The mobile phone jammer is 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 , theaters, hospitals, governments, finance, prisons, public security and military centers.
At present, the mobile phone jammer can limit mobile phone signals that are 500M meters away from the launching station and have a radius greater than 20 meters. The shielding radius is adjustable, it only shields the mobile phone signal without affecting other electronic devices.
The mobile phone works within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission are completed with a certain baud rate and modulation method. In view of this communication principle, the mobile phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process.It 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, no signal, no service system and other phenomena.
The working frequencies of common mobile phone jammers are 869~894MHz, 825~960MHz, 1805~1880MHz and 1900~1990MHz.
