Chapter 576

"It doesn't seem as easy as we thought." Eric said: "I met Simon here before and saw his highness Gustav. Now this guy is tied with C4 and installed with electronic detonator. I noticed that it's not an ordinary bomb vest. Simon is proficient in blasting technology. I'm not sure I can dismantle it."

"Not necessarily." Lei Ming pointed to the singer and said, "we also have bomb disposal experts."

The singer himself was born as an engineer and worked in the minefield for two years. After that, he went to colleges and universities to study this major.

In unit 3, he is also a blasting expert and bomb disposal expert.

"As long as we can kill the person with the detonator, our people can definitely dismantle his bomb device," Lei Ming said with confidence.

"Now the most troublesome thing is not this problem." Qin Fei said: "the castle is in a mess. Who is human? Who is ghost? We don't know at all. Reston is dead. How many bodyguards did he send to participate in tonight's security? We can't kill people when we see them, but if we can't distinguish the enemy, we will die if we encounter them."

"What you said reminds me." Lei Ming said, "let's analyze. Now the police on the island basically won't have people on our side, so the remaining hard to distinguish are the bodyguards of GMT company. As long as we get their list, we can check it."

"How to get the list? How to check?" the old fish smiled. "Do you think you're on a formal mission now? Do you think you have intelligence support? We've been cut off from communication, and it's a problem to exchange information with each other. What should we do?"

After listening to the old fish, everyone couldn't help being silent.

Indeed, it's too passive now.

One of them is that it is difficult to distinguish between the enemy and ourselves. In addition, communication is cut off. Even tactical cooperation also needs communication support. Otherwise, the small units can only be crowded together and cannot act separately. The biggest disadvantage of being unable to act separately is that they are easy to be used in one pot and cannot carry out effective tactical cooperation.

Even for indoor CQB operations, according to tactical principles, it is impossible to squeeze more than a dozen people into a unit to act together in such a large castle, let alone with a protected VIP Charlotte.

But if Charlotte is separated, they are afraid that something will happen in the end. They can't know each other, resulting in no way to support.

"I have a way, maybe it can be used temporarily, maybe it can break through their communication interference temporarily." Yuri scanned the people with sneaky eyes and said cautiously, "but I don't know how good the effect is. I can't guarantee to replace communication, but at least it can be better than now."

"What way?" Qin Fei suddenly realized that as a top hacker, Yuri is not only familiar with network technology, but must have a certain involvement in all communication and electronic technologies.

The singer heard Yuri mention that he can break through communication interference. As a part-time correspondent in the third team, although he is not as skilled in electronic technology as Yuri, he also knows a little about ordinary technology.

"What can you do?" he suddenly became interested and came up to Yuri.

Yuri said, "you all have mobile phones with you, don't you?"

Everyone nodded.

"You turn on Bluetooth," he said, taking out his laptop, "and then pair it with my computer link. In my D disk folder, there is a software called 'blackbox', which I wrote myself. Download it to your mobile phone and install it."

Everyone quickly took out their mobile phones, entered the D disk of the notebook according to Yuri, downloaded the software blackbox and installed it.

"After installation, you plug the box of the agent's earphone into the socket of your mobile phone," Yuri said, demonstrating himself.

The singer suddenly understood and asked in some poor English, "do you want to use Bluetooth powerclass1 technology for interference breakthrough!?"

"Smart!" Yuri smiled and praised the singer and asked, "are you a messenger?"

"HMM." the singer scratched his head with embarrassment. Speaking of professional proficiency, he really couldn't compare with the big Russian boy in front of him. "I'm just a part-time Messenger, and my main responsibility is a Raider."

"What Bluetooth powerclass1 technology?" Qin Fei couldn't help asking.

"So..." Yuri thought while tapping the keyboard on his laptop: "powerclass1 is a Bluetooth technology. Generally speaking, the Bluetooth technology used on mobile phones is generally powerclass2. The coverage area of powerclass1 can reach 100 meters at most, and powerclass2 can only be 20 meters at most."

"Originally, the small black box with your agent's headset linked on your waist is a mobile terminal receiver, and the chip in it has the function of powerclass1. However, this small black box links to the communication platform on the police's communication vehicle, which has been occupied by grave diggers. They cut off our communication support, so even if our headset is not available Interference will also fail. "

"All I do is turn my laptop into a platform, and then activate the receiver on your waist through your mobile phone, so that you can contact within 100 meters."

"Bluetooth signal will not be disturbed?" Qin Fei still has doubts.

"Bluetooth works in the frequency band of 2400-2483.5mhz, which is in the same frequency band as most wireless LANs. Although its signal attenuation is large, the probability of interference is not great, because Bluetooth has a frequency hopping technology, which can take up to 79 frequency conversions according to whether there is a conflict in this frequency band."

Yuri said confidently, "this is a castle. There are many walls. After passing through the wall, the Bluetooth signal will weaken, but my blackbox software has optimized the Bluetooth call quality and signal, and it should be kept within 80 meters."

Qin Fei thought, 80 meters is better than nothing.

"It seems that we still have to find a way to restore communication. Using Bluetooth is not a way. It can only be an expedient measure."

"Yes, if the other party finds out that we are using Bluetooth, if they have communication experts as powerful as me, they can still interfere with or even block our Bluetooth signal," Yuri said.

"Fuck me!" the old fish couldn't help patting Yuri on the shoulder. "Your boy is powerful. He seems to know everything and everything!"

Hearing the old fish praising himself, Yuri was embarrassed: "in fact, the original software is not me. It's from your country Z. it's a red guest in country Z who has a good relationship with me on the dark network. He made the software. It's said that it was specially used for cheating in other people's examination room at first. I think it's very interesting. I took it to study it and made some changes myself..."

He smiled at the old fish: "you should thank your fellow hacker."

When they heard the speech, they immediately lost their laughter.

Yuri's statement seems true. There are many sophisticated cheating methods in domestic examination rooms, so jamming cars will be placed around the examination room every year to interfere with wireless signals to avoid cheating.

But I didn't expect that someone invented this kind of thing.

After finishing everything, Yuri said to all humanitarians, "you can try it now and see if it's easy to use."

Qin Fei flicked the agent's headset twice. The old fish nodded and thumbed up: "no problem!"
