What principles should be followed when using a cell phone signal jammer? from dojammer's blog

The use of a cell phone signal jammer should not be at the expense of public mobile communications.

Among individuals or units that use cell phone signal jammers, school exams use cell phone signal jammers to prevent cheating in exams, and conference venues use cell phone signal jammers to keep the venue quiet or keep conference information confidential. These are all for good intentions and purposes. But there are also those who use them for their own selfish interests. For example, a household owner who operates a public telephone may use a mobile phone signal jammer to interfere with the mobile communication base station near his business location, so that people who do business near the public telephone he operates cannot use their mobile phones, but use public telephones to make calls instead, thereby increasing their own economic income. In addition, mobile communication operators may also usecell phone signal jammers to harm each other's interests and gain an advantage in some local competition in the same industry. In addition, cell phone signal jammers can also be easily added with software, becoming a veritable eavesdropping device.

The above are the purposes for people to use cell phone signal jammers, but no matter what the purpose is, it should not be at the expense of public mobile communications. In fact, according to research, it is possible to install a cell phone signal jammer without affecting the normal use of public mobile communications.

There are three reasons why cell phone signal jammers disrupt mobile communication base station signals:

First, the user of the cell phone signal jammer completely ignores the communication needs of outsiders and acts on the wrong object. It should limit the mobile phone communication of a small number of people (such as candidates), but expands the object to the surrounding people.

Second, improper use methods. Due to improper installation of the cell phone signal jammer or excessive setting of its transmission power, it should be controlled within a small range but is not well controlled.

Third, the cell phone signal jammer purchased by the user does not meet the radio equipment approval standards, the power exceeds the standard, or it is a low-quality and unqualified product.

After finding the cause, in order to overcome its impact on mobile communication signals, it is actually very simple: first, use qualified products produced by regular manufacturers, second, choose the installation location and direction of action, and third, set the appropriate transmission power to limit its transmission signal to a small closed range. As long as the above three points are achieved, its impact on nearby mobile communication base stations can be minimized, and it will not affect the normal calls of the surrounding people.
