Free Ad Blocker For Cell Phone Is Related To The Environment

Francisco Richard 2022/05/01

Simply speaking, the frequency announced by the mobile phone signal jammer disturbs the frequency of the mobile phone to receive the base station. The jammer and the base station are destined to be a competitive connection. If the transmit power of Free Ad Blocker For Cell Phone is less than the channel power delivered by the base station to the mobile phone in the environment at that time, Then the mobile phone jammer can't shield it. Only the power of the signal jammer is greater than the power delivered by the base station to the mobile phone so that it can be effectively shielded. Therefore, any cell phone jammer used in different signal environments will show different shielding intervals, 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. . That is to say, how many meters the shield can shield is not only related to its own transmission power, but also related to the distance between the base stations in the use environment (the base stations are not limited to large transmission towers built on the ground, but also on the roof of the building. 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 attenuate at least 10 times after penetration. ; If it is a wooden board or a glass material, the attenuation after penetration is relatively small.
