The US law not only prohibits the purchase, sale, wearing and possession of cell phone jammer, but also published Craigslist advertisements indicating that they are selling cell phone jammers. Human intervention can result in fines of up to $11,000 and up to one year in prison.
The ban on mobile jammers is not new. In fact, this is a moldy old communication law of 1934 that prohibits interference with commercial radio communications, not only in front of jammers, but also in front of mobile phones.
Mobile phone interferometry is different around the world. For example, in the UK and Japan, anyone can have a portable jammer unless they use jammers. Dozens of countries, including Canada, Mexico, New Zealand, Norway, Turkey, etc., allow police and prison officials to use signal jammer.
Schools in China and India use sabotage devices to thwart fraudsters. In Mexico, sabotage devices are allowed in churches and hospitals. Pakistan allows intervention in banks and libraries.
Most countries, including the United States, use jamming devices to prevent cell phone bomb attacks on government leaders. When President Obama walked on Pennsylvania Avenue after taking office, all cell phones in the area were blocked. The U.S. military used a sabotage mechanism to thwart a roadside bomb attack in Iraq.
In fact, strict U.S. interferometric measurements apply to everyone except government officials. This raises the question: is it correct?
American prisons want to use jamming devices. The same applies to the police, but despite this, many movie theaters, restaurants, and other businesses do the same. Some people want to use jammers. Who decides that cell phone jammers can only be trusted by federal officials?
