they put a force field type thing around an area. there are different ones with different reaches such as 50 ft. or 75 ft.. but they block the signals cell phones and other devices send and use. so that they do not work

They basically jam signals so cell phones can’t work. There was an article in the paper about them the other day. They are illegal but I guess people can buy them online. I have heard that in upscale restaurants and things like that they often place cell phone jammers so people can enjoy there meals without others cell phones going off.
Devices that transmit static on the the same wavelengths as cell phones signals therefore not allowing anyone use there cellphone. Current used in Iraq and other military security zones around the world.
