Block cell phone cameras - Is it possible to block mobile phone signals in the whole school?

Hi Chad! As I can see from what you have written, the problem is especially acute in your case. You need to cover whole school with blocking signal that will jam 3G, 4G and all GSM and CDMA frequencies. Your choice of the unit to utilize is right because the adjustable five bands desktop jammer RCJ40-D suites your case in the best way. First of all, its frequency bands will be tuned to work with frequencies you need - GSM850 (CDMA800), GSM900, GSM1800 and GSM1900 (DCS, PHS), and 3G. Just don’t forget to choose them during your ordering process. The quantity of 2-3 units per floor should be enough, and if the jamming signal will go beyond the school area, you can use the control knobs to make its output slightly lower for jamming signal to stay inside the school area. As for 4G, you need to use another device - XLG15 4G LoJack jammer. It is not desktop but portable one, so its jamming radius is smaller thus you need 4-6 units to cover each floor. As for WiFi interference, you may not worry about it. If you read the first part of the article about frequencies we jam, you’ll see that GSM band is far from WiFi, and in second part you’ll see that 3G is also far from dangerous range. The only threat for your WiFi network is the 4G signal jammers because its frequencies are really close to the WiFi frequencies. I can advice you to take one XLG15 and test if it will interfere with the WiFi network of your school. If so then there would be two options: leave 4G band for students and staff to use or accept the fact that your smart boards and security cameras will work worse than they should. You know, the problem of students using mobile phones and other personal gadgets in schools is not new but different schools deal with it in a different way. You have decided to block the whole school from mobile devices and maybe it is right thing to do. In any way, I hope my answer will help you to manage this matter successfully! :)
