All kinds of signal jamming devices have become part of life

In response to the netizens’ reactions, the reporter recently interviewed shi shishi, President Chen. President Chen confirmed the “installation of mobile signal jammers in the classroom”. According to its introduction, there are more than two thousand students, more than 40 classes. Due to the serious phenomenon of students playing mobile phones in the classroom, they have had a great impact on normal teaching activities, so they decided to install mobile signal jammers in each classroom. At present, most classes in the central high school have been installed. After these “GPS jammer” are enabled, cell phone signals are blocked in the classroom. But as soon as you get out of the classroom, the signal will be restored. For the “health impact” problem, Chen, a physics major, explained that there was no scientific common sense. On the one hand, the installed jammer is a qualified product, and its electromagnetic radiation is in accordance with the relevant national standards, and many schools and examination halls are already in use. On the other hand, from a physical point of view, the frequency of electromagnetic waves emitted by jammers is low, which will not affect the human body at all.

LMADIS engagement procedure goes something like this: the RPS-42 detects the drone on radar, or alternately Skyview detects the back-and-forth radio signals between the drone operators and the drone itself. Next, the electro-optical/infrared camera is trained on the incoming drone to make a positive identification as friendly or hostile. If hostile, the Marines aim the MODi jammer at the drone and prevent the drone operators’ radio commands from reaching it. Gravity takes care of the rest.

Recently, netizen “mickey” reported to the reporter, the stone lion three middle and high central high school classroom in many classrooms recently installed “mobile phone signal jammer”. Internet users worry that the “jammer” will cause harm to the human body? In “shi shi SAN zhongzhi” post, the reporter saw, the netizen “the big bang” uploaded a classroom to install the cell phone jammer picture, at the same time also to whether affects the health to express the question. Its post attracted more than 20 replies and hundreds of visits. In the local BBS and community of shishi, there are also posts that reflect the installation of mobile signal jammers in the classroom. Netizens have different attitudes and some netizens are worried about the “health effects of radiation”, while some netizens believe it will help solve the phenomenon of “students playing mobile phones in class”.

The incident took place in the Strait of Hormuz, which connects the Gulf of Oman to the Persian Gulf. The 11th Marine Expeditionary Unit, embarked on the amphibious assault ship Boxer, parked a LMADIS jammer on the Boxer’s flight deck to provide a defense against Iranian UAVs known to operate in the area. The marines detected an Iranian unmanned aerial vehicle and jammed it when the drone closed to within 1,000 yards of the Boxer.
