jammer

The weather can also affect the effectiveness of the jammer

1. At present, the power and channel of each base station are different, and the distance from each base station to the prison is also different.


2. It is generally recommended that the gsm jammer is located within a monitoring area of 200 meters or 300 meters without the need for a base station laptop to be installed.


3. If there are base stations, it is necessary to consider the impact of strong signal shielding on high probability base stations.


4. The scale, number of buildings, structure, height, and floor height of each prison vary.


5. The distribution direction, power, terrain and other factors of mobile phone base stations around each prison are different, and the strength of Mobile phone signal signals transmitted by remote base stations are also different

Generally, the transmission power of the Mobile phone jammer is tested within 30W in the test room, so the theoretical shielding range of the Mobile phone jammer in the test room is about 0~20m. But please note that this is the theoretical distance. The actual effect should be combined with local signal strength, especially when there are signal base stations nearby. If there is a signal base station within 200 meters, the shielding effect will be greatly reduced. Walls can also weaken the shielding effect of radio interference devices on laptops. Due to the strong signal near the window, the shielding effect will be weakened. The standard classroom of the school is usually about 75 square meters, and each classroom is equipped with a Mobile phone jammer to achieve better results. It can be placed in the middle of the classroom for maximum protection. Of course, this must be determined in conjunction with the power wiring. It is also common to place cell phone jammer on the podium.

• In the same environment, the base station signal can also be affected by wind interference and air humidity./li>
  
• This can also cause fluctuations in the signal field strength. In addition, there are differences in the intensity of the infield and outfield./li>
  
• The adverse effects of ground building structures and metal objects on GPS jammers are very complex for mobile devices./li>
  
• Based on the project budget, the selection of mobile jamming devices should be reasonably planned. The selection of shielding equipment should consider shielding radius (i.e. power), performance stability, and service life./li>
  
• It must also be determined based on the on-site environment. At the same time, consider using mobile phone jammers with adjustable radius (i.e. adjustable power) or using directional antennas to control the main transmission area (direction) of the shielded signal.

The most important place to use the Mobile phone jammer is the school examination room, especially the high school entrance examination, college entrance examination, postgraduate entrance examination, CET-4 and CET-6. There are also many schools that have installed jammers. They use mobile phones for a long time in class, and usually use mobile phones in the Final examination. Some schools even use mobile phone jammers in their classrooms. So how can we install a mobile phone blocker in school exam rooms to achieve the best results? We will elaborate on the different situations mentioned above.

Super effective Mobile phone jammer

The purpose of the gsm jammer is very clear and simple in frequency: to prevent communication on certain frequencies. However, since it is not easy to prevent devices from communicating with other devices, the solution to prevent this type of information transmission is very simple, similar to DDoS attacks: introducing noise at a specified frequency, unnecessary information will saturate the tape. Prevent them from obtaining true information. signal jammers can be used to interfere with various types of communication or devices such as cellular networks, radar, Bluetooth, GPS, infrared, etc. Although widely used

GSM is the abbreviation of Global System for Mobile Communications and is the most widely used digital wireless telephone technology in the world. It is a standard that describes the 2G cellular network protocol. It uses the base station to generate a stable electromagnetic field radio frequency signal to relay information. When the magnetic field is in the metal, it will produce interference signals. Rubezh can be detected and recorded. The Doppler effect and triangulation are used to determine the precise coordinates of the target by analyzing the signals recorded by the base station. Once Rubezh has captured the identified target, the data is sent to the monitoring center via the GSM network, including the Defense Management Center of the Russian Ministry of Defense and the Russian Space Iraq Air Defense System Command and Control Center.

This jammer will work later to remove the signal and eventually they will disband on their own and later we will also cooperate with Telkom," Deni said at the Garut county government secretariat live, quoted from Antara on Monday.

How cell phone jammer work
Jammers work by sending radio frequency signals to the nearest BTS tower. The signal is basically on the same frequency as a cell phone, and strong enough to cover it.

The jammer signal and the cell phone signal eventually collide, and the process then causes a loss of communication between the cell phone and the base station.

Depending on the make and model, jammers come in different variants and capabilities. Common jammer devices block one of two cell phone frequencies, tricking the phone into thinking it doesn't have BTS service because it only receives one frequency.

16 band 5g jammer

Mobile phone jammers work similarly to mobile phone jammers because they emit the same radio frequency as the mobile phone's operating frequency. This will cause enough interference and you will not be able to connect the call to your phone. Currently, there are two types of cell phone jammers available. The first type is usually a small device that can block the signal from a cell phone tower to a single cell phone. The blocking frequency is 800MHz to 1900MHz. Most devices using this technology can block signals within a 30-foot radius. Mobile phones in this area do not display signals at all. Now you can politely ask them to leave quietly, or you can buy a cell phone jammer to leave them alone.

I will show you how to protect the mobile signal jammer. Before cleaning, plug in the electronic information protection device with the power plug. Do not wipe the electronic information protection with a damp cloth, and do not use cleaning fluids to protect the electronic information. The housing does not protect electronic information in water or humid places. To prevent water and moisture from entering the electronic information protection unit, the housing not only holds too much dust, but also houses a small interference machine to ensure a clean electronic information protection working environment, because it may Causes electrostatic adsorption, which may cause communication problems. The electromagnetic environment requires electronic information protection systems, and the impact on interference will be affected by external interference. For this, you should be careful! The AC socket enables the equipment of the AC power system to effectively filter the interference power. The WiFi blocker should be connected to the single-phase three-wire power socket and filter circuit at PGND. Long-distance wireless transmitter protects electronic information from radar stations and high-frequency equipment. Electronic information protector has very low heat and adopts natural cooling method. It is ventilated and protected around the vents, and the electronic information is protected with a 10 cm gap, and no wooden stakes are placed to keep the electronic information unobstructed.
