GPS jammers cannot be bought and sold casually

A staff member of a car rental company told reporters that GPS jammers cannot be bought and sold casually, but they can be bought casually on the market now, which gives some criminals a chance. Yesterday, the reporter visited the electronic market.

In the electronic market at No. 500 Qiujiang Road, many shops on the first and second floors have "gps jammer" for sale, 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 a 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, and costs 560 yuan. The manuals of the two GPS jammers 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 a GPS jammer. 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 agency to investigate this?" the reporter asked. The clerk replied: "Nobody cares, we have been selling for many years."

After going around several shops, it was found that the GPS 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 GPS jammer? 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. They put the equipment in the casino to prevent people from using their mobile phones to "get out of money."

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.
