The primary purpose of a mobile phone signal jammer is to disrupt or block the transmission of signals between mobile devices and cellular towers.
Mobile phone signal jammers are employed to disrupt mobile phone calls and network transmission within a specific vicinity. Typically, these devices find application at college entrance examination venues to deter certain students from surreptitiously carrying advanced electronic gadgets into the examination room for cheating purposes. However, it should be noted that the primary objective of a cell phone signal jammer extends beyond this particular scenario.
To guarantee the security of crucial locations and positions, numerous confidential establishments will deploy mobile phone signal jammers in select sensitive areas, adhering to pertinent management regulations and requirements. These jammers effectively disrupt the transmission and reception of mobile phone signals, including 2G, 3G, 4G, 5G, WiFi, Bluetooth, and other signals, within a specific range. Consequently, communication connections and data transmission become unattainable, effectively enforcing a mandatory ban.
Mobile phone signal jammers possess the capability to obstruct mobile phone signals. These devices are commonly employed in examination rooms to deter candidates from engaging in cheating activities. Due to their remarkable shielding effectiveness, mobile phone signal jammers have raised concerns among individuals regarding their potential impact on base station signals within the vicinity or surrounding communities.
A mobile phone signal blocker operates by emitting targeted signals to disrupt, obstruct, or impede the connection between a mobile phone and the base station. As a result, the mobile phone is unable to receive any signal or access network services. Additionally, the text messages transmitted and received by the mobile phone will be distorted, rendering the original content unrecognizable.
An installation plan for the outdoor signal jammer is being devised.
In order to install the signal jammer outdoors, it is crucial to implement waterproofing and lightning protection measures. It is generally advised to opt for a dedicated installation box designed specifically for signal jammers. This installation box is constructed using flame-retardant plastic and can be extended with additional meters on both sides. It features a window-type ventilation position to enhance heat dissipation. The antenna of the mobile phone jammer protrudes from the top of the box through a sealed hole using hot melt glue. At the bottom of the box, there are power input holes and diversion holes to prevent water accumulation.
The signal jammer's host is positioned at the top of the box, while the antenna protrudes from it. It is crucial for the antenna to extend out of the box to maintain the optimal shielding effect. As for the power adapter, it should be placed in the lower and middle section of the box.
It is imperative to implement lightning protection measures when installing the signal jammer (along with the installation box) outdoors, for instance, on the exterior wall of a building. This precaution becomes even more crucial in areas prone to thunderstorms. Extra attention should be given to ensure safety in such circumstances.
The installation of a lightning rod on the shield is the actual measure taken for lightning protection. In case a ready-made lightning rod is not available for purchase, one can create their own lightning rod using the following method.
You have the option to select 3-4 steel bars ranging from 5-10mm in diameter and 50cm in length. One end of each bar is sharpened to resemble a needle, while the other end is welded together to create a "Y" shape. The welded end is then connected to a steel bar with a diameter of 2-3mm. The ground, where the iron wire is protected by PVC pipes, is connected to one end of the iron wire. This iron wire is further connected to an iron strip. Typically, the iron strip measures around 50-100cm in length and 2-5cm in width, and is driven deep into the ground. In case iron strips are not readily available, you can substitute them with 10mm steel bars.
It is imperative to install the lightning rod at a height of 30-50cm above the antenna of the mobile phone signal jammer. To avoid any interference, it is crucial that the lightning rod, including the grounded steel wire, does not come into contact with either the mobile phone jammer or the installation box. The appropriate distance between them should be maintained.
