What safety issues should be paid attention to when using portable signal jammers?
1. The application of portable signal jammers should avoid the masses to prevent the mobile phone signals from affecting the masses.
Among the customers who use portable signal jammers, some are to prevent people from cheating in the examination room, and some are to create a quiet environment without electronic communication disturbance in the main venue, all of which are to create a quiet environment on special occasions achieve the purpose. In fact, some people do it for their own benefit. For example, if they operate a business in a public telephone hall, they make full use of the shielding network they undertake to affect their own business location. For example, nearby mobile communication base stations and signal amplifiers are installed to allow them to operate It is difficult for the staff around the public telephone booths to use mobile phones, but instead change their source of income to voice calls in public telephone booths. In addition, mobile communication network operators may also use portable signal jammers to harm the rights and interests of the other party, allowing themselves to gain advantages in some local peer competition. In addition, the portable signal jammer is also very easy to add mobile phone software to become a real monitor.
The above listed are the effects that many people use portable signal jammers, but no matter what the purpose is, they cannot be obtained at the expense of mass mobile communications. In fact, according to scientific research, it is possible to apply a portable signal jammer without affecting the normal activation of mass mobile communications. There are three reasons for the data signal of the mobile communication base station:
First, the user of the portable signal jammer does not consider the communication needs of the smiley face at all, and the function object is wrong. They're supposed to limit cell phone communication for a small group of people (like students), but they extend their targeting to other general groups in the vicinity.
Second, the operation method is unreasonable. Because the portable signal jammer is placed in an unreasonable place or its transmission power is set too high, it should be controlled in a local area but it is not well controlled.
Third, the purchased portable signal jammers do not meet the approval specifications for radio equipment, the output power exceeds the standard, or fake and substandard products. Find out the reason, in order to get rid of the power hazards of mobile communication signals, it is actually very simple: first, use a reliable manufacturer to produce qualified products, then choose the installation location and direction of the effect, set a moderate transmission power, and limit its transmission signal in a closed area. If the above three points can be achieved, the impact on surrounding mobile communication base stations can be minimized.
2. The unreasonable use of portable signal jammers in colleges and universities may cause unnecessary damage to the body.
Basic theoretical analysis shows that when the portable signal jammer is working, if the setting is unreasonable and the transmission power is too large, in a closed space such as a local conference hall or classroom, radio waves will accumulate in a small space. According to the original and Multiple reflections from the walls, ceilings, and road surfaces of the outer partition will expose the workers in the room to severe electromagnetic radiation. According to the survey, the college entrance examination and the high school entrance examination are the places where the most portable signal jammers are used, and some of the defendants (the college entrance examination inspection staff, students and teachers) are upset and have no time and energy in some examination places where jammers are used. Some students may even have headaches due to the centralization of the law. There are various indications that if the transmission power of the backpack jammer is turned on too much, it will affect the normal thinking of candidates in the examination room. Everyone knows that electromagnetic waves are transmitted randomly in mid-air. Portable signal jammers can block the data signals of mobile communication base stations in a special area and achieve their limited purpose. At the same time, they will also damage the body to varying degrees. Health, so be sure to use portable signal jammers with caution.
