GSM Jammer

In modern society, mobile phone signals are everywhere. You can hear the sound of mobile phone signals everywhere, and you are always connected to the Internet. But have you ever thought that some places are not very welcoming to mobile phone signals? At this time, the GSM jammer is like a calm security guard, blocking all the “signals” that should not come in!

First of all, what is the GSM signal?

Simply put, GSM is the hero behind the scenes that allows you to make calls and send text messages with your mobile phone. Its full name is “Global System for Mobile Communications”. Does it sound a bit like Superman? It mainly works on the two frequency bands of 900 MHz and 1800 MHz, relying on a technology called “Time Division Multiple Access (TDMA)” to allow everyone to make calls at the same time without interrupting each other.

Of course, its greatest ability is: clear calls, strong anti-interference, and the ability to send text messages and transmit data. Even many smart devices cannot do without it. It is not an exaggeration to say that it is the “Big Brother” in the communications industry.

However, sometimes we really don’t need GSM signals!

At this time, GSM jammers come on the scene! The function of GSM signal jammers is very simple – they imitate the frequency band where GSM signals are located, emit “interference waves”, and turn the mobile phone into a “brick” instantly, making it unable to receive or send information. In fact, GSM jammers are more useful than you think!

Which scenarios need GSM jammers the most?

• Examination room: the ultimate tool to prevent cheating in exams
  Imagine that a candidate takes out his mobile phone to search for answers and is about to send a message, but suddenly the signal disappears. At this moment, his mobile phone only has one function left: to check the time. That’s right, this is the magic of GSM jammers.
• Business meetings: ideal tools to prevent information leakage
  You worked hard for a year to prepare a business plan, but it was secretly broadcast live? Don’t worry, with a GSM jammer, the conference room instantly becomes a “signal blind spot”, and secretly filming, recording, and live broadcasting are all ineffective. Want to distract yourself with your mobile phone? Sorry, there is no signal.
• Hospital: The quiet power that protects life
  In the operating room, any little interference may affect the stable operation of medical equipment. The GSM jammer is like a quiet guardian, blocking GSM signals that may interfere with the patient. The doctor is at ease, the patient is at ease, and the operation goes smoothly.

Although the 5G era has arrived, GSM signals still play an irreplaceable role in the fields of Internet of Things, industrial control, remote monitoring, etc. GSM signals are economical, stable and reliable, and are still an evergreen in the communications industry.

You need to know which signal bands you need to interfere with. If you only need to interfere with GSM signals, then buy a device that only interferes with GSM signals. However, since most places now need to interfere with several different signals, we recommend that you buy multi-band jammers, such as CJM28PT01, CJM10DT03, CJM24PT01, CJM16PT01, and CJM08PT02.
