Full band signal jammers, also known as cell phone signal blockers, are commonly used in secure meeting rooms, standardized examination halls, prisons, and other locations where the blocking of mobile phone signals is necessary. However, the effectiveness of these jammers can be influenced by various factors. This article aims to explore the factors that affect the shielding effectiveness of full band signal jammers.
Factors Affecting Shielding Effectiveness:
- Transmitting Power:
Full band signal jammers can be categorized into high-power, medium-power, and low-power machines. Generally, the larger the transmitting power, the greater the blocking distance. In areas with strong signals or places equipped with indoor amplifiers, high-power full band signal jammers are required to effectively block mobile phone signals. Low-power machines usually have less noticeable effects. Additionally, the usage environment, whether indoors or outdoors, can also affect the blocking distance of full band signal jammers. In most cases, the shielding effectiveness indoors is better than outdoors. Therefore, when selecting a full band signal jammer, a comprehensive analysis of the environmental area, signal strength, distance from base stations, and building structure should be conducted to recommend a suitable device to the customer.
The effectiveness of full band signal jammers in blocking mobile phone signals is influenced by several factors. The transmitting power of the jammer plays a crucial role, with higher power resulting in a greater blocking distance. Additionally, the usage environment, such as indoor or outdoor settings, can also affect the shielding effectiveness. When choosing a full band signal jammer, it is important to thoroughly analyze the environmental area, signal strength, distance from base stations, and building structure to recommend the most suitable device to the customer. By considering these factors, the desired level of signal blocking can be achieved in secure meeting rooms, standardized examination halls, prisons, and other sensitive locations.
