high power cell phone jammer desktop design
How to prevent unauthorized special places at gas stations, prisons and military bases? Maybe we can't do the general way, you know it's pointless. In prison, the prisoners were always given education, and even gave up the phone - no. Therefore, officials must take strong action to directly prohibit unauthorized calls. The cell phone jammer operates on these devices because the strongest action of the device is to block the call.


Cell phones are a common problem in prison: through E-mail, family visits are delivered via mail on baby diapers, smuggled in prison inmates... The prisoners seem to have a lot of options to get the phone, and the land cannot be changed. To get a cell phone, plan prisoners can attack gangs or coordinate external attacks. Cell phones interfere with prison guards to help maintain a safe internal environment.


The mobile jammer is fixed, the cover is about (20-100) M @-75dbm still depends on the signal strength of the given area, so as to calculate the indoor, many units should be the best result obstacle.


Mumbai's police have provided safe "manufacturing India", an ambitious project set up by prime minister Narendra Modi. Police will use mobile phone jammers, unmanned aerial vehicles (uavs) and integrated CCTV reported (BKC) in order to ensure a week of events will be held in class - korla Della complex, will be composed of several important guests and foreigners to participate.


The device outputs low-power radio signals or codes modulated radio waves. Some of the signals that are designed to jam the current signals, the same mobile phone and the frequency of the pager, cut the tower and the mobile terminal, and prevent the new transmission structure, and the other as a device that doesn't have the frequency to be in an electronic filter, to answer the phone, some jammer is designed to adapt to a different range of work frequencies, to jam the interference of 2G 3G 4G. Mobile GPS jammer are almost a professional jamming signal, including 2G 3G networks. Although they have cell phones, prisoners can't make and answer calls. Prison officials don't have to worry about being locked up, they can only turn off the phone from the outside.


We also use drones and portable jammers for quick response teams. Although there is no terrorist threat, because this is a place where foreigners go, all security measures should be taken. This will be a three-tier security event. More than 100 CCTV cameras will monitor the incident. "Said Deven Bharti, a joint commissioner for police law and order.


The rapid development of science and technology has made us a mobile communication tool. It goes without saying that thanks to cell phones, we can communicate with family and friends whenever possible. Mobile phones also bring us a lot of entertainment. Children and teenagers have a large number of mobile phone users, and students' lack of attention and lack will have a negative impact.
