Mobile jammer shields emergency calls
The classroom is usually not very large, so it is recommended to use a mobile cell phone jammer. This is very easy to carry and use. You only need to press a button to open it. Of course, you don’t have to worry about emergency situations where someone needs to call you. Some devices can interfere with telephone signals. Essentially, it pretends to be a base station, not a base station. The problem with this is that it disables emergency calls. In theory, you can implement some methods to switch the phone to "silent mode" when it is placed in an unauthorized location (because the operator always knows the location of the phone). However, no one has proposed this as a product or standard, but it is not particularly difficult. You may have to pay because you are the owner of a movie theater or a restaurant.
Last month, we announced the ability to detect drone swarms. Assuming the same conditions, MyDefence is now announcing a group of drone cell phone jammers, which has been proven on Electric Storm. During the event, five drone operators attempted to conduct a coordinated drone attack. Using the PJ drone perfectjammer effectively eliminated the coordinated attack, and all drone operators lost control of the drone.
Armies around the world regularly conduct "electronic warfare", jamming everything from wireless communications and radar to satellite signals. However, as with all "real-time shooting" exercises, a threat alert is issued and an exclusion space is declared. In addition to the school order framework, Mr. Brown also emphasized that prohibiting the use of mobile phone jammers is also "good public health information for the family." Good for children. He warned his parents not to touch the screen for a long time, especially before he was seven years old. That is the guarantee of Macron's presidential election.
