Now our signal jammers are used in a wide range of places, mainly in meeting places that need to be kept secret such as party and government agencies, courts, detention centers, large, medium and small prisons, etc., college entrance examinations, 4-6, judicial and other standardized examination rooms. All are prohibited The place where the mobile phone is used.
So what are the functional and structural characteristics of our signal jammer?
1. The signal jammer is made of high-dispersion aluminum alloy shell, the working temperature is low, and the shielding effect is more stable. It has a built-in silent turbo fan with low working noise.
2. Its separate power adapter, signal jammer antenna external design, unified one end of the interface makes the appearance more beautiful and decent, and has an anti-loosening design, the antenna and the host have a marked working frequency band to facilitate one-to-one correspondence.
3. Now our signal jammer adopts foreign advanced chips and technology, slow-start circuit design, high integration, multi-channel segmented independent shielding technology, better effect, ultra-high frequency interference technology, only interferes with the downlink, not the base station.
Cell phone signal jammers are divided into omnidirectional and directional types according to the shape of the shield. The omnidirectional type is an olive shape, and the directional type is a fan shape, so the omnidirectional type is better than the directional type. Large shielding area;
The mobile phone signal jammer is to generate a certain electromagnetic wave to interfere with the downlink of its mobile signal. If the power of the jammer is greater than the power of the local mobile signal, then the mobile phone will have no signal. If the power of the jammer is less than the power of the local mobile signal, the mobile phone There will be a signal.
