Howler Blocking Cell Phone
Many customers called and said that I needed a Howler Blocking Cell Phone that can shield a radius of 50 meters, an interval of 500 meters, and a radius of 1 km, and that it needs to be shielded from the three networks of China Mobile, China Unicom and China Telecom. Is there a problem with the customer's request? No problem, and specific interval requirements are also given, but can it be completed? The answer is that it is more difficult to achieve. Why is it more difficult to achieve? Aren’t the parameters of cell phone jammer marked with their own shielding interval, can’t it be done by placing a few more units according to this interval? In fact, the customer is not wrong, but they do not know the mobile phone signal jammer. The shielding plan is not a fixed value, how to understand it. The mobile phone signal jammer scans the low-end frequency of the channel to the high-end at a certain speed during the operation. This scanning speed can cause garbled interference in the received message signal of the mobile phone, so that the mobile phone cannot detect the normal microwave signal announced from the base station. Data, within a certain plan, make the mobile phone unable to establish a connection with the base station to achieve the purpose of shielding the mobile phone signal.
To put it simply Howler Blocking Cell Phone The announced frequency disturbs the frequency of the mobile phone to receive the base station. The mobile phone signal jammer and the base station are destined to be a competitive connection. If the transmission power of the mobile phone signal jammer is less than the channel transmitted by the base station to the mobile phone in the environment at that time Power, then the mobile phone signal jammer can not be shielded, as long as the power of the signal jammer is greater than the power delivered to the mobile phone by the base station, so that it can be effectively shielded. Therefore, any mobile phone signal jammer 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 are impossible. Are the same. That is to say, how many meters a mobile phone signal jammer can block is not only related to its own transmission power, but also to the distance between the base stations in the use environment (base stations are not 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.
