Abstract
Over the past decades, unmanned aerial vehicles have been used for an increasing number and variety of purposes. With the increasing popularity of unmanned aerial vehicles, their use for illegal purposes has also emerged. Therefore, there is also an explosive growth in the field of counter-drone technologies.
The aim of the study was to examine the usability of the NEROD RF® portable counter-drone device in Hungarian law enforcement environment. In July 2024, we carried out usability testing in Budapest. In this research, we investigated the usability of the counter-drone device in law enforcement environment in a less formalised way, by collecting qualitative data. A SWOT analysis was carried out to assess the results.
The counter-drone device could be quickly deployed by a single operator (<60,0 s). The device was able to interfere with the communication protocol between the drones and the drone pilot in the 2.4 GHz frequency range for all measurements. In all cases, signal interference occurred in 0.0-5.0 seconds (s).
The counter-drone device can be used in professional fields where: (1) the threat from drones is high; (2) the use of deployed counter-drone system is not possible or not justified; (3) mobility is important; (4) radio frequency signal interference does not compromise the operation of other devices.
