Libraries use cell phone jammers

1. The use of cell phone signal jammers should not be exchanged at the expense of public mobile communications.​​
Among those who use cell portable jammer, some are to prevent cheating in exams, some are for the quietness of the venue or the confidentiality of meeting information, these are all out of good intentions and purposes. But there are also those for self-interest. For example, the owner of a public phone may use a jammer to interfere with the mobile communication tower near his business location, so that people who work near the public phone they operate will not work well, and they will change it. Use public telephone calls to increase your financial income. In addition, mobile communication operators may also use jammers to harm the interests of each other, so that they can gain an advantage in some local competition in the same industry.

The above list is the purpose of people using mobile phone signal jammers, but no matter what the purpose is, it should not be exchanged at the expense of public mobile communication.

There are three reasons for the mobile phone signal jammer to disturb the signal of the mobile communication tower:

One: The user of the mobile phone signal jammer completely ignores the communication needs of outsiders, and the target is wrong. The mobile phone communication should be restricted for a small number of people (such as candidates), but the target is expanded to other ordinary people around.

Second: Improper use method, due to improper installation position of the mobile phone signal jammer or too large transmission power setting, it should be controlled in a small range but not properly controlled.

Third: The purchased mobile phone signal jammer does not meet the approved standards for radio equipment, the power exceeds the standard, or the inferior substandard product. Find out the reason, in order to overcome its influence on the mobile communication signal, it is actually very simple: first, use the standard products produced by regular manufacturers, secondly, choose the installation location and direction of action, and thirdly, set the appropriate transmit power. , it is enough to limit its transmission signal to a small closed area. As long as the above three points are achieved, the impact on the nearby mobile communication towers can be minimized.
