About this app

FORSYTE helps you see the invisible radio signals around you.

Wireless technologies are everywhere. Aircraft, radios, emergency beacons, drones, and countless everyday devices all transmit signals through the radio spectrum.

FORSYTE works like an early-warning system for radio activity, alerting you whenever signals appear nearby and helping you visualise activity across the spectrum in real time.

Whether you are investigating interference, exploring the airwaves, or working with wireless systems, FORSYTE provides immediate insight into the RF environment.

FORSYTE can help reveal many different types of wireless activity, including:
• Emergency and distress beacons (SOS signals)
• Aircraft and aviation transmissions
• Broadcast radio signals
• Drone and remote-control links
• Interference or unusual RF activity
• Industrial, IoT and wireless device signals

The radio spectrum is used by thousands of technologies, and FORSYTE helps you understand when those signals appear.

Key features:
• Real-time radio signal detection
• Spectrum visualisation tools
• Signal alert notifications
• Detection history and logging
• Configurable monitoring modes
• Built-in signal reference library

Who may find FORSYTE useful:
• Security and safety teams
• Search and rescue personnel
• RF engineers and technicians
• Drone operators

• Radio hobbyists and researchers

or anyone interested in understanding the wireless signals present in their environment.

Hardware requirements:
