What Is A Cell Phone Jammer?


Cell phones have become a major part of our lives. From receiving all of our calls to accessing the internet, they have become essential. In this brief blog post, I will tell you what is a cell phone jammer and I will explain how it works.

What Are Cell Phone Jammers Used For?

A cell phone jammer is a device that blocks the reception of signals. This is done by creating some type of interference at the same frequency ranges that cell phones use.


When this happens a cell phone user will experience a significant loss of signal quality or completely lose their signal.


In basic terms, a cell phone jammer works by sending out so many signals that it makes it impossible for cell phones in the area to connect to towers.


The communication blackout works both ways, from the tower to the phone and from the phone to the tower. Cell phone jammers will work just about anywhere you want to use them.


A cell phone jammer works only as well as the device that is used. The more power that is put into the jammer, the more effective it becomes and the range becomes longer as well.


Additionally, better antennas can further propagate the signal jamming.

Cell phones work on a variety of frequencies. To eliminate access to all providers you will have to target all frequencies. This can be done in two ways.


One way is to have a cell phone jammer that can emit multiple frequencies when tuned to specific networks such as AT&T or Verizon.


This is often the best way to use a cell phone jammer as it will allow you to still access certain networks. You can fine tune it to your needs. There is less interference when using this method.


Another way to jam frequencies is to emit such a strong signal from the cell phone jammer to kill everything in the area. Using this method will cut off just about any kind of radio signal in the area.


An important thing to note is that cell phones from different countries will also operate on different frequencies. Cell phone companies for the countries, along with the local radio authorities decide the spectrum for cell phones.


This means that a cell phone jammer that is designed for one country, might not work in another country unless it blocks all signals.


Interference Emission:


The idea behind a cell phone jammer is to interfere with cell phone signals. To do this it sends out a powerful signal.


Signals sent out from the cell phone jammer are not as fine-tuned as other radio devices. You must make sure that a cell phone signal does not bypass the signal from the cell phone jammer.


Unfortunately, this powerful signal will interfere with other radios in the area. So many different types of technology rely on radio frequencies.


From landlines to wireless networks and even law enforcement radios. When you use a cell phone jammer, you will end up blocking signals that you don’t want to block.


Are Cell Phone Jammers Legal?

In almost all circumstances using a cell phone jammer or any kind of signal jammer is illegal. This isn’t just in the United States.


Other countries around the world have banned these devices as well. One of the major reasons behind banning these devices is that they interfere with other devices that they aren’t intended to target.


Another reason is due to safety concerns. Since most locations no longer have landlines, if cell phones were disabled, you wouldn’t be able to call for help in the event of an emergency.


Likewise, law enforcement might not be able to communicate upon arrival as their signals might also be blocked.


In the United States and many other countries around the world, there are exemptions made to the banning of cell phone jammers. These exemptions are mainly for law enforcement agencies.

A cell phone jammer can be essential when trying to stop a terror attack or prevent criminal agencies from communicating.


Most cases of cell phone jammers will need approval from a chief law enforcement officer or a judge, depending on the jurisdiction.


Despite being illegal, it is incredibly easy to purchase a cell phone jammer. The internet has an abundance of devices to choose from.


There are also instructions on the internet for making your own cell phone jammer.


Cell phones can be annoying but turning to a cell phone jammer in anything but an emergency could leave you in big trouble.


The FCC banned the use of any device that blocks authorized radio traffic. In fact, multiple people from teachers to commuters have gotten in trouble for using cell phone jammers to block other people’s cell phone signals.
