OTA test methodologies for resilient drone communication using Bluetest reverberation chambers

Unmanned aerial systems (UAS), commonly referred to as drones, have rapidly transitioned from consumer novelties and commercial workhorses to critical instruments in modern warfare. Their cost-effectiveness, agility, and operational range make them formidable assets on the battlefield. However, their reliance on wireless links—both for command and control (C2) and video transmission—is a key vulnerability.

In environments with electromagnetic interference, the resilience of these wireless links can determine the outcome of a mission. Today, adversaries equipped with electronic warfare (EW) tools are targeting these command-and-control channels with increasing precision. Therefore, the need for rigorous, repeatable, and realistic Over-The-Air(OTA) testing is more urgent than ever.

This White Paper outlines a practical approach to testing drone communication systems using reverberation chamber (RC) technology from Bluetest. This unique measurement system provides a fast and repeatable way to test real-world device performance under diverse and challenging RF conditions.
