Whether the whole school can block mobile phone signals

Our concern is two-fold: First, we cannot block WIFI as many school services use wifi bands as data transport (smart boards, security cameras, etc.). Second, as the building is ATTACHED to other buildings we want to minimize bleed into neighbors. Finally, we want to make sure that when power is lost – and then restored – the units ‘remember’ their state; i.e. either on or off, and recover to the same state.

Looking at your various units available, very few detail the frequency range that is blocked. I.e. they just say 3G… As 3G and wifi are close… we need to make sure that we don’t block wifi – so we’re fearful of say the MGT40 (to 2500!!),. It seems that the RCJ40-D might be the right unit to utilize?

This principal did not even bother the phones all day, just during class. Not only that, schools have rules against the use of cell phones at school, especially during classes. What worries me is that cheating could reach a whole new level as children could transmit the answers to each other by text message. Not only that, teasing and gossip could become the priority rather than learning. Are teasing and gossiping bad enough in high schools without texting during class?

The fight between teachers and students on the use of mobile phones in schools has reached a new level in British Columbia. when a school principal has installed a cell phone jammer to stop ringtones, speech and text messaging.

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
