Signal Jammer

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.

Frequency Jammer

Basically, it's a radio frequency (RF) transmitter that, depending on the hardware, broadcasts radio signals in the same (or similar) frequency range for Wi-Fi, GSM, 4G, 5G communications. In general, most scramblers have a few meters less range. However, more powerful jammers can create an area the size of a football field. Those used by law enforcement can block areas up to 2 kilometers away from the device.

Low-power mobile phone signal shielding instrument is relatively common for indoor mobile phone signal shielding under normal circumstances. The high-power mobile phone signal jammers are basically used outdoors, and only a few are used indoors. The main reason is to use high-power mobile phone signal jammers indoors when the indoor area is relatively large and the environment is relatively transparent.
