In order to protect the interests of the vast majority of candidates and improve the fairness of the exam, necessary restrictive measures must be taken against the cheating of a few people. The exam management department has adopted the method of installing a full-band jammer.

During the examination period, the examination room and the surrounding environment of the examination room will be closely monitored in all directions. The monitoring stations and monitoring vehicles will all enter the state at that time, and will conduct comprehensive monitoring on some radio frequency bands. Once abnormal signals are found, full-band jammers will be taken immediately Jamming signal measures block the signal. In addition, technicians can also judge the direction according to the direction finder, and assist relevant departments to seize cheaters.

Some parents of candidates feel uneasy about this, worrying that it will affect the normal performance of their children in the college entrance examination. In fact, the parents of candidates have no concerns about this aspect at all. These devices will not cause harm to the bodies of candidates and test staff, and this full-band cell phone jammer can be completely silent, and will not affect the normal performance of children's college entrance examinations. play.

Whether any kind of electromagnetic wave emitting equipment is harmful to the human body depends on the specific absorption rate of the human body to electromagnetic waves. The radio frequency radiation safety standard SAR recognized by the International Non-ionizing Radiation Protection Committee is up to 2.0, and the standard in my country is 1.5. The transmission power of the current wireless communication base station transmission tower is generally 40W~50W, and the specific absorption rate value of the human body for electromagnetic waves is below 1.0 when the distance from the transmission tower is 20 meters to 30 meters. The full-band jammer used in the examination room is a micro-power device, and its transmission power is generally less than 3W. In this case, the specific absorption rate of electromagnetic waves by the human body is negligible. Therefore, the full-band jammer used in the examination room does not pose a hazard to human health.

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).
