In this Internet age, everyone has their own mobile phones and other communication devices, which brings a lot of convenience to everyone's life. However, in some special areas, mobile phones and other communication devices have brought a lot of troubles to people, such as: conference rooms, examination rooms, schools, dormitories and other areas, all of which have encountered similar problems. At this time, we can use signal shielding instruments, which can effectively block and interfere with the signals of mobile phones and other communication devices, and help special areas solve such problems. So do you really understand what signal shielding instruments are? Let's take a look at the main problems of common signal shielding instruments.

1. What is a signal shielding instrument

The signal shielding instrument uses a mobile phone to receive mobile signals sent by a base station, which interferes with the communication device of the mobile phone signal and the communication base station. These equipment research and development designs are mainly used in conference rooms, examination rooms, schools, dormitories and other areas where mobile signals need to be shielded. After starting, they can deal with threats that affect information security such as mobile phone signals, electromagnetic signals, and base station signals.

2. How does the signal shielding instrument work?

The signal shielding instrument can effectively interfere with the radio frequency in the area, blocking the mobile phone from receiving information, and thus interfere with all communications in the area. The wireless signal is actually like a noise-cancelling bubble. The user's phone will directly lose the ability to send and receive calls or text messages as long as he is within the range of the signal jammer for cell phone. The ability to receive calls or text messages will be restored after leaving the shielding signal range.

3. So why use a signal jammer?

Proponents of this technology believe that signal jammers are necessary when we cannot follow the generally accepted correct mobile phone standards. Think about the conference room, examination room, school, dormitory, or other quiet train. Most conversations, text messages, and streaming media can be destructive or even terrible.

Remember that signal jammers will not only block the audio and text on your phone, but also interfere with GPS, radar detection, and police equipment radar detection, which may cause more serious problems. For this reason, the US federal government prohibits the sale and promotion of signal jammers in the US market. So if you want to bring some peace and quiet with a shiny new signal jammer, you may just have to settle for headphones.

4. How should the jammer be tested?

You guessed it, the most common symptom of a signal jammer is service interruption. While some apps claim to detect jammers, most of them are unverified and require a working signal to work. Without any advanced military technology, it is virtually impossible for the average user to detect jammers on their phone.

5. How to prevent noise interference?

Blocking jammers is not an effective method unless you can actually find the jammer itself (usually looks like a walkie-talkie, cell phone, or wireless landline) and disable it.

Assuming you are technically proficient and can switch the power of your phone, you can also try jammers. But it does rely on the jammer to block complex signals.

If you suspect you will be the victim of a jammer attack, get away. Jammers usually have a range of no more than 300 square meters, so moving away from your current location is usually enough to avoid it.
