how to choose suitable mobile phone frequency jammer

Interference between multiple systems: small devices in machine space, CDMA, GSM, DCS / PHS, 3G.4G systems, mobile jammers may transmit between signals with multiple interference bands, possibly between indicators High power, wide frequency band, intermodulation, etc.,The age of owning a smartphone is decreasing year by year. Elementary school students often play mobile games. Some people worry about the effects of electromagnetic waves generated by smartphones. We use mobile phones every day and feel it is impossible to prevent electromagnetic waves.

The recommended installation height is 1-2 meters. First make sure that the main body of the shielding cover is fully charged, then turn on the switch and start working. Turn on the indicator.wifi jammer installation instructions and methods.The protective cover is a maintenance-free device and requires no maintenance.When wiping the control surface of the jammer, do not use chemical solvents and avoid inhalation. If you want to use a WiFi interference device, store it in a dry, well-ventilated place to avoid prolonged exposure to salt spray and harmful gases.

Remove the shielding jammer from the box, and screw the antenna into the corresponding antenna board, otherwise it is invalid. The shielding cover is hung on the wall or the corresponding place.There are multiple ways to protect yourself. Simple and affordable is a device that can cut off the signal of a smart phone, a wireless jammer device for WiFi networks.It is normal for the Mobile Phone Frequency Jammer to not harm the machine after a long period of work. In design, we use aluminum alloy wire drawing machine to heat. Therefore, various signal interception equipment such as 3G / 4G jammers can ensure long-term stable work.
