What is a Mobile Phone Jammer?

Smartphones are a major influence on the lives of everyone on this planet. Cell phones are a popular and widely used method of communication that is used by over a billion people around the world. Smartphones have many benefits, but there are also disadvantages. Signal jammer, (brouilleur d’onde) is a designed to block all signal transmission to prevent people using mobile phone, GPS, or Wifi.

How Does a Jammer Work?

A cell phone jammer is a device that blocks mobile phone networks. It prevents the phone from communicating with nearby cell towers. The mobile phone jammer will disable a cell phone’s signal by emitting stronger frequencies and causing it to become a “dead zone”. Since the cell phone’s reception is completely dead, the user will no longer be able to receive or make phone calls.

To give you a better understanding of how a signal jammer works, you can imagine that you are talking with your friend during a rock concert. Apparently, your friend can’t hear what you say because the music covers the voice signal sent from you. A jammer works similarly; it will general a lot of white noise signals to interfere with the data transmission between the receipt and sender.

To completely prevent people from communicating with each other, today’s signal jammers usually come with a wifi blocking function, also known as wifi jammer or brouilleur wifi. You can tell by its name; it’s used to block wifi signals to disable internet access; that way, no one can log in to their Facebook, email, WhatsApp, etc.

Why Do You Need a Mobile Phone Jammer?

Cell phone jammers are widely used in places where using a mobile phone could cause a problem. For example, gas stations, schools, theatres, restaurants and workplaces, and classrooms. It is unnecessary to mention that teenagers now have the latest smartphones, which can interfere with lessons and disturb other students. Jammers could also be used in religious places such as churches, synagogues, temples, and masjids. 

Additionally, governments around the globe have been installing such devices in prisons or other sensitive areas.

Always remember that jamming devices should be used with caution. Although it may be irritating to listen to strangers talking on their phones for the entire bus ride, it is worth thinking about what you are doing.

The Jamming Range

Understanding the specifications before buying a signal jammer can help you make a better decision. The jamming range is one of the most important factors you should consider when buying a jammer online.

The jamming range is a number indicating the size of the area a jammer can cover, or you can think the jamming range means how large a signal “dead zone” can be created by one jammer. In most cases, it can range from 15 meters to 80 meters. Some jammers designed to block drones can reach 500 meters, and military jammers can cover an entire football field.

The output power, antennas, and cooling system impact the jamming range. Those factors also impact the overall performance and durability of a jammer. 

A signal blocker with an output power of 15W or less will perform better than an 8W. Directional antennas have a greater jamming radius than regular ones because they only focus all of their output power in one direction. High-quality cooling fans also prevent jammers from overheating. This allows jammers to last longer in terms of both performance and longevity.
