As a device used to block mobile phone signals, mobile phone signal jammers are widely applied in various scenarios. However, during the usage process, users may encounter some doubts and confusions. Next, we will provide detailed answers to these questions to help users better understand and use mobile phone signal jammers.
【 Signal Indicator Phenomenon 】
Why do some mobile phone signal indicators still show a signal when the mobile phone signal jammer is in operation? This is actually a misleading phenomenon. Under the effect of the jammer, although the mobile phone can no longer perform normal communication functions, the signal indicator may still show that there is a signal. When you try to make a call or send a text message, you will find that there is actually no signal available because the phone has been completely blocked by the jammer.
【Interfere with other devices】
Will mobile phone signal jammers interfere with the normal operation of other electronic devices? No. The electromagnetic signals emitted by mobile phone signal jammers are strictly limited within the working frequency band of mobile phones, and their function is only to block mobile communications. Moreover, this signal remains relatively stationary and will not cause interference to any electronic devices.
【 Impact on Health 】
Can mobile phone signal jammers cause harm to the human body and mobile phones? Users need not worry. The electromagnetic signal intensity emitted by the mobile phone signal jammer is very weak. After testing, this signal strength is far from sufficient to cause any harm to the human body. Meanwhile, a mobile phone signal jammer merely blocks the forward signal of the mobile phone, preventing it from communicating with the base station. Therefore, it does no harm to the mobile phone itself.
【Indoor and Outdoor Effects】
Is the effective shielding distance of a mobile phone signal jammer different when used indoors and outdoors? There are indeed differences. Under normal circumstances, the effective shielding distance of a mobile phone signal jammer indoors is approximately 30 to 40 meters. However, in outdoor open areas, its shielding distance can be extended to several hundred meters. It is worth noting that the actual shielding effect of the jammer can be affected by various environmental factors, including the distance from the base station and the specific location where it is installed. Therefore, when using a mobile phone signal jammer, these factors must be fully considered to ensure the best shielding effect and avoid shielding blind spots.
【 Effects on Different types of Mobile phones 】
Is the shielding effect of mobile phone signal jammers on GSM mobile phones and CDMA mobile phones the same? In fact, since CDMA mobile phones have significantly better anti-interference performance than GSM mobile phones, the effective shielding distance of mobile phone signal jammers for CDMA mobile phones is slightly shorter than that for GSM mobile phones, but this difference is not significant, approximately 2 to 4 meters. However, in certain circumstances, to ensure adequate shielding of CDMA mobile phones, it may be necessary to increase the deployment density of mobile phone signal jammers within the venue.
【 The Influence of a Hot Casing 】
During the continuous operation of the mobile phone signal jammer, its casing will become hot. Will this affect its long-term use? It is a normal phenomenon for the mobile phone signal jammer to get hot when it has been working for a long time, and this will not cause any damage to it. Our design ingeniously takes advantage of the excellent thermal conductivity of aluminum alloy thermal strips to assist the machine in heat dissipation and ensure its stable and long-term operation. Therefore, you can use it with confidence. The overheating of the phone case will not cause any damage to the phone signal jammer.
【Selection basis and occasion restrictions】
When choosing and using a mobile phone signal jammer, one must carefully consider its shielding range and effect. Since the functions of different models of mobile phone jammers vary, the selection must be based on actual needs. In addition, the power and application range of the mobile phone jammer are also important factors to be considered when making a choice. For instance, there are mobile phone jammers specially designed for meeting rooms, military units, prisons, examination rooms, gas stations and confidential places, etc. To ensure that the mobile phone jammer can perform at its best, it is essential to choose it based on the actual usage environment.
