Soldiers, you are fast!

Wu Jie immediately contacted the Foreign Intelligence Agency and asked them to provide some information.

In any military power, military and civilian networks are separated.

Although they are both mobile network communication technologies, there are great differences between the two.

In order to meet the needs of a large number of users, high speed and large capacity, the civil network continues to adopt the latest technology, from 2G, 3G to 4G, the network speed is getting faster and faster.

However, in different places and at different times, it is easy to lose connection and slow network speed, especially in places with few base stations and many mobile phones, which is easy to get stuck to death.

In order to ensure that in times of war, it has strong reliability and resistance to destruction, and in order to be able to transmit data in a timely and effective manner, so that the war will not start, but it will not even be connected to the Internet, so that orders and intelligence cannot be transmitted.

Therefore, the military generally chooses very mature communication technology, and at the same time focuses on secrecy and anti-interference, which generally lags behind the civilian network generation.

Like nowadays, the 4G intelligent world has been very popular, as long as the traffic is enough, people can video entertainment, video chat, but data security is more worrying, many people are often prone to receive spam text messages sent by pseudo base stations.

Although the military network is still in the 3G era, it has technologies such as spread spectrum, frequency hopping, directional communication, power control, and waveform encryption, which can ensure the stability, security and anti-interference of data transmitted by the military network.

And in terms of technical details, the difference is also significant.

The military network uses a data link to achieve any point-to-point docking, and the system is simple.

It is equivalent to a warship that can directly exchange data with fighters through a data link, without having to build base stations and data centers.

In order to achieve stable communication at different distances, many communication equipment with different working frequencies will be equipped.

Within a range of tens of kilometers, C-Ku wave, millimeter wave, C-band and other frequencies can be used, although they cannot use the ionosphere for over-the-horizon sky wave communication, but the transmission of data is fast, can reach a speed of several megabits per second.

In the range of hundreds of kilometers, the HF frequency is used, which can form a good reflection with the ionosphere, the ground and the water surface, so as to obtain a large transmission distance without being affected by the curvature of the earth, but the speed is less than one trillion per second.

In order to achieve communication over distances of several thousand kilometers, either communication satellites are used for data relay, or only a few bytes per second of long wavelength or very long wave.

Therefore, in order to ensure that data communication can be achieved at various distances, whether it is a warship or a warplane, they can find that they have a lot of antennas.

In particular, warships are densely packed with tactical communication antennas, satellite communication antennas, VHF antennas, HF high-frequency antennas, and ......

And those tanks, infantry vehicles, etc., which are very close to each other and will not be particularly far apart, have fewer antennas.

This also reflects the fact that military networks are dominated by team communication.

For example, an aircraft carrier battle group can communicate with each other within a few hundred kilometers of its various types of equipment.

Cross-class, cross-unit, cross-equipment, long-range ......

Then the data is transmitted through a special communication satellite.

It is not because a warship sinks or a fighter plane explodes, and the entire communications network collapses.

......

The civil network is a centralized tree-like structure, and the structural system is extremely complex and huge.

A mobile phone exchanges data through the base station, and many base stations are connected to the management server of the data center with a communication line, and the data center is equipped with a variety of servers such as 2G/3G/4G that support various communication protocols.

Because of this, when the 4G signal is not good, the smartphone will automatically switch to 3G, or even 2G.

When you go to the barren mountains and mountains where there is no base station, or the basement or deep mountain canyon that is seriously blocked, the mobile phone will directly have no signal, and if the server is idle and out of operation, the entire network will not work.

......

So visible.

Compared with military networks, civilian networks seem to be technologically advanced and faster, but in fact, their stability and reliability are not as good as those of military networks.

With Wu Jie's technical strength, it is easy to invade the civil network data center of any country.

Like the civilian network built by the US imperialists, their server network architecture and security defense system have long been no secret to Wu Jie, and it is not difficult to invade and destroy data and cause the network to be deactivated.

It's just that......

The collapse of the civilian network will have a very bad impact on the operation of society.

The inability to access the internet, make and receive phone calls, and send and receive text messages can have a huge impact on all industries.

Nowadays, buses, subways, and ...... on the road There are bowheads everywhere.

Smartphones have been integrated into people's lives, chasing dramas, playing games, trading stocks, chatting, ......

If there is suddenly no network, you can't call an online car, you can't ride a shared bicycle, you can't order takeaway, you can't buy and sell stocks, you can't turn over bank accounts, and many companies can't operate normally......

Such a collapse does not need to last long to be enough to plunge a highly information-based country, socio-economic into chaos.

The more developed the country, the more important the cyber security.

And Lao Tan obviously knows that attacking the civilian network is too fierce and too destructive.

And this military network ...... It's too difficult.

......

It's about two o'clock in the morning.

Wu Jie downloaded the materials provided by the Foreign Intelligence Bureau one after another.

Military networks are relatively independent and closed, and I have not been in contact with them, so of course I don't know about them.

And these confidential materials were also obtained through various investigations.

For example, in some major military exercises, why would a hostile country send some electronic reconnaissance planes, spy ships, and the like to go around the exercise area?

Why do military powers launch electronic reconnaissance satellites to conduct uninterrupted reconnaissance in outer space?

The purpose is simple, it is to collect electronic electromagnetic signals.

Because any radar, any communication equipment, as long as it works, then it will generate a signal.

Through reconnaissance, it is necessary to grasp the working frequency of the enemy's radar and communications equipment, the characteristics of frequency conversion and frequency hopping, and so on.

Once a war starts, electronic warfare planes and fighters can be dispatched to attach electronic warfare pods to carry out corresponding electronic jamming, electromagnetic suppression, and even anti-radiation missiles to carry out destructive attacks.

Therefore, this is also why, once there are planes or ships of other countries in the exercise, the exercise will be suspended, or some core equipment will be urgently shut down, for fear of leaking electronic electromagnetic signals.

If the opponent enters the exercise area, then it is necessary to arrange fighter planes or warships to monitor and drive the opponent away.

That's why.

Only then will we often see the news that the joint military exercises formed by US imperialism and many small brother countries are huge in scale and equipped with a large number of personnel, and Russia will always arrange for large reconnaissance planes to go around and join in the fun, and then they will be expelled by fighter planes 'closely'.

So......

The information obtained by Wu Jie is a hard-won treasure of the Foreign Intelligence Bureau, but it may not be usable.

After all, the use of core equipment is all about caution.

Like phased array radar, if people don't turn on and use it, how can they detect and record?

Like the confidential satellite communication data link, there is not much communication all year round, how can the signal be intercepted?

But......

It is good to have this information, at least Wu Jie will no longer be ignorant of the military network of US imperialism.

And as the world hegemon, the strongest military power in the world!

Dominate the world and dominate the world.

The strength and sophistication of US imperialism's military cyber technology are indeed the highest in the world.

There are many communication data links, in addition to the commonly used link16/22 in the sea, land and air, the Navy also has a special CEC, and even stealth fighters have special MADL and IFDL, and are equipped with S-TADIL satellite communication data links for ultra-long-distance communication.

In addition they give strategic bombers, attack nuclear submarines, intercontinental missiles...... These countries also have special long-wave communications and satellite communications.

In short, there are many variety, technical variety, and encryption of all kinds.

It's not hard to want to interfere.

Because radio frequencies have a range, from low frequency to high frequency, from microwave to long wave.

A large electronic warfare plane was borrowed to detect the frequency band in which the enemy's electronic equipment was operating, and a large number of clutter signals were emitted in this frequency band to disrupt the enemy's communications.

But does this kind of interference make sense?

It's like other people are talking to each other, chattering and scolding on the side, which doesn't have a substantial hurtful effect.

What Wu Jie wants is invasion rather than interference!

It's a cold knife, not a trick on the sidelines.

It's just that......

After studying for more than an hour, I couldn't find a good way.

The difficulty coefficient is off the charts!

The military network of US imperialism is a typical private network, and the equipment connected to the network also has its own key system.

Just like on a civilian network, every computer surfing the Internet has a fixed IP address.

It's just that this key system will be updated regularly or irregularly, and identity verification will also be carried out.

When communicating with each other, they will identify friend and foe as if they were 'code', and those who can't match the key are enemies.

This method is to prevent the enemy from using its own communications equipment to achieve the purpose of 'listening and surveillance' when fighter planes are shot down and equipment is looted during wartime.

This kind of 'private network dedicated' level of secrecy is more difficult to be invaded than the higher-end of the Northern Fox organization.

The network of the Beihu organization is still based on the civilian Internet.

Even so, Wu Jie infiltrated their branch in Xiangjiang that time and successfully invaded through a dedicated server.

Today, the military network of US imperialism is more high-end and more secretive.

There is no communication equipment dedicated to them, no key system...... How the hell is this going to be invaded?

Could it be that he flew to Yuben overnight and secretly infiltrated the garrison base of the US imperialists?

Nima!

Isn't this looking for death?

......

The time came at three o'clock.

Wu Jie looked at the information and kept thinking about how to act.

And Tang Xiao on the side couldn't support his sleepiness anymore.

"No, no, it's really interlaced like a mountain, I really can't understand, you think about it slowly, I'll sleep for a while!"

Tang Xiao couldn't bear it anymore, gave Wu Jie a goodnight kiss, and lay down to sleep.

Wu Jie closed his laptop and slowly lay down.

With his hands behind his head, he stared at the ceiling in a daze.

Conventional means are no longer working.

But the brother system is possessed, and there are countless good things in the system mall.

Pity......

With the urine of the system, the more advanced and powerful, the more expensive the price.

Wu Jie fell in love with a space fighter.

Sci-fi in shape, powerful, able to freely shuttle between heaven and earth, and hit any target in the world in half an hour......

All the radars in the world are blind, and anti-aircraft missiles cannot catch up at all, and they cannot hit at all.

With such space fighters, the world hegemon is a fart!

It's just that......

The price is impressive!

4.8 billion power points!

Is this going to hollow out my brother all at once?

The seventh prize task is about to be completed, and it is one step away from five billion energy points.

In order to pretend to be forced to slap the US imperialist in the face, he spent 4.8 billion energy points to exchange for a space fighter?

It's not a good deal!

But the successive bullying and suppression really made my brother unable to swallow this evil breath.

Anyway, it has been in the limelight recently, and the growth rate of energy points is good, so Wu Jie decided to take 100 million energy points out to 'squander'.

After intelligent screening, the system recommends an unmanned reconnaissance attack aircraft priced at 90 million energy points.

Originally, it was heavily equipped on interstellar warships for long-distance infiltration and reconnaissance of unfamiliar planets and star fields.

The main task is to analyze, detect, perceive the environment, but it is also equipped with weapons that allow it to carry out defensive attacks.

Although in a high-level civilization, this kind of unmanned reconnaissance attack aircraft is not worth mentioning, a small-scale interstellar war will consume hundreds or thousands of aircraft.

But in a low-level civilization like the human race on Earth, it is already an invincible and powerful existence, abusing the enemy with invisible divine weapons.

For the first order, not only did I get a 20% discount, but I also got a console and two electronic pulse bombs.

Everything is satisfied, but the problem is ......

Why can't such a big killer be temporarily redeemed?

The drone and the console are added together, and at least one room can be installed.

Doesn't my brother have to find a hidden place and hide them for secret use?

Suddenly, Wu Jie thought of a good place......
