As the sales of drones are expected to grow exponentially in the near future, the number of drone events that occur every day is increasing, and the harm it brings is also increasing. Some experts have launched to address the malicious use of consumer and commercial drones. drone killer is designed to help public and private sector clients take proactive measures to prevent airborne threats to safety, security and privacy.
So will interfere with other electronic software? The jammer is designed to disrupt the drone by transmitting electromagnetic noise at radio frequencies, thereby intercepting any communication channel between the drone and its controller, which interferes with the "unallocated" public frequency WiFi 2.4Ghz or 5.8Ghz ("RF interference "). This means that UAV blocker will not interfere with manned aircraft, cell phones, public broadcasts or other dedicated radio bands.
In addition to legitimate RF interference to users, GPS interference can also be utilized because a large number of drones rely on GPS to move between predetermined waypoints. When a drone signal is hit by the UAV jammer, the drone usually returns to its origin, and sometimes even falls vertically and falls intact. When the (RF and GPS signals) are simultaneously truncated, the landing of the aircraft is a common reaction of the drone.
With the popularization of smart phones, wireless networks occupy an increasingly important position in people's lives. People can use the wireless network to browse the web faster, watch videos, and download apps.

If you want to block all WiFi signals, or just want to kick someone out of the WiFi throne, you only need a .
The jammer is extremely small and weighs only 0.29 kg. It can be carried in a pocket, carried around, and equipped with a DC charger that can be recharged at any time. Although the volume is so small, its jamming radius is up to 10 meters, and it can block signals such as GSM 3G GPS at the same time. It can work continuously for two hours with a full charge and is equipped with a car charger. It is currently the best-selling on the market.
This is only mobile phone size, easy to hide, can be put into your pocket at any time, generally suitable for outdoor use, and can shield GPS positioning to prevent being tracked. Stable work, much cheaper than other products of the same model, but please ensure that it is used for legal purposes (such as educational purposes), not illegal.
The mobile phone signal shielding device is also called . Its working principle is: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound are transmitted with a certa...
