What are the advantages of high-power signal jammers

Regarding the signal jammer, it is specially designed for prisons, military areas, oil fields, gas stations, etc. It is to supervise the seriousness and quietness of examination rooms, prisons, detention centers and other places, and to ensure the fairness and impartiality of examinations. mock exams. It is a product used for communication supervision, a special device used to suppress mobile phone signals. The characteristics of high-power mobile phone signal jammers are mainly high power and large shielding range. Using high-power mobile phone signal jammer can automatically form an effective mobile phone signal shielding magnetic field within the specified range.

When purchasing a high-power wireless signal jammer, you must first know where to use it. If it is used indoors, such as the examination room, conference room, office, etc., you can use a low-power model. If it is an outdoor open area, you need to use a large Powerful wireless signal blockers can achieve effective shielding distance. Generally speaking, the external antenna is usually used for high-power machines. Since the wireless signal jammer antenna is external and extends outward, it occupies a larger space than the built-in antenna, but it is also The externally extended antenna, the shielding effect of the external antenna is more stable. The high-power wireless signal jammer is a drag box design, and the volume is very large.

The high-power wireless signal shielding device adopts a pure aluminum chassis, which is dust-proof and shock-proof. It adopts external AC power supply. The equipment adopts a modular design, and each module can be switched on and off separately. Six high-power shielding modules, the frequency can be customized and combined arbitrarily. The device control methods are flexible and diverse. It has ultra-high frequency broadband ganrao technology; high effective power (channel power), large influence radius, high power is mainly used in large areas and should be able to shield 200-500 meters; high power shields generally use fans , It can be used continuously for 365 days. The development jammer has a high-power cabinet jammer, and the prison wifi jammer is generally used for 365 days. However, when using a high-power mobile phone signal jammer, it is recommended to keep a distance of more than 2 meters. The radiation at this time is very small and will not cause harm to the human body. According to the "Basic Standard for Ionizing Radiation Protection and Radiation Source Safety", the annual dose of radiation received by a normal person shall not exceed 1mSv. National standard GB 15208.1-2005 regulations.

The high-power mobile phone signal jammer is designed with aluminum alloy metal shell, which is waterproof, strong, and prevents criminals from deliberately destroying. The voltage standing wave ratio (VSWR) circuit protection mechanism can prevent the system from being burned out due to short circuit or disconnection of the antenna. High-power mobile phone signal jammers are generally used in outdoor playgrounds, open prisons and other places. The power of D-E high-power jammers can be adjusted, and each channel can be jammed separately. The effect is much better than low-power signals, and the coverage is far!

The mobile signal jammer cuts off the communication between the mobile terminal and the mobile base station by transmitting a strong wireless signal, but it will not interfere with the signal communication in the control area except the shielded frequency band. Once the Anti tracker Jammer is turned on, all standby phones will show "No Service". Just like power off, incoming calls are blocked. When the jammer is closed, all phones automatically re-establish communication and provide full service.

The high-power jammer also has a perfect self-protection function. When the equipment has a fault alarm such as overheating, output overpower, standing wave, etc., the jammer will automatically shut down the faulty module to avoid damage to the jammer; high precision, high efficiency, high Gain; anti-corrosion, long life, strong wind resistance, special reflective layer technology, good consistency, no deformation, easy to transport and install.

However, it is not that the higher the power of the signal jammer, the better. The higher the power of the signal jammer is not necessarily better, because the greater the power of the signal jammer, the wider the shielding range, and it is easy to interfere with the normal operation of the nearby communication base station. work, which will affect the normal life of the surrounding residents; at the same time, the greater the power of the signal jammer, the more interference electromagnetic waves it will generate, and the more radiation it will generate, which may have an impact on the human body; finally, due to production The cost of high-power signal jammers is higher. When purchasing a signal jammer with higher power, the required capital cost is also higher. It is not cost-effective for some places where small and medium-sized signal jammers can meet the shielding requirements. . Therefore, when purchasing a signal jammer, you must consider your own needs.
