Nanqian Province is too far away, and Bai Song has no way to reach it. According to Senior Brother Ren Hao, the probability of this case being purely coincidental is higher.

　　 Leave these things behind for a while, Bai Song checked the translation software, and slowly finished the translation, took the equipment to Cao Detachment, and roughly explained the company's situation and the state of the equipment.

　　 "Literally speaking, this thing does not have the function of eavesdropping, right?" Cao Detachment was relieved: "I will arrange for someone to study it later."

　　 "Okay, then Cao Detachment, I will continue to go out for interrogation tomorrow, is it okay?" Bai Song asked.

　　 "Go ahead."

　　 Cao Detachment finished speaking, and seeing Bai Song not moving, he was a little confused: "Why don't you leave?"

　　 "Um... Cao Detachment, can I apply for a car..." Bai Song prayed for his fuel tank. He is poor and short...

"Okay, use it, take it from the Wang team." After the Cao Detachment finished speaking, he continued: "But if you are nervous in the future, try not to occupy the bus. After all, if you go to interrogate this matter, I can't talk to other leaders. speak."

　　 "Thank you Cao Detachment!" Bai Song ran away happily.

　　 In another three or five days, the farther detention centers will be able to finish the run, and the rest will be about ten kilometers away. It doesn't hurt to use your own car.

　　 Back to the house, Bai Song first contacted Wang Liang.

　　Wang Liang took the high-speed rail and just arrived at the destination. He told Bai Song that the GPS coordinates are a bit troublesome, and he may have to wait for a while.

　　 This is not in a hurry. Bai Song knows that even if he knows the coordinate points, he will not go there for a while, and because other cars have taken away these suspected money goods, the coordinate points are not necessarily valid.

　　 Bai Song asked Wang Liang. If you have other inquiries and need to go to the local Public Security Bureau to investigate relevant information, please help check the car by the way.

　　There should not be many cars like this, looking at the entire Shonan Province. I just don't know whether the local query system supports the search method of direct query of car models.

　　 After chatting with Wang Liang for a while, Bai Song realized that the WeChat group chat in the class was full of joy.

　　 Yesterday, I talked about some wonderful cases in the police station, and the students were very interested. Of the 30 to 40 classmates in Bai Song’s class, a small half went to the police station, and most of the rest were in government agencies. There were also some who did not work as a police officer or postgraduate entrance exams such as Zheng Chaopei (resigned) and Zhou Xuan. very high.

　　 At this stage, most of the serious violent crimes such as homicides can be effectively cracked down, but many cases, such as telecommunications fraud, have been difficult to satisfy the people.

　　The crime detection rate is not high, especially for small fraud. Once fake IDs, fake usernames and the like are used, the cost of crime is not high.

　　 When Bai Song was in the third team, Wang Liang had a lot of telecommunications fraud cases, and many of them couldn't be solved in the end. It was okay that they could be transferred to Wang Liang. Many small scams in the game, some prices are as low as a few cents or even a few cents of RMB!

This is really not a joke. For example, a game that was launched in China in 2008, Dungeon and Warriors, had a low-level picture called Zombie King, and brought 3000 game coins (according to the price at the time, it was about two cents). Many people After collecting the money and ran away, of course this is also a fraud, and someone really called the police.

　　 There are too many cases, too many fake information, fake IP, VPN...In short, it is very troublesome. For this kind of fraud cases, the best way is to combine attacks and preventions. On the one hand, they crack down and on the other hand, they promote prevention.

　　 When everyone talked here, they started to appeal to each other.

　　 Do something together, do more publicity, if one more person sees it, one less person may be fooled.

　　 I have to say that the number of people is still very powerful, and some anti-fraud knowledge has been organized, and everyone has shared it through their own circle of friends and social accounts, and the live broadcast industry V. Zhou Xuan has become an important figure in this event.

　　 The most common scams are collected:

　　 WeChat and QQ directly send QR codes to borrow money (popularized at the end of 2013, and this technology has just appeared now);

　　Part-time online;

　　Investment with an annual interest of 8% or more;

　　 order fraud...

　　...

　　 This is a good thing, Bai Song suddenly thought that his certain blog seems to have hundreds of thousands of fans!

　　 closed the notification, Bai Song re-entered his account, reposted what everyone wrote, and then closed a blog.

　　...

　　 After get off work in the afternoon, Cao Detachment called Bai Song again and asked Bai Song to go there.

　　 It seems that the condition of the equipment has fallen. Bai Song ran all the way to the office of Cao Detachment.

　　 "No storage equipment?" Bai Song heard the Cao Detachment talk about it, and was very puzzled: "What is this thing?"

"The technical department said it was a repeater, and the transmitting frequency band was ultrashort wave. The specific meaning was not mentioned in the report." Cao Detachment handed a short report to Bai Song: "You college students, these are all high-achieving students. What do I mean by that."

　　 All the reports came out? It's something that the leaders are concerned about, but it's different...Bai Song took the brief report and explained to Cao Detachment after reading it: "Our common wi-fi is ultra-high frequency radio waves~www.mtlnovel. com~ The wavelength is in the centimeter level, and the transmission distance is short. This thing is a very high frequency radio wave. The wavelength is long. In the range of 1-10 meters, the transmission distance is long. Simply put, our common FM broadcast is this Meter wave; the common AM broadcast is medium wave, and the wavelength is one hundred times that of FM."

　　 "Do you mean that this thing transmits FM radio?" Cao Detachment understood. Everyone has used semiconductors.

"No, the power is far worse. This is a repeater. The black radio station in Tianbei District before was not a high-tech, but it was superior in power. This thing is an adaptable repeater that can be used for those Black radio transmits signals for control and playback.

　　 The black radio station cannot directly connect to the mobile phone, but the content on the mobile phone can be played directly through this repeater, and there is no good clue even if we find it because there is no storage device. "

"This is not an ordinary criminal suspect." Cao Detachment nodded: "Since the secret issue of our team is not involved, it's okay. But we can't take it lightly. The leaders of the team know about this. Let's go. Recently, you are not. Do you want to go out and take the transcript? I will arrange a car for you. You take your drone and turn around the tops of the high-rise buildings and some unmanned factories nearby. If you find any more, tell me in time. "

　　 "Okay, Cao Detachment, I'll go around more these days." Bai Song replied seriously.

　　 "Well, here's a key for you, you take it." Cao Detachment said and took out a car key: "You can use this car as you like these two weeks. If it is not available, hand it over to the king team."

　　 "Okay, thank you Cao Detachment!" Bai Song was overjoyed.
