Non-Kinetic Soft-Kill Counter-UAV Techniques

Non-kinetic counter-unmanned aerial vehicle (C-UAV) measures operate by disrupting or intercepting communication signals. These techniques often result in the drone descending rapidly, making them inappropriate for use in crowded areas. However, they can be effective in other settings. It is essential to review the legal regulations in your country regarding drone countermeasures, as drone jammers and spoofers are prohibited in the United States. Let us explore various non-kinetic C-UAS strategies.

What are drone jammers?

Jammers function by generating electromagnetic interference on the radio frequencies utilized by drones for operation and communication. This interference effectively disrupts the dialogue between the drone and its operator. The frequencies commonly involved are 2.4 GHz and 5.8 GHz, which are public frequencies that are not assigned to specific uses. Consequently, this design ensures that the jammer does not interfere with manned aircraft, cellular devices, public broadcasting, or other designated radio bands.

Jammers may be either stationary, installed devices or integrated into portable, firearm-like apparatuses that enable an individual to safely bring a drone to the ground.

What happens when a drone gets jammed?

• Will the drone land, or
• Will the drone return to its location

What are the drawbacks of drone jamming?

The Federal Communications Commission (FCC) has stated that the use of drone jammers is prohibited in the United States.

The use of a 'cell phone jammer' or any comparable device to intentionally obstruct, disrupt, or interfere with authorized radio communications is a breach of federal law. Such devices, including signal blockers, GPS jammers, and text blockers, present significant dangers to essential public safety communications, potentially hindering individuals from making 9-1-1 and other emergency calls. Additionally, jammers can disrupt communications utilized by law enforcement agencies.

The use of a jammer within the United States may lead to substantial financial penalties, confiscation of unlawful devices, and legal repercussions, which could include incarceration.

Applicable Law

Communications Act of 1934

• Section 301 - Requires a person who operates or uses a radio transmitter to be licensed or authorized pursuant to the Commission's regulations (47 USC § 301)
• Section 333 - Prohibits intentional or malicious interference with the radio communications of any station licensed or authorized under the Act or operated by the United States Government (47 USC § 333)
