Signal jammers should belong to special equipment

Yesterday, the Morning News reported that a BMW from a car rental agency in Wuhan was driven to Shanghai by a tenant, and was almost dismantled and sold. Fortunately, the owner of the car rental agency followed them all the way and finally retrieved the BMW from a repair shop in this city (see the A5 version of the yesterday morning report for details) . In fact, in order to prevent the rented vehicle from going or returning, the car rental agency installed 4 GPS positioning devices in the hidden location of the vehicle. I did not expect that the road would be one foot high, but the magical Power would be a small signal. Jammer.

  In accordance with relevant national regulations, the development, production and use of radio jammer equipment without legal procedures are illegal. Where did the aforementioned signal jammer come from? The reporter visited the electronic market yesterday and found that merchants completely ignored relevant regulations and openly sold signal jammer. Some merchants also sold them through the Internet, and anyone could buy them.

Yesterday, the reporter came to Yizhixin Automobile Service Company at No. 80, Lane 820, Jindu Road again, and found that the company’s sign had been removed and the door was closed tightly, but through the small door that was opened occasionally on the side, it could be seen that there were still employees working inside. There are also two cars parked. When the reporter asked in the name of repairing a car, a man said that there was something in the company and he would not be able to pick up work temporarily.

   The reporter then contacted Mr. Wei in Wuhan and Mr. Zhu in Yiwu who had found the missing car. Both have returned to their respective dealerships. After obtaining the consent of the police, Mr. Zhu drove the BMW back. Mr. Wei's BMW still needs to stay in Shanghai, awaiting further investigation of the case. Yesterday, both of them contacted the local police and the Shanghai police to inquire about the progress of the case, and the reply was that the two renters are still not caught.

   Yesterday, the reporter interviewed several car rental companies in Shanghai. Regarding the "robbing" of the vehicles in two rental car dealers in other places, the staff all said that they have paid attention to relevant reports and the topic is also being discussed in the circle. In fact, the other party used a core tool-signal jammer, "this thing is hard to guard against, it is the most hated thing in our business."

  Is there any review during the car rental process, and is there any threshold restriction on the car rental person? In this regard, Mr. Li, the marketing director of a car rental company, said that he has actually done a lot of work on “security”, such as verifying the identity of the renter. This verification is connected to the public security information system, including transportation and UnionPay systems, to further confirm Whether the renter’s identity background meets the car rental requirements. Another way to ensure that rented vehicles can be monitored at all times is to install GPS positioning devices. In addition, the car rental company will perform data analysis during the driving of the vehicle. When there are suspicious signs such as driving to other provinces, it will promptly confirm with the user, including on-site surveys, etc. If problems are found, they will promptly report to the police. In order to prevent the GPS positioning device from being dismantled, sufficient effort will be made in the number and concealment during installation, but what I did not expect is that the scammer used a new trick-signal jammer this time.

   Without any proof, anyone can buy

   A staff member of a car rental company told reporters that signal jammers cannot be bought or sold casually, but they can be bought casually on the market now, so some criminals have a chance to take advantage of it. Yesterday, the reporter visited the electronic market.

   In the electronic market at No. 500 Qiujiang Road, there are "information jammers" for sale in multiple shops on the first and second floors, and some shops also post advertisements on the walls. The reporter pretended to be a buyer to communicate with the merchant, and the clerk recommended two products of different Power . Among them, one is only the size of a cigarette case for use in the car, and the asking price is 160 yuan; the other is a silver-white metal box with 7 antennas, which can be used in a 200 square meter area at 560 yuan. The manuals of the two instruments are in foreign languages, and there is no text mark on the products.

   The reporter asked to experiment first, and the clerk readily agreed. Afterwards, the reporter put the mobile phone on the counter, and the clerk turned on an instrument. After pressing a red button, the indicator light turned on, indicating that the instrument started working. After a while, the mobile phone could not receive any signal and could not make calls.

  The clerk also said that there are more Powerful GPS satellite positioning devices that can interfere with cars.

   "Are you not afraid of the law enforcement agencies to investigate this?" the reporter asked. The clerk replied: "Nobody cares, we have been selling for many years."

   After going around several shops, I found that the signal jammers sold were basically similar. The owner did not shy away from its role, and did not ask the reporter about the specific purpose of purchasing the equipment. When the reporter asked about the manufacturers of these instruments, most of the merchants Wang Gu said to him, some said "These machines are unbranded", and some said "We are just sellers, and we don't know about the production." Or simply say "made in Shenzhen".

   Who is buying and using this instrument? During the interview, some shop assistants said that most of them were purchased by schools and companies. Some schools buy dozens of units once, and some companies purchase them to prevent employees from making calls during work. A clerk also said: “Gambling people buy a lot and put the equipment in the casino to prevent people from using their mobile phones to "get out of the thousands"."

   How about online sales? In both Alibaba and, you can find related products, and there are a wide variety of options available. In product promotion, they all emphasize Powerful functions and good shielding effects. However, no merchants have to provide relevant unit certificates or identity certificates for purchase.

   It is illegal to sell or buy without approval

  Can I buy and use the signal jammers on the market?

   The reporter consulted relevant information and found that as early as 2007, the State Security Bureau and the Ministry of Information Industry jointly issued the "Regulations on the Development, Production and Sales of Mobile Communication Jammers for Confidential Conferences." It requires that the sale of mobile communication jammers for confidential conferences should be strictly controlled. When authorized companies sell products to confidential units, they must be checked by the confidentiality work department above the city (prefecture) level or the confidentiality agencies of the central and state agencies. The approved "Confidential Conference Mobile Communication Jammer Purchase Review Record Form" is sold according to the approved product quantity and model, and detailed records are made. Authorized enterprises may not sell products to units and individuals without valid certificates, nor may they sell products in the form of consignment sales.

According to a staff member of the Shanghai Radio Administration, the use of signal jammers cannot be used at any time even if they have been approved by the relevant authorities, but must be "timed" (for example, only during confidential meetings) , "Fixed person" (specialized personnel), "fixed Power , range" (not allowed to increase the shielding range privately), etc.

   Who should supervise the signal jammers sold on the market? The staff member is not clear.

When the reporter contacted the industry and commerce department, the relevant staff explained that the signal jammer should be a special device rather than a common commodity. Just as the sales of medicines are under the management of the National Food and Drug Administration, it is still to be discussed what department the signal jammer is sold in the market.
