Handheld 5g jammer

A mobile phone jammer that suppresses communication with a mobile phone or the like emits interfering radio waves in the same frequency band as the frequency band used by the mobile phone or PHS, and worsens the radio wave condition received by the mobile phone. It is to prevent the use of mobile phones in the surrounding area. Detailed introduction to WiFi jammers Disable eavesdropping devices and SIM eavesdropping devices that use mobile terminals (including smartphones and iphones). Even if eavesdropping devices using mobile phone terminals (including smartphones and iPhones) or SIM card eavesdropping devices are installed indoors or in cars, it will block communications (outside the service area/interference) to prevent eavesdropping. By sending a high-power radio frequency signal within the same range as the mobile phone communication signal that needs to be shielded, it may cause interference to the mobile phone communication (in a specific area). This wifi jammer can be used to select a series of cutoff frequencies and selectively block only these frequencies. It can be used to prevent GSM, CDMA, 3G/4G and other popular mobile standards from working.
