A portable signal jammer is a compact and portable device. It has the ability to emit electromagnetic waves of specific frequencies to interfere or block radio communication signals. This type of device is typically used to protect information security, prevent illegal communication, or respond to emergency situations in specific situations.

operational principle

Portable signal jammers interfere or block normal radio communication by emitting electromagnetic waves of the same or similar frequency as communication devices. When these interference signals are mixed with communication signals, it can lead to a decrease in communication quality and even complete interruption of communication connections.
