Mobile phones and games have become the most serious challenges in education. Banning the use of mobile phones is a good management method. Instead of checking the room and taking strict control measures, mobile jammers are an effective method. The principle of a telephone signal jammer is very simple. The frequency used to transmit affects the frequency of the mobile phone signal. Whether the equipment out of range will affect the surrounding people must be carefully evaluated. He said that the school is only used at night.
The school is not an expert and does not understand the consequences of installing jammers, so it must listen to the voice of the regulator. It is increasingly used in theaters, hospitals, government agencies, etc. Mobile jammers can almost be purchased online. Some manufacturing companies use confidentiality as a selling point.
Advanced technology has brought convenience to mankind. Since the transmitting Power of the base station used for mobile communication is extremely high, the closer the shielding effect is to the base station, the worse the shielding effect will be. In foreign countries, mobile phone signal cell phone blocker are not new. In the past two years, sales have begun in the Chinese market. Cell phone jammers were installed in some parts of the classroom to prevent cheating. However, for an increasing number of citizens, the abuse of such devices will damage citizens’ freedom of communication.
This depends on the signal strength at the blocked location. The maximum blocking radius of the signal jammer is 20 meters. It is actually a large area. The most common signal jammers interfere with one or two frequency bands. The Power jammer cut off the highest frequency band 868MHz. The total output of this device is 15W. The Power supply is 50-60 HZ. After fully charged, you can work for a long time. The mobile jammer, AC adapter and 5 antennas are all part of the device. It can also be used in cars.
