Can jammers block the Bluetooth frequency band?
Cheating exams is a real problem and we will try our best to help you. First of all, you should know that these devices cannot be used without a smartphone. They are of course widely used, but not everyone can afford to cheat. Before trying any drastic methods-try to talk to people and explain to them that using these Bluetooth headsets will make their smartphones vulnerable to attackers, as the 2.4 GHz frequency is quite vulnerable.
If this does not work, then this portable Bluetooth/wifi jammer will be perfect for your needs. First, it is portable, so you can take it with you. Another advantage here is the interference range-15 meters or 50 feet. The only problem here is that Wi-Fi and Bluetooth use the same frequency, so when the interfering device is on all Wi-Fi networks in the area, it will also drop.
All of our Bluetooth jammers can block GSM, but you can activate this feature with a simple DIP switch on the side of the device. The device we recommend to Perfectjammer comes with a battery and can power the battery for 2-2.5 hours-which may be sufficient for a test or exam. Remember to turn off all other DIP switches, otherwise all communications in this area will be blocked!
