With the widespread use of mobile phones, there has been a significant increase in the demand for full band frequency jammers for various purposes such as meetings and exams. As a result, full band frequency jammers have gained popularity in the market. However, many customers lack sufficient knowledge about these devices and often make the mistake of choosing high-power jammers without considering the potential risks. This article aims to highlight the importance of selecting the appropriate power level for full band frequency jammers to ensure effective and safe usage.
Understanding the Principle:
The principle behind full band frequency jammers is to emit interference signals across a wide range of frequencies, disrupting the uplink signals of mobile phones and effectively blocking their operation. As such, these devices act as signal transmitters and naturally emit radiation. Currently, full band frequency jammers have varying transmission power levels ranging from 1W to 100W. To put this into perspective, the maximum transmission power of a GSM mobile phone is 2W, while GSM macro base stations typically have transmission powers between 20W and 40W. For general exams and small-scale meetings, a full band frequency jammer with a transmission power of 2W to 10W is sufficient to achieve the desired results.
The Pitfalls of High-Power Jammers:
Unfortunately, many educational institutions and important meeting venues often prioritize high-power full band frequency jammers without considering the potential consequences. For instance, in a school with over 20 classrooms, each equipped with a full band frequency jammer with a transmission power of 50W, there is a risk of some jammers not being promptly turned off after exams. This can result in continuous emission for several weeks, posing a significant threat. In a particularly alarming incident at a primary school, a full band frequency jammer remained active for two weeks after an exam, emitting radiation continuously in a classroom filled with young students. This highlights the importance of responsible usage and the need to avoid blindly pursuing high-power jammers.
Recommendations for Safe Usage:
In light of the potential risks associated with high-power full band frequency jammers, it is crucial for organizations and institutions to consider the following recommendations:
- Avoid blindly selecting high-power jammers: For a single classroom, a full band frequency jammer with a transmission power of 2W is sufficient to achieve the desired shielding effect. It is unnecessary and potentially dangerous to opt for higher power levels.
- Ensure timely shutdown after usage: After completing the intended usage, it is essential to promptly turn off the full band frequency jammer to prevent continuous radiation emission.
- Choose products from reputable manufacturers: It is imperative to select full band frequency jammers produced by legitimate manufacturers. Non-standard manufacturers often prioritize enhanced shielding effects by increasing transmission power, which can lead to unnecessary risks.
In conclusion, the selection of the appropriate power level for full band frequency jammers is crucial to ensure effective and safe usage. Blindly pursuing high-power jammers can result in unintended consequences, including prolonged radiation emission. By following the recommendations provided and choosing products from reputable manufacturers, organizations and institutions can mitigate potential risks and ensure the responsible use of full band frequency jammers.
