How to use the cell phone signal blocker to achieve the maximum effect? from dojammer's blog

In modern society, cell phone signal blockers are often used in large and medium-sized examination halls, and are also widely used in gas stations, financial institutions, hospitals and national defense areas. As long as there is a sign prohibiting the use of cell phones, there is generally a cell phone signal blocker. So how should you use the cell phone signal blocker? What is the basic principle of the cell phone signal blocker?

When using the cell phone signal blocker, select the area where the cell phone signal needs to be disconnected, and put the disconnector on the local desktop or wall. After the installation is successful, connect it, disconnect the power supply, and immediately turn on the main power switch. After the device is connected, press and hold the main power switch to disconnect the appliance and it can work. At this time, all cell phones on the scene will be in a network search state and will lose the signal of the communication base station. The cell phone is specifically manifested as searching the network, no signal, only service system, etc. Even the calling member cannot establish a normal voice call, give full play to its role, and complete the cell phone signal blocker.

For paper application methods, it can be used. cell phone signals are within a certain frequency range. After the cell phone and the communication base station are connected by electromagnetic waves, data and sound are transmitted in a specified serial port baud rate and in a coordinated manner. If the cell phone is blocked, you will not be able to make normal calls.

When using cell phone shielding, it is best to purchase some professional cell phone signal shielding equipment. Professional hardware configuration cannot be achieved by some simple systems. In areas where the magnetic field or electromagnetic field is abnormal, it will have a certain effect on the cell phone signal. The built-in cell phone flight mode in the cell phone is also a convenient cell phone signal method for users to reach some places where cell phone signals are not allowed to be generated.

In the past two years, various types of cell phone signal blockers have been varied, which makes people dizzy and overwhelmed. However, not all products are suitable for people to use. Some products are common, so they are not suitable for people to use in other industries. There is a very special blocker, which also appears in front of people. It is called wireless signal blocker. So what are the advantages of this kind of product?

When we use wireless signal blockers, you will find that no matter where we are, as long as we can turn on such a blocker, no one can find our network signal. In other words, household products are more effective than general public products. In such an environment, we can easily block all data signals. However, if we use a public type of blocker, you may also have the problem of unstable shielding effect. Therefore, we need to understand the actual application effect.

What are the advantages of wireless signal jammers? The following are the four major advantages of wireless signal jammers:

1. Wide application occasions

Wireless signal jammers are mainly used in examination venues, but not limited to examination venues. They can also be used in prisons, gas stations, to prevent mobile bombs, petrochemical plants, gas stations, detention centers, interrogation rooms, people's courts, labor camps, conference rooms, cinemas, churches, libraries, school dormitories, special security and confidentiality places (customs offices, reception halls, mobile vehicles, mobile political and business dignitaries protection sites), etc.

2. Strong purpose

Wireless signal jammers can be mainly used in the national college entrance examination, domestic postgraduate entrance examination, adult examination, self-study examination and various college examinations, as well as various junior high schools, vocational high schools, vocational high schools, prisons, detention centers, conference rooms, etc., to prevent the negative effects caused by cheating with cell phones, sending text messages indiscriminately, communicating with people outside the prison, collusion, etc.

3. Shielded signals are diverse

Effectively shield GSM/CDMA/DCS/PHS/TD-SCDMA/WCDMA/WIFI/TD-LTE/FDD-LTE.

4. Model advantages

1. Adopt high heat dissipation aluminum alloy housing, low operating temperature, and more stable shielding effect.

2. Built-in silent fan, low noise during operation.

3. Independent adapter. 12V/24V DC power supply system operation, convenient for vehicle-mounted mobile operation.

4. The external antenna design, unified one-end socket makes the appearance more beautiful and appropriate. And it has an anti-drop transmission design, and the antenna and the server have a marking working frequency band for easy one-to-one correspondence.
