When buying signal jammer, the shielding range of signal shielding is what many customers want to know. Is the shielding range of the signal shielding device fixed? Naturally not.
During operation, the signal screening machine scans from the low-end frequency to the high-end frequency of the channel at a speed that can cause garbled interference to the message signal received by the mobile phone. As a result, the mobile phone cannot detect the normal microwave signal data announced by the base station, and the mobile phone cannot be planned. Establish a connection with the base station to achieve the purpose of screening mobile phone signals.
The frequency declared by the mobile phone signal jammer prevents the mobile phone from receiving the frequency of the base station, and the jammer and the base station are in a competitive relationship. If the transmission power of the signal shader is less than the channel power sent from the base station to the mobile phone in the environment at that time, the shader cannot cover, and it cannot be effectively shielded if it is only greater than the power sent from the base station to the mobile phone. Therefore, any shielding used in different signal environments will show different shielding intervals, with different movement, connectivity, and telecommunications. The base station density, base station location, and base station power built by these three operators are different.
In other words, how many meters can be shielded by a mobile phone's signal jammer is not only related to its own transmission power, but also related to the spacing of the base stations in the use environment (a base station is not only a large transmission tower built on the ground, but also a signal on the roof. Amplify the antenna and signal amplification in some buildings. Another important factor is obstacles. If it is a metal material, it will be directly cut off. If it is a solid wall of reinforced concrete, it will not be attenuated by 10 times after penetration. If it is a wooden board , The attenuation after the glass is transmitted may be very small.
Therefore, this time the customer said how many meters should be shielded, so he asked whether the base stations in the environment are far apart, whether they are used indoors or outdoors, and do not need to penetrate walls. Guests can contact our Guanyu Electronics to know how to use the signal shield. If you know this, you can use a better method to select the appropriate signal blocker for the customer.
