The influence is becoming more and more prominent. In prisons, detention centers, and other places of supervision, mobile communication tools, such as cell phones, are expressly prohibited, not only to prisoners but also to supervisors.

Some prisoners call, send text messages, obtain information, threaten witnesses through the illegal smuggling of mobile phones, and even form gangs to escape from prison. To this end, the installation of wifi jammer-blocking systems in prisons and other prison premises is imminent.

It is generally recommended that a base station is not required within 200 meters or 300 meters of the surveillance area where the wifi signal jammer is installed. If there is a base station, it is necessary to consider the impact of strong signals on the base station.
