With the improvement of technology, various mobile phones have appeared one after another, which brings great convenience to people’s daily life and also brings a lot of entertainment to our leisure time. Therefore, more and more people cannot do without phone interference. Device. Therefore, the phone can always be seen in front of us when and where. However, in some places where the use of mobile phones is not allowed, continuous calls will only cause worry and generate a lot of noise interference, which requires mobile phone jammers to restore peace in our area.
Bennington cited several examples of GPS interference/jamming in recent years. This includes the Eastern Mediterranean earlier this year, where five ocean-going ships and one aircraft were disrupted for a long time, some with a range of up to 25 miles. Last year, GPS was blocked by Russia in Norway for a week. In the second quarter of 2016, more than 50 reports of GPS interference on Manila International Airport’s approach to Runway 24 resulted in the loss of onboard GNSS function, invalid GPS-L and GPS-R messages, and reduced navigation. Performance causes RNP alarms. This also led to the omission of the method Bennington said that the “Pokemon Go” augmented reality application launched in 2016 encouraged hackers to cheat GPS to win prizes and upload codes. “Most of the spoofing they do is done on mobile phones, but you need to use the same code and software-defined radio and pair it with location and timing data. So you can create a GPS or GNSS spoofing device. He said .
The latest report of the Russian independent media group “Project” investigating luxury villas owned by senior government officials shows that most of the equipment includes cell phone jammer. Reporters try to use drones to photograph dashes from the air, but they usually fail. Most military and security services in a country have equipment that can block GPS and other satellite navigation signals in areas of all sizes. However, Russia has developed it into a regularly exhibited art.
Used for jammers for WIFI or BLUETOOTH and wireless cameras. The purpose of wifi jammers is to avoid communication equipment based on 2.4 GHz folk frequency band communication, although there are 5.6/5 frequency bands, 8 GHz, and more and more after the 2.4 GHz frequency band is saturated To use. These frequencies cover almost all household devices, such as phones, computers, routers, set-top boxes, wireless microphones, most miniature cameras and spy equipment, etc. The walkie-talkie is a jammer that focuses on the frequency of the walkie-talkie because it is a widely used device, very cheap, and not (directly) controlled by the telephone operator. In turn by the government) and often used for criminal purposes. Used for remote activation of workpieces.
