and looked at the modern campus with complicated expressions.

They walk with a powerful stride and stand ramrod straight; even in suits and ties, you can tell they are from a military background.

"Principal Qin, where is your aviation department located?"

"The aeronautics department is located on the old campus."

"And your navigation system..."

"It's also on the old campus."

The South Koreans were a bit embarrassed. They had originally wanted to visit these places, but they didn't expect... they had come to the wrong place?

"However, graduate students conduct research and development here, and some scientific research equipment is also here. For example, we have a supersonic wind tunnel on our campus. Would you like to take a look?"

"well!"

After the visit, the South Koreans were all deeply impressed.

In the afternoon, everyone gathered in the meeting room.

"President Qin, the research and development capabilities of Northwestern Polytechnical University truly impress us. We in South Korea don't have a research university like this. Could you…?"

The air force officer leading the team, Park Hee-do, spoke first.

"Mr. Park, please speak."

"Could you help us... design an airplane?"

To this day, South Korea's aviation industry remains very weak, lacking any capacity for production, let alone research and development.

They first acquired production technology by introducing the F-16 fighter jet production line. In 94, the KF-16 made its maiden flight, which greatly excited South Korea. Then, in 97, they began to jointly develop the T-50 advanced trainer jet with Lockheed Martin. After that, they developed the KF-21 fighter jet, which they could also boast about to the world.

They haven't even brought in the F-16 production line yet! But they've set their sights on the booming Eastern aviation technology, so... they want to improve their aviation industry with Eastern help?
Qin Liang frowned: "If it's a civilian airliner, there's definitely no problem. But if it's a military aircraft... sorry, Northwestern Polytechnical University doesn't have the guts."

This is a way of reminding the other party.

You come here seeking help, but you have absolutely no sincerity whatsoever!
"Our South Korean airline is willing to purchase C919 and C929 passenger aircraft! As long as you agree, we will purchase twenty aircraft in the first batch!"

The other party has indeed shown sincerity!

Qin Liang shook his head: "That won't work either. I'm sorry, we really don't have the guts."

Thirty aircraft!

"Well... fighter jets are definitely out of the question. I wonder if you are aware that we have showcased a trainer aircraft?"

"Coach Ten?"

"That's right, it's that trainer aircraft used to train pilots. If you need it, we'll sell you the production blueprints for two hundred million US dollars. As for the parts, you can find them on the American market. If you also need our help to build a factory, then pay another three hundred million to five hundred million US dollars, and you can obtain the trainer aircraft production technology!"

Everyone was overjoyed.

South Korea is not short of money. After World War II, they also experienced rapid economic growth. Spending 500 million to acquire aircraft production capacity was well worth it!

Don't be fooled by the fact that it's a trainer aircraft; with its leading-edge extensions, blended wing-body design, and all-moving tail, it's a modern fighter jet in every sense!
Industry insiders say that this aircraft is comparable in strength to the F-16!

"However... we have one more condition."

"Please tell us. We can agree to any conditions."

“Sever all ties with those people across the ditch.”

What?
"Principal Qin, don't worry, we won't leak the technology of this aircraft to those people," Park Hee-do quickly said, realizing what was happening.

Qin Liang shook his head: "No, no, it's not just the aviation industry, it's a complete severance of ties. Only if you agree to this condition can we continue to cooperate, otherwise... please leave."

The arms trade is never just about selling weapons; how can you not even understand that?
