In the annual exam season, all parties have begun to prepare for the exam. Invigilators have done everything possible to prevent high-tech cheating. Among them, the Apps To Block Telemarketers From Cell Phone dedicated to the examination room is still an anti-jamming device. There are many types and models of cell phone jammers. Users should clarify their needs before purchasing to avoid testing room accidents due to poor shielding effect. They are also paying attention to the correct method of use. Most schools use the test room style cell phone jammer which is suitable for long-term work and is durable. The second is how big are we in the shielded area? For example, for a room of 100 square meters or a venue of thousands of square meters, if the area is large, the power must be larger. If the area is small, you can consider choosing an adjustable shielding power. Then there are the frequency bands that need to be blocked. Are China Mobile, China Unicom, Telecom, and CDMA all blocked? Still only need to block part of the frequency band.

On the eve of the National Day and Mid-Autumn Festival, in order to prevent the recurrence of illegal acts such as drinking without a license, the Yantai Traffic Police Detachment equipped all units directly under the urban area with mobile phone signal jammers, and said "no" to interfere with interpersonal relationships. Apps To Block Telemarketers From Cell Phone As a new type of information security product, it uses a specific electromagnetic signal to form an electronic fence in the place that needs to be protected, so that the mobile phone cannot receive base station data and cannot establish contact with the base station. When connected to the vehicle power supply, an electromagnetic protective field can be formed around the police car, with a shielding diameter of tens of meters, which can effectively shield mobile phone signals without affecting the use of electronic devices such as mobile phones. The setting of the shielding diameter can not only effectively shield the police's mobile phone signal, but also minimize the interference to the mobile phone signals of the surrounding people.
