As the most popular communication tool in modern society, mobile phone has a wide signal coverage. It is an important means of communication for the rescue team and the affected people.

In some specific cases, the mobile phone jammer may be considered as an application scenario for emergency rescue, and its potential applications include:

1. Control chaos:
At the beginning of an emergency, such as a terrorist attack or a mass incident, there may be chaos at the scene. Cell phone signals may be used to organize illegal activities or spread panic messages. In this case, it is possible to temporarily cut off the communication between these activities by using the mobile phone jammer, which will help the field control.

2. Protect key facilities:
When some key infrastructures are attacked or fail, it may be necessary to use jammers near the site to block communication in order to prevent further sabotage from being triggered remotely by mobile phones.

3. Avoid false positives:
At the disaster site, a large number of mobile phone communications may lead to network congestion and affect the communication quality of rescue teams. In this case, the limited use of jammers may help to reduce the network burden and ensure the smooth rescue communication.

However, even in emergency rescue, the use of mobile phone jammers must be very cautious and strictly follow laws, regulations and ethical principles. Ensure that there will be no negative impact on rescue operations and public interests. At the same time, we should seek safer and more legal technical means to support emergency rescue work.
