To curb the development of mobile phone jammers, we need to start from the source
In order to effectively curb the phenomenon of random sales and use of mobile phone jammers, the only way to manage them is from the source, with the cooperation of confidentiality, industry and commerce, quality supervision, and public security departments, and strict control from production and sales channels.
Recently, some readers reported to the Xinjiang reporter station of this newspaper that the mobile phone jammer device "cell phone jammer" (also called mobile phone signal jammer), which is strictly controlled by relevant state departments, has been blocked in the electronic market on Zhongshan Road, Urumqi. Some vendors blatantly sold at the counter.
Recently, the reporter conducted an investigation. In an electronic market on Zhongshan Road in Urumqi, a metal box with three antennas placed in a vendor's counter attracted the attention of reporters. This metal box is a "cell phone signal jammer".
The vendor told reporters that this instrument was 260 yuan, and that he really wanted to buy the instrument and negotiate the price. Afterwards, he took out the cell phone jammer from the counter, and the reporter found that the device had no text logo. "Where is this produced? Why is it not a single word, wouldn't it be a "three-no" product?" the reporter asked.
"There is no quality problem. I have instructions." The vendor said, but did not show the instructions to reporters. He told reporters that the coverage of this mobile phone jammer is 7 to 8 meters. After turning on the instrument, the signal of the mobile phone in the coverage area will quickly disappear. The reporter offered to experiment first, and the vendor readily agreed.
Subsequently, the reporter took out the mobile phone and put it on the counter, and pressed the button on the mobile phone jammer. Sure enough, after a while, the reporter's cell phone signal was gone and he could no longer make calls. The vendor proudly told reporters that he also has a more powerful "mobile phone signal jammer" that can interfere with the GPS satellite positioning system on the car. "When the instrument is turned on, the GPS satellite positioning on the car fails." He said that drivers of long-distance buses like to buy this product. The reporter saw that there is almost no difference in appearance between this instrument and the "mobile phone signal jammer" except for two antennas.
At the counter of another vendor, the reporter found that there were three different sizes of "cell phone jammers" on sale. The vendor told reporters that the prices of these three instruments are all over 200 yuan, but the scope of coverage is different. The reporter noticed that these three instruments also did not have any text marks. When the reporter asked the vendor about the manufacturer of these products, he replied: "I don't know."
During the investigation, the reporter also found a "mobile phone signal jammer" with more powerful functions and a coverage area of several hundred meters away. According to the vendor who sold the device, the price of the device is 900 yuan, and the vendor can provide one-month after-sales service, and there is also no text mark on the mobile phone jammer.
