Mobile phones and games are the most serious challenges facing education. Banning the use of mobile phones is a good management method, and gsm jammers are an effective way to inspect rooms and take strict control measures. The principle of the gsm signal jammer is very simple. It affects the frequency of the mobile phone signal by the transmitted frequency. We need to carefully evaluate interfering devices to determine if they affect the people around them. Small jammers run on batteries, and some large sites must use powerful equipment.Previously, it was designed for military agencies. Terrorists can use their mobile phones to launch bombs, use signal jammers to prevent attacks, and 5g jammers to prevent communications in sensitive areas.
UAV jammers are essentially a radar / radio blocking system that provides defense for strategic targets within a radius of 3 kilometers. This drone jammer can interfere with the signals of large drones up to micro / nano drones, it uses radar, optical sensors and other sensors to detect and identify drones, and varies from hundreds of meters to several thousand depending on the type of drone Assess its potential threats within meters. The jammer is based on a large threat library and real-time analysis of control signals, which can interfere with the link between the drone and the pilot and / or its navigation.
Is the radiation produced by signal jammers harmful to human health? Regarding radiation, we know that as long as electronic products have large and small radiation. Any piece of electrical equipment has radiation. The rest of our mobile phone signal shielding is far below the national standard, and it is not calculated in the ear every day, so it is almost harmless to the human body.Why are some phones not protected by a signal jammer? The signal emitted in the test room is uneven and may have weak points, so the shielding effect in these places is different. Similarly, the sensitivity of the handset is different. You can protect the signal frequency, and the frequency of the phone is not in the band filter.
