In BVLOS operations, which technology is essential for long-range communications?

• A. Relay/satellite
• B. Bluetooth
• C. Infrared
• D. Short-range UHF

Answer: (A)

In BVLOS operations, you need a communications link that works well beyond the operator’s line of sight. Relay or satellite links provide that long-range, reliable reach, letting the drone stay connected for control and telemetry over vast distances or in challenging terrain. They’re designed to maintain connectivity when the drone is far away, high up, or out of direct line of sight.

Short-range options like Bluetooth or infrared simply don’t cover the distance or withstand obstacles. Short-range UHF might extend range somewhat, but it isn’t inherently built for global, reliable BVLOS connectivity and can be limited by terrain and bandwidth.
