Legitimacy of global signal jammer
Techniques that deliberately interfere with electromagnetic frequencies (also known as interference) have been implemented in various devices, which are gradually provided to individuals and organizations. The interference is becoming smaller, more convenient, easier to use and cheaper, although in fact in most countries in the world, the interferencer is illegal. Although certain interferencers will block communication without differentials, there are several dedicated devices that are specifically designed to prevent certain signals. Among them, the most popular is the mobile phone jammer, WiFi interference, drone jammer , and even GPS interference. In most countries, the authorities mostly disapproving the use of these devices is that they tend to have a greater impact than expected.
