How to jam the drone signal?

As drones are being taken into more and more environments some people do not like the idea that drones are able to fly freely, citing privacy and security reasons for greater control over drone flying locations. The majority of drone legislation and enforcement relies on the drone pilot doing the right thing. That is, understanding the most up-to-date drone regulations and rules for the jurisdiction that they are flying in, having up-to-date information about no fly zones, and using that information to fly responsibly and within the law. Should this not be enough, there is the potential to jam a drone signal which can cause the drone to simply return to its take-off location.

What is a drone Jammer?

A drone jammer is a piece of technology which sends a disturbance signal to interfere with the normal signal the drone is receiving from the remote controller (operated by the drone pilot). These signals are sent at high outputs in order to cause interference in order to make the drone lose all ability to communicate via radio signals with the remote control.

A drone that is not able to communicate sufficiently with the remote control will often simply return to the take-off location through an advanced technology called “return to home” found in most consumer grade GPS drones. By following the drone back to its take-off location, law enforcement are also able to identify the drone pilot.

When would someone use a drone jammer?

There are plenty of activities where using a drone becomes a very useful tool. This includes aerial photography, disaster monitoring, agriculture, industrial inspection, retail, and much more. As well as these activities drones can be used in hostile missions in order to cause injury or collect sensitive information.

For example airports and crowded urban areas such as football stadiums need to be on the lookout for drones which may be carrying explosive devices or biological agents.

Drones can also be used for spy missions, where they can capture images and topographical data about sensitive areas. Moreover, drones can also be used for smuggling illicit materials over borders or into and out of prisons – there are so many ways that a drone can be used for malicious intent.

Anyone who wants to protect themselves or the information against drone attacks could use a drone jammer. Reliable drone detection is very difficult and demanding task. The fight against hostile drones consists of two phases. Drone detection and drone jamming.

A drone jammer protects land, property, information, and privacy by making the drone inoperable by its pilot.

How do drone jammers work?

As mentioned above, drone jammers work by sending out a much more powerful signal than the remote controller. In Europe, the following radio bands are allowed for remote controls: 27 MHz, 35 MHz, 40 MHz, 433 MHz, 2.4 GHz and 5 GHz.

There are two different types of remote controls, analogue – using a pulse width modulation, and digital – using digital modulation techniques. The digital modulation techniques are more familiar and give rise to the 2.4 GHz and 5 GHz bands which would be familiar to anyone operating a drone.

Besides the control commands you are also able to jam other radio signals such as flight data and status to the remote controller, the video link for sending images to the remote controller, and the global positioning system which is required for the drone to auto stabiliser and hover.

The aim of jamming is to distort the signal to a level where the receiver is completely unable to detect it or at least achieve some parts of the system losing their integrity resulting in the total or partial denial of service between the drone and the controller. Disabling a drones GPS system is one of the most effective ways of disabling it.

Who would want to use a drone jammer?

There are a range of use cases for who may want to use a drone jammer. This includes security personnel, military personnel, homeowners, private property owners, and wildlife or park rangers.
