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. 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 (eavesdropping) during confidential meetings until a remote bomb is triggered. For these, the signal jammer can have a strong interference result.
Signal jamming equipment varies by type. Portable jammers are the most popular type of all signal interference products. They are easy to use and transport, and are much cheaper than jammers with high power and long interference distances. The price of portable signal blockers is generally around several hundred dollars And the interference frequency range is diverse, which can generally meet our needs.
Some people will ask, is the jammer harmful to human body and mobile phone? Users can rest assured at this point. The signal strength of the electromagnetic wave signal sent by the signal blocker is very low, which will not cause harm to the human body. At the same time, the mobile phone signal jammer will only block the front signal of the phone, so the phone cannot contact the base station, so it will not cause damage to the phone itself.
