For those who can use mobile phones, the stronger the GPS signal is, the better
Poor mobile phone signal jammer equipment may affect the routine work of other electronic products due to defects in the production process and design scheme, but professional equipment in technical professional places will never affect other electronic products. In the routine work, this is mainly because the professional mobile phone signal blocker equipment is not a simple circuit board splicing but a fully enclosed modular design structure. Each shielding control module matches a mobile phone data signal frequency band, and the mobile phone signal is shielded. When the device is running, each shielding control module only affects its corresponding frequency band, and will never cause any harm to other electronic products.
Yesterday, everyone was looking for data signals with their mobile phones. Why do they still need the 88 system? In fact, there are two levels of this objective fact. For those who can use mobile phones, it is natural to expect that the stronger the mobile phone signal, the better. However, for criminals, business secret enterprises and other unique venues, it is natural to reasonably affect the mobile phone signal in order to improve security and information confidentiality. Let’s take the prison cell. For the criminals detained here, it is a must for the criminals not to touch the outside world. Otherwise, how can we comfortably accept the renovation? In addition, if there is no mobile phone signal, even if you leave your mobile phone in your hand, you will not be able to. It can communicate with the outside world, reducing the occurrence of unreasonable things such as escape.
Why do you say is the necessary equipment for the examination room? Recently, a device that has hit major news platforms suddenly became popular. In fact, the reason is that the college entrance examination is approaching, and major schools have installed it in the examination room one after another, and it has been taken out and discussed again. It is an examination signal blocker. Now there has been another wave of buying cell phone GPS jammers. In fact, this kind of equipment is a shield that can isolate communication signals, which can help the examination room to prevent the phenomenon of cheating by using communication equipment. In the face of various communication cheating methods that are constantly proliferating, it is the best countermeasure. Generally speaking, if a candidate wants to cheat in the examination room, they must use communication equipment to receive and send information in order to get in touch with outsiders and achieve the effect of cheating. Therefore, based on this premise, a The device called the test mobile phone signal jammer came into being. It can isolate the communication signal and WIFI signal of the mobile phone within the effective shielding range, so that the communication device cannot receive any information within the shielding range, and there is no It is precisely this effective countermeasure. Today's mobile phone test signal GPS jammers have become a must-have equipment in major test rooms, allowing schools to build a more secure test environment.
Confidentiality of exam papers is the lifeblood of exam work. To this end, the Chengdu Examination Management Center cooperates with the public security department, and the security department conducts the construction and maintenance of standardized test centers for the county and district test paper command centers, installs the test room , realizes the full coverage of the signal shielding range, and accepts the implementation of security and confidentiality work. And meet the standard before the exam. At present, the city's examination room offices have achieved all-round, no dead ends, high-definition video surveillance. In order to ensure the fairness of the college entrance examination, the education department has equipped more than 600 mobile phone signal jammers gps in the examination room and more than 1,300 metal detectors. It is also planned to send a radio monitoring vehicle to strengthen the monitoring and prevention of cheating in exams. Crack down on the sale of cheating equipment, purify the surrounding environment of test centers, and crack down on illegal and disciplinary violations of cheating.
A new Jammer problem has emerged in prisons in many countries Jammer prevents leakage through communication tools such as mobile phone signals
The key to shielding the GPS signal is to check the supported frequency of the selected signal jammer The principle of the test signal jammer is to isolate the communication signal
