The effective shielding distance of the mobile phone jammer is always the most concerned by customers! Some customers feel that the shielding effect is very good when they use it for a long time, and even the shielding distance exceeds the expected shielding distance. Using a shielding device is not enough to shield a room of 100 square meters. Why do you have these contrasting experiences? What are the key factors that affect the shielding distance of mobile phone jammers?
Generally, before buying a mobile phone jammer, when conducting pre-sales consultation with the manufacturer, the technical staff of the manufacturer will focus on reminding a key factor: the need to pay close attention to the location and distance of the mobile phone base station near the use site. Because the distance from the mobile phone base station will directly affect the final shielding distance of the mobile phone jammer at this use site. If there is a mobile phone base station within 200 meters or nearby, the manufacturer will directly inform that such a site environment is not suitable for installing mobile phone jammers.
The distance of the base station is one of the key factors, and the orientation of the base station must also be paid attention to. For example: even if there is a mobile phone base station at a relatively short distance near some use sites, if you stand in the window of the room and look towards the direction of the base station, you cannot directly observe the base station. There are other buildings in the middle. The building acts as a blocking effect, which will have a certain signal attenuation effect on the signal of the base station. In this case, using a mobile phone jammer may obtain a better shielding effect.
However, let’s change to another assumption of the environment: for example, standing in the window of the room and looking at the base station in the distance, even if the base station is more than 500 meters away, but because the base station can be directly observed visually, if the directional antenna on the base station is just right The front is facing the local area. Since there is no obstruction in the middle to attenuate the signal, if you turn on the mobile phone jammer in such a scene, you may find that the effective shielding distance is still very short.
