Cell phone jammers block non-cellular communications

Perfectjammer 2021/04/28

Portable cell phone jammer, also known as signal scrambling blockers, provide the best solution in areas where cellular communications are generally unpopular. It will stop the signal transmission between the cell phone and the cell tower. The cellular phone signal blocks the interfering mobile phone by sending radio waves that use the same frequency as the phone. When you turn on the mobile phone signal jammer, all mobile phones in the area will be prompted "No Service". You don’t have to worry about other electronic devices, as this will not affect non-cellular communications. This will only interfere with the signal of the mobile phone, will not interfere with the normal use of other electronic devices, and will not cause harm to the human body itself.

1. First, you need to know the network frequency in your area. In Africa, Europe, the Middle East and Asia, most regions use the 900MHz and 1800 MHz frequency bands. Therefore, when buying a mobile phone jammer, you need to consider this spectrum.

2. Make sure you understand the local communication service provider. In the United States, the largest suppliers are 3G, 4G, CDMA and GSM. Before buying a mobile signal jammer, you should first check it over the Internet, which will provide you with complete information about the Verizon frequency in your area.

3. Determine the required interference range and application purpose. For a small area like a classroom, it's small and portable. However, if you want to use it in a theater center with a capacity of 10,000 seats, you must purchase a large number of interference jammers for telephone signals.
