A signal jammer is an electronic device that blocks the signals that mobile phones and internet use sends out. It is a great tool for students to protect themselves during exams by preventing cheating. The device works by blocking signals for at least 500 meters away from the transmitting station, so it can prevent cheating while still allowing normal use of cell phones and internet after the exam is finished. Here are some tips to choose a telejammer shop.

Firstly, you need to know the frequency bands that are being used for communication in the United States. These bands are GSM850, GSM1900, 3G (850/1900 and 1700/2100), and 4G (Verizon USA 4G, Sprint Clearwire WiMAX, T-Mobile 4G). These bands are commonly used by people to use their cell phones. However, there are some exceptions that you must follow if you plan to use your signal jammer at a public place.

Cell phones are a major distraction at school. Students use their phones to cheat on exams and conduct private conversations. To avoid such distractions, schools use signal jammers to prevent cell phone use during school hours. Other locations where silence is essential include prisons. Prison cell phone jammers will only work inside prisons and won’t disrupt commercial signals. It is important to note that each type of signal jammer has a particular range of applications.
