I can not admit that sometimes you have to use illegal means to prevent the use of some signals, similar to the invigilator in the examination room, this time we need to use a Cell Phone Blocker
I'm curious how much can the Jammer shielding in the end range, is not there can be 1 km away, it would be too crazy
Phone signal is not really the radiation, I think cell phone signal jammer can give you the answer, you try to know, huh.
I can not say that some parts of the hotel is equipped with hidden surveillance cameras, peeping my privacy, so sometimes Wifi Jammer is quite useless
In my neighborhood there is no cell phone signal jammers to sell?
I know a place, but not in your neighborhood, they sell worldwide mobile phone jammer.
