When buying a wifi jammer, the shielding range of a wifi signal jammer is a point that many customers want to know. Is the shielding range of the signal jammer fixed? Naturally not.
The scanning speed of the wifi signal blocker can cause garbled interference in the received message signal of the mobile phone, so that the mobile phone cannot detect the normal microwave signal data announced from the base station, and the mobile phone cannot establish a connection with the base station in the plan to achieve the purpose of shielding the mobile phone signal.
To put it simply, the frequency announced by the wifi signal jammer disturbs the frequency of the hand receiving the base station. The jammer and the base station are destined to be a competitive connection. If the channel power is higher, then the blocker cannot block it. Only the power of the wifi signal blocker is greater than the power delivered by the base station to the mobile phone or other electronic devices, so that it can effectively block. Therefore, any shielding device will show different shielding intervals when used in different signal environments, and China Mobile, China Unicom and China Telecom will be different, because the base station density, base station orientation and base station power built by these three operators cannot be the same of.
That is to say, how many meters a wifi signal blocker can block is not only related to its own transmission power, but also related to the distance between the base stations in the use environment (base stations are not only limited to large transmission towers built on the ground, but also The signal expansion antenna on the top and the signal expansion and distribution in some buildings), another important factor is the obstacle, if it is a metal material, it will be blocked directly; if it is a solid wall of reinforced concrete, it will be less attenuated after penetration. 10 times; if it is a wooden board or a glass material, the attenuation after penetration is relatively small.
