WiFi signal jammer is an electronic anti-mobile phone WiFi signal device. It can cover and hide the mobile phone signal from the transmission tower by sending a larger sound signal of the same frequency. By covering and suppressing the mobile phone signal, it covers a specific area. All phones in will be disabled or unavailable.
WiFi jammers are very useful in many public places where mobile phones are not welcome. Once we have a wifi jammer, when we don't want to hear the noise of a noisy mobile phone, we just turn on the jammer and all nearby phones cannot make or receive calls.
In fact, WiFi signal interference products have a wide range of applications and can be used everywhere where mobile phones are not welcomed. It can be used in military, gas station and government buildings with restrictions on mobile phones. In addition, it can be used in places where absolute silence is required, such as hospitals, conference rooms, concert halls, schools, libraries, examination rooms and churches.
