Free Number Blocking App For Cell Phone Has A Wide Range Of Applications

In many occasions in life, such as exams, meetings, etc., it is very inappropriate to use mobile phones. At this time, in addition to confiscating mobile phones in advance, you can use Free Number Blocking App For Cell Phone to block mobile phone signals and Wi-Fi signals within the scope of specific occasions. , without mobile phone signals and Internet access signals, everyone will not play with mobile phones, which is very good to achieve the expected effect. The invention of the mobile phone has indeed shortened the distance between people and brought great convenience to people's lives. The occasion brought a great disadvantage. Thus, the cell phone jammer market also followed. So, what occasions are cell phone signal jammers suitable for? The scope of application of mobile phone signal jammers is still very wide, some secret institutions, party and government agencies, colleges and universities, etc., you can learn more about it. Fairness and justice in all kinds of large and medium-sized examinations are the basic norms of society, and there are many examinations in life, ranging from small to junior high school entrance examination, high school entrance examination, civil servant recruitment examination and other national-level examinations. In order to avoid cheating by candidates, in various large and medium-sized examinations, it is necessary to use technical means such as mobile phone signal blockers to block the signals in the examination room, so as to meet the needs of mobile phones being unable to communicate and surf the Internet, which can also be very good. To prevent students from cheating behavior.

In simple terms, this is very similar to a sound signal. When the mobile phone tries to establish a connection with the base station, Free Number Blocking App For Cell Phone suddenly pops out, covering the communication signal with a very loud noise in the same frequency band, making the signal received by the mobile phone unorganized and undetectable. However, the power of the mobile phone signal jammer is not as large as possible. If this kind of interference emission is not scientifically calculated and unreasonably controlled, it will not be conducive to protecting the environment. Therefore, using a reasonable algorithm to control the transmission direction and power of the interference signal of the mobile phone signal blocker, it is necessary to maintain the shielding effect of the mobile phone signal, and to comply with the safety limit. Generally speaking, the closer to the base station, the stronger the field strength of the local BCH, the smaller the area where the jammer can achieve effective interference, and the general interference radius can only reach a few tenths of a meter to a few meters; the farther away from the base station, the stronger the field strength of BCH is. , the larger the radius of the mobile phone jammer to achieve effective interference, can reach more than ten meters to dozens of meters. Therefore, we should fully consider the size of the local BCH field strength before using the mobile phone signal jammer, and then determine the location, quantity and combination of the mobile phone jammer according to the size of the interference area.
