Mobile phone signal jammers are mainly aimed at all kinds of places where the use of mobile phones is prohibited, such as various examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, governments, finance, prisons, public security, and military centers. It is understood that the mobile phone signal jammers on the market can limit the mobile phone signal 500M meters away from the launching station. The radius of the signal shielding can be adjusted independently, and the coverage area is more than 30 square meters. The power of the mobile phone signal shielding device is generally 12W-480W.
Can a mobile phone signal jammer block wifi signals?
High-power cell phone jammer can not only shield mobile phone signals, but also effectively shield WiFi signals, GPS signals, and Beidou satellite signals. Among them, because the working frequency of WiFi and WLAN signals is in the range of 2.4GHZ or 5.8GHZ, if you need to shield WiFi signals, it is recommended that you buy a high-power "Texin Electronics" SYT-G2100 portable 8-channel mobile phone signal jammer.
The mobile phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, mobile phone no signal, no service system and other phenomena.
The portable mobile phone signal jammer adopts imported IC and is independently researched and developed, especially for small venues at home and abroad that require safety and confidentiality, such as confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries guarding the scene, etc. , A high-tech product carefully developed according to the actual situation of mobile communications at home and abroad. It can block GSM/CDMA/DCS/PHS/PCS/3G mobile phone signals within a radius of 0.5-15 meters (usually about 5-80 square meters) (Enhancement can shield WiFi signal, GPS signal, Beidou satellite signal), so that the mobile phone in the area cannot make and receive, and will not interfere with other electronic equipment in the environment. When the mobile phone is far away from the shielding range, normal use can be restored.
