The radiation of a signal GPS jammer
The signal has a certain degree of radiation to the human body. Like signals, GPS jammers radiate. Both electromagnetic radiation intensity is less than or equal to 75dBuv, and the radiation is not big.
Gps signal jammer has no effect on the human body. The signal GPS jammer is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, government, finance, prisons, public security, military centers, etc. A forbidden place.
It is understood that the signal GPS jammer on the market can limit the signal within 500m of the transmitter. The shielding radius is adjustable, and the coverage can reach more than 30 square meters. Gps signal jammer can only shield signals and does not affect other electronic devices. Power saving, power 12W-480W.
Brief Introduction and basic principle of signal GPS jammer
It uses frequency multiplication, frequency division, frequency hopping filtering, and other technologies to analyze the required shielding frequency for the upstream and downstream channels of the system; customizes a spherical shielding space according to the power of the GPS jammer, and automatically forms a shielding magnetic field within the specified range So that mobile phones fail in this space.
When the GPS jammer is in a working state, it can disable the function of sending and receiving signals of mobile phones within the specified range, and cannot dial out or dial in, so as to achieve the purpose of mandatory disabling.
It can be used in various examination rooms, conference rooms, gas stations, oil depots, churches, hospitals, courts, military centers, 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 without permission, it is forbidden to use GPS signal jammers.
The GPS jammer scans from the low frequency to the high frequency of the forward channel at a rate during operation. The scanning speed may cause aliasing interference in the received message signal, fail to detect normal data transmitted from the base station and fail to establish a connection with the base station. It displays for search network, no signal, no service system, and so on.
According to the development of mobile communication systems, the third generation 5G signal GPS jammer is developed. The difference between a GPS jammer and a common signal GPS jammer is that it can not only shield common signals but also completely cover the frequency band of mobile communication operators.
