The more powerful the jammer is to block external communication

The smartphone is a communication tool. However, in some special places, mobile phones cannot be used in places such as test sites and libraries. The mobile jammer is here. There are many such products on the market. You can choose according to different locations. There are some technical requirements to meet the quality of the product. Currently, communication technology is also developing. The requirements for the function of the deterrent device are higher.

Recently, I heard a communication synonym, for example, a 5g jammer must block a 5g signal. Useful for security and confidentiality. The product quality requirements are very strict. Meet the current domestic high-tech technical requirements. The shielding effect of the product is good. You can use some complicated situations. It does not affect the surrounding residents. You can increase customer satisfaction. Normal product operation requires technical support.

As the name implies, the service interruption device has the function of preventing the mobile phone from external communication. It sends electromagnetic waves at the same frequency as the communication signal of a smartphone. This makes it impossible to distinguish between wifi jammer and useful radio waves. You can achieve the purpose of prohibiting the use of the phone. The jammer is mainly used when performing important tests. The jammer is usually turned off after the exam. Generally, all secondary schools restrict students from using mobile phones in school.

Many classrooms are equipped with cameras. There is a box with a width of 30 cm and a height of about 50 cm. In addition, the word “radio signal jammer” is written. During the graduate exam, CET exam and other unified exams, the test laboratory is installing gps jammers on the test site to establish a standardized laboratory. With the completion of the test center, the test site will prevent fraud through full-time signal detection, tracking and restriction.
