BVLOS Communication Methods
Reliable and secure communication systems are the backbone of BVLOS drone operations, ensuring the continuous transmission of command, control, and telemetry data. The two primary technologies enabling BVLOS communications are cellular networks and satellite communications (SATCOM).
Cellular network integration

Leveraging existing 4G LTE and emerging 5G networks, cellular-based BVLOS communications provide high-bandwidth, low-latency connections suitable for urban and suburban environments. Cellular networks enable drones to transmit real-time telemetry data, high-resolution video feeds, and sensor data back to the control station. The high speed and low latency of 5G networks, in particular, make cellular integration an ideal solution for applications requiring precision and responsiveness, such as drone delivery and security monitoring.
Cellular network integration is also cost-effective, as it utilises widely available infrastructure. However, coverage limitations in rural or remote areas can necessitate the use of other communication methods, such as SATCOM.
Satellite-based communications (SATCOM)
SATCOM is indispensable for BVLOS operations conducted in remote regions where cellular infrastructure is unavailable. Satellite communication systems provide global coverage, ensuring uninterrupted connectivity over oceans, mountains, and deserts. SATCOM for drones is particularly crucial for long-range missions like offshore infrastructure inspection, wildlife monitoring, and border surveillance.
Many BVLOS communication systems employ a hybrid approach, combining cellular and satellite technologies to optimise performance based on the mission’s location and requirements.
