A high-power signal blocker is a device that can block or interfere with wireless signals in a specific frequency band, and it can be used to protect important places, people and equipment from interference or threats of wireless signals. Its working principle is to use high-frequency electromagnetic waves to emit powerful noise signals to the designated area, so that the wireless communication equipment in the target area can not receive or send signals normally, so as to achieve the effect of shielding or interference.
High power signal blockers have many functional features
Different frequency bands and output power can be selected according to needs to achieve flexible shielding range and effect.
It can simultaneously shield multiple frequency bands, such as 2G, 3G, 4G, 5G, GPS, WIFI, etc., to cover a variety of wireless communication systems.
It can be used in different forms such as vehicle-mounted, portable and fixed to adapt to different occasions and needs.
It can have intelligent control functions, such as timing switch, remote control, etc., to facilitate user operation and management.
It can have heat dissipation system and protection circuit to ensure stable and reliable operation of equipment.
Application scenarios of high-power signal blockers
Prevent the leakage of important information: The use of blockers in government agencies, military bases, business negotiations and other places can effectively prevent mobile phone photography and recording, eavesdropping and theft.
Maintain public order: The use of blockers in public places such as theaters, theaters and libraries can effectively avoid disturbing others with mobile phone ringtones.
Ensure safety prevention: The use of high-power shields in flammable and explosive or sensitive equipment places such as gas stations, chemical plants, hospitals can effectively prevent mobile phones from causing fire and explosion or interfering with the normal operation of instruments.
Blocking illegal communications: The use of blockers in prisons, detention centers and other custodial places can prevent criminals from illegally communicating with the outside world.
Ensure the fairness and justice of the examination room: The use of a shield in important test places can make mobile phones, telephones, wireless wifi can not be played and answered, and can not send or accept SMS, so as to ensure the safety of the examination room.
