  Mobile phone jammers gps are mainly used in various places: schools, examination rooms, gas stations, libraries, prisons, conference rooms, courts, hospitals, governments, finance, public security, military areas and other places where the use of mobile phones is prohibited. In fact, the on the market can effectively scan equipment with a range of 600 meters. For example, the working radius of the jammer shield is about 20 meters. Its shielding radius can be adjusted and the coverage can reach about 30M². The mobile phone signal blocker in the examination room only shields the mobile phone signal and will not affect other electronic equipment. At present, the mobile phone signal jammer gps in the test room are between 100-300 yuan for low power, 500-1000 yuan for medium power, 1000-10000 yuan for high power, and some special customized versions are priced at higher. In short, you need to buy a mobile phone jammer according to your own needs.

  Every year in the examination season, many parties are gradually anxious to plan for the examination, and the invigilators will use various tricks to avoid new technology fraud. Among them, the special for the examination room is still an anti-blocker. However, Shijiazhuang Anshida, as a well-known manufacturer of signal shielding devices, reminds that there are various varieties and specifications of shielding devices. Before purchasing, the application party should determine its own requirements to prevent the actual shielding effect from being poor and causing safety accidents in the examination room. Also pay attention to the accuracy of the method of operation. First of all, I want to establish the application field. Most of the 88 used in the test field type are suitable for long-term work and are durable. The second is how big are we in the blocked area? For example, it is a one-hundred-square-meter house or a site of more than one thousand square meters. If the total area is large, the output power must be larger, and if the total area is small, the shielding output power can be adjusted. There is also what frequency band must be blocked, is China Mobile, China Unicom, Telecom, CDMA all blocked? Or only part of the frequency band must be blocked.

  In the 2021 college entrance examination, there are suddenly more discussions about whether is harming students' physical and mental health, and whether it affects students' normal thinking. The reason is that the blocker on the mobile phone will harm the normal thinking of people. Since then, reports that smartphone GPS jammers are harmful to the body have appeared in the newspapers one after another. Some news media reporters even said that the reporter felt close to 88 , "within 15 minutes, dizziness, stuttering, unable to concentrate logical thinking, chest tightness, nausea and vomiting, etc.". The parents of the students who hoped for their children to become talents were frowning at such information, and eagerly hoped that the authority would go out and make it clear. There are two key ways to shield data signals at this stage. One is physical digestion and absorption. Install wire meshes and boards outside the building to digest and absorb the radio waves of data signals, so that data signals cannot be received in the room. This kind of method is expensive and inconvenient to install, and is generally only used in physical laboratories with unique requirements. The other is to send radio waves to affect the data signal to achieve the purpose of shielding. Judging from reports in the news media, it seems that such devices that can transmit radio waves should be installed in the examination rooms for the high school and college entrance examinations across the country.

Currently, each of us has a mobile phone

  From previous 2G phones to now 3G and 4G phones, some people have even started using 5G phones. No matter what phone you're using, even high-end phones won't have a signal when the cell blocker is on. It is also understandable that cell phone signal blockers are the natural enemy of cell phone signals, but there are so many types of on the market that we don't know which one is better. Cell phone jammers gps are rarely used. The places that are often used at ordinary times may only be companies engaged in scientific research. There are also research and development departments on state secrets. The other is the military, where security and confidentiality-related places have set up cell phone jammers gps. It is better to have this brand in the signal jammer in hand. This brand is also sold at different prices. That's because their performance is different. Let's take a look at the prices of cell phone jammers gps.
