Can 1 test room mobile phone signal jammer shield 1 classroom?

source:Industry News release time:2020-11-30 Article author:sznbone Popular:Prison Jamming system

  Important admissions exams, qualification exams or final exams need to install a mobile phone signal jammer to shield the electronic signals around the exam room and prevent possible electronic cheating. So, how much area can the mobile phone signal jammer in the exam room shield? Can only one jammer in an exam room achieve the purpose of shielding? How many jammers should be used in a teaching building?

  First of all, we need to know: The mobile phone signal jammer in the examination room has a theoretical shielding range, which is about 0-20 meters in radius. But please note that this is a theoretical distance. The actual effect should be combined with the local signal strength, especially whether there is a signal base station nearby. If there is a signal base station within 200 meters, the shielding effect will be compromised. In addition, the wall will weaken the shielding effect of the shield. As the signal is stronger near the window, the shielding effect will be weakened.

  The standard classrooms in schools are generally about 75 square meters, and each classroom is equipped with a shielding device to achieve better results. It can be placed in the middle of the classroom and can be shielded to the greatest extent. Of course, this must be determined in conjunction with the power supply wiring. It is also common to place the shield at the podium. If it is a larger classroom or there is a base station nearby, you can place two jammers in each classroom, one at the front and one at the front. Because the shielding signal is superimposed and enhanced, a better effect of 1+1>2 will be achieved. In addition, in order to ensure the shielding effect, another shield can be arranged every 10-20 meters in the aisle of the teaching building. Finally, it should be noted that the installation height of the shield is preferably 1.5-2 meters from the ground.

  MDPB-5E (6 channels) upgraded version of mobile phone signal jammer is a mobile phone signal jammer specially developed and produced by adopting international advanced shielding technology to meet market demand. The equipment has undergone a brand-new upgrade, changing from 5 channels to 6 channels increases the shielding effect of the device itself on the signal. At the same time, the newly added 4G frequency band solves the disadvantages that other products cannot shield the 4G frequency band, and the shielding effect is better than other similar products. The shielding effect is stronger, the performance is more stable, and it is easier to be recognized and accepted by customers.

  MDPB-5E (6 channels) upgraded mobile phone signal jammer can automatically form a shielding magnetic field within the specified range when entering the working state, forcibly disabling mobile phone signals, MDPB-5E (6 channels) upgraded mobile phone signal jammer only works Mobile phone communication signals are shielded without causing interference to other electronic devices, which has also become its rare advantage. The advent of the MDPB-5E (6 channel) upgraded version of the mobile phone signal jammer may completely solve the harm caused by the information leakage of communication facilities to users, allowing people to enjoy the speed and convenience brought by high-tech to mankind while ensuring The security of its information.

  MDPB-5E (6 channel) upgraded mobile phone signal jammerIts most important applications are in examination rooms, prisons, gas stations, mobile phone bomb prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters , Churches, libraries, school dormitories, special security and confidential occasions (confidential offices, negotiation rooms, mobile vehicles, mobile politicians and business dignitaries guarding) scenes, etc., and mobile phone signal jammers are becoming more and more important in social life. .
