The Performance of Cell Phone Jammers and Their Ability to Penetrate Walls

Cell Phone Jammers are devices designed to emit wireless radio frequency signals specifically targeting mobile phone signals. These signals experience attenuation when encountering obstacles in their transmission path, and the degree of attenuation varies depending on the type of wall the Cell Phone Jammer faces. In some cases, different wall materials have different levels of attenuation on the Cell Phone Jammer. For example, walls made of lightweight steel keel gypsum board have less attenuation, as do materials like glass and wooden doors. Additionally, the signals emitted by Cell Phone Jammers can refract or reflect through open spaces such as doors and windows, as well as through walls, which can have some impact on the mobile signals behind the walls, creating an illusion of the jammer’s ability to penetrate walls. In reality, the wall-penetrating performance of Cell Phone Jammers is similar to that of home WiFi routers.

Factors Affecting Wall-Penetrating Ability:

The ability of a Cell Phone Jammer to penetrate walls is also influenced by the transmission power of its various frequency bands. Generally, the higher the transmission power, the stronger the penetration ability. This can be understood by comparing it to listening to sounds from the next room through a wall. If the sound from the next room is loud, it can be heard clearly, but if it is soft, it will hardly be audible. The wall-penetrating ability is also related to the frequency of the wireless signals emitted by the Cell Phone Jammer. As we know, lower frequency wireless signals have stronger diffraction capabilities, just like the radio stations we usually listen to. The signals transmitted by radio and television stations typically range from tens of megahertz to over one hundred megahertz, which are very low frequencies. A single transmission tower can cover over 100 kilometers. Lower frequency wireless signals have stronger penetration capabilities.

Considerations for Wall Installation:

When using a Cell Phone Jammer, if it can be determined that the wall is made of gypsum board or wood, the option of installing the jammer behind the wall can be considered. However, the wall-penetrating ability is still dependent on the transmission power of the jammer’s various frequency bands. As mentioned earlier, higher transmission power results in stronger penetration ability. Additionally, the wall-penetrating ability is also influenced by the frequency of the wireless signals emitted by the Cell Phone Jammer. Lower frequency signals have stronger diffraction capabilities. Therefore, when using a Cell Phone Jammer, if the wall material is confirmed to be gypsum board or wood, the option of installing the jammer behind the wall can be considered. However, if the wall is made of brick or concrete, it is not recommended to install the Cell Phone Jammer behind the wall.

Conclusion:

The performance of Cell Phone Jammers in penetrating walls is influenced by various factors such as the type of wall material, transmission power, and frequency of the wireless signals emitted. Understanding these factors can help users make informed decisions when installing Cell Phone Jammers. It is important to consider the specific requirements and characteristics of the environment in which the jammer will be used to ensure optimal performance.
