GPS signal jammer devices are currently used

The Russian sky army now has 3 jammers based on the Yel -22, but the first generation of "lumber" is not particularly large, the reason is very simple - Russia has only about 10 IL -22, and it is no longer produced.

In recent years, the number of websites offering “cell jammers” or similar devices designed to block communications and create a “quiet zone” in vehicles, schools, theaters, restaurants, and other places has increased substantially. While these devices are marketed under different names, such as signal blockers, GPS jammers, or text stoppers, they have the same purpose.

A wifi jammer is a blocking device of cell phones, which sends the blocking signals to towers from the same frequency range of the cell phones, the interference cause the cell phone to lose the signals from the station.

But the main problem is a Jammer cannot be detected. Your phone will remain in poor signal reception if a Jammer is active in the area. The Federal Communication Commission of the United States (FCC) has control over broadcasting public telecom services.

In ancient days, people usually worked on the day and went to bed early at night and enjoy the sweet dream. But as the mobile phone was invented, we play it both on the day and at night. Moreover, the problem caused by the mobile phone becomes much more obvious than before. Nowadays, we can avoid the misuse of cell phone with the high power cell phone signal jammer now.
