The jammer can shield the 2G, 3G, 4G, 2.4G WiFi signal of the mobile phone. The test room signal jammer can not only shield the mobile phone text messages, but also cannot even make Internet calls. The signal jammer has a very wide range of use and can be used in the test room , Corporate conference rooms, gas stations, as well as prisons, troops, government agencies and other secret-related places.
What should I pay attention to when purchasing a signal jammer?
Mobile phone signal jammers used in examination rooms generally have more appearances with built-in antennas. First, they can play a beautiful role. Second, they will not create psychological pressure on candidates in the examination room. It is the most used instrument in standardized examination rooms and is controlled by machines. It is carried out under the standard safety of 4W per channel. Low power has no effect on people at all.
The mobile phone signal jammer used in the examination room is relatively low in use, the power of the equipment used is relatively small, and there are reasons such as cost budget. Therefore, the price of the jammer used in the examination room is generally about 500-1500. If you need to shield 5G signals If so, the price will be a little higher. The shielding device used in the conference room, if the scope of the shielded meeting room is large, the power of the shielding device used will naturally be a little larger, and the specific product can be recommended according to the requirements.
The mobile phone signal jammer scans from the low frequency band of the forward channel (the channel from the base station to the mobile phone) to the high frequency band at a certain speed during the working process, and forms interference when the mobile phone receives the message signal, so that the mobile phone cannot detect the slave base station The normal data sent, thus unable to establish a connection with the base station, showing no signal and no service state.
There are many companies that produce and sell mobile phone signal jammers on the market, and the quality and price are also uneven. It is recommended that when purchasing, it is recommended that you actually test the jammers according to the area of use and specific needs. By comparison, don't blindly pursue low prices, but choose a shield that suits you.
