In the past few months, we have noticed an increasing demand for mobile phone jammers from teachers and many school principals. For schools, cell phone jammer are very cheap and have limited range, which can be very beneficial. In this way, the “restricted area” can also be well controlled and will not affect passers-by or neighbors. The “Mobile Free Zone” is still in class or in school. I often hear the argument that no cell phone operator has ever asked if they can still send cell phone bundles to private houses, offices or schools.
As mobile phone jammers play an increasingly important role, the military will naturally become more interested in it. Duke said: “Compared with the same period last year, the military’s demand for mobile phone jamming incident testing has increased.” “It has increased further in 2019, partly because of anti-UAS [drone] activities. And they are now in Michigan. States, mobile phone interference that did not previously exist in places such as Wisconsin and Dakota will increase the authenticity of any form of military training. “As a result, more and more mobile jammer shielding tests, more and more satellite navigation aircraft and More and more pilots use GPS only. This is a feedback loop and continuously increases the risk that one of the missed and closed beeps will end in disaster.
