Whilst evading such jamming is easily possible and having an autopilot likewise, are they currently built into the available drones in a way that can not be overridden by a jamming system who’s manufacture has shall we say a not publicly known arrangement with the drone manufacturer?
Simply pushing lots of CW power into the ether is the most inefficient method of jamming and rarely used because of this. More efficient is a tailored jamming system that is modulated in a way that causes problems in the demodulator of the receiver being jammed, usually by using a high peek pulse power at a critical frequency to the receiver demodulation. Even more efficient is to mess with the stages beyond the receiver such as sending valid modulation that mucks up the computer data processing.
This can be done with the kind of Wi-Fi RF cell phone jammer that is sold to military and government groups. These Wi-Fi jammers will stop most, if not all, hobbyist, commercial and unsophisticated terrorist drones and cause them to return to where they launched with very little chance of doing much more than interfering with people’s Wi-Fi connection in the very near vicinity.
If after activating the Wi-Fi jammer the drone continues toward the stadium, then there is a very high probability of a serious threat. The next stage would be to activate a GPS signal jammer that jams the GPS receiver on the drone. However, a GPS jammer will also interfere with cell tower and emergency communications, and should only be used if the Wi-Fi jammer is ineffective. This technology is already available and in use by approved organizations.
South Korean government officials report that the jamming operation, which began in late March, has been targeting aircraft navigation equipment. North Korea has reportedly broadcast a jamming signal on 100 occasions. A total of 962 planes have been affected by the jamming, as well as nearly 700 fishing vessels. The jamming has also affected cell phone base stations.
The above-mentioned health risks prove that cell phone radiations are injurious to health. Therefore, use cellphone jammers to minimize the bad effects of a cellphone. Usually, children are in the developing stage of their lives. Therefore, exposing to a cellphone in the initial stage can greatly affect their mental as well as physical health. Hence, it is advised to use mobile network jammer. These jammers will protect children from harmful rays and help them to grow in a healthy way.
