Nowadays, you are likely to get free WiFi connections no matter where you find yourself: whether a shopping mall, cafes, restaurants, libraries or even some city areas. — these WiFi networks help by keeping you stay connected. Due to open access to Wi-Fi at these places, obviously many people are taking full advantage of this to stay connected even when they do not have anything to offer these places until somebody does something to save these places. The solution we are talking about here is the Wifi jammer!
Jamming devices, according to the FCC, are defined as illegal radio frequency transmitters, which are designed to interfere with, block or jam authorized radio communications such cellular, gps and wifi/bluetooth frequencies, etc. Why jamming technology may be termed illegal? One reason is that it is currently unable to differentiate between desirable and undesirable network communications. For example, a WiFi jammer can disrupt all radio communications available on any device that makes use of radio frequencies for its operation. These devices are affected only if they are in the radius of operation of the jammer. A WiFi signal blocker does this by emitting radio frequency bands which go against that of the targeted device, thus preventing the device from maintaining or even establishing a connection.
Jammer devices also include WiFi jammers and mobile phone jammers which can prevent your cell phone from receiving or making calls, emails, and text messages. Moreover, they can prevent your your WiFi enabled device from getting connected to the internet for several operations, keep you from receiving the exact positioning signals with the use of GPS, and prevent you from getting located by a first responder in an emergency.
Are WiFi jammers legal or not?
The federal law prohibits the use, operation, sale and marketing of any type of jamming device. The prohibited devices include those that interfere with mobile and GPS(Global Positioning Systems), PCS(Personal Communication Services), WiFi(wireless networking services), and police radar. The law is designed to prevent the use of these devices because they know that they pose serious safety risks and may lead to severe accidents. So the use of cell phone jammer is a violation of the federal law,and very soon those who are violating this law will be cracked down by the law enforcement agencies and the enforcement bureau. Since they pose serious risks to the important public safety communications and they can prevent people from calling 9-1-1 and other emergency numbers. –That explains why it is now unlawful to sell, distribute, advertise, or market the jamming equipment to people and consumers in the United States. And finally, the jamming devices can alter the law enforcement communications. Therefore they are doing this through outreach, education, and aggressive enforcement to tackle this problem. In the US, the only legal buyers of such equipment are government employees.
However, the legislation regarding jamming equipment varies from country to country. In the UK and Japan, anyone can own a jammer– as long as they don’t use it.
Also dozens of countries, including Canada, Mexico, New Zealand, Norway, Turkey and others, allow the police or prison officials to use jammers. It is said that Mexico for example allow use of cell phone jammers in public areas such as churches and hospitals.
In Chinese and Indian, schools use jammers to stop cheaters. And Pakistan allows jamming in banks and libraries.
It is worth mentioning that most countries, including the U.S., use jammers to thwart cell-phone-triggered bomb attacks against government leaders. The U.S. military once used jammers to stop roadside bomb attacks in Iraq.
As a conclusion, we should repeat the fact that you definitely need to do the best and check your local laws and before buying a signal jamming device make sure to check the frequencies you need to jam. We are trying to protect you here, so keep in mind that the number one thing that you should do here is to check the laws of your nation and right after proceed to purchase.
