Mobile jammer prevents students from cheating on mobile phones

Why do I need to install a cell phone jammer on my phone? During the exam, some students will send messages to each other via mobile phones, check their composition on the Internet, and install protective sleeves to prevent students from cheating on their phones. Many students lie in bed after class or late study. There are a lot of bad information on the Internet, which is not conducive to the growth and learning of students. Some students send text messages and phone dates before going to bed late at night to affect the next day.

The number of mobile phones is increasing rapidly. Using mobile phones is a problem. Devices that interfere with the radio waves of commercially available mobile phones are installed in many places. The ringing of the mobile phone in the cinema made me feel uncomfortable. Interfering devices that suppress harmful signals may emit interfering radio waves in the same frequency band used by mobile phones and PHS. It will worsen the radio wave situation. Smart phones are very useful because they can do many different things. Personal privacy may have been disclosed. Mobile cell phone jammer, can easily access the Internet. It not only supports 4G and 3G smart phones, but also supports the latest frequencies. If the mobile phone and the base station are close to each other, the radio waves may be strong, and the original effect may not appear. When the switch is turned on, nearby mobile phones are not in range. Depending on the GPS jammer, performance will vary. It has a simple design, so it cannot stand out.
