The shielding effect of the cell phone blockers during use is not static and is affected by many factors. This article will explore these factors in detail to help readers better understand and use the cell phone blockers.
| Signal strength | 1. Base station signal strength. The main function of the cell phone blocker is to interfere with the communication between the mobile phone and the base station. Therefore, the strength of the base station signal directly affects the shielding effect. If the base station signal is very strong, the jammer needs to send out a stronger interference signal to cover the base station signal and achieve the shielding effect. On the contrary, if the base station signal is weak, the work of the jammer is relatively easy and it is easy to achieve signal shielding. |
| 2. Mobile phone reception signal strength.The strength of the mobile phone reception signal will also affect the shielding effect. Different mobile phones have different antenna designs and reception capabilities. |
Transmission power of the jammer
1. Transmission power size
The greater the transmission power of the jammer device, the stronger its interference signal and the better the shielding effect. However, excessive transmission power will bring electromagnetic radiation safety problems, so the transmission power of the signal jammer needs to be adjusted within a safe range. Generally, the transmission power design of the jammer is to maximize the interference effect without affecting human health.
2. Adjustability
Some high-end cell phone jammers have adjustable transmission power. Users can adjust the power of the jammer according to actual needs to achieve the best shielding effect while avoiding unnecessary electromagnetic interference.
Shielding range and coverage area
1. Shielding range
The shielding range of the signal jammer refers to the area where it can effectively interfere with mobile phone signals. Generally speaking, the larger the shielding range and the wider the coverage area, the better the shielding effect. The size of the shielding range depends on the design and transmission power of the jammer device.
2. Physical obstacles
Physical obstacles such as walls, ceilings, floors, etc. have a significant impact on the shielding effect. During the propagation process, the signal will be reflected, refracted and attenuated by these obstacles, thereby affecting the shielding effect. Especially in buildings with multiple walls and multi-story structures, the effect of the jammer will be greatly limited.
Environmental factors
- Electromagnetic environment:The operation of the jammer is affected by the surrounding electromagnetic environment. If there are a large number of other electromagnetic devices around, such as Wi-Fi routers, radio equipment, etc., it will affect the interference signal of the jammer, thereby weakening the shielding effect.
- Weather conditions:Although mobile phone signals are mainly transmitted through electromagnetic waves and are not directly affected by weather, extreme weather such as storms and lightning may affect the stability of base station signals, thereby indirectly affecting the shielding effect.
Coverage of shielding frequency bands
1. Multi-band shielding
Modern communication technology uses a wide variety of frequency bands, including 2G, 3G, 4G, 5G and Wi-Fi bands. An effective jammer needs to be able to cover all these frequency bands. If the jammer cannot cover certain frequency bands, the corresponding communication signals cannot be shielded, affecting the overall shielding effect.
2. Dynamic adjustment
Some advanced jammers can dynamically adjust the shielding frequency bands and make real-time adjustments according to the surrounding environment and needs to ensure the best shielding effect. This technology can effectively cope with complex communication needs in different environments.
The shielding effect of cell phone blockers is affected by many factors, including base station signal strength, jammer transmission power, physical obstacles, electromagnetic environment, weather conditions, and coverage of shielding frequency bands. Understanding these factors will help you use the cell phone signal jammer more effectively and ensure the best shielding effect in different environments.
