Handle the GPS channels in the frequency bands that are not concerned by the mobile phone Jammer


  In order to ensure smooth signals around the campus, the operator has arranged in advance communication engineers to test the entrances and exits of each test center and the rest area for parents accompanying the test, and expand the hardware and software of nearby base stations to ensure the communication needs of parents in the test area during the test. We have done our best to keep your communication flowing, except for the signal being blocked during the exam. Every year in the college entrance examination, in order to prevent fraud in the examination, all communication signals in the examination room will be shielded. There are common mobile phone signal blockers in the test room: at the same time, there is a radio monitor outside the test room that can help to deal with electromagnetic waves in those frequency bands that the mobile phone blocker can't care about. Signal, real-time monitoring of radio wave signals of unknown origin. The working principle of the 88 used in the college entrance examination is to bury useful electromagnetic wave signals in a large number of useless signals. Under normal circumstances, when we use a mobile phone, the mobile phone is first connected to the base station of the operator, and the radio wave signals sent by both parties come and go. However, once the mobile phone signal jammer is turned on, it will "beat gongs and drums" around the mobile phone, and emit a "noise" radio wave signal that is many times more powerful than the received base station signal. The mobile phone cannot hear what the base station is talking about and cannot receive the base station normally. signal, the connection between the two is cut off. Whether making calls, texting, or various other functions, they are all paralyzed.

GPS channels frequency phone Jammer

  We all know that now people are paying more and more attention to the working atmosphere, and now it is really necessary to create a peaceful and safe working environment, usually this goal is difficult to achieve, almost all people talk loudly and disturb other work that wants to be quiet through their mobile phones People in the environment, like there is usually a phone in the office, people can use the phone to call customers if the need arises. But are there any useful devices out there that can help develop a safe and quiet environment? Now the answer is yes, in order to catch up with this technology, can now be a good assistant in the office. We all know that good working conditions can help people be more productive in order to get their work done in a timely manner, especially for those who want to be quiet to do this work, now usually people are shielded from mobile phone noise in the office , then use a cell phone jammer device is needed now, here, if you are looking for desktop 88 that can help you in this situation, then you can look for example "High Power 6 Antenna 3G 4G Full Band Cell Phone Jammer ", then you can see more details of the high power 3G 4G cell phone jammer.

  Wireless communication technology uses radio waves to suspend communication. The functional characteristics of radio waves are determined by its frequency. Everyone's mobile phone must send radio waves that meet the requirements in order to connect to our communication operator's base station. The fundamental principle of the device is to radiate the same wireless frequency as the mobile phone, because the frequency is the same, the mobile phone cannot tell which signal is the regular base station signal, and then "interference". So how does this kind of Internet interference work? It's actually not that difficult. It is to use the method of circulatory system to continuously play the interference wavelengths that match the three signals of the video, covering the three wavelengths at one time, and the spacing of this type of circulatory system is very small, so that the mobile phone basically has no chance to speak. sit. The main principle of signal shielding and signal GPS jammers is to spread loud noises in the frequency band of mobile phone applications, disrupting the inclusiveness and push of normal mobile phone signals. This small item is not only used to prevent fraud during exams, but also often used to prevent fear of attacking in politics and national defense.

  Due to the requirements for effective shielding distance, the signal strength of mobile phones is very different indoors and outdoors. The shielding effect of is greatly affected by the distance of nearby communication base stations and whether it is used through walls. This causes the shielding effect to be very different between indoors and outdoors. This requires in-depth knowledge of signal transmission. The effective shielding distance in general equipment parameters is the distance measured for a specific environment. Therefore, everyone must consider comprehensively and choose carefully when choosing a mobile phone jammer device. For example, indoor mobile phone signal jammers gps are more suitable in the examination room. Since this kind of indoor signal jammer does not need to use a shell to deal with bad weather, because there is an invigilator, there will be no situation where candidates maliciously destroy the mobile phone signal jammer. lower cost of investment. At the same time, it pays more attention to the performance of silent and noiseless, heat dissipation, continuous work, etc., and is more suitable for use in the examination room.
