The Wifi signal is very strange, but if it's strong it has a full grid. When it is weak, there is no signal at all. Mobile company staff repeatedly check that the line is normal. It may affect normal communication and internet access. After some testing, I guess I used a cell phone jammer to block the wifi signal. The wifi signal broke into his body. I bought a jamming device installed in my home. Using jammers to block signals at home, I'm not sure if community radio signals will occasionally appear. I didn't worry about my neighbor's feelings.
Signal jammers interfere with the signals of mobile phones such as conference rooms and test rooms. Radio signal jammer have become a popular tool to avoid the effects of mobile phone communications during meetings and tests, and to prevent information leaks and test fraud. Existing signal cloaking devices primarily manually control jammer switches. The program cannot be set automatically. The work strength is high. There is inconvenience when using it. The cloaking device does not have a monitoring device. It cannot be repaired in a timely manner. Excessive temperature of the jammer causes circuit damage.
