A revolutionary RF signal analysis platform
Identify and track drones in real-time using radio frequency signatures
See WiFi signals through physical barriers like walls
Advanced radio frequency monitoring and signal processing
Protect airspace and detect unauthorized devices
From security to research
QuadRF uses advanced RF signal analysis to detect drones by their unique radio signatures. Unlike traditional methods that rely on visual or acoustic detection, RF analysis can identify drones even in low visibility conditions.
The system captures and analyzes communication signals between drones and their controllers, providing real-time tracking and early warning capabilities.
Detect drones before they become visible
One of QuadRF's most remarkable capabilities is visualizing WiFi signals through physical barriers. By analyzing RF propagation patterns, the system can map out WiFi presence and signal strength even through walls.
This technology opens up possibilities for:
• Network troubleshooting
• Security auditing
• Building signal mapping
• Research applications
