What safety issues should be paid attention to when using portable signal jammers

by LIU YIFA 26 Jun 2024

1. The application of portable signal jammers should avoid the crowd to prevent the crowd's mobile phone signals from being affected.

Among the customers who use portable signal jammers, some are to prevent cheating in the examination room, and some are to create a quiet environment without electronic communication disturbance in the main venue. This is to create a quiet environment in special occasions. In fact, some people are for their own interests. For example, if you operate a business in a public telephone hall, you can make full use of the shielding network you bear, affect your business location such as: nearby mobile communication base stations and installed signal amplifiers, so that the staff around the public telephone booths you operate are difficult to use mobile phones, but change their source of income to public telephone booths. Voice calls. In addition, mobile communication network operators may also use portable signal jammers to harm the interests of the other party, so that they can gain advantages in some local competition. In addition, portable signal jammers are also very easy to be added with mobile phone software, becoming a veritable eavesdropper.

Listed above are the effects of many people using portable signal jammers, but no matter what the purpose is, you can't give up the cost of mass mobile communication to obtain it. In fact, according to scientific research, it is possible to use portable signal jammers without affecting the normal start-up of mass mobile communications. There are three reasons for the signal of mobile communication base stations:

First, the users of portable signal jammers do not consider the communication needs of smiling people at all, and the function objects are wrong. They should limit the mobile phone communication of a small number of people (such as students), but they expand the target to other ordinary groups nearby.

Second, the operation method is unreasonable, because the portable signal jammer is placed in an unreasonable place or its transmission power is set too large, it should be operated in a local area but it is not operated well.

Third, the purchased portable signal jammer does not meet the approval specifications of radio equipment, the output power exceeds the standard, or it is a counterfeit and unqualified product. Finding out the reason, in order to get rid of the power hazard of mobile communication signals, is actually very simple: first, use reliable manufacturers to produce qualified products, then choose the installation location and direction of the effect direction, set a moderate transmission power, and limit its transmission signal to a closed local area. If the above three points can be achieved, the impact on the 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.

Theoretical analysis shows that when the portable signal jammer is working, if the setting is unreasonable and the transmission power is too high, in a closed space such as a local conference hall or classroom, the radio waves accumulate in a small space, and are reflected by the walls, ceilings, and floors that are separated from the outside, which will put the people in the room in a serious electromagnetic radiation. According to the survey, the college entrance examination and the high school entrance examination are the places where the portable signal jammer is used the most. In some examination venues where the cell phone jammer is used, some of the defendants (college entrance examination inspection staff, students and teachers) are upset and unable to concentrate, and some students even have headaches. Various signs show that if the transmission power of the backpack jammer is too high, it will affect the normal thinking of the candidates in the examination room. As we all know, the characteristics of electromagnetic waves that are transmitted freely in the air, while the portable signal jammer promotes the isolation of the mobile communication base station data signal in a specific area and achieves its limited purpose, it will also damage health to varying degrees, so the portable signal jammer must be used with caution.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
