Multi-function jammer can shield all cell phone signals
The mobile phone signal jammers on the market are all full-band, which can interfere with all the 2G 3G 4G signals and 2.4G WIFI signals and Bluetooth signals of all the three operators of China Mobile, China Unicom and Telecom.
Some posts say that after turning off the automatic selection of the mobile phone network operator, it will not be interfered by manually selecting the network. In fact, this is not correct because the mobile jammer is aimed at all mobile phone frequencies under the three operators. It interferes, so no matter how you switch, it will be interfered, which means that no matter what the mobile phone card is, it is within the interference range of the jammer. This cannot be avoided by cracking the number band and band, because no matter which number or band you use, it is within its interference range.
There is also Bluetooth software that is not acceptable, because its frequency will also be interfered by jammers.
The only way is to install a mobile phone signal amplifier near the place where the mobile phone signal portable jammer is used to counter it. When the mobile phone signal becomes stronger, the jammer will be more difficult to jam.
How about the mobile jammer? This question cannot be generalized, it should be analyzed according to your specific situation. Here is a brief introduction to the purpose of the mobile phone jammer, 1) Slow start function, after the jammer is powered on, the working power will rise from zero to stable within 4 seconds. 2) Interference function, after the start is completed, the mobile phone within the range of action will be interfered within 35 seconds. However, under such high-intensity microwave irradiation, the human body generally has adverse reactions, but the degree of the reaction varies from person to person. Some people have strong resistance ability, and some people have weak resistance ability. The reactions that appear are also different, which can be divided into the following situations: the first step, visual impairment: seeing a flash of light or dots of light, black spots in the field of vision, seeing things suddenly enlarge or shrink, etc. The second step, sensory disturbances: the brain, eyeballs, face, lips and limbs have slight acupuncture and numbness. The third step, mood changes: unusually cheerful, hyperactive, depression, irritability, etc. The fourth step, thinking confusion: unable to concentrate thinking, fantasy, thinking disorder. The fifth step: fainting. Remedy after adverse reactions Our research has found that the characteristics of such adverse reactions are: sudden onset, rapid onset and rapid castration, throbbing pain, and intermittent periods.
When microwaves are transmitted in the air, the intensity of radiation decreases as a logarithmic function of distance. Microwave radiation generated by mobile phone jammers has very weak adverse effects on the human body at a distance of 12-15 meters. Candidates who have the freedom to choose to sit can easily find a farther seat to sit. Don’t be afraid if you experience adverse reactions after microwave radiation. It's easy to find a natural environment with good ventilation and tranquility. Sit reclining on a recliner. Under normal circumstances, a short rest will be fine. If the adverse reaction is serious, cold compress on the forehead can be used, and general sedatives can be effective if appropriate; if not, seek medical attention.
