The company develops and produces communication antennas for use with mobile phone signal shielding devices. Mobile phone signal shielding devices are also known as: shielding devices, mobile phone shielding devices, signal shielding devices, mobile phone signal jammers, mobile phone signal blockers, mobile phone isolators, mobile phones. Chopper, mobile communication signal blocker, mobile phone signal shielding device, mobile phone jammer, signal jammer, mobile phone blocker, signal blocker, mobile phone signal isolator, signal isolator, mobile phone signal interceptor, radio signal blocker .

It is based on the uplink and downlink channels of the mobile phone system, using frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency; customizing a spherical shielding space according to the power of the shielding device, automatically forming a shielding magnetic field within a specified range. Mobile phones (including PHS-PHS GSM-China Unicom, China Mobile, CDMA-China Telecom) are invalidated in this space. When the shielding device is in working state, the function of transmitting and receiving signals of the mobile phone in the specified range is invalid, and it is impossible to dial out and dial in, thereby achieving the purpose of mandatory disabling.

Can be applied to: all kinds of examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military sites, libraries, theaters and other places.

However, in densely populated areas such as schools, it is forbidden to set up radio stations with excessive electromagnetic radiation, and mobile phone signal shielding devices must not be used without authorization.
