New semester begins at this September. And College entrance examination has ended several months ago. As a freshman who should have started military training that they must haven’t forget the days they have worked for it. Most Chinese students are nervous and excited for the “Black July” especially when they are at the College entrance examination room doing the paper. They won’t forget the strict teacher and hard-working classmates. And of course they must have good memories about the anti-cheating tools which called Cell Phone Signal Detector.

Maybe someone just failed to use mobile phones to cheat because of it.Cell Phone Signal Detector could scan at certain speed from the low-end to the higher-end. This scanning can interfere with the formation of garbled message signal received in the mobile phone so that the phone can’t detect the normal data sent from the base station. That means the phone can’t establish a connection with the base station. Then at that point the phone just can’t catch the signal and service system and so on. That’s why it can cut off the connections between Cell Phones.
There is a cell phone signal detection device which can detect cell phone signals at a distance. The signal once can be found and then you can take actions to stop it when you needed to do it. This cell phone signal detector has the ability to detect CDMA, GSM, DCS and PCS / 3G signals. It has different signal strength detection distance according to different given situations. And the maximum distance of it is about 15 meters.

This device is suitable for many mobile phones forbidden places such as service stations, security services, army, border patrol and narcotics and customs. In addition, it can also be used as conference rooms, auditoriums, courtrooms, libraries, examination room, schools, cinemas, theaters, museums, hospitals and other places which need to ensure the information is safety.
