What is the jammer?

Signal jammer is a device that blocks transmission or reception of signals, usually by creating some form of interference at the same frequency ranges that cell phones use. It is created to help people solve different problems coming from cell phones, radio signals and wireless connections. Every kind of it is designed to work with a specific frequency range. Of course, the design of jammer is more and more inclined to comprehensive performance. That means a jammer can block more and more frequencies

This equipment is manufactured to block signals in environments where cell phone activity may not be desirable, such as theaters, churches, classroom, library and operating rooms. Portable personal jammers are available to enable their owners to stop others in their immediate vicinity from using cell phones. It is easy to use and carry. The desktop jammer has better jamming performance and larger jamming range

This kind of device can be divided into frequency, band and function according to jammer attribute categories . You can find the jammer device according to your needs.

At present, this kind of equipment is being used in many fields. It is now used in cinemas, restaurants, cafes, theatres and other places

Why need to use signal blocker

With the progress of science and technology, our lives more and more convenient. But, the same also brings a lot of trouble:

Telephone calls may be eavesdropped, WiFi may be compromised, electronic devices with cameras may be invaded, personal privacy has received a great threat. Not to mention the ubiquitous drone and GPS positioning. In order to protect your personal privacy and communication security, may be you need try using jammers.

Buy a cheap mobile blocker device have become a necessity for accomplishing a more cultured society because there is a growing demand for controlling the use of cellular phones in public places such as religious places, theaters, libraries, and others.

With the popularity of smart devices, in addition to the above notice places, some other places also need this equipment

There's no question that in most offices, email and the Internet are absolute necessities. But are cell phones? In a survey by Pew Research, only 24 percent of adults with full- or part-time jobs listed a cell or smartphone as "very important" to getting their work done. In other research, 50 percent of bosses think a cell phone is a negative to workplace productivity.

Just as a parent has the ability and right to cut off the Wi-Fi at home, they should have the option to cut the cellular signal if desired. Grabbing phones from hands to put them in airplane mode probably won't work, and making the house into a Faraday cage is an extreme only the tin-foil hat crowd should try. But an in-home cell phone jammer should be an option whenever desired or necessary.

However, in the United States, if you own a car, this device is also required. Why say so? For two reasons. The first reason is GPS tracking. As GPS trackers become more available in the United States, you never know when you're being tracked. The second reason is driving safety. As we all know, young people nowadays can't live without their mobile phones. It's not hard to imagine them using it while driving. This is very dangerous!!! So we need a jammer to prevent them from using mobile phones

In addition to the above devices, the anti-tracking jammer is also very necessary. Now, because GPS tracking devices are so easy to buy, they're easy to install on a car. At this time, GPS backtracking jammers are required.

Of course, as drones proliferate, more and more organizations and individuals need to use drone jammers to manage them.
