Signal Jammer

 There are many occasions in daily life, such as schools, examination rooms, conference rooms, prisons, etc., it is very inappropriate to use mobile phones. At this time, in addition to confiscating mobile phones in advance, signal jammer can be used to block the mobile phone signals within the range of specific occasions, wifi signal, gps signal to shield, without mobile phone signal, Internet signal, we will not play mobile phone, this can achieve the expected effect.

Mobile communication has brought great convenience to our lives, but in some special occasions such as the examination room, it is necessary to avoid the occurrence of people using mobile phones to check, leak secrets, and carry out sabotage through the mobile communication network. At this time, it is necessary to use radio jammer. The method to partially destroy the communication in the designated area, the signal blocker came into being.

During the working process, the frequency jammer scans the low-end frequency of the previous channel to the high-end frequency at a certain speed. This scanning speed will cause garbled interference in the information signal received by the mobile phone, and the mobile phone cannot detect normal data from the base station, resulting in failure to establish a connection with the base station. The phenomenon presented by the mobile phone is a paging network. The mobile phone has no signal and no service .

Signal jammers is a regulation device for mobile phones and PHS developed for the purpose of raising awareness and maintaining a safe and comfortable space for mobile phone users who do not follow good manners.The frequency jammer that we sell, is a device that jams 3G / 4G mobile phones, spy cameras, GPS, Lojack, VHF / UHF, 2.4GHz charged waves, etc. and makes them inoperable. It was supposed to be used in facilities where mobile phone calls and ringtones are annoying.

A signal jammer is a device that interferes with reception between an antenna and a wirelessly connected device (VHF, UHF, GSM, 3G, 4G, 5G, Wi-Fi, GPS). Developed for the military and law enforcement, the devices were originally designed to deal with threats such as cellphone-triggered explosives and hostage-taking. To block telecommunications, these jammers create a kind of signal traffic jam that blocks all communications. Like a radio silence bubble, users cannot send or receive any data, calls or text messages while within range of a signal blocker. These jamming devices overload mobile devices by transmitting signals at the same frequency and high enough power so that the two signals collide and cancel each other out.
