cell phone signal blocker explained

The mobile phone signal blocker is mainly used in various test venues, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, governments, finance, prisons, public security, military places and other places that prohibit the use of mobile phones. It is understood that the mobile phone signal blocker on the market can limit the mobile phone signal from the launch pad 500M meters. The shielding radius can be adjusted, and the coverage area can reach more than 30 square meters. cell phone jammer can only shield the mobile phone signal without affecting other electronic equipment. Save electricity, power is 12W--480W.

The mobile phone masker scans from the low-end frequency of the forward channel to the high-end at a certain speed during the work process. The scanning speed can form garbled interference in the signal received by the mobile phone, and the mobile phone cannot detect normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. Mobile phones appear to search the Internet, mobile phones have no signal, no service system and other phenomena.

The machine is easy to carry and conceal, small in size, light in weight, and weighs only 150 grams; wifi jammer, low power consumption, only 0.5W / h, and use time of up to 2-3 hours; easy to charge, most Nokia chargers are It can be used universally; it is a truly environmentally friendly handheld shield.

gps jammer development of communication standards, the third-generation 3G mobile phone signal shield was successfully developed according to the actual situation of foreign mobile communications. This masker is different from ordinary mobile phone signal shielders in that it can not only shield ordinary mobile phone signals, but also must completely cover the three frequency bands of three domestic mobile communication operators. China Mobile, China Mobile, China Unicom and China Telecom use the following 3G frequency bands: China Mobile 3G frequency band (2010-2025MHz), China Telecom 3G frequency band (2110-2125MHz), China Unicom 3G frequency band (2130- 2145MHz). 5 antennas, 5 channel transmission.

Mobile phone signal blocker is also known as: blocker, mobile phone blocker, signal blocker, mobile phone signal jammer, mobile phone signal blocker, mobile phone isolator, mobile phone interceptor, mobile communication signal blocker, mobile phone signal blocker, mobile phone interference Device, signal jammer, cell phone blocker, signal blocker, cell phone signal isolator, signal isolator, cell phone signal interceptor, radio signal blocker.

high power jammer, it uses octave, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency; customize a spherical shielding space according to the power of the shield, and automatically form a shielding magnetic field within the specified range. Disable mobile phones (including PHS-PHS-GSM-China Unicom, China Mobile, CDMA-China Telecom) in this space. When the shield is in the working state, it can disable the function of transmitting and receiving signals for mobile phones within the specified range, and it is impossible to dial out and dial in, thereby achieving the purpose of forcibly disabling.
