2018.02.05  Drones are not just toys-we need jammers

Why need drone jammer?


While some drone jammers shoot actual ballistics in hopes of damaging any unwelcome aerial visitors, most modern anti-drone guns use signal-jamming frequencies to confuse the incoming UAV. When a drone’s radio signals are interrupted or continuously jammed, the UAV either lands as a precautionary measure or returns back to its origin. Either way, the goal has been accomplished—your drone blocker got rid of the intruder.


The drone high power 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.


Drones may invade privacy


The invasion of privacy using a drone will be a clear cut criminal offence. Moving to criminalise the use of drones for any sort of anti-social behaviour empowers the public and private businesses to protect themselves against this behaviour. The single greatest drone defence is drone jamming. Drone wifi jammer already in use in sensitive areas surrounding government property and in some cases industrial property too. Legislation will soon be in place and a drone capture using drone jamming will tip the balance in favour of those on the right side of the law. Once a drone has been captured it can be electronically identified and the operator traced to source.


LOJACK Blocker


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.


Jamming is regularly recognized from interference that can happen due to device defects or other accidental events. Devices that easily cause interference are regulated under various regulations. Jamming happens when an operator transmits on a busy frequency without first checking whether it is busy, or without being able to hear stations using the frequency.


There are some techniques to identify and stop these sorts of attacks. Wireless intrusion prevention systems (WIPS) can make the signal jammer apparent, WIPS is a network device that monitors the radio spectrum for the presence of unauthorized access points (intrusion detection), and can automatically take countermeasures (intrusion prevention). Some radio-based devices support spread spectrum modulation so that hardware can cycle through different frequencies to make the devices harder to jam.
