The drone 4G jammer can shut down signals at 433MHz, 915MHz, 2.4GHz, and 5.8GHz RF bands simultaneously, ensuring it covers all the most common signal frequencies drones use for communication, with the option to also create GNSS disruption (basically, GPS and GLONASS won’t work correctly). With the signal shut down, any drone in the vicinity will be forced to land on the spot or return back to its starting point, depending on how its internal algorithms are set up, giving folks the ability to retrieve it for investigation (if it lands) or sending back a potential threat (if it returns home). When jammed, the drone’s video transmission is also immediately ceased, so it can no longer transmit any footage to the operator.
The market demand for specifically anti-drone devices has risen as UAVs have exploded in popularity over the past several years.One of the major uses of the jamming technology is in guarding against a potential terrorist attack and for that reason the devices have seen a lot of success in the Middle East region.
While the jammers look like automatic weapons their functionality is quite different. Most block the drone’s ability to receive signals. Davos deployed the HP 47 Counter UAV Jammer which last saw action during Barack Obama’s visit to Berlin, Germany last year.
Another reason why a lot of schools have jammers is to trying to prevent the students from cheating. A cell phone can be an easy cheating device where they can get the answers from a person who has the information or from the internet. It is easy to use a cell phone jamming device, and all you need to do in order to get it started is to push a button in order to interrupt a chat or conversation. Once the device is on, the cell phone will not be able to catch any signal and the phone will lose its value and get the students back in the class.
