Whether it's ringing in an ongoing class or watching a wonderful show in the theater, the use of mobile phones can be very distressing to those around you.Portable jammers are the most popular type of all signal interference products.Using a mobile phone near a gas station is even more dangerous and can even cause an explosion,which seriously affects life safety.Some dangerous elements conduct remote monitoring during confidential meetings until a remote bomb is triggered.Signal jamming equipment varies by type. For these, the signal blocker can have a strong interference result.

In recent years, the continuous development of advanced technology, especially the constant replacement and update of mobile phones, has completely changed our communication methods and daily life. At present, mobile phones have been widely used, and the frequency bands used by mobile phones mainly include GSM, CDMA, DCS and PCS. Now, with the rapid development of high 3G 4G signals, 5G is also gradually entering the market, and I believe that it will develop rapidly around the world in the near future.They are easy to use and transport, and are much cheaper than jammers with high power and long interference distances.

Mobile phones bring us comfortable and convenient communication, but we regret that some people have transferred these technologies from their main functions and used them in other fields, even committing uncivilization or even more serious, malicious or horrible behavior.
