These places attach great importance to information protection and require a powerful power jammer. Portable cell phone jamming devices are commonly used in places such as business vehicles and library meeting rooms.

Recently, many people use smartphones, and people have the right to freedom of communication. Freedom of communication refers to the right of citizens to use letters, telegrams and telephones freely. However, in recent tests, there were cheating problems with mobile phones, and bank transfer fraud in financial institutions. In many movie viewing halls, you will often see the phone ring and hinder viewing. In order to prevent the inconvenience caused by ringtones such as smartphones and to ensure quietness in specific spaces, we accept the installation and operation of signal jammers.

Mobile phone jammers and other non-service equipment used to interfere with radio waves have attracted people’s attention. These devices make mobile phones unavailable in certain areas. When installing this device, care should be taken not to hinder the freedom of communication and to prevent problems caused by poor communication of the mobile phone. The two seem to directly conflict. Freedom to use mobile phones seems to be an important right for individuals, and the use of signal jammer can be linked to public welfare.

While enjoying the right to use freedom of communication, it is important not to disturb others. Using the mobile phone for the college entrance examination violates the regulations. We cannot guarantee the fairness of the exam, and you may harm the rights of others. Therefore, it is legal to install interference equipment to prevent cheating, which is an effective measure. In order to prevent the inconvenience caused by ringtones such as mobile phones in public places, it is necessary to consider installing such interference equipment.

There are many situations that bother other people. There are bad behaviors, such as cheating on a mobile phone at the test site, creating unfair results. In addition, sensitive information may leak in sensitive locations such as military bases and government agencies, and hospitals also need to provide patients with a tranquil environment.

This means that you can make and receive calls temporarily.Cut-off signal: Compatible with GPS / 3G / 4G / CDMA / GSM / DCS / PHS / Wi-Fi.

Effectively prevent signal transmission including GSM, CDMA, 3G, 4G, 5G, GPS, WIFI, etc. We cannot make or answer calls. In addition to improper use, it may also cause more problems.

Mobile phone calls operate in different frequency bands in different countries. Asia and other regions tend to use the GSM900 and 1800 frequency bands.
