If that won’t work – that portable Wi-Fi jammer will fit your needs perfectly. First of all it is portable, so you’ll be able to keep it with you. Another benefit here is the jamming range – it is 15 meters, or 50 feet.

All of our Bluetooth jammers block GSM too, but you will be able to turn that function of with a simple DIP switch at the side of the device. The device, we at Jammer-Store have recommended has a battery and it may power it for 2-2.5 hours – that should probably be enough for one test or exam. Don’t forget to turn all the other DIP switches off, or you will block all communications in the area!
