When buying a signal jammer, the shielding range of the signal jammer is what many customers want to know. Can the shielding range of the signal jammer be fixed? Naturally not.
The signal jammer scans from the low-end frequency of the channel to the high-end at a speed during operation. This scanning speed can constitute garbled interference in the message signal received by the mobile phone, causing the mobile phone to fail to detect the normal microwave signal data announced from the base station. In the plan, the mobile phone cannot establish a connection with the base station to achieve the purpose of shielding the mobile phone signal.
To put it simply, the frequency announced by the mobile phone signal jammer disturbs the mobile phone to receive the frequency of the base station. The jammer and the base station are destined to be a competitive connection. If the transmission power of the signal jammer is less than the channel that the base station transmits to the mobile phone in the environment at that time Power, then the jammer will not be able to shield, only the power of the signal jammer is greater than the power delivered by the base station to the mobile phone in order to effectively shield. Therefore, any shielding device used in different signal environments will show different shielding intervals, and mobile, China Unicom and telecommunications will be different, because the base station density, base station location and base station power built by these three operators can not be the same of.
In other words, how many meters can be shielded by a mobile phone signal jammer 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-scale transmission towers built on the ground, but also buildings. The signal expansion antenna on the top and the signal expansion and spreading made in some buildings), another important factor is obstacles, 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 wood board or glass material, the attenuation after penetration is relatively small.
So next time, a customer will say how many meters apart the shielding should be. Ask about the distance between the base stations in the environment, and then whether it is used indoors or outdoors, whether it needs to go through walls, etc. Customers can contact us Guanyu Electronics to learn about the use of signal jammers. Only by understanding these can they better choose a suitable signal jammer for customers.
