The Importance of Signal Jammers in Regulating Mobile Phone Usage in Public Places

With the increasing popularity of mobile phones, their usage has become more frequent and widespread. However, many people do not pay attention to the appropriate usage settings and use them freely in various places. This behavior disrupts the quiet and serious atmosphere in specific locations such as conference rooms, courtrooms, libraries, and schools. The noise generated by frequent mobile phone usage affects the normal functioning of these places. Merely relying on human intervention to enforce restrictions on mobile phone usage has proven to be ineffective. However, the solution can be as simple as using a full-band signal jammer, which effectively resolves the issue of improper mobile phone usage in conference rooms, prevents wastage of resources, and reduces costs.

The Role of Full-Band Signal Jammers:

The effectiveness of a full-band signal jammer in blocking mobile phone signals depends on the proximity of the local base station. In most cases, a conference room with an area of less than 200 square meters only requires one full-band signal jammer to perfectly block mobile phone signals. However, in certain conference rooms, it may be observed that while a full-band signal jammer can successfully block signals from China Telecom and China Unicom, it fails to block signals from China Mobile or the blocking distance is relatively short. The fundamental reason behind this phenomenon is that the signal strength of China Mobile’s mobile phone signals in these conference rooms is weaker compared to China Telecom and China Unicom, resulting in a better blocking effect. This is because the base stations of China Mobile are closer to the conference rooms compared to those of China Telecom and China Unicom. The relationship between full-band signal jammers and base stations is antagonistic. Both emit electromagnetic wave signals in the same frequency band, but the electromagnetic wave signals emitted by full-band signal jammers are intended to suppress signals from base stations. The transmission power of a single channel of a full-band signal jammer is generally between 2-3W, and it cannot suppress the signals if the base station signals are too strong. This leads to situations where a full-band signal jammer fails to block signals.

Addressing the Issue:

In cases where a full-band signal jammer can only block signals from China Telecom and China Unicom but fails to block signals from China Mobile or the blocking distance is insufficient, a solution is to increase the transmission power of the mobile module in the full-band signal jammer specifically designed for China Mobile. The SMa-818K90, a high-power full-band signal jammer, is produced by combining independent modules that can be used individually or combined. By adding the mobile module to the high-power full-band signal jammer, the issue of being unable to block signals from a specific mobile network operator can be resolved. This combination of a high-power full-band signal jammer and a low-power full-band signal jammer enables complete signal blocking.

Conclusion:

The increasing usage of mobile phones has led to a disregard for appropriate usage settings in public places, disrupting the quiet and serious atmosphere required in certain locations. The use of full-band signal jammers provides an effective solution to regulate mobile phone usage and prevent wastage of resources. However, in cases where a full-band signal jammer fails to block signals from a specific mobile network operator, the addition of a high-power module specifically designed for that operator can resolve the issue. By implementing these measures, the proper functioning of conference rooms and other similar locations can be ensured, promoting a more productive and focused environment.
