GPS jammers are my hobby and the only thing I write about. So trust me when I say they come in all shapes and sizes, I know what I’m talking about. In this article we will discuss output power as it relates to GPS jamming devices.
Output power is a term that you will see next to almost all jammers, and it is worth it with a grain of salt. The more power a device has, the larger the area it can stop the signal from operating. This is called the radius, or how far away from the device one can get to them again before the signal starts to be free of outside interference. Typically, these radii (or ranges) are measured in meters, and the longer the distance, the fewer problems you will have with tracking devices or nuisance navigation signals in your daily life.
1,000 meters. We are talking about a one-kilometer jamming radius. Typically, these jammers can be installed in military facilities to protect against GPS-guided weapon systems.
10 kilometers. In some countries, where tracking devices for military use have been banned, cheap gps jammer are used to prevent them from working.
100 meters. This is the largest common jammer radius we have. It is used in many larger buildings to negate the presence of signals from the ground floor and anywhere below.
The jamming radius of a GPS blocker is proportional to its power output. The signal strength is reduced by the square of the distance from you, so doubling your distance from any signaler reduces its strength by a factor of four. This means that it is easier for you to block a low frequency jammer (1-5 GHz) than a high frequency jammer (5-15 GHz).
A good analogy for what happens when there is a jammer nearby: Imagine if you were standing in front of a speaker at an outdoor concert with a friend about 20 feet away; they could both hear each other clearly and understand what they were saying. Now imagine that there are 100 people between them, and they are all talking loudly; very few words come through clearly now because they are drowned out by all the other sounds around them. This is the basic situation when we have multiple signals around us; they combine into one big mess
10 meters. This is ideal for use in cars where you want to protect yourself from sneaky hackers tracking your car’s location.
10m. This is ideal for use in a car where you want to protect yourself from sneaky hackers tracking the location of your car. It can be used at home or in the office, but it is especially useful if you want to protect yourself from being tracked by a GPS tracking device placed in your car.
Most people will find that 10 meters is the maximum common jammer radius, and this type of power does a good job of negating the presence of signals from anywhere above and below (but not above) the ground.
1 meter. A common choice for a tracker blocking device that fits into a phone case or wallet.
2m. A larger option for those who want to cover more ground and/or want to jam more devices at once.
3m. A larger tracking blocking device that has the potential to cover an entire room or several rooms, depending on how many jammers are being used at once.
4 meters. This is the largest size of most tracking blocking devices, and this size is often used by businesses that want to block signals in large office buildings or warehouses with multiple levels of cubicles.
GPS jammers actually come in all shapes and sizes.
There are even jammers that are designed to fit in your pocket or purse.
While there are many types of jammers, most work by emitting powerful radio frequencies that cause interference with GPS tracking systems and GPS navigation weapon systems such as missiles or drones. The closer you are to the jammer, the more likely you are to experience negative effects such as data loss or signal errors from your device (such as a cell phone). This means that if you want your employees to use their smartphones at work without experiencing any connectivity issues, then installing a jammer near them will help keep everyone connected while preventing others from hacking into the device via cell phone signals
