Why does the us need the most advanced jamming technology

That’s why the US needs “penetrating” cell phone jammer, Bacon said: stealth aircraft that are harder – though hardly impossible – to target and which can slip into enemy airspace to conduct electronic warfare at shorter ranges. GPS denial is a becoming a huge issue for American military planners. Peer states, especially Russia, are already putting GPS spoofing and jamming tactics to work during various training events near their own borders. We have discussed this situation in great depth before, and I would suggest you read this article to understand just how deeply the loss of reliable global positioning system data can mean for the U.S. and its allies during a time of war, as well as what is being done to overcome such a monumental hurdle.

In the information age, mobile phones seem to have become a necessity for life, and nowadays it is not uncommon for students to bring mobile phones to school. Although small and medium-sized schools around the world are not allowed to carry mobile phones while they are in school, the phenomenon has repeatedly been banned. In recent days, a high school in the provincial capital has been forced to turn off the lights in the evening and turn on the “high-tech” — mobile phone screening device. I didn’t think that the kind act attracted some parents’ complaints. One was that they were afraid that the screening instrument was not good for the students’ health, and the other was that they would lose contact in the middle of the night. The school was forced to stop using mobile phone shielding.

As long as it is electronic signal jammer have radiation, as for the radiation shielding device, slightly larger than the cell phone, routers, but choose normal manufacturer’s products, through the national multiple departments detection, conforms to the national radiation protection sign value, there is no impact on the human body. The radiation is less than 40 microwatts per square centimeter and is safe.

When the phone works, it is within a certain frequency range. The cell phone and the base station are connected by radio waves, and the data and sound transmission can be completed by certain baud rate and modulation mode. For this kind of communication principle, the mobile phone signal shield is at a certain speed in the working process to the high end of the channel to the high-end scanning. The scanning speed can be used to generate random interference in the receiver’s signal. The phone can’t detect the normal data from the base station, and the cell phone cannot be connected to the base station. Mobile phone performance is search network, no signal, no service system and other phenomena.

The common cell phone signal shield in the market, its function frequency is: 869~894MHz; 825 ~ 960 MHZ; 1805~1880MHz and 1900~1990MHz etc. The frequency band is CDMA800, GSM900, DCS1800, PCS1900. Can control the range of 40 meters in diameter, using DC-DC converter input voltage, 5V output voltage.
